Slate is one of the most popular roofing materials today. It belongs to the economy class. If ordinary slate is suitable for the construction of a canopy, then painted material should be laid on the roof of a private house. Therefore, quite often consumers are wondering which paint for slate is best suited.

Paint selection

Many consumers believe that by choosing an imported slate coloring product, they will get an excellent result. But this assumption may be wrong. Therefore, the issue should be taken seriously. If you decide to purchase a foreign-made product, then you should pay attention to Dachbeschichtung. This paint is made in Germany and is the most expensive product among imported products.

According to technical indicators, the paint is quite attractive: it is durable, has high adhesive properties and durability. However, the application of such a mixture can only be carried out on natural slate or tiles. Another paint for slate is Kilpi. It is made in Finland and contains acrylic. This indicates that the application can be carried out on almost any roofing material, for example:

• corrugated board;
• slate;
• metal tile.

For the price, this product is somewhat more attractive compared to the German counterpart.

Alternative Solutions

If you want to ennoble a slate roof, then you should also pay attention to the Polifarb / Akrofarb paint, which is a Polish product. These acrylic compositions are based on dispersion substances and are good because they dry out in the shortest possible time. As a result, it is possible to achieve color saturation and brightness. A joint product of manufacturers from Finland and Sweden - Eter Akva. It is a water soluble acrylate based paint. The mixture is resistant to aggressive alkaline environments and can be used to color not only slate, but also concrete.

Paints for slate from manufacturers of the countries of the former CIS

If you will be painting slate, then you can choose products manufactured under the Polifan brand. This Russian paint is used on slate, brick and concrete. The main advantages are:

• wear resistance;
• water resistance;
• color fastness;
• durability.

Ukrainian paint "Akrylama-Slate" is used exclusively for slate and is a viscous acrylic liquid on a water-dispersion basis. The basis for the Belgorod paint "Unisal" are acrylic elements on a water-dispersion basis. You can achieve the desired color by adding coloring pigments.

The covering has high resistance to an ultraviolet and an atmospheric precipitation. The composition of the Moscow paint "Butanite" contains polymeric substances, to which mineral-silicon ingredients are added during the production process. The main feature of the composition is frost resistance.

How to paint a slate roof

Slate painting should be carried out according to a special technology. If the roof is only planned to be covered, then the material can be painted on the ground, and then, after waiting for the layer to dry, lay it on the crate. If the roof is already arranged, then you have to sweat. When the slate was used for several years and never painted, its surface could be covered with a coating of fungal formations. Unpainted slate eventually becomes covered with a green coating, which absorbs moisture and creates a load on the roof structure.

In order to achieve a positive result, it is necessary to remove the top layer. It is better to use for this:

• brush with metal bristles;
• car wash;
• drill;
• grinder.

Using a wire brush, you can remove fungal deposits on a wet or dry surface, everything will depend on the severity of the plaque. If you decide to use an angle grinder or a drill, then you need to equip one of these tools with a brush attachment. The most versatile solution is a car wash, with which you can prepare the slate roof with water for painting, the jet will be supplied under high pressure.

As soon as the roof is cleaned of plaque, its surface should be treated with an antiseptic, which will exclude the possibility of the formation of fungus and mold. Painting slate provides for the preparation of the base of the roof also with a primer. Its application is carried out in the next step. This layer will improve the adhesion of materials. Using a primer can fill the pores, which will reduce paint consumption, in addition, the surface of the slate will be smoother.

The most reliable way of staining will be applying paint in 2 layers. The first layer will be the base. Work can be done with the following tools:

• roller;
• brush;
• sprayer.

Slate painting must necessarily provide for the need to prepare the surface of the covering material. It is important to inspect the canvases to exclude the presence of damage. Experts recommend paying special attention to the northern slopes, because it is on them that moss colonies are most often formed, which must be disposed of. If you decide to use a hand power tool for this, it is important to be careful not to damage the slate.

Cleaning, painting slate - these are the main stages of refining the described material. Once all microorganisms have been removed, the roof surface should be rechecked for integrity. If you notice small cracks or breaks, then they must be repaired with a special mixture. You can prepare it yourself using:

• cement;
• PVA glue;
• loose asbestos.

The glue is pre-diluted with water. The preparation process necessarily involves the removal of debris from the roof surface. It is important to dedust the base to be painted. This is done with a regular brush and water. The slate is then left to dry. Painting the slate on the roof will achieve an excellent result if you use car washers for preparation. After that, it will look like new.

Slate painting

Painting flat slate is carried out using the same technology as undulating. It is better to start work in cloudy cloudy weather, when the air temperature has risen above +15 ° C. Such conditions are the most optimal for drying the applied layer. Quite often, consumers are wondering if it is possible to apply paint at temperatures close to zero. In the instructions, you can find recommendations that the paint behaves perfectly under such conditions. However, experts do not recommend risking expensive materials. In addition, lower temperatures can increase the drying time of the applied layer. After the formation of the first layer, it is left until it dries. This period may differ for different materials. The layer will reach full strength within a few days, it is important that the roof surface does not get wet.

Methodology of work: reviews

If you decide to update the roof, it is recommended to read reviews about painting slate. Consumers say that it is best to use a sprayer or a wide brush to apply an antiseptic. It is important for the master to use protective equipment:

• glasses;
• gloves
• respirator.

When choosing a primer, it is important to pay attention to compositions that contain ingredients that protect the surface from the formation of moss and mold. Applying a primer, according to buyers, is best done in several layers. When painting slate with your own hands, it is best to purchase a primer from the same manufacturer as the decorative material that will be used in the final stage of refining the roof.

It is best to start work early in the morning when the weather is not too hot. The ideal humidity level for this is considered to be between 40 and 60%. This combination with a temperature of 20 ° C is quite rare, so it is recommended to follow the instructions.

It is important to pay attention to the processing of ends, hard-to-reach areas and corners. The base coat will take approximately 60% of the total volume of paint.

Conclusion

Consumers claim that an inhomogeneous layer may eventually result. To avoid this, the application of the second and subsequent coats must be carried out on a dry base coat. Typically, paint consumption is greater than that indicated by the manufacturer. Therefore, it is recommended to purchase material with some margin.

If you are tired of the color of slate, which has been covering the roof of your house for several years, then everything is fixable - we propose to deal with this problem by using paints and varnishes. So, we will find out what slate painting is and how to cope with this process on our own.

We paint slate - what, how and why?

Let's take as a starting point that you personally will have to put the roof of the house in order, which means that you will have to familiarize yourself thoroughly with such a rather responsible 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 and damage, durable and does not let water through even in heavy rain, then you can already start work. But in order to put the roof in order for the next ten years and be confident in the final result of your work, you still have to make a lot of effort. To do this, you will need to at least check, and if necessary, renew the entire roof or part of it.

If your coating is completely "leaky", then no amount of painting will help such a cracked roof. Here you need to safely buy a new slate, which will be the color you want. We will talk about the work that relates to such a process as painting slate on the roof, but for the material it has been in use for more than one year. So, your roof, after one decade or more, does not look very good, and let's just say it is completely unpresentable. Which means you need to get to work. As experts say, painting old slate is a work that is quite doable, but time-consuming 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 paintwork materials.

In order not to have problems in the future, you need to choose the right material. And do not listen to those who speak confidently that after painting such a product, the paint layer will crack and crumble literally after the very first cold weather. There are many examples when, after painting (with the right materials), painted slate has pleased its owners with its appearance for more than one year. So we take it as a rule - to accurately choose the paint and comply with the technological requirements during the work. In addition, you should consider what kind of slate you have - wavy or flat. It depends on what is better to paint - with a paint roller or 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 take not 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).

Slate coloring - the better to paint

The choice of paint, as well as slate, is quite large - the paint can be 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-based paint, which comes along with fillers, allows this mixture to form a super-strong and stable coating. And most importantly, in addition to a purely decorative function, it allows you to prevent the release of asbestos particles into the atmosphere (recall 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 a silicone primer. It is not compatible with other types of coatings.

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

If you take slate paint already on an acrylic basis, then it will also have excellent performance. Like silicone, it is applied in two layers, and also on a previously prepared surface. If there were previously old coatings on the product - for example, organosilicon or oil, then they must be removed, and completely. This paint is slightly cheaper than silicone, has excellent lightfastness 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 on a modified acrylate dispersion. Of course, it costs a lot, but, as experts say, its cost is justified by the high quality of the coating. A layer of such paint, as practice shows, remains elastic even at extremely low temperatures. The paint is also applied only after pre-treatment of the entire surface. Among the manufacturers there are many representatives of other countries. The main thing is that you choose not only for price, but also for quality, and also, when choosing paint, remember that it should be designed specifically for slate.

How to do everything with your own hands

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

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

Step 1: Checking the Surface

For high-quality staining, 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 operation for more than one year, then you should start with a "meticulous" inspection. Pay special attention to the coating - it is possible that you will find moss on it. It must be removed before painting.

Step 2: Prepare the site for work

Some experts advise cleaning the roof of vegetation with a drill and a 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 for breaks or cracks in 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 solved the issue with cracks and defects - we proceed to remove debris and dust. Only an absolutely clean surface will allow you to achieve the desired result when painting.

Step 3: Wash the surface of the coating

In order to wash the slate surface, we use household brushes and water. Just do not forget that after such water procedures, the slate should dry thoroughly. Do not try to do everything quickly and "just how". Better slowly, but qualitatively!

Step 4: Working with the primer

Further work with the coating provides for a primer. We process the slate coating with a special composition in order to increase the "cohesion" of materials. This process will 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 right, then it is better to paint 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 offspring can be used at fairly low temperatures.

There are two methods of applying paint - manually or with a spray gun. 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 is often not true. So, you have applied the first layer - now you need to let it dry thoroughly. Your paint package will tell you how long it takes before applying a 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 made a quality primer, then a second coat will be enough for you to get a uniform color and coverage. If, nevertheless, you are in doubt or the result did 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.

Tips from the pros - learn newbies!

• Moss on the roof should be sought from the north side.
• Washing the slate will be easier if you use a car washer.
• It is better to treat the surface itself after washing with antifungal drugs - this will increase the service life.
• It is more convenient to use than a paint brush.
• If the primer of the coating is of poor quality, the paint may lag behind.
• Make sure that all sections of the roof are treated with the composition.
• High-quality primer significantly reduces paint consumption.
• To avoid stains after painting (and they can be of varying degrees of color intensity), it is necessary to carefully prime the surface.
• Best of all, the paint dries and forms a reliable coating at an air temperature of plus 13 to plus 17 degrees.
• It is almost impossible for a non-professional to calculate from the first time how much paint is needed. The parameters indicated on the container are often underestimated, so do not rush to buy as much as possible and “for future use”.
• For different compositions of paint, the period required for the drying of the paint is different.
• Try to check the weather forecast ahead of time to avoid rain for a few days after painting.
• If you have to resolve the issue with multi-level coverage (for example, you have), it is better to use the services of professionals.
• If the roof is not of such a complex type, then it is advisable to work with at least two people.

If you appreciate the silence during the rain, and are going to make a roof on the roof of a new house from good old slate, this article is for you. After all, sooner or later you will come to the decision that all this goodness needs to be painted.

Indeed, mosses and lichens grow much less on an asbestos coating protected by a decorative layer, and such a roof is more protected from chips due to ice or wind-blown debris. That's just how to paint flat slate so that it does not peel off after a year? Now we will reveal all the cards!

Why paint flat slate at all?

Many are confused by this moment: if you save on building material by purchasing slate, then why paint it with expensive paint? What then is the savings? We explain:

1. First, we will reveal to you in this article a lot of tricks on how to save on painting and achieve excellent results.
2. And secondly, flat slate itself is not such a bad material, although it costs half as much as a metal profile. Remember that they have been covered with roofs for a very long time, and even unpainted slate can serve faithfully for several decades, while modern roofing materials have been used relatively recently and it is too early to talk about any durability.
3. And thirdly, it’s hard to come up with something better than slate when you need to cover a mansard roof: metal shamelessly rattles during rain, bituminous materials melt in the heat, but slate doesn’t get very hot, and absorbs all sounds remarkably.

What is our task? Paint the slate with a paint that will give it an aesthetic appearance, an even and smooth coating, protect it from moisture and prevent mosses from growing, and will not fade or peel off over time. Plus, a painted flat slate roof looks completely different!

The result of typical mistakes when painting slate is peeling paint after a year. That is why it is impossible to take ordinary paint for the facade or just outdoor work for slate. The point is not only in the special structure of asbestos fibers, from which a coating not intended for it can slide off in layers in a year.

Of all the structural elements of the house, it is the roof that is completely exposed to the scorching sun, hail and wind with small debris, and it also heats up the most. And all this already creates its own specific conditions, for which the same facade paint was not designed at all.

Least of all, simple enamel is suitable for painting slate. It does not just peel off over time - it hangs in tatters, which is why the roof looks very miserable. Although, we note, sometimes cheap metal paints have such high adhesion that they adhere well to slate. But this is already from the category of luck.

By the way, some home craftsmen go to the trick: they paint the slate with poured automotive paint, in two layers, with a 1: 1 solvent. Surprisingly, the result of this venture can really please: 5-10 paint does not fade and does not peel off. But this venture is risky.

The quality of the paint is also affected by ... coloring. Often people buy paint from one manufacturer and on one basis, and a coloring solution is completely different. Moreover, they are mixed incorrectly. Some problems of the final mixture will not come across the eyes, but on slate such paint will not last long. Still, chemistry is chemistry, and experimenting with incompatible compounds is not worth it.

Do it right:

Another reason for the peeled paint on the slate is the snow on the roof: as soon as it melts a little, and frost hits at night, an ice crust forms. She's just peeling off the paint. That is why it is so important that the coating layer on the slate is smooth, even slippery. For the rafter system, this moment is important: the less snow lingers on the roof, the lower the variable load on the rafters. And, therefore, the service life of the roof itself is longer.

The best paints for flat slate

Then how can flat slate be painted if ordinary paints are not suitable here? For flat slate, the modern market offers special impregnation paints that additionally protect such a roof from biodamage (moss, fungus and mold).

Polyurethane paints: cheap and cheerful

Polyurethane paints, after drying on slate, create a three-dimensional structure that protects the material well from contact with the environment. They are well resistant to sudden changes in temperature and have a high coefficient of elasticity.

Flat slate will receive maximum protection from modern solvent paints. These penetrate asbestos fibers three times deeper than water-based paints, and as a result, the coating lasts more than 20 years.

If you are looking for how to cheaply paint flat slate, then take a concentrate paint that needs to be diluted several times. But at the same time, it is better to dilute the paint itself a little less than according to the instructions.

Acrylic paints: rich colors

These are water-dispersion paints.

Acrylic paints are good because they give slate high hydrophobicity - water easily rolls off even from almost flat roofs, and snow quickly slides off. Thanks to this, water is in contact with the surface of the slate for too little time, and therefore the risk of leaks is significantly reduced.

Acrylic paints for slate are also good because they fill even the most imperceptible cracks, all the pores and irregularities of the slate.

The most popular paints of this series:

• One of the specially designed paints is Akrylakma. It is water-dispersion based on acrylic, designed specifically to give the slate decorative and protective properties, prevent the destruction of the slate and prevent the migration of asbestos into the atmosphere. Pay attention to this if you decide to paint the flat slate on the roof because of the “asbestosphobia” that is popular today.
• Of the modern brands, Triora paint for wave and flat slate has good reviews: affordable cost, moisture resistance and good light fastness. One of its strengths is the ability to tint, choosing the right shade.
• Of the available domestic options, we single out Novbytchim slate paint. It is diluted with water and dries quickly, has a large selection of shades, is resistant to weather vagaries, is equipped with protection against lichens and moss and is not toxic. What else is needed? The domestic paint "Optimist" is also distinguished by its resistance to fading.
• Dulux facade water-dispersion paint is also well suited for painting flat slates. It is intended only for outdoor work, it is, of course, not cheap, but it is of high quality. Easy to apply with a conventional roller - preferably three layers.
• Acrylic paints Polifarb and Akrofarb for slate are characterized by high drying speed and saturation of shades that delight the designer's eye.
• Expensive, but high-quality paint for slate "Killi" (manufacturer "Tikkurila"). Tikkurila paints generally differ in that they tolerate ultraviolet, snow, rain and temperature changes well.
• This paint is especially appreciated for its elasticity at low temperatures.
• Unisal. This paint is based on water dispersion and acrylic elements. Weather resistant and tinted.
• Polifan. It is a paint for concrete, slate and brick. Differs in durability of a covering and firmness of color.
• Acrylic. And this paint is already only for slate, on a water-dispersion basis.
• Butanite. This slate paint contains special polymeric substances with a mineral-silicon additive, which will also provide frost resistance to your roofing!

Important advice: to paint a flat slate with acrylic paint, you need to wait for the weather from +5°C to +35°C, clean and dry the sheets well and let them dry for 1-2 hours. In total, the polymerization process will take about a day.

Silicone paints: water-repellent properties

Unfortunately, on the windy side of the roof, such paint can burn out almost to gray in 10-20 years.

Acrylic-silicone paints: the best qualities

A relatively recent market novelty is acrylic-silicone paints. They combine the best qualities of both acrylic and silicone compounds.

So, for example, if you want to protect slate from dirt, cracks, mold and water damage, then purchase VDAK-1283 paint. This material has good water-repellent properties and passed serious tests during the production process: 90 cycles without changing the protective properties in a special chamber. This suggests that such paint will behave remarkably in the Russian climate for at least 10 years. And, which is good, it can be tinted according to the RALL and NCS catalogs, respectively.

In Russia, the largest manufacturers of such paints are Penta, Tiprom and Sofeksil.

Liquid rubber: perfect coverage

If you notice, recently more and more experts recommend painting slate for roofing with rubber paint. It includes special materials that eventually create a dense protective film on the surface, elastic and durable. It never delaminates - even over time and in harsh terrain. And special pigments do not allow the color to fade even after 5 years.

The only serious disadvantage of rubber paints is their toxicity. Therefore, you will need to work with such paint in the open air without strangers and with mandatory protection of hands and respiratory organs.

One of the most popular rubber paints for slate is Super Decor. You need to paint it in sunny, dry weather - this is the only requirement. Good reviews are also about Rezolux rubber paint, which is sold together with a special primer.

An interesting video about rubber paint:

Liquid plastic: new technologies

And this is already a completely new word in science:

How is flat slate painted at the factory?

You will be interested to know how slate is dyed in production. So, the simplest technology is applying paint to the outside of the sheets. But such slate is just "painted". If additional surface protection is needed, then a layer of paint is applied not only at least twice, but also under special conditions: conveyor lines heated to a certain temperature.

Many home craftsmen try to repeat this technology in their own yard in their own way: they simply lay flat slate on the grass on a hot sunny day, and it heats up from the rays. Then they paint and admire as a result a beautiful and durable roof. Cheeky, isn't it?

Sometimes, of course, a special pigment is added directly to the raw mix, and then the slate is already produced in “color”. Its advantage is that such slate does not fade at all, and when cut, the edges have the same color as the sheet itself. Even strong scratches will not be noticeable. But such a slate is much more expensive than usual.

Therefore, some manufacturers use a combined version: because. slate, like plywood, consists of several layers, only the top is painted. In other words, the top layer is deeply impregnated with paint, and not just painted. And it is only 10% more expensive than ordinary gray.

Step by step painting tutorial

Competent painting of flat slate implies the right preparation and the right technology.

Stage 1. Cleaning

First of all, thoroughly clean the slate. And if you need to paint old material, then in addition to a synthetic brush, you will also need a metal one to tear off all the moss and lichen.

Such a harsh cleaning will of course remove the top layer of slate, and therefore it will need to be coated with a deep penetration acrylic primer. If this is not done, no paint will stick, no matter how expensive it may be.

Stage 2. Inspection

The second thing is to carefully inspect the slate for cracks. Before painting, flat slate must be thoroughly cleaned and even repaired. If the crack is very thin, like a thread, then nothing needs to be done with it: a couple of layers of paint will flow into the crack themselves and the problem will be solved.

For a wider crack, you will need to make a patch. To do this, take fiberglass (in extreme cases, burlap with a tarpaulin is also suitable), soak it with thick paint for outdoor work, coat the crack itself and plug the patch. Let dry and paint again.

Stage 3. Processing

The third step is to treat the surface with antifungal drugs. As practice shows, they significantly increase the life of the roof of this material.

Stage 4. Primer

The fourth step is to prime the flat slate with those special compounds recommended by the paint manufacturer. This treatment ensures reliable contact between slate and paint. If you skip this step, the paint itself will then lag behind.

Please note that if you prepare the slate before painting, always dilute the primer with water 30% more than stated in the instructions, otherwise you will get a poorly permeable film. The paint on it will be taken, but not firmly and after 5 years it will lose its appearance.

By the way, if you have purchased expensive foreign paint, it is not necessary to use a primer beforehand.

Stage 5. Painting

Before use, be sure to mix the paint well so that the coating is uniform later. Starts to thicken? So dilute with a small amount of bitlacetate or white spirit.

Apply paint to flat slate only after following these points:

• The surface of the slate must be thoroughly cleaned from the old coating, dirt and dust.
• The air temperature must be at least +5°C.
• Weather - without wind and rain, there should be no dampness.
• If the air temperature outside or in the room where you paint the slate is not lower than + 20 ° C, then the paint will dry completely in two hours. If it is cooler, then it will take more time, be sure to consider this.

It is necessary to paint flat slate only in a horizontal position: only in this way the paint will evenly fill all the bumps and roughness. But in a vertical position, this effect cannot be achieved.

Based on two layers, for each square meter of flat slate, you will need about 100-200 grams of paint. The most durable coating is obtained by painting flat slate in two coats of paint, taking a break of one hour between approaches.

And here is a rather important question: where is it better to paint flat slate - on the ground or on the roof? On the ground, of course, it is easier, and the necessary horizontal is created for a flat surface of the coating. But when climbing to the roof, already painted slate is easy to scratch. So what to do? Experienced builders do this: the first layer of paint is applied on the ground, with a brush or roller, and the second - already at a height and with an airbrush.

But what if the slate is already painted in the right color, and you don’t want to change it? Do I need to apply a new coat of paint? If the point is only that moss is constantly growing on flat slate, even a colorless hydrophobic impregnation can solve the problem. Its secret is that now oxygen is not supplied to the roots of sprawling plants, and the moss will simply fall off. As a result, the slate is cleaned and even brightens.

That's all the secrets!

Slate is the most popular roofing material, although it loses to others in decorative properties, and the natural gray color darkens over time under the influence of precipitation, which makes the roof nondescript, moreover, she starts to break down.

To make the service life as long as possible, painting slate roof 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 the slate is made of asbestos and concrete, its structure is somewhat similar to drywall and concrete slabs, so all painting work is carried out in the same way. It is recommended to use the following types of paint:

• acrylic;
• Polymer;
• Solvent paint for slate.

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

Slate surface needed clean thoroughly with the help of metal brushes from growths of moss and dirt, if necessary, rinse with water, if there are holes in the roof, these areas should be replaced, and if there are small cracks, they are sealed with cement.

After the roof surface has dried, apply each next one after the previous one has dried, and then apply the paint. It is better to paint with an ordinary brush or sprayer, in three layers.

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

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

Most of them are performed acrylic or silicone based, such as organosilicon paint "KO-slate", the composition includes various fillers and dye. After drying, it forms a durable coating that is resistant to damage, and also prevents the removal of asbestos particles into the atmosphere.

One of the most famous - paint "Triora" on acrylic basis, 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 able to maintain elasticity even at very low temperatures.

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

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

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

The roof should be carefully examined for cracks or holes, if any, fragment will need to be replaced and cracks are repaired with cement plaster.

After preparing the surface, it must 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 gun for large roof areas or with a wide square brush for smaller areas.

Whatever one may say, the correct painting of something is ensured by two things - the right choice of coloring agent and, of course, thorough adherence to the technology of its application. Such roofing material as slate is no exception in this regard - with the right approach to business, it is possible to enhance its aesthetic characteristics for a long time, and this can be done using various materials. In this article, together with the website, we will deal with the question of how to paint slate - we will study the materials used for this purpose and get acquainted with the technology of painting it directly.
