Is it possible to paint slate with facade paint? How and what is the best way to paint slate

Slate is the most popular roofing material, although it is inferior to others in decorative properties, and natural grey colour, over time, under the influence of precipitation, it darkens, which makes the roof nondescript, moreover, it starts to collapse.

To make the service life as long as possible, painting slate roofing , thus protecting it and giving the house an original look.

In the latter case, the result will also be positive, but additional work will have to be done.

Since slate is made of asbestos and concrete, its structure is partly similar to plasterboard and concrete slabs, so all painting work is carried out in the same way. Recommended to use the following types of paint:

Acrylic;
Polymer;
Solvent paint for slate.

Only these solutions will help give the roof new aesthetic appearance and at the same time, they will protect it from the harmful effects of ultraviolet radiation and precipitation.

The surface of the slate is necessary clean thoroughly using metal brushes to remove moss and dirt growths, rinse with water if necessary; if there are holes in the roof, then these areas should be replaced, and if there are small cracks, they should be sealed with cement.

After the roof surface has dried, apply each subsequent one after the previous one has dried, and then apply paint. It is better to paint with a regular brush or spray, in three layers.

Since the roof, including slate, constantly absorbs any weather phenomena, and this is not only precipitation in the form of rain or snow, but also hard ultraviolet radiation, it must be reliably protected.

Previously used for these purposes Oil paint, which is why the positive effect was minimal and this coating lasted only a few seasons. Now, homeowners are offered a variety of solutions, with a wide range of colors, allowing you to protect slate for a period of five years or more.

The bulk of them are carried out acrylic or silicone based, such as organosilicon paint “KO-slate”, contains various fillers and dye. After drying, it forms a durable coating that is resistant to damage and also prevents the release of asbestos particles into the atmosphere.

One of the most famous is paint "Triora" on acrylic base , is applied in two or three layers, while it is possible to select a shade by tinting.

Tikkurila coating - based on a modified acrylate dispersion, this brand considered the most expensive, however, the resulting coating is capable of maintaining elasticity even at very low temperatures.

Slate can last long time and even if it is covered with moss and blackened, it can be painted, giving the building and the roof in particular, a completely new look.

The most ideal option would be to paint the slate sheets on the ground, followed by installation on top, but this is only possible if major renovation truss structures, in other cases, painting is carried out, being directly on the roof.

Slate should be cleaned of dirt by using metal brush, if necessary, rinse with a sprayer, pay special attention to the places where the nails pass, since if the fasteners are with homemade washers and without rubber gaskets, then quite a lot of debris and dust accumulates there.

You should carefully inspect the roof for cracks or holes, if any, the fragment will have to be replaced, and cracks are eliminated using cement plaster.

After preparing the surface, it needs to be primed in three layers with a special composition, applying the next layer after the previous one has dried. The paint is applied with a spray for a large roof area or with a wide square brush for small areas.

Before you ask yourself how to paint flat slate, it is advisable to find out what kind of material it is.

Slate is a facing layer for construction, roofing works. A common material is asbestos-cement flooring. It is available in flat and corrugated sheets. It has a drawback - a limited period of use. But if you paint it in time slate roof, then its service life increases.

Why paint slate

Painting slate with your own hands is done according to certain rules. Before you begin the process, you need to become familiar with the types of paints and roof preparation methods.

Building materials have positive and negative sides. Slate is no exception. Along with accessibility and ease of use, it has a number of disadvantages. Due to the presence of negative aspects, it is recommended to paint slate roofs.

The disadvantages include:

material porosity;
release of asbestos dust.

Dust, dirt, mold, moss, and fungi collect in the pores. They retain moisture, which under the influence of low temperatures turns into ice and destroys the material from the inside, deforming it.

Slate coverings are used as roofing material. The asbestos dust released by it is believed to affect human health. There are still no clear conclusions on this issue. Therefore, painting slate is an acceptable preventive measure.

Slate is destroyed under the influence of temperature changes. Its heating or cooling leads to wear and tear on the roof of the house. Paint minimizes risks and increases the service life of the roof.

Types of paints for slate

Before painting slate on the roof of a house, it is advisable to familiarize yourself with the types of paint coatings. Only after this do they decide what paint to paint the roof with.

First of all, the composition must be marked “for facades” (for work on the street). Otherwise, painting will not produce results; the coating will become unusable and begin to fall off in pieces. Secondly, the pigments must withstand direct sunlight, not fade, and the level of moisture resistance must protect the roof from getting wet and prevent deformation.

These include acrylic, alkyd, silicone paints and “liquid plastic”.

Acrylates

Acrylic paints are common compositions in construction. Some types are produced on water based. They are odorless, non-toxic, and dry in 1-2 hours. Coating with this material is done in 2-3 layers. The second type of paints, acrylates based on organic solvents (service life - 5 years). The disadvantage of this type is the presence of a pungent odor.

Alcide

Alkyd paints are made from organic solvents. These are fast-drying enamels that form an elastic film. The type of paint is resistant to moisture, has good performance adhesion, does not require preliminary priming and tolerates temperature changes. Service life up to 5 years.

Silicone

Silicone (silicon-containing) paint coatings, are a mixture of coloring pigments based on liquid silicone. They can mask cracks up to 2 mm in size.

Advantages of silicone paints:

moisture resistance;
camouflage ability;
elasticity;
antibacterial properties;
environmental friendliness;
no odor;
Possibility of painting without prior priming.

Silicone coatings are applied to dry surfaces.

Liquid plastic

The coating consists of polymers, pigments, and solvent. Drying on the surface, the paint forms thin layer plastics (polyurethane, vinyl, polystyrene). It is produced in both matte and glossy versions.

Characteristics:

moisture resistance;
fire resistance;
color fastness;
environmental friendliness;
resistance to sub-zero temperatures;
lack of interaction with chemical agents;
durability;
no pre-priming.

Mixed options are available on sale (for example, alkyd-polyurethane coatings). These compounds are very durable.

Color selection

Before you paint slate, you need to decide what color to paint it. Common type: paint red, green or brown flowers. For self-creation new shades are recommended to be used white paint and color. With its help you can easily achieve a certain color. On sale they correspond to the color catalogs RAL, NMS, Symphony.

On the color packaging, the manufacturer indicates the exact dilution proportions.

Preparatory work

After selection suitable type It is advisable to learn how to paint slate correctly so that you don’t have to redo it a year later. Regardless of whether it is painting flat slate or wave sheets, you need to approach the process competently and follow the necessary sequence of actions.

The old painted roof is carefully prepared. The roof can be cleaned manually (using an iron brush), using a medium-power mini-wash, or a combined method.

Cleaning the roof with a brush or drill with an appropriate attachment is done while wearing a respirator and safety glasses.

Previously, slate was considered the most popular material - more than half of the houses were covered with it. Today we can talk about serious competition - after all, manufacturers are constantly improving the quality and range of products they produce. roofing materials. However, the same slate is among the leading materials. He has positive characteristics over a long period of time. For example, low cost, good water and frost resistance, long term operation. These qualities are of course important, but not always relevant when choosing a material. After all, over time, slate acquires a gray-green color, and moss often forms on its northern side. In addition, ordinary factory-made slate may simply not fit into the interior of your home.

But if you have chosen slate, you will probably wonder how to paint a slate roof before.

Preparing slate for painting

For this procedure you will need the following materials and tools:

metal brush;
drill;
Bulgarian;
structures with high pressure jets of water;
antiseptic for construction;
brushes;
spray;
regular mask or respirator;
glasses;
gloves;
paint: acrylic and enamel;
primer.

Before painting, you need to thoroughly clean the slate. For example, if it has been in use for many years.

There are various methods you can use to clean your slate roof.

Note that the undoubted advantage of this method is that to clean a roof of 100 square meters, it will take you 1 or 2 days.

Treating slate before painting

The next step before painting the slate is the process of treating it with an antiseptic.

Considering that a damp environment is an ideal place for fungal spores, treat the slate with an anti-damp agent.

Note that old slate may have many pores - so it can quickly become unusable. Under these conditions, it is advisable to carry out hydrophobization to eliminate this kind of risk. Thanks to this, the service life of the material will significantly increase.

In order for the treated roof to look aesthetically pleasing, it needs to be painted. The best option– painting slate roofs before starting roofing work. But often many people ask this question only after several years. During this time, slate can seriously lose its aesthetic appearance and begin to decompose in the sun. Therefore, the stage of painting the roof is a very important component. In addition, this is the final stage in the work.

Inexperienced people may wonder how to paint a slate roof and whether it can be done at all? We answer: painting is a simple process. Paint is an additional protective layer. It is this that helps strengthen the slate structure from adverse influences. In addition, painted slate is not afraid of severe frosts.

Choosing paint for slate

It is very important to choose the right one - after all, this is the key to the beauty and quality of the future roof. Today you can find acrylic and enamel paints.

It is recommended to give preference to these types of paints, because they are specially designed to eliminate all microcracks on slate. Moreover, the painting film will protect the material from exposure to atmospheric agents. The paints contain binding components, thanks to which you can paint a slate roof. If your roof is in severe climatic zone– then it’s best to use quick-drying enamel.

Don't forget that you can always ask experts for advice or even entrust them with all the painting work of your slate. After reviewing photo and video materials on the Internet, you will have an idea about this type of work.

The quality depends entirely, in addition to the paint, also on the technology of its application.

This process can be divided into three components:

The slate surface is coated with a primer.
The slate is painted with the first layer of paint.
The second (final) coat of paint is applied.

How to paint a slate roof, details in the video:

Before painting slate, you need to consider the priming process. Any priming involves the use of deep penetration compounds. This will reliably strengthen the slate surfaces. You will notice that a primed roof is much easier to paint. The paint usually applies evenly to the primer, and its consumption will be significantly less than when painting without pre-treatment. It is recommended to use a primer consumption of about 100 or 150 grams per slate sheet.

The primer is most often applied using a sprayer, at an air temperature of +5 to +30 degrees. As a rule, the primer is completely dry within 12 hours. This is a temporary minimum - only after its expiration can it be implemented. For safety reasons, when working with soil solutions, it is necessary to use protection for hands (gloves) and eyes (goggles). Painting a slate roof involves proper preparation slate surfaces before painting.

After you have applied the primer, let the roof dry. Usually it dries all day, and the next day you can start painting it.

Slate painting: technology

When painting slate, remember that the first coat is the base coat. This is what usually consumes 2/3 of all paint and varnish material. After painting the first layer, check to see if there are any gaps, unpainted ends or corners. Carefully paint the areas that are most difficult to reach. After applying the first layer, you will see a completely different appearance of your roof. However, this is just the beginning - and there is no need to be lenient about the next layer.

Don't forget what to apply finishing layer It is possible only after the first layer has completely dried. The second layer will give the roof a certain uniformity. In addition, at the final stage you can remove the stains that remained after the first layer. The second layer involves the consumption of 1/3 of all the paint.

Required tools and materials

If you are tired of the color of the slate that has covered the roof of your house for many years, then everything can be fixed - we suggest coping with this problem by using paints and varnishes. So, let's find out what painting slate is and how to handle this process yourself.

Painting slate - what, how and why?

Let’s take as a starting point that you will have to personally tidy up the roof of the house, which means that you will have to become thoroughly familiar with such a rather important process as painting slate with your own hands – from “a” to “z”. If the slate on the roof of your house is in good condition, without cracks or damage, durable and does not allow water to pass through even heavy rain, then you can already begin work. But in order to put your roof in order for the next ten years and be confident in the final result of your work, you will still have to make considerable efforts. To do this, you will need to at least check, and if necessary, update the entire roof or part of it.

If your coating is completely leaky, then no amount of painting will help such a roof covered with cracks. Here you need to safely buy new slate, which will be the color you want. We will talk about work that concerns such a process as painting slate on a roof, but for the material that has been in use for more than one year. So, after one decade, or maybe more, your roof doesn’t look very good, and let’s say it’s completely unpresentable. Which means you need to get to work. As experts say, painting old slate is a completely doable job, but it is labor-intensive and not as easy as it seems at first glance. So, you will need, firstly, to find out about the real condition of the roof, and secondly, to decide on paint and varnish materials.

In order to avoid problems in the future, you need to choose the right material. And don’t listen to those who confidently say that after painting such a product, the paint layer will crack and crumble literally after the first cold weather. There are many examples when, after painting ( the right materials) painted slate has delighted its owners with its appearance for many years. So we make it a rule to choose paint accurately and comply with technological requirements when working. In addition, you should consider what kind of slate you have - wavy or flat. It depends on this what is better to paint - paint roller or with a brush. If you already use the material (installed on the roof), then you will have to stock up not only with patience, but also with a ladder (preferably very stable, since the work will not take an hour or two). If you are going to paint the product on land, then prepare a special elevation for convenience (so that the product does not crack or get dirty).

Painting slate - what is the best way to paint it?

The choice of paint, as well as slate, is quite large - the paint can be from both domestic and foreign manufacturers. Naturally, the price also varies - depending on who the manufacturer is and on what basis (silicone or acrylic) the paint is made. For example, silicone paint, which is silicone-based along with fillers, allows this mixture to form a super-strong and durable coating. And most importantly, in addition to a purely decorative function, it allows you to prevent asbestos particles from escaping into the atmosphere (remember that in Europe some components of asbestos slate are considered hazardous to health). This paint is applied only to the surface that has been previously treated with silicone primer. It is not compatible with other types of coatings.

Professionals advise that in order to achieve the result you want, apply paint in two layers.

If you take slate paint with an acrylic base, it will also have excellent performance qualities. Like silicone, it is applied in two layers, and also on a previously prepared surface. If the product previously had old coatings - for example, silicone or oil - then they must be removed, and completely. This paint is slightly cheaper than silicone, has excellent light fastness and is resistant to moisture. It is also convenient that it can be tinted, choosing the shade you need.

You can also choose a special coating in the form of paint based on a modified acrylate dispersion. Of course, it costs a lot, but, as experts note, its cost is justified high quality coverings. A layer of such paint, as practice shows, remains elastic even at particularly low temperatures. Paint is also applied only after preliminary treatment of the entire surface. Among the manufacturers there are also many representatives from other countries. The main thing is that you choose not only by price, but also by quality, and when choosing paint, remember that it should be intended specifically for slate.

How to do everything yourself

When starting work, remember that you must strictly adhere to all rules and regulations, otherwise your painted slate will again need serious repairs in a short time.

How to paint slate with your own hands - step-by-step diagram

Step 1: Check the surface

For high-quality painting, it is necessary to carefully prepare the slate surface. This process is carried out in several stages. If this is an old coating that has been in use for many years, then you should start with a “meticulous” inspection. Pay special attention to the coating - you may find moss on it. It will need to be removed before painting.

Step 2: Prepare the area for work

Some experts recommend clearing vegetation from your roof using a drill and brush. The main thing with this approach is not to accidentally damage the sheets themselves. Once you have dealt with the moss, you need to check if there are any breaks or cracks on your roof. If they do exist, we seal them with a mixture that can be made from PVA (diluted with water), cement and asbestos. We have resolved the issue with cracks and defects - we begin to remove debris and dust. Only an absolutely clean surface will allow you to achieve the desired result when painting.

Step 3: Wash the coating surface

In order to wash the slate surface, we use household brushes and water. Just do not forget that after such water procedures the slate must dry thoroughly. Don’t try to do everything quickly and “just how.” Better slowly, but efficiently!

Step 4: Working with Primer

Further work with the coating involves a primer. We treat the slate coating with a special compound in order to increase the “adhesion” of the materials. This process will also help to achieve the necessary contact between the slate paint and the top coat. By the way, asbestos cement roofing absorbs any materials quite well, and if you treat the surface poorly, you risk encountering stains after painting that will stand out strongly.

Step 5: Paint the roof

If you do everything correctly, then it is better to start painting in cloudy rather than sunny weather, and the air temperature should be about plus 15 degrees. At temperatures above 35 and below 0, you will simply face the impossibility of your mission. However, some manufacturers assure that their brainchild can be used at fairly low temperatures.

There are two methods of applying paint - manually or using a sprayer. You have the right to choose as you wish. Either one or the second option will be effective. Just keep in mind that the paint consumption indicated by the manufacturer often does not correspond to reality. So, you have applied the first layer - now you need to let it dry thoroughly. Your paint package will indicate how long to wait before applying the second coat. But keep in mind that it is better to give the roof more time than indicated by the manufacturer (optimal conditions are indicated on the container).

Step 6: Finish painting

If you have had high-quality primer, then a second coat will be enough to get an even color and coverage. If you still have doubts or the result does not satisfy you, it is better to resort to a third attempt. The final layer is considered to be the one after which you get a uniform color coating. And do not forget that the paint will completely harden only after a few days.

What paint is better to paint slate 👷 on the roof of a private house with your own hands, advice from craftsmen

There is a huge selection of roofing materials on the modern construction market, but despite this, ordinary gray slate has not lost its popularity. This is explained by its good performance, resistance to temperature fluctuations in the external environment, long service life and low price.

Houses covered with slate in the last century faithfully serve their owners to this day, but the surface of the roof, while maintaining its performance characteristics, has an unsightly appearance. Slate staining helps correct the situation. Painting slate with your own hands is quite possible, you just need to know how to do it correctly.

Perhaps painting slate is an interesting and even enjoyable activity

Why do people paint old slate?

Painting slate allows you to get rid of these negative phenomena. People paint old slate the following reasons:

the release of fine asbestos particles harmful to health into the environment is reduced;
waterproofing qualities are improved;
resistance to temperature fluctuations in the external environment increases;
the operating period is significantly increased;
the development of pathogenic microflora is prevented;
the painted surface has high decorative properties.

The painted roof harmonizes well with the color of the walls

Of course, it is simpler and easier to paint at the stage of installing the roofing. In this case, the slate can be painted on the surface of the ground and then installed in its place.

However, it often happens that owners of private houses think about performing this procedure after several years of operation, when the surface, green with moss, absorbs moisture and creates an increased load on the rafter system. At the same time, green paint is very popular.

Preparing for painting is an important and considerable job.

Before starting work, the surface must be thoroughly cleaned. Most in a simple way performing this manipulation, which does not require the use special tools, is mechanical cleaning with a wire brush.

It is very convenient to clean slate with a high pressure car wash.

Work should be done in dry weather, as the mechanical strength of a wet coating is reduced. Cleaning in this way requires a lot of time and physical effort. A grinder or a drill with a brush installed on it allows you to reduce the physical effort required to complete this work, but it requires the right eye and steady hand in order not to damage the coating.

The fastest and most effective way to clean a surface is with a jet of water supplied under high pressure. Such devices are used for washing vehicles. The optimal pressure will be from two hundred to two hundred and fifty atmospheres; with a lower value, it will not be possible to effectively remove contaminants; with a higher value, a directed water jet will break the coating.

When performing all manipulations, you should use personal respiratory and eye protection, as asbestos dust will rise into the air. You need to work in a suit made of thick fabric, a respirator and goggles.

What paint and primer is best to paint the roof of a house?

Before you start painting the slate surface with your own hands, it must be impregnated with a special composition that prevents the development of pathogenic microflora. Apply it with a wide brush, paint roller or spray. To ensure quality protection antiseptic treatment performed in several layers.

There are special primers for slate

Then a composition is applied to the coating that prevents the penetration of moisture. Due to the porous structure of slate, its premature destruction occurs precisely from the aggressive effects of water. After antiseptic and moisture-repellent treatment, a layer of primer is applied. It provides high-quality adhesion of the paint to the base and reduces its consumption. The primer should be purchased from the company that produced the main paint material, and it should contain components that prevent the development of pathogenic microflora.

Used for dyeing paint material must be well resistant to aggressive environmental influences, heating by direct sunlight, and have water-repellent properties. Acrylic and alkyd paints, polymer and silicone based coatings. We'll figure it out a little later which one is better.

Painting is performed in two layers, the first of which is the main one. You can apply the paint with a paint roller, a wide brush or a spray gun. Of course, painting the slate surface is carried out in dry, windless weather.

Acrylic paints

The most widely used are water-soluble acrylic compositions. They do not emit a strong odor or toxic substances due to their water base, do not ignite when exposed to an open flame, do not require the use of solvents and form a waterproof coating with a service life of about five years. Acrylic paint applied to the surface dries within sixty minutes. The disadvantage is that it has a liquid consistency and streaks may form on the coating.

Silicone based coatings

Silicone-based coatings are considered the most reliable and durable. Due to their high elasticity, they are able to fill fairly deep cavities; they can be used without applying a primer layer. The silicone surface has a high mechanical strength, excellent properties to repel dirt and moisture.

By filling the slate pores well, it prevents the development of pathogenic microflora in them. The material does not support the combustion process and does not emit harmful substances and unpleasant odor into the environment. The service life of the coating is about fifteen years.

Alkyd paints

Alkyd paints are different short time drying, while forming an elastic surface that is not subject to cracking. They have excellent adhesion to the slate surface and are highly resistant to aggressive influences. environment and atmospheric moisture, do not require mandatory priming of the base before application. Average term service is about five years.

Polymer-based coatings

Polymer-based coatings, which include vinyl, polyurethane or polystyrene, form a glossy or matte plastic layer when applied. It completely blocks the penetration of moisture to the slate surface, is inert to chemicals, and does not fade from ultraviolet radiation, does not support combustion and is environmentally safe.

Choosing color and shade

The most common colors for roofing surfaces are green, brown and red. However, the color palette offered by manufacturers of this type of product can consist of more than a hundred colors and shades. Do-it-yourself green slate roofs are very common.

What to do if you want to paint the surface non-standard color, which is not in the company's catalogue? Which color to choose? The right shade can be created by adding tinting paste to the paint and stirring it well. Most companies provide the possibility of tinting, that is, obtaining any tones color palette. When choosing a color, you need to take into account the surrounding environment, while green roof gets lost in the dense garden.

When finishing a slate roof with your own hands, you should listen to the advice of craftsmen. To feel safe when working at height, you should use a safety belt. Cleaning, priming and painting the surface must be carried out in a protective suit, goggles and a respirator.

If you don't have a spray bottle, painting slate with a flat surface should be done with a paint roller rather than a wide brush. For the first layer to dry, you need to leave more time than indicated in the instructions, most often they consider ideal conditions, different from reality.

You can paint slate before installation or directly on the roof using a brush or spray gun.

Before carrying out work, you need to familiarize yourself with the weather forecast for several days in advance: the coating will last longer if it does not rain after the final stage. On the steep gable roof It is better to work together with an assistant. A high-quality painted roof surface will delight owners with its appearance for many years; the coating will not peel off or crack over time.

The following video has been carefully selected and will certainly help you understand what is presented.

How to paint slate to improve its appearance?

In the old days, more than half of private houses in Russia had slate roofs. It retained its hegemony for a long time until the construction market opened up to new materials with a more impressive appearance, a variety of installation methods and better performance characteristics. Now the share of slate roofs has decreased significantly, however, experienced builders advise not to discard this practical material out of the question, because in terms of cheapness, durability and reliability it gives a head start to the most modern species roofs. The only problem that forces us to abandon this finishing option is its inexpressive appearance. Fortunately, there is a simple and inexpensive solution - painting the slate with a special composition.

Coloring tasks

Flat and wavy slate- a fairly common roofing material, the gray color of which becomes boring to homeowners over time. Experienced craftsmen They don’t see any reason to refuse installation if the reason is only an inexpressive color, because slate paint can easily solve this problem. It is worth painting a slate roof because:

The paint layer is an additional binder for asbestos dust, which is considered harmful to human health. With its help, you can make slate a safer material for finishing roofs and facades.
When applied, slate paint fills microcracks and pores on the slate surface, enhancing the waterproofing of roof coverings.
Painting slate solves the problem of roof slopes becoming overgrown with moss, which is faced by everyone who decides to have a slate roof. With its help, you can eliminate the fungus and pests that live on the porous surface of this material.

Important! Best time to give color to the roof, which was covered with flat or corrugated slate, desired color- before the beginning installation work. However, such real life happens extremely rarely. More often, homeowners think about how to improve or update their roof 5-7 years after construction.

Preparing for coloring

The preparatory stage of staining is perhaps the most important in the entire process. The durability and quality of the coating depends on how the surface is prepared. Therefore, slate preparation must be treated with care, carefully following the technology. Before painting slate, if it is in use, you need to take care of cleaning its surface. This task can be accomplished in three ways:

Clean the slate roof with a wire brush. To remove dust, dirt, and moss from the surface, work thoroughly with your hands, removing all excess. These manipulations will be performed only in dry weather, so as not to damage the roof, which becomes more fragile when wet. This method of surface preparation takes a lot of time and effort, but the good thing is that it does not require special tools.

Important! All slate cleaning work is carried out in protective gear, since the asbestos dust released during the process is dangerous for the respiratory tract and mucous membranes. Be sure to use wet respirators, protective eye masks and protective clothing. To reduce dust, you can moisten with water from a spray bottle and work outdoors.

Protective covering

First of all, the slate surface is treated with an antiseptic composition. deep penetration. They are necessary to stop the expansion of fungus and pests. The treatment is carried out with a wide brush, roller or sprayer. If necessary, several layers of antiseptic are applied to the slate to provide better protection. After completing the work, the composition is given time to absorb and dry.
The next step to protect the roof is applying a water-repellent compound. The fact is that for the porous structure of slate there is no more dangerous enemy than moisture. This is the most likely cause of premature deterioration of the roofing material.
After the antiseptic and moisture-repellent coating has dried, a primer is applied to the flat or corrugated slate. A deeply penetrating primer levels the surface, smoothes out roughness, and fills microcracks. With the help of a primer, painting slate yourself is easier, the paint goes on more evenly and is consumed more slowly.

Note! Painting slate with your own hands, starting with high-quality surface preparation, gives an unsurpassed result. Activities for cleaning, disinfecting and priming the roof will make the coating rich, uniform and durable. During the application process, do not forget to process the cuts and edges of the material.

Paints used

Will DIY slate paint be beneficial? roofing, depends on the correct choice of composition. Experienced craftsmen advise using paint and varnish products that are resistant to temperature changes, moisture and ultraviolet rays. Most good options can be called:

average consumption

square meter

Important! To obtain a durable coating, work on its application is carried out in the warm season, at a temperature of +5 - +20 degrees, in dry weather. The main condition for the quality of painting is compliance with the drying time and the recommended number of paint layers.

With a little effort, with minimal financial investments you can turn a gray, dull roof into architectural masterpiece. The right color and staining of slate works wonders, making it an ideal material for blood.

Should a slate roof be painted?

Many old private houses have slate roofs. This one is long ago famous material has a number of disadvantages and, if you choose what to make a roof from now, it will lose in the competition to many modern materials.

Slate roof painting

Is it worth rushing to re-roof if it has lost its presentable appearance, is covered in places with moss, but is regularly fulfilling its main duties, protecting the house from precipitation and temperature changes?

It is far from necessary to do this, and if the slate is given a beautiful appearance, it will last for another ten years, thus saving money for more urgent needs. Thanks to modern materials, this can be done by painting it. The most commonly used are silicone or acrylic paints designed specifically for this type of work. Such paints form a durable and stable coating, which additionally has the function of protecting against the harmful effects of asbestos contained in slate. In order for the coating to serve for a long time without peeling, it is necessary to fully comply with all technological nuances specified in the instructions for use.

Preparing slate for painting is carried out in the following order.

First, places of pollution (both natural and man-made) and areas where moss colonies have formed are identified (most often this is the northern slope of the roof). You can clean them with a regular metal brush, but it is more convenient to use a brush attachment for an electric drill.

Next, cracks and breaks that have arisen during long-term operation are sealed. To do this, you can use a mixture of PVA glue, finely grated asbestos (a regular grater will do) and cement.

After the restored areas have dried, the roof is swept using a regular broom or brush. To ensure that dust and impurities invisible to the eye are cleaned as efficiently as possible, the slate is washed, preferably using detergents, rinsed and dried.

Further, to increase durability, the slate is processed antifungal drug and primed. The primer not only increases the service life of the painted product, but also reduces paint consumption while ensuring uniformity color range Therefore, it should be carried out with particular care.

The final stage is the paint application process, which is carried out in two layers, preferably under optimal thermal conditions. The most optimal temperature is 10-20 degrees, although paint manufacturers talk about a wider range of applications. You should also avoid direct sun rays during the dyeing and drying period.

Do you want to update your roof? country house? In this case, you need to find out what you can use to paint flat slate in order to carry out the work as efficiently as possible. The main thing is to choose the right material for painting!

Very often you can hear that painting a roof is very short-lived, they say, the paint will crumble after just one winter, and in general it is better not to mess with such a thing - as it is, so it is. Of course, this can happen, but only if you approach the purchase of colorful materials thoughtlessly. That is why we will now discuss which paint to choose if you decide to update the appearance of your roof.

Most often, solutions are represented by silicone or acrylic-based compounds; there is also such a product as liquid plastic. But more details about everything:

Acrylic paints. They have the following advantages: non-toxic, dry quickly, provide a high level of adhesion, wear-resistant, create a smooth surface. Acrylic compounds fill small cracks, covering the roof with a sufficiently durable layer that protects the material from destruction. The roof begins to repel moisture, and water and snow disappear from such a roof much faster. The main thing is to follow all the manufacturer’s recommendations, which are indicated on the packaging, otherwise the paint will quickly peel off.
Bitumen-based compositions. They are characterized by such advantages as moisture and frost resistance, low cost. But there are also disadvantages: toxic, wear out quickly, do not have aesthetic properties, long drying time.
Liquid plastic. Polymer enamel is characterized by stability and practicality, forms a beautiful smooth film on the roof, is quite cheap, and dries within half an hour. But in terms of frost resistance, liquid plastic is inferior to acrylic compounds.
Silicone based paints. They have advantages: they can extend the life of the roof, resist precipitation, non-toxic. The disadvantages include high cost and high paint consumption.
Oil enamels for slate. I am pleased with the wide selection of shades and durability. But the disadvantages include a long drying time (about 6 hours), service life - about three years.
Organosilicon paint for slate, which is a mixture of several dyes and fillers. The basis of such compositions is silicone. Main characteristics of the material: strength, resistance to mechanical stress. This coating will not only perform a decorative role, refreshing the roof, it will also prevent the release of asbestos elements into the air. This type of solution is incompatible with other types of coatings; it should be applied to the roof only after it has been thoroughly treated with a silicone primer. To make the coating durable, paint is applied in at least two layers.

Whatever paint you use, in any case you need to remember that the mixture must be purchased directly for slate. Only in this case will it last a long time without losing its original color and properties. Knowing what to paint with, you can move on to the second step - preparing the surface for painting.

As we have already said, before applying paint, the slate surface should be prepared for painting. In this case, the preparation is divided into several stages, each of which should be carried out as efficiently as possible. Otherwise, it is not a fact that the paint will last for several years.

Roof preparation stages:

First of all, you need to carefully inspect the entire roof and remove the moss that grows on the north side. To do this, you can use a drill with a brush or a regular metal brush, although it will be much heavier, but a power tool will make the work much easier. Only in this case should you act very carefully so as not to damage the slate in any way.
Also check the integrity of the roof. If there are breaks or cracks, be sure to seal them using a special mixture, which is prepared from materials such as cement diluted with water, fluffed asbestos.
The next step is removing debris and carrying out a procedure such as dust removal from the roof. These works can be carried out using water and brushes. After completing the procedures, allow the roof surface to dry. If you have any car washer available, you can use it - this will reduce the cleaning time. The surface should also be treated with a special antifungal agent, which will increase the service life of the slate.
An important stage in the preparation of slate is its coating with primers. It is this stage that will increase the level of adhesion of the material, ensuring good adhesion of the paint compositions to the coating. If the treatment is carried out poorly, it threatens to quickly peel off the paint.. In addition, purchasing a primer will allow you to reduce the amount of paint you use, which is especially important if you are going to use expensive options.

Before starting work, you need to familiarize yourself with several basic rules for performing work. First of all, it is advisable to carry out painting in cloudy weather, when the air temperature does not exceed 15-18 °C. These conditions are necessary for the paint to be applied and dry properly, forming a practical coating. By the way, many people are interested in whether it is possible to paint slate at zero temperatures.

Despite the fact that many manufacturers guarantee this possibility, it is better not to risk expensive paints in vain.

There are several methods for painting slate. The first, and also the easiest, is to use a spray bottle. It is very important to take into account one point: you should not expect that the specified amount of paint consumption on the spray container will be correct. Most likely, you will have to spend a lot more material, so when purchasing paint, take this point into account. After applying the first coat of paint to the prepared surface, let it dry. The drying period differs different compositions– all information about the paint is located on the packaging.

However, even in this case, try to leave the paint on the slate a little longer than what is written in the instructions to be sure that it has dried. After all, the information provided most often applies to ideal conditions for painting, which are difficult to achieve in practice. After this, apply a second layer and also wait until it dries. If you have primed your roof, two coats of paint will be enough to create a durable coating.

The coating will gain maximum strength in about a few days. Therefore, try to choose non-rainy days for painting, otherwise all your work will be in vain. Now you know what you can use to paint flat slate and how the work is carried out, which means it’s time to start updating the roof. The second method is also simple, but requires more effort and time. To do this you will need a paint roller. However, it is immediately worth noting that working with such a tool is difficult and dangerous, because flat slate will be painted at a high level, which means you should be as careful as possible.
