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 term service 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 activityWhy do people paint old slate?
Painting slate allows you to get rid of these negative phenomena. People paint old slate for 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.
An important stage in the work is preparing the surface for painting. The long service life and high performance qualities of the finishing coating ultimately depend on this. All technological details of the dyeing process must be observed.
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 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 surface is cleaned most quickly and effectively with a stream 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 efficiently 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 a spray bottle. 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 ensures 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.
The paint and varnish material used for painting must be well resistant to aggressive environmental influences, direct heating sun rays, have water-repellent properties. Acrylic and alkyd paints, polymer and silicone based coatings have these qualities. 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 pungent odor or toxic substances, thanks to water based, 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.
Paint options for slate 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 bad smell 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.
Polymer-based coatings resist exposure well negative temperatures, application is possible without mandatory priming. The period of operation is about fifteen years.
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.
Green roofing is very popular 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 of the 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.

Painting the slate on the roof will make the covering look attractive and protect it from the external environment. Today you will learn how to paint slate on a roof and how to do it correctly.
In the video in this article you can see a lot useful information and do quality work.
Why paint slate?
For a long period of time, slate has been one of the most popular materials for roofs of houses and buildings. Such fame is easily explained by its affordable pricing policy and long service life.
Today, flat slate, like wave slate, is often used in construction various structures. But like everyone building material, it has not only advantages, but also a number of disadvantages.
For example:
- Slate does not have an aesthetic appearance, which does not allow it to be classified as decorative or luxury building materials. It is destroyed in an aggressive external environment. Under the influence of moisture it can become overgrown with lichens or mosses.
- As a rule, timely painting of the roof helps to cope with a number of such problems. This type of application of coloring compositions can be done with your own hands. The layer that is formed during painting protects asbestos cement from the effects of wind, preventing it from weathering, and does not allow it to undergo biological destruction.
- In order for the service life of such a roof to be longer, it is necessary to treat the slate roof with special protective solutions, and only after that with paint. But, in fact, such measures can be carried out not only when the slate is new, but also when it has already acquired a black color and the process of its destruction begins.
- In order to protect roof covering and prepare for painting, the following activities should be carried out:
- removing moss and lichens from the roof.
- Cleaning it from dirt and dust particles.
- Treatment with antiseptic compounds and water repellent.
- Roofing primer.
- Painting it twice with drying between layers of paint and varnish products
- If the slate is prepared correctly, then paint coating lays down in an even layer, does not chip, does not lag behind, which protects from external environmental influences, but also gives a presentable appearance to the building.
Attention: Painting a slate roof will eliminate a number of shortcomings.
Rules for performing roof painting work
How to paint slate roof Now let's look at it in detail. If you do everything yourself, then the cost of the work will not be significant.
Roof cleaning
Before deciding how to paint a slate roof, you need to understand the principle of coating. After all, technology is important here, otherwise the coating will not stick.
So:
- If asbestos cement has been lying on the roof for many seasons, it is best not only to sweep the material away from debris and wipe it, but also to remove the moss and lichen that have grown on it. Most often they spread on roof slopes.
- A stiff brush will help deal with build-up, but treatment should be carried out exclusively on a dry roof surface. Of course, you can clean it by hand, but an angle grinder with an attachment in the form of a stiff wire brush will help optimize the process. You can purchase it at any hardware store.
- If you use a power tool in your work, it will make your work easier, increase the speed and improve the quality of cleaning the roofing material. After all the slopes have been cleaned, the coating on top must be brushed with a regular brush and then rinsed warm water and allow to dry before proceeding to the next step.
- Those places that are difficult to reach and cannot be cleaned are manually scrubbed using a grinder with a stiff brush, extremely carefully so as not to damage the coating.
- You can clean slate using a high-pressure water jet. This method can only be used if there is special equipment. With this cleaning method, the procedure can be carried out in any weather, regardless of precipitation, the main thing is that the air temperature is positive.
- Before cleaning, the pressure should be selected correctly; it should not exceed more than 250 atmospheres. If it is higher, it can negatively affect the slate and lead to destruction. But it is worth considering that the water pressure should not be weak, otherwise it simply will not eliminate moss and lichens on the roof.
Slate roof treatment
Before coating asbestos-cement material with paints and varnishes, it is necessary to carry out a number of procedures that will increase its resistance to an aggressive external environment.

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 roofing materials they produce. 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 service life. 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 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 water jets;
- 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 the roof in 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 works. 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 the 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 slate roof, details in the video:
Before painting slate, you need to consider the priming process. Any priming involves the use of compounds with deep penetration. 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 your 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.
How much slate do you need for the roof?
-
Many people want to update the look of the roof of their home. Thanks to modern technologies It's not that hard to do. The most common procedure – painting with special compounds – allows you to transform the dull appearance of gray asbestos cement sheets into a bright, beautiful and unusual one.
For a long time, slate was completely self-sufficient roofing material, which has proven its reliability for decades. However, if you remember his unattractive gray, then the question of whether it is possible to paint it has not lost its relevance all this time. Decoration is just one aspect.
Painting solves purely protective problems in practice. Paint protects the roof surface from destructive atmospheric influences; it helps reduce water absorption and increase frost resistance. That is, it can be argued that depending on what paint you use to paint the slate, you can significantly increase the service life of the asbestos-cement roof.
Is it possible to paint and with what?
You can often hear that paint for flat slate It is very short-lived - one winter is enough and it will crumble. Undoubtedly, this cannot be ruled out, but only for those cases when it is chosen incorrectly. Let's try to figure out what and what paint is best to paint with.
Types of paint
Typically, asbestos is painted with one of the following materials:
- containing acrylic;
- quick-drying;
- liquid plastic.
The last of them is perhaps the least suitable for asbestos-cement roofing. Unlike the other two, it is less weather-resistant, and also has a rather pungent, unpleasant odor.
Enamel with a quick-drying composition gives the roof an exceptional decorative effect. This finish is resistant to weather conditions and UV radiation. The consumption of this material is 100–150 g per square meter. m. The performance characteristics of the coating are maintained for 3–5 years.
It is no coincidence that acrylic compounds are used predominantly for painting ACL. It is considered the most durable and safe of the above. After applying the composition, a moisture-proof film is formed on the roof surface, which, if properly applied, does not collapse for at least ten years. Acrylic coatings create a smooth surface along which rain and melt water flows freely and snow melts, reducing the load on load-bearing structure roofs.
The latter is very important, given the significant load from the asbestos-cement sheets themselves.
It takes more acrylic than a quick-drying composition to cover a unit area - about 0.3 kg per square meter. m. Acrylic compositions
- environmentally friendly,
- do not have harmful secretions,
- wear-resistant,
- dry quickly,
- provide increased adhesion.
- completely fill all cracks, and the resulting sufficiently strong layer effectively protects the material from destruction.
When applying paint to the roof, you must strictly adhere to the manufacturer's recommendations - they are usually marked on the packaging.
The list of materials is much wider.
- Bitumen compositions are moisture- and frost-resistant and have an affordable price. However, they are toxic, wear out easily, are not aesthetically pleasing, and require a long time to dry.
- Silicone compounds extend the service life of the roof, are non-toxic, resistant to atmospheric influences, but are quite expensive and this comes with significant paint consumption.
- Special oil enamels are distinguished by a wide variety of shades and durability. They take quite a long time to dry, about six hours, and their service life is about three years, which is undoubtedly not very long.
- Organosilicon paint is a mixture of dyes and fillers. The basic component of this composition is silicone. This durable material, resistant to mechanical loads. Such a protective layer prevents the release of asbestos particles into the atmosphere. Such compositions are only suitable for this type of coating and require careful treatment of the base using a silicone primer. To give greater durability, the paint is applied in at least two layers.
Stages of painting an asbestos cement roof
Before painting the coating, quite labor-intensive preparation is carried out. First of all, each of the sheets is checked for integrity and reliability of their fixation.
Sheets that show cracks or damage must be replaced.
The next step is to carefully clean the roof of any dirt, moss, etc. Asbestos-cement sheets are cleaned of old deposits using sandpaper and treated acrylic primer containing a special antifungal component. As a result of the primer, the pores of the roofing material are filled.
After the primer has dried, apply to asbestos-cement sheets cement mortar. The consistency should resemble kefir. A brush is used to apply the solution. Other tools, say a roller, are not suitable for this.
Dove cement mixture completely dry, the roof is primed, after which the roof is painted.
When is the best time to do the work?
Is it possible to paint in wet weather, when is the best time to paint? Questions that concern many, especially those who intend to handle the roof themselves. Painting of ACL must be carried out in the dry, warm season.
The paint is applied in two layers using ordinary painting tools, for example, a spray gun. The second layer is applied to the completely dry first one. Practical experience shows that painting in the spring provides them with long-lasting protection, gives the roof a decorative appearance, and prevents the appearance of moss.
Standard gray slate does not attract attention at all with its appearance. However, by painting it in certain colors that match your exterior, you can radically change your opinion about this material. Slate paint must have certain properties, including, first of all, its resistance to moisture and color change. Let's look at how to choose the right paint for slate below.
Features and scope of use of slate
Slate is a fairly popular material for roofing. In addition, with its help it is possible to build fences for the site and even small outbuildings. For making wave slate asbestos cement is used. With the help of special fibers, the mechanical resistance of slate is increased.
Slate sheets have a standard gray color. However, you can paint this material in almost any color or shade. This will improve not only his attractiveness, but performance characteristics.
In order to learn more about this material, we suggest that you familiarize yourself with its advantages and disadvantages. Let's start with the advantages:
- a successful combination of cement and asbestos significantly improves the strength of the slate covering;
- this roofing option heats up less from the sun than metal;
- the material is not susceptible to rust, has excellent moisture resistance and does not conduct electricity;
- during combustion the material does not emit toxic substances;
- slate has a long service life;
- the cost of such material is much lower than that of alternative roofing made of metal or corrugated sheets;
- slate is an excellent sound insulator - during heavy rain there is no noise inside the house.
Among the disadvantages of slate we note:
- slate is quite fragile and can be easily damaged during transportation;
- The total weight of one sheet is about 18 kg, so at least two people will be required to lift it onto the roof.
In the process of exposure of slate to moisture and changes temperature regime, over time it begins to become covered with asbestos crumbs, resulting in the formation of microcracks and moss, which reduces its attractiveness.
In order to prevent this unpleasant factor, it is recommended to paint the slate. Paint will provide additional protection material from moisture, moss formation, and also increase the attractiveness appearance slate covering. Modern paints also contain antiseptic substances that prevent the development of mold and mildew. With their help, biological protection of the roofing is provided.
When planning a replacement old decoration If you are installing a new slate roof, we recommend that you initially think about painting it. At the same time, it is recommended to carry out this work before installing slate on the roof.
Slate paint - features of choice and characteristics
In relation to the main active ingredient of slate paint, they are:
1. Acrylic or water-dispersion - this type of paint is applied to the slate surface previously coated with a primer. Acrylic paint for slate protects it from moisture and destruction, improves its sliding characteristics, thanks to which precipitation flows down the roof more easily. Paints on acrylic base dry quickly and have a variety of color palette.
2. Paint for painting slate on an enamel basis - it is characterized by a high content of binders in its composition, has moisture-proof properties, and is resistant to precipitation. The coating, after painting, acquires additional strength characteristics. The pigments contained in the paint protect the coating from fading.
3. Roofing paint on slate in the form of liquid plastic is synthetic material having a bitumen, polystyrene or polyvinyl chloride base. These paints are affordable, however, compared to acrylic paints, this material has lower moisture-proof properties. In addition, such paints often contain substances harmful to human health.
4. Rubber slate paint is a fairly popular material for painting roofs. Among the advantages of rubber-based paint, we note:
- high elasticity properties, when small cracks appear on the surface, the paint stretches without damage;
- The paint does not contain substances harmful to human health, it is non-flammable and differs high level fire safety;
- provides slip protection, especially important when installing a flat roof;
- is highly resistant to wear and can last on the coating for many years;
- improves the performance qualities of slate - it is resistant to external irritants, fungus, corrosion and wetting;
- It is universal in use and has a varied color palette, so it will suit any exterior.
Using rubber paint to finish slate extends its service life several times. Slate becomes pleasant and attractive in texture. In addition, the paint perfectly waterproofs microcracks in slate. To ensure durability of the coating, it is recommended to apply rubber-based paint in at least two layers. It only takes a few hours for the paint to dry.
In relation to slate paint manufacturers, we note:
1. DachbeSchichtung - paint of German origin, has a high cost, which fully justifies its performance characteristics. The paint also has high adhesive properties, good strength, and long service life. However, this paint is suitable for coating natural tiles or slate.
2. Polyfarb - Polish dispersion-based paint, dries quickly and has a rich color palette. The paint has good resistance to moisture and ultraviolet radiation.
3. Aqua - Finnish-Swedish paint, dissolves with water, is resistant to aggressive alkaline environments. It is used not only for painting the code, but also for applying it to a concrete base.
Tikurila paint for slate: features of use and characteristics
“Tikkulira” offers paint for slate “KILPI”. It is an acrylate-based coating, diluted with water, which allows you to paint not only slate, but also bitumen roofing or concrete tiles.
With the help of this paint it is possible to significantly extend the service life of slate. In addition, it is highly resistant to solar radiation, moisture and other atmospheric influences.
Acrylate-based paint reduces the impact of moisture on slate coverings, making it possible to maintain its original appearance for many years. The paint contains special components that prevent the development of mold and mildew. The coloring composition does not lose its elasticity at both high and low temperatures.
Using Tikkurila slate paint, you can create a beautiful matte finish that resists the accumulation of dirt and dust. There are many colors for painting slate that will harmoniously match any exterior.
Is slate painted with paint: features of applying rubber paint
Before you start coating slate with rubber paint, you should prepare the surface. If there is dirt, grease stains, or dust on the slate, they must be removed. Since slate is a porous surface, it is necessary to coat it with several layers of primer. Thus, it will be possible to reduce paint consumption.
Use white spirit to degrease the surface. If the slate has already been painted, try to remove the paint. To apply paint, the air temperature should be from 15 to 30 degrees Celsius. At the same time, the maximum humidity permissible for performing work is 75%.
Before starting work, read the instructions for use of the paint composition. Next, open the container and mix the paint. Please note that diluting paint with drying oil or any other thinner is unacceptable.
If the paint has a high viscosity, then it is possible to add superprimer 100 to it, and then in a very small amount. To mix the paint, use a drill with a mixing attachment or a construction mixer.
To apply paint to the slate surface, a roller or pneumatic spray is used, in which case the surface is covered in several layers. While working, stir the paint periodically.
Features of choosing paint for flat slate
When asking what paint to paint the slate on the roof with, you must first decide on the type of slate used to finish the roof. Most often it is wave or flat slate. The following types of coloring compositions are suitable for one option or another:
1. Acrylic-based paints are environmentally friendly, dry quickly, adhere well to the coating, and also help create a smooth surface. Using this material you can quickly and easily paint any type of slate. The main rule for the high-quality operation of such a coating is compliance with all conditions from the manufacturer for applying the coloring composition.
2. Bitumen paint compositions are less popular due to their toxicity, although they are affordable.
3. Liquid plastic forms slate on the surface protective coating, which significantly improves the service life of slate.
4. Among the main advantages of silicone-based paints, we note:
- absolute harmlessness;
- long-term operation;
- good adhesion with slate.
At the same time, such compositions are quite expensive and have high consumption.
5. Enamels on oil based also used in the process of staining slate. They do not lose color over many years of use, they have quite rich and bright shades, but they take a long time to dry, approximately 5 hours.
6. Silicone-based slate paint - consists of silicone with the addition of dyes and various kinds flooring substances. The material is quite durable and resistant to mechanical substances.
It’s up to you to decide which slate paint is best, but remember that in the process of choosing paint, you need to take into account the individual characteristics of the work.
How to paint slate yourself
Before starting work, you should prepare the surface for painting. If the slate has not yet been laid on the roof, then paint it before starting. installation work. If you do not follow the recommendations for preparing the surface for painting, the service life of the paint will be significantly reduced.
Before you start painting works, follow these steps:
- thoroughly clean the roof for dirt; to remove moss, if present, use a stiff brush; carry out all work with extreme caution to avoid damaging the slate;
- check the roof for integrity; if there are cracks, they should be sealed using a special composition; to prepare it, combine PVA glue, cement, water and asbestos;
- remove dust from the surface of the roof, for these purposes you will need to use water and a brush; upon completion of work, the roof must be completely clean, and before painting you should wait until it dries;
- Next, the surface is treated with a primer, which will reduce the risk of fungus and mold spreading on it.
In addition, the use of a primer allows you to increase the level of adhesion between slate and paint, while reducing paint consumption. Otherwise, if you do not prime the slate, the paint will peel off after a while.
Try to carry out slate painting work in calm and dry weather, while optimal temperature air temperature is 22 degrees. The easiest way to apply paint to a surface is with a sprayer. However, when using a sprayer, the amount of paint increases slightly in consumption. Be sure to apply the composition in two or even three layers, first waiting for the previous one to dry.
All information on the drying time of the composition is in the instructions, so be sure to read it before starting work. The maximum strength of the coating will be achieved within a day or two after application of the paint. It is not recommended to paint slate using a roller, as it is inconvenient and takes a very long time. The roller is suitable exclusively for flat slate. At the same time, follow the safety rules for staying at heights. Wear non-slippery shoes and insurance.
