The most common way to decorate a ceiling is to whitewash or paint it. And the most used paint for this is water-based paint. Painting the ceiling water-based paint at first glance it seems like a simple matter, but there are many subtleties, ignorance of which leads to the appearance of spots or streaks. We will tell you further how to avoid such troubles.
Preparing for painting
In order for self-painting of the ceiling with water-based paint to be high-quality and uniform, it is necessary preliminary preparation ceiling. Uniform coloring can only be achieved on a flat, puttied surface. Therefore, before starting work, you need to clean the ceiling from any previous coating (with the exception of water-based emulsion, which holds up very well).
How to remove whitewash
If you have whitewash on the ceiling - chalk or lime - you need to moisten the ceiling with water and remove the coating with a spatula. They clean everything down to concrete. Even the smallest fragments must be removed. Sometimes it is very inconvenient to scrape small areas with a spatula; it is easier to do this with a wet cloth.
In any case, after removing the whitewash, the ceiling must be washed with water detergent. After complete drying, prime and putty with gypsum or cement (preferably white) putty until smooth, which is also called “egg-like.”
How to remove old water emulsion
If the ceiling has already been painted with water-based emulsion, you won’t be able to simply remove it. The procedure depends on how the paint adheres to the ceiling. If it just changed color and you need to renew the ceiling, there are no swelling, cracks or other similar problems, you can get by with a little blood. First, remove the dust (with a cloth and water), dry it, then prime it. After the primer has dried, you can paint it. But once again we draw attention to the fact that this procedure is used only if the water-based emulsion holds well and there are no defects.
Cleaning waterproof emulsion from the ceiling is still a pleasure
If there are cracks or swellings on the surface of the water-based emulsion, it must be cleaned off. There are two ways - dry and wet. Dry means cleaning with sandpaper (manually or using an angle grinder), wet means washing off. This method must be used for paint that is not afraid of water. But it is very difficult to remove such paint. If the water-based paint holds up well, no tricks help, but there are surface defects and putty is needed, take sandpaper with a coarse grain and make the surface rough. After this you can putty. Next - according to technology: we prime and then paint.
Wash off the ceiling painted with water-based emulsion by wetting it generously twice. hot water. The water should be almost boiling water - about 70°C. After wetting part of the ceiling, wait 10 minutes, then wet the same area again with hot water. After about five minutes you can remove the paint with a spatula.
Removal old paint- long process
You can repeat this procedure several times, gradually removing loose paint from the ceiling. Small residues can be sanded off, and then the ceiling can be washed, dried and primed. You can putty and sand over the primer, smoothing out imperfections.
Types of water-based paint
Water-based paint is a water-based emulsion that contains polymer particles undissolved in water. The composition also includes pigments and various additives that change the characteristics of the final product. After applying the paint, active evaporation of water occurs and a thin polymer film remains on the surface.
Painting the ceiling with water-based paint begins with choosing the composition. They use four types of polymers:
- Acrylic. An aqueous emulsion based on acrylic resins allows you to obtain flat surface, has good hiding power, hides small surface defects, even cracks up to 1 mm wide. Its disadvantage is high price, but it’s easier to work with. In its purest form acrylic compositions They are hygroscopic and can only be used for dry rooms, but they do not interfere with the passage of steam. To create a waterproof film, latex is added to the acrylic water-based emulsion. The same additive increases the elasticity of the dried film. Such compositions can be used in damp areas.
Water emulsion on acrylic base- a smart choice
- Silicates. This type of water-based paint is based on liquid glass. The coating is resistant to precipitation and at the same time does not interfere with the removal of vapors, has a long service life (10 years or more), and can be used for outdoor work.
Silicate paints are vapor-tight
- Minerals - lime or cement. Mineral water-based emulsions have good adhesion to any surface, but are quickly washed off. As a result, they are gradually losing popularity.
- Silicone. Silicone-based water emulsions are the latest achievement in the industry. These compositions are good because they “tighten” cracks up to 2 mm thick. As a result, the surface painted by them, even without excellent preparation It turns out even and smooth. The film turns out dense, but vapor-permeable. Silicone water-based emulsion can be used to paint ceilings in bathrooms and other wet areas. The disadvantage of this type of paint is its high price.
Latex can be added to any of the compositions. Latex water-based paint is water-repellent. It is not afraid of moisture and can be used in damp rooms.
Based on the main characteristics of these compositions, you can choose for yourself best type water-based paint. Each case requires its own properties and the “best water emulsion” is different each time.
What primer to use
A primer is necessary for better adhesion of the paint to the surface being painted. It allows you to avoid the appearance of cracks and blisters after the paint dries. If there is no primer, this can happen. You'll have to clean everything off and putty again. Because in order for painting the ceiling with water-based paint to be of high quality, the surface must be well primed.
The base of the primer should match the base paint. Acrylic water-based paint requires the same primer; silicone paint requires a silicone-based primer, etc. Moreover, it is advisable not to save: the quality of this composition determines how smoothly the water-based emulsion will lie on the ceiling.
Eat economical way primers: the base paint is diluted with water (1 to 2) and the surfaces are painted with this mixture a couple of times. It's certainly better than nothing, but the primer gives a better grip.
How to paint a ceiling with water-based emulsion with your own hands
Each of the water-based paints has instructions for use on the can. The operating procedure is described there. Some compositions just need to be stirred well before use: undissolved polymers may settle at the bottom of the jar. Some formulations require dilution. The amount of water added is also specified in the instructions and depends on the application method. For spray guns, the dilution is stronger; when using a roller, thicker formulations are required.
When diluting the emulsion with water, add it in small portions. Stir thoroughly and try on a surface area. If the paint goes on evenly and almost completely covers the base, you can paint.
It is more convenient to pour the paint into a special container with a tray and a ribbed platform. You can use a regular basin and a clean piece of oilcloth spread nearby. It's not as convenient, but less expensive.
Which roller to choose
A roller for painting the ceiling with water-based emulsion is needed with dense short pile. You need to examine him carefully. The pile should “sit” firmly and under no circumstances should it “climb out”, even if you pull on it. Then inspect how the seam is made. Under no circumstances should he stand out. It must be difficult to find. It is best if it is made obliquely.
Pay maximum attention to choosing a roller: the quality of painting - the absence of stripes on the ceiling - largely depends on how good a tool you have chosen. It is more convenient to whiten the ceiling with water-based emulsion not from a stepladder, but from the floor. To do this, the roller is placed on a long handle and secured well.
How to paint without streaks
To avoid streaks on the ceiling, painting the ceiling with water-based paint should be completed no later than in 20 minutes. Immediately after application, water begins to actively absorb/evaporate and stripes appear at the junction of the dried and “fresh” paint. Therefore, it is advisable to prepare the room. It is necessary to turn off (wrap up) the heating radiators and prevent a draft. It is also advisable to wash the floor immediately before whitewashing; even if you work during the day, turn on the lighting, this will allow you to better control the quality of the paint. Afterwards you can start working.
Ready-to-use water-based paint is poured into a container, a roller is dipped into it, then rolled well over the site, achieving uniform distribution over the entire surface. When the roller has a uniform color, they begin to paint.
The corners are painted first with a brush. After applying a little paint, take a small roller and roll it out well. Then they begin to paint the main surface. The first layer is applied parallel to the window, the second - perpendicular.
You need to stand so that you look at the area to be painted at an angle. This will give you a good look at how evenly the paint has spread, as well as where you have already painted and where you haven't. Move systematically, without jumping from one piece to another.
The width of the strip painted at a time is slightly larger than the width of the roller. After wetting the roller, place it approximately in the middle of the strip. Quickly roll the paint in both directions from one wall to the other. Don't waste a lot of time: you don't have much of it. On average, the water emulsion dries in 10-20 seconds. If you didn’t have time to apply the strip next to it before, the border will be clearly visible, which you won’t get rid of. Having distributed the paint more or less evenly over the strip, dip the roller into the paint and roll it out again from the middle of the ceiling. At the same time, go beyond the already painted strip by about 10 cm. All this at a good pace without stops and smoke breaks. The edges of the painted strip should not dry out. In general, these are all the rules.
After applying the first coat of paint, some areas may not be painted as well. You need to wait for it to dry completely and paint it a second time. This should already be enough to obtain a flat surface. If even after the third layer of water-based paint you still have streaks and stains on the ceiling, you will have to redo it again. It is necessary to level the surface with sandpaper, prime it again and paint again.
What color
The easiest way to achieve perfect evenness of color is to use “snow-white” paint. All pigments clearly highlight even small irregularities, so you need to pay maximum attention to the process or use an acrylic or silicone-based water emulsion.
When starting to renovate their home, be it an apartment in the city or a house in the countryside, any developer understands that finishing the ceiling remains a rather difficult stage in the work. Today there are all sorts of solutions for the ceiling: cladding ceiling tiles or wallpaper, hanging and suspended ceilings. But not every owner can afford such options. Since the cost of painting the ceiling with water-based paint is quite affordable, this type of finishing still remains relevant. And if you use the most ordinary roller for work, then even more so.
Choosing the right painting tool
Since most ceilings are large and flat surfaces, the most a practical tool Use a paint roller to apply paint. You can, of course, paint the ceiling with a brush, but all the strokes will be obvious, and for the ceiling such a picture is completely unacceptable, since it will be perceived as unevenly painted. Therefore, it is customary to use a brush only for painting corners and hard-to-reach areas.
There are quite a lot of them on the construction tools market today. different types, which makes the selection procedure difficult for beginners. These are velor, foam and fleecy rollers. The price for them is not very different, which can be misleading about their supposedly identical qualities. But the differences are actually very significant. And the chosen roller will have a greater influence on the painting of the ceiling.
Of all the different types of rollers, the best result is achieved when using a roller with pile (threads). In such a situation, foam rubber is not suitable due to the fact that it absorbs too much paint, which accumulates on the ceiling surface, and because of this, bubbles appear on it. But velor tools take little paint.
If you are going to paint a large area, the important point is to choose the largest possible roller, since we are talking about the area paint surface. You can also paint the ceiling with water-based paint using a spray gun, but today we will talk about the simplest option.
It is best to choose a medium-sized roller pile because a large one absorbs too much paint and thereby applies a fairly large layer of paint, while a small pile will most likely leave unpainted areas. The rougher ceiling surface, then you need to choose a longer pile at the roller so that the paint covers the entire texture and fills all the recesses. We also recommend that you do not use rollers with a bolt-on handle or made of foam rubber, because they quickly fail.
In addition, you should know how rollers are selected experienced craftsmen, and how to distinguish a high-quality tool from a low-quality one:
- When choosing a roller, it is recommended to squeeze it in your hand: in this case, a high-quality roller will not be deformed as a result of compression.
- Carefully inspect the seam on the roller: quality product The fabric does not have an obvious joint, since such seams can leave stripes on the ceiling during the painting process.
- Test the strength of the lint by pulling it towards you: a high-quality roller will not allow a single lint to stretch out, while cheap fakes will leave a noticeable clump in your hand.
Under your roller, you need to choose a plastic painting container into which paint is poured and where the substance is then rolled out with a roller. Remember that if you simply dip a roller into a bucket of paint, you may not expect a beautifully painted ceiling! In order to use a roller from the floor without using scaffolding, you need to purchase a special telescopic tube. With such a long folding handle you can reach anywhere you need.
To access different corners, as well as similar places to corners, use a brush. For this type of work, a flute brush is used. IN retail trade There are special types of this tool. These brushes do not leave characteristic streaks behind and provide almost the same result as a roller. Regarding the width of the brushes, it is better to purchase a brush with a very small thickness (3 centimeters) and a slightly wider tool (8 centimeters).
Removing old finishes from ceiling surfaces
Before painting the ceiling surface with water-based paint, you need to do preparatory work and protect floors, window sills, radiators and furniture from splashes and dirt (it’s better to take it out altogether). You can cover them plastic film, newspapers or cloth, secured with low-adhesive tape. It also needs to be used to glue the walls around the perimeter, risers of gas and heating pipes. This one is sticky paper tape Easy to remove and leaves no traces behind. You can remove it as soon as the paint thickens.
After this, the ceiling should be freed from layers of old paint or whitewash. In order to get rid of lime or chalky whitewash, you need to moisten it generously with water using paint roller, then scrape off using a steel spatula or chisel. Finally, wash the ceiling with a sponge.
To update a ceiling painted with water-based paint, you need to spend more time on preparatory work. All this is due to the fact that the process of removing old paint is labor-intensive work, since the previous layer is practically insoluble in water, and therefore it is not possible to completely scrape off the ceiling.
Such work most often involves removing peeling paint with a spatula, as shown in the photo about painting the ceiling with water-based paint. To make this not entirely pleasant job easier, you can use the following technique. Wet the previous coating with plenty of water using a foam roller or water spray. This procedure must be repeated twice with an interval of twenty minutes.
The moisture should thoroughly saturate the previous coating. After this, you need to create a draft by opening all windows and doors. The layer swollen with water forms swellings of the old water-based paint, which are not difficult to remove with a spatula. This kind of work needs to be done fairly quickly so that the surface on which the work is being done does not have time to dry. Next, you need to treat rust and stains from smudges with a 5 percent solution copper sulfate.
If there are difficult-to-remove stains on your ceiling, you can use next lineup: two or three percent hydrochloric acid solution (gently wipe the stains, being careful not to get it on the skin). The following recipes are also known: a solution of twenty parts of crushed lime, which is diluted with one part of drying oil, a thick solution of lime and water with the addition of denatured alcohol (about 50 ml). Any of the last two mixtures is applied to the contamination for 10 - 15 minutes. And you repeat all this until the contamination is completely removed. Usually two procedures are enough.
Leveling the ceiling before painting with a roller
After the ceiling surface is completely cleaned, it needs to be leveled. For this purpose, thin-layer putty, which has good adhesion properties, is best suited. It has excellent ductility and gives an almost flat surface that can be easily processed with fine-grained sandpaper. Using a spatula, the substance is applied to the ceiling. Quite often, the ceiling is leveled by applying putty-whitewash on an oil-adhesive basis, which is distributed evenly over the surface using a brush, spatula or roller.
Remember that you must first seal all the cracks and cracks in the ceiling by first watching a video about painting the ceiling with water-based paint and filling them with a specially prepared composition. To completely fill the cracks with putty, they must be widened before application. The next preparatory operation is priming the surface, which is done with the same paint. It is applied very thin layer, then the composition is allowed to dry thoroughly so that the putty does not come off.
Preparatory work before painting the ceiling
To begin, open the prepared paint and, in accordance with the instructions, dilute the paint to the desired thickness. Manufacturers very often recommend adding approximately 5-10% water to the solution. If the manufacturer does not recommend diluting the paint, then you just need to mix it. This is easily done using a mixer attachment on an electric drill. To paint the surface in one layer, this mixing will be quite enough.
You cannot use the roller with which you applied the primer to paint the ceiling with water-based emulsion; it is better to take a new one or replace the coat on the old one. Take the roller in your hands and dip it into the bowl of paint. It is important to note that, according to the technology of painting the ceiling with water-based paint, you should not completely lower it into the container, but only dip it. The roller usually gets wet on one side and the wet edge becomes heavier. But you need to ensure that the entire circumference of the tool absorbs the paint evenly.
To do this, you roll out the roller along the trough ( special dishes, which is sold in special painting kits), mesh or a clean sheet of hardboard, linoleum, but not on the ceiling surface. By slightly pressing the roller onto the sheet, you can evenly saturate its entire surface with paint. After this, you need to dip the roller in the paint again and roll it out again. If suddenly you fail to wet the roller evenly, then upon completion of the repair, unpainted areas will appear. After drying, it is they that form the unfortunate spots that we talked about at the very beginning.
Sufficiently experienced painters do this automatically, but you, of course, need to practice. This kind of work is not very difficult, but you need to be careful here. For greater confidence, you can practice on a section of an unprepared wall, a piece of drywall, or any surface that you don’t mind using for the experiment.
Painting the ceiling with water-based emulsion using a roller
As soon as you have rolled out the roller and the threads are evenly filled with paint, start painting the ceiling with water-based paint. It is better to carry out all work during daylight hours, starting from a distant corner. The main thing to remember is that the paint needs to be applied evenly to the ceiling surface, without delaying the whole process. Upgrading the ceiling even in a large room takes only 15-20 minutes.
Water-based paint must be applied to the ceiling in parallel stripes. Try to make stripes that are about 50 centimeters wide. You need to paint overlapping, each new strip should overlap the previous one by 8 - 10 centimeters. Rub the paint thoroughly and make sure that the edge of the paint does not dry out on the layer.
When working, do not lift the roller from the surface, increasing the pressure as you use up the paint. The marks from the edges of the roller must be rolled out in a perpendicular direction. If you plan to paint the ceiling with water-based paint in several layers, then remember that the last layer should be placed in the direction of the windows, and the previous one in a perpendicular direction.
To paint the corners of the ceiling you need to use a brush. Dip it into the paint one-third and squeeze out the excess mixture on the edge of the can. Using thin strokes, apply the paint around the perimeter of the ceiling in a strip that is about 5 centimeters wide, and rub thoroughly. The result will be a thin and even layer, which will later merge with a fresh layer of paint on the main surface.
Painter, painting ceiling, looks at him at a right angle and does not see the place where he has already “walked” with a roller. His vision also does not allow him to see how many times he touched a certain area with the roller. For him, the entire ceiling acquired a damp, uniform shade and therefore visually it seems that the entire surface is painted the same way. This is where another mistake is hidden. In this case, painters with extensive experience sometimes step aside and look at the ceiling from a different angle, as unpainted areas immediately become visible.
When imperfections arise, they must be dealt with. It happens that stains remain even after your efforts to resuscitate the ceiling. Further work is useless and only leads to waste of material. This kind of work needs to be redone. The only way to correct errors is to sand the entire ceiling with fine sandpaper. If you painted only 1-2 layers, then everything will work out. But if you went through a lot more with a roller, you will have to sand and putty and re-paint everything.
Eliminate all drafts in the room, curtain the windows to avoid direct contact with the ceiling surface. sun rays. You cannot use additional heating devices in order to speed up the drying process, because temperature regime in the room must fully comply with the instructions indicated on the label of the can of water-based paint.
And finally, remember that you should not focus only on the low price of painting the ceiling with water-based paint, you must strictly follow the technology! It is best to do the work in the afternoon so that you can repeat the process in the morning. Remember that the surface must dry thoroughly after each coat of paint. If the first layer is not allowed to dry, the second will become wet and lift the existing paint.
Finishing the ceiling when renovating a room is important stage all the work. Defects in the ceiling surface are immediately apparent, because it is an open structure; it cannot be covered with furniture or covered with carpets. ABOUT proper preparation and painting the ceiling with water emulsions - our article.
Contents of the article:
Unlike conventional whitewashing, the snow-white appearance of the surface after painting the ceiling with water-based paint lasts much longer. In addition, the surface coated with such material can be washed, which is an important factor. The moisture resistance of the paint is given by the environmentally friendly polymers included in its composition. However, not all its types have this property.
Types of water-based paints for ceilings
The consumer market offers paint and varnish compositions based on aqueous emulsions, which differ in composition, price and purpose:
- Polyvinyl acetate paints. This is the most cheap material. It is used exclusively in dry rooms; ceilings cannot be washed after painting.
- Paints with additives liquid glass . Used for finishing concrete and plastered surfaces.
- Silicone paints. They can be applied to the plastered ceiling surface without prior priming. Such paints serve to protect structures from fungi and other microorganisms and have high vapor permeability, which makes them possible to use for painting ceilings in bathrooms and kitchens.
- Water-based acrylic paints . The most popular material. It can be used in any room. Ceilings painted with this paint are highly wear-resistant when cared for and are not afraid of moisture.
- Acrylic latex paints. More expensive of all of the above. In the process of painting the ceiling, they give a smooth and beautiful surface, perfectly fill cracks up to 1 mm thick. Ceilings can be washed using gentle detergents.
Choosing water-based paint for the ceiling
For the right choice water-based paint, you need to read the instructions written on the product packaging. The manufacturer indicates in it the type of work for which the material is intended, its consumption per 1 m2, wear resistance during wet cleaning, the recommended number of layers, etc. For painting ceiling surfaces there are special types water-based paints that do not drip from above when doing work and have good adhesion.
In addition, paints come in matte, gloss, semi-matte and semi-gloss. Using matte paint increases the height of the room and masks small unevenness in the ceiling. But the surface painted with such material is difficult to wash. When using glossy paint, imperfections will be visible on the ceiling, but it will be easier to care for. The best option A choice of semi-matte or semi-gloss paint may serve the purpose.
Any paint cannot withstand freezing and thawing cycles - its structure is damaged in such conditions and is no longer restored. Therefore, it would be correct to buy such material in a store that has an insulated warehouse.
Cleaning the ceiling before painting with water-based paint
Before preparing the ceiling for painting with water-based paint, you need to remove everything unnecessary from the room: cabinets, tables, equipment, etc.
The old layer of ceiling covering can be in the form of whitewash or paint. Therefore, the methods for removing it differ. In the first case, the surface must be wetted with water using a roller, and then the lime layer must be removed with a spatula or scraper. The procedure should be completed by rinsing the cleaned ceiling using a sponge.
As for removing old paint, you won’t be able to wash it off with water. The only option is to scrape off the peeling areas of the coating. To make the work easier, you can generously moisten the painted ceiling with water, giving the old paint an opportunity to swell, and then remove its swelling on the wet surface with a spatula. For better swelling of the coating, a draft is created in the room.
Stains of various origins present on the ceiling can be removed with a three percent composition of hydrochloric acid, a five percent composition of copper sulfate or a solution of lime with the addition of 50 ml of denatured alcohol.
Leveling the ceiling for painting with water-based paint
Alignment is performed after completion of the first stage of work. To eliminate unevenness and give the surface a smooth shape, fine-grained gypsum putty is used. It has excellent ductility and adhesion to many types of coatings. Before its continuous application, the ceiling surface must be dust-free and primed, and all its cracks must be cut and puttied.
The application and distribution of putty on the ceiling is done using metal spatulas. There should be two of them: a wide spatula is used to do the main work, and a tool with a narrower working surface is used to collect the mixture from a container and distribute it along the plane of a wide spatula before applying it to the ceiling.
After leveling the ceiling and drying the putty, its surface is sanded with a special abrasive mesh with small cells until it is absolutely smooth. Sanding creates a lot of dust, so it is recommended to cover the floor of the room with film. All furniture, of course, is removed before work begins.
Features of priming the ceiling before applying water-based paint
The primer is needed for adhesion of the ceiling base with the putty applied to it and the planned painting material. It is carried out on a surface that has been cleaned of old coating and before painting it.
Special compositions with an alkyd or water-based base are used as primers. In addition to adhesion, priming increases the strength of the ceiling base, prevents its destruction and significantly reduces paint consumption at the main stage of work.
Priming is done using a brush, this allows you to handle the unevenness of the ceiling and thoroughly saturate its surface with the material. The composition is applied in 2-3 layers, each of them is kept until dry. After grouting the leveling layer finishing putty on the ceiling, priming before painting can be done from the floor with a roller attached to a long handle.
If the surface is infected with fungus, a special antiseptic primer is first applied to the ceiling. It contains substances that prevent the appearance of microorganisms.
DIY ceiling painting with water-based paint
Before painting the ceiling with water-based paint, it is necessary to stick masking tape along the perimeter of the border of the surface to be painted to prevent unwanted contact of the material with areas of the walls of the room. Work can begin even after noon - overnight the ceiling will dry and be ready for the second coat of paint.
Preparing tools for applying water-based paint to the ceiling
The production process requires the following tools:
- A roller with a shell made of synthetic or natural fur.
- A flat paint brush 3-4 cm wide for painting places that are difficult to reach for a roller - corners, junctions, etc.
- A cuvette with a ribbed surface for an even distribution of paint onto the roller.
- Telescopic handle roller for comfortable work from the floor.
The foam working surface of the roller is not suitable for painting the ceiling with water-based paint. It disrupts the uniformity of the coating, covering it with air bubbles.
Applying water-based paint to the ceiling
For high-quality painting of the ceiling, you must follow these rules:
- Work should begin with the joints of the ceiling and walls, as well as corners, the first of which should be the most distant from front door. To do this, with a paint brush dipped in paint, make a passage up to 5 cm wide along the perimeter of the ceiling. This will allow you to carry out further painting with a roller without touching problematic components of the ceiling structure.
- The main painting is done in three passes with a roller mounted on a telescopic handle. The first pass is performed in a direction perpendicular to the plane of the window, the second - in a transverse direction relative to the rays of light entering the room from it. The last pass of the paint roller is always directed towards the window.
- Layering the ceiling involves applying fresh paint to a dried surface. Drying of one layer occurs within 8-12 hours.
- In a ditch with paint, moisten the roller, moving it 3-4 times along the grooved surface of the tray to evenly distribute the material over the working surface of the tool.
- From the left corner of the wall, which is located opposite the window, you need to make the first pass with a roller along the ceiling section.
- The movement of the tool should occur from left to right, then the direction must be changed. It is important to ensure that the material is laid down in an even, uniform layer with no visible transitions.
- Excess paint on the ceiling can be removed with a slightly wrung out roller.
- In the process of painting the ceiling, its quality can be checked using a bright beam of light directed at the floor at an angle to the surface from a flashlight or portable lamp.
- Before the last painting, it is recommended to replace the working surface of the roller with a new “coat”. This will improve the quality of the final paint coat.
How to paint a ceiling with water-based paint - watch the video:
Painting with water-based paint is one of the most popular ways to finish a ceiling. Its advantage is simplicity: a few strokes of the brush, and a neat, beautiful coating is ready. However, to achieve such a result, you need to strictly follow the technology. Let's talk about this in more detail.
Why water-based paint?
Important! If the ceiling is very dark, be sure to lighten it before painting with an appropriate primer. Otherwise, the base will show through the paint and even 3 layers will not be enough to make the coating snow-white. In this case, paint should be chosen with high hiding power.
What tools will you need to paint the ceiling?
To work you should prepare:
- Roller with medium pile. A short pile can leave streaks, while a long pile will pick up a lot of paint. Masters do not recommend using foam or velor rollers.
- Small flute brush for treating the ceiling near the junction with the wall.
- Painting tray with a corrugated bottom. Don't neglect it. The cuvette, unlike other containers, will help leave exactly as much paint on the roller as needed. This will help achieve an even layer without smudges.
- Fine sandpaper for grouting.
- Masking tape for pasting the borders of surfaces that do not require painting.
- If you do not plan to use a stepladder or sawhorse, you will need a telescopic folding handle for a brush or roller, with which you can reach the ceiling.
- It is advisable to acquire a bright portable lamp to monitor the transitions of paint on the surface and monitor the uniformity of the applied layers.
- Water-based paint.
If you plan to paint the ceiling with colored paint, then the white composition must be diluted with a color designed for water-based mixtures. When mixing, you need to take into account that the dried surface will be a couple of tones lighter than the liquid paint. The entire volume should be diluted: it is extremely difficult to obtain the same shade in different portions.
If you use tinting in a store, write down the paint color code. In the event that you need the same shade, it will be enough to purchase the same paint with which the surface was previously painted and tint it with the same shade. But it should be remembered that if the surface was painted a long time ago, the paint could fade and lose tone. In this case, choosing the same shade will be much more difficult. It might be easier to paint the entire surface.
Stages of work
So, it's time to start painting. For best result 3 layers need to be applied to the ceiling.
Step 1. Mix the paint, add water to it, if necessary according to the instructions, mix, pour into the bath. If there is a lot of paint, then you can use an electric drill with a mixer attachment for mixing. This must be done at low speeds so as not to whip the paint into foam. Some paint formulations need to be strained. This can be done using a nylon stocking or gauze.
Step 2. Paint with a brush the corners and places near the joints with the walls along the perimeter of the ceiling. The strip should be as narrow as possible - 7-8 centimeters. Process others hard to reach places behind the radiator pipes, around the wiring.
Step 3. Apply the first coat with a roller, applying stripes perpendicular to the window, from one wall to the other. You need to paint with wide, confident movements, making parallel stripes, with an overlap of several centimeters. You should act quickly without breaks or breaks, otherwise the composition will lie unevenly in places where there are breaks.
Step 4. Wait until the first coat of paint dries (usually no more than 2 hours).
Step 5. Evaluate the result. After applying the first layer it is still difficult to draw conclusions, but you can already notice unpainted areas.
Step 6. Apply a second coat of paint. Now the stripes should be applied parallel to the window, that is, layers of paint should be alternated in a perpendicular direction. Use a lamp to check the uniformity of the coating and carefully touch up the missed areas, if any.
Step 7. Wait for it to dry and apply the 3rd layer.
Important! When choosing the direction of painting, you must proceed from the following principles: the last layer must be done moving towards the window, with strokes along the sunlight, and each layer must be perpendicular to the previous one.
It is this application technique that will allow you to create a smooth, clean, uniform ceiling. It is better to apply the last layer with a new roller.
The most common problems and ways to solve them
Despite its apparent simplicity, painting the ceiling does not tolerate even the slightest carelessness. Most often, unsightly spots and stains remain on the surface, which appear especially clearly in bright light. The reasons are:
- poor surface preparation (the ceiling is not level, contrasting spots remain);
- non-compliance with painting technology.
In the first case, you will have to leave everything as is, or strip off the paint to the base and start the work again. In the second, you can try to correct the situation: apply another layer of more liquid paint, having previously sanded the surface with fine sandpaper. Didn't help? Everything will have to be redone. To prevent this from happening, when painting you need to pay attention to the following points:
- the composition must be mixed very well, otherwise the tone of the ceiling may not be uniform;
- the paint should saturate the roller evenly, for which it needs to be dipped and squeezed several times until it completely absorbs the mixture. They need to roll, not spread, paint on the ceiling;
- the paint should not be too thick, otherwise streaks may appear;
- there is no need to evaluate the exact result before drying: a “wet” ceiling looks completely different than a dry one;
- the next layer should be applied only after the previous one has completely dried.
Sometimes the paint starts to peel off. This is possible if the paint was too thick, applied in a thick layer, or the ceiling was poorly prepared. It is necessary to remove the peeling material, wash the surface, dry, prime and paint again.
Most often, attention is paid to the beauty and decor of the walls, unjustifiably forgetting about the huge influence of the ceiling on the overall perception of the interior. If we consider all the volumes of the room from the point of view of the surface that is open to the eye, then, unlike walls with furniture, the ceiling is completely open. Accordingly, it is the largest area of a room or room accessible to the eye. Whatever the quality, design and amount of money spent on wall decoration, it is impossible to create nice interior without a beautiful ceiling.
Painting is the final part of the design of the ceiling surface. Of course, it is not worth considering these days lime whitewash as a painting medium. As you know, it has the properties of crumbling, is easily contaminated and is inferior to modern paints in all respects. The industry has long stepped forward, and most modern means For painting the ceiling surface use water-based paint. From a decorative point of view, a matte finish will suit any interior. You can easily give any shade to your ceiling using special pigments. For example, giving it a warm shade for the most complete impression and comfort of the room. You can use cool shades to make the room feel more spacious and airy. And of course timeless classic- white matte ceiling. Next, we will talk in detail about the features of operation and application of water-based paint.
Features of ceiling paint
The popularity of painting the ceiling with water-based paint is due to its properties:
- non-toxic;
- no obvious odor;
- Possibility of application over old coating;
- high ease of use.
Even an inexperienced craftsman can use it to paint the ceiling surface. The equipment required for the work is simple and easy to clean upon completion of the work. If necessary, you can dilute the paint with water to obtain the desired consistency. It is permissible to use specialized tinting pigments to give various color shades required by the interior design. Let us also note the low cost of this product on the consumer goods market. finishing works. The combination of these properties has made water-based paint the most popular for many years.
Preparing to paint the ceiling
Before starting paint application work, a series of preparatory work. This will help you avoid additional complications and unnecessary waste time. First, a thorough inspection of the surface is carried out using special lighting “at an angle.” Using this method, you will be able to notice all the flaws and better assess the condition of the surface being examined.
In case of severe defects, it is necessary to carry out additional work to level the surface. Rough bumps, potholes and cracks cannot be corrected using paint materials alone. You will have to allocate additional time to eliminate such flaws. In this case, additional costs will arise for the purchase of leveling materials and appropriate tools. Old paint must also be removed. Only after the process of leveling the ceiling and drying it has been completed will it be possible to proceed to the next stage.
Painting over the old layer
It often happens that old paint is in satisfactory condition, does not peel off, but only has an unsuitable color shade. If the ceiling surface does not have visible cracks, potholes or waves, painting the ceiling can be done over the old paint, thereby significantly reducing the time and money spent on the entire work complex. If the ceiling already had a layer of water-based paint, and there are islands of peeling material on the surface, do not be upset. Unlike whitewashing, the layer of old water-based paint does not need to be completely removed. It is enough to limit yourself surface cleaning peeled segments, and you can safely proceed to the next stage - painting over the old coating.
The stage preceding the actual painting of the ceiling is the application of a primer. There aren't any special requirements. The stores offer a wide selection of primers suitable as a base for water-based emulsion. Price category The price of this product is also low and affordable.
Choosing water-based paint
The type of paint we are considering is a suspension of particles on water based. Simply put, water emulsion is an aqueous emulsion consisting of pigment particles and a binder base. This composition is extremely stable in its form and is difficult to disintegrate from external influences.
Let's look at the main types of water-based paint:
- On an acrylic binder base.
- On a silicate base;
- On a silicone binder basis;
- Mineral based.
The most common and in demand acrylic-based paint. As the name suggests, this paint contains acrylic resins, providing a balance between price and quality. The addition of latex substances gives the entire composition the property of elasticity. This ability ensures the closure of cracks on the treated surface. The size of cracks that such paint can cope with is no more than 1 millimeter. It is worth noting the increase in price provided by the addition of latex.
The silicone binder gives the paint increased water resistance and impermeability. Accordingly, this type of product should be chosen for surfaces of rooms with high humidity and dampness. For example, it is ideal for a bathroom ceiling. The composition of the paint, as the name implies, contains silicone resins, which determine these features. The size of cracks that the product in question can cope with increases to 2 millimeters. The cost is correspondingly higher.
The most unpopular type of water-based emulsion is paint based on a mineral binder. The flaw lies in the fragility of the surface created by this product. The reason for the composition is the content of slaked lime or even cement. The cost of the product is the lowest among other representatives of finishing materials.
So, the choice is not difficult. The modern industrial sector provides every opportunity to find the option that best suits your goals. When purchasing water-based paint, you should pay attention to the marking - coverability. The higher this indicator, the fewer layers you will need to apply to the ceiling to achieve an ideal result. On the label, the manufacturer often indicates recommended rooms in which the best results can be achieved by painting.
Stages of work
If we paint the ceiling over old decoration, preparatory stage will take minimal time. You just need to remove the peeling elements of the ceiling and, if necessary, putty it, filling all the cracks, crevices, and potholes. Next, a layer of primer is applied, and after it has completely dried, we can finally start painting the ceiling.
If you applied primer to the ceiling in the morning, afternoon is the time to start painting. By this time the primer will be completely dry. It is reasonable to apply the second layer of water-based paint the next morning.
