Slate painting. How and what to properly paint the slate?

Slate is one of the popular roofing materials today. It refers to economy class covers. If a normal slate is suitable for the construction of the canopy, then the colored material should be laid on the roof of the private house. Therefore, quite often consumers ask themselves which slate paint is the best.

Paint choice

Many consumers believe that when choosing an imported product for staining slate, they will get an excellent result. But this assumption may be erroneous. Therefore, the issue should be approached seriously. If you decide to purchase a foreign product, you should pay attention to the Dachbeschichtung. This paint is made in Germany and is the most expensive product among import offers.

According to technical parameters, the paint is quite attractive: it is strong, has high adhesion properties and durability. However, this mixture can only be applied to 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:

• Profiled sheeting;
• slate;
• Metal tile.

At a price this product is somewhat more attractive in comparison with the German analog.

Alternative solutions

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

How to paint a slate roof

Slate painting should be carried out by 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 drying of the layer, to lay on the crate. If the roof is already arranged, then you have to sweat. When the slate was exploited for several years and never stained, its surface could be covered with a coating of fungal formations. Unpainted slate eventually becomes covered with a touch of green, which absorbs moisture and creates a load on the roof structure.

In order to achieve a positive result, you must remove the top layer. To use for this purpose it is better:

• A brush with a metal pile;
• Car wash;
• drill;
• Bulgarian.

Using a metal 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 one of these tools must be equipped with a brush attachment. The most universal solution is a car wash with which you can prepare the slate roof with water for coloring, the jet will be fed under high pressure.

Once the roof has been cleaned of plaque, it should be treated with an antiseptic that will prevent the formation of fungus and mold. Painting slate provides the preparation of the base of the roof and primer. Its application is carried out at the next stage. This layer will improve the quality of the adhesion of materials. Using a primer, you can fill the pores, which will reduce the consumption of paint, in addition, the surface of the slate will be more smooth.

Specialist's recommendation

The most accurate method of coloring is the application of paint in 2 layers. The first layer will form the basis. The work can be done with the following tools:

• Roller;
• Brush;
• Spray.

Additional tips for preparing

The painting of the slate must necessarily provide for the preparation of the surface of the covering material. It is important to inspect the cloth to avoid damage. Special attention is paid to the northern slopes, because they are the most often formed colonies of moss, which must be disposed of. If you decide to use a manual power tool for this, it is important to be careful not to damage the slate.

Cleaning, painting slate - this is the main stages of refinement of the material described. Once all microorganisms have been removed, the surface of the roof should be checked once again for integrity. If you notice small cracks or breaks, they should be sealed with a special mixture. You can prepare it yourself using:

• cement;
• PVA glue;
• Asbestos.

The glue is previously diluted with water. The preparation process necessarily involves removing debris from the roof surface. It is important to de-dust the substrate to be painted. This is done with a conventional brush and water. The slate is then left to dry. Painting slate on the roof will achieve an excellent result, if for preparation use car washers. After that, it will look like new.

Slate coloring

Painting of flat slate is carried out using the same technology as wavy. It is better to start work in cloudy overcast weather, when the air temperature rose above +15 ° C. Such conditions are the most optimal for the drying of the applied layer. Quite often, consumers are wondering whether it is possible to apply paint at temperatures close to zero. In the instructions it is possible to meet recommendations that the paint behaves perfectly under these 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 full strength of the layer will reach within a few days, it is important that the roof surface is not wet.

Methods of work: feedback

If you decide to upgrade the roof, it is recommended to read the reviews on the painting of slate. Consumers say that it is best to use a nebulizer or a wide brush to apply an antiseptic. At the same time, it is important for the master to use the means of protection:

• Points;
• Gloves;
• Respirator.

When choosing a primer, it is important to pay attention to compounds that contain ingredients that protect the surface from the formation of moss and mold. The application of a primer, as the buyers say, is better done in several layers. When painting the slate with your own hands, it is best to purchase a primer of the same manufacturer as the decorative material that will be used in the final stage of upgrading 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 the limit of 40 to 60%. This combination with a temperature of 20 ° C is rare, so it is recommended that you follow the instructions.

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

Conclusion

Consumers say that in the end, a heterogeneous layer can result. In order to avoid this, the application of the second and subsequent layers should be carried out on a dry base layer. Typically, the paint consumption is greater than that indicated by the manufacturer. Therefore, it is recommended to purchase the material with some margin.
