Slate painting

Slate has long been considered one of the main materials that overlap rooftops. However, not all owners were serious about painting the roof, not considering it mandatory. However, painting slate increases its life and makes the house more attractive.

Preparatory work

Surprisingly, the owners often take up painting slate several years after the roof of the house is covered with roofing. During the elapsed time, the roof of slate loses its presentation and, before it is renewed, it first needs preparatory work. Before painting, slate must be cleaned in one of the ways below.

• Slate can be cleaned with its own ordinary metal brush. With this method, you need to spend a lot of work and time. At the same time, the result of the work will not always be satisfied in a qualitative way. The main thing in this method - the roof after the work should be dry.
• The roof can be cleaned and in a different way - with a special nozzle, worn on the grinder. Thanks to the power tools, the work performed will be carried out with higher quality, but all the time it takes to clean the slate, all one will have to spend a lot.
• The third method gives relatively best results, and the work can be carried out in different weather conditions. In this method, slate is treated with water, which washes away contaminants under high pressure. For high-quality performance of such work, a special wash is required, which will create a high pressure for a jet of water. Choose the pressure you need optimal - about 250 atmospheres. If the pressure of the jet to create higher, then the slate may crack or break. With insufficient pressure, it will be difficult to clean the surface.

Note! The advantage of using a special car wash lies in the fact that the roof area of ​​100 m? can be cleaned in just 1 day.

Slate processing

After cleaning, it is necessary to treat the slate with an antiseptic and hydrophobize it. The fact is that the roof, although it will be cleared of dirt, parasites will live in the microcracks of the material. Thanks to the antiseptic they stop growing and multiplying. Impregnation with an antiseptic can be made with an ordinary brush, but using a sprayer will give better results. In order not to be exposed to the harmful effects of the applied substance, the work should be carried out with gloves, glasses and a respirator.

Note! Since the spores of fungi live in a moist environment, the surface of the slate must be treated with a water-repellent agent.

According to its characteristics, slate is sufficiently porous; therefore, frequent exposure of the material in a wet environment leads to early destruction. To prevent this from happening, and the slate served for a long time, it is necessary to conduct water repellency. As for the painting itself, it not only gives the roof an attractive look, but also performs practical functions. An additional layer of paint well protects slate from destruction. In addition, the painted material is more resistant to severe frost. It should also be noted that the painting of slate should be done even at the stage of the construction of the roof. This is not always done, but after a while it is never too late to paint the roof.

Paint selection

From the right choice of paint depends not only the attractiveness of the surface on the roof, but also reliable protection of the roof. Today for slate the most suitable enamel and acrylic compositions. They are recommended by experts, since such paints fill all microcracks in the material well. In addition, the resulting film after painting perfectly protects the slate from precipitation. When a house is located in a region where weather conditions change dramatically and the temperature regime has a wide temperature range, the enamel for painting should be chosen quick-drying.

The result of painting slate depends not only on the selected composition, but also on the technology of the work. The process of exterior roof treatment consists of three stages:

• pre-primer;
• paint application for the first entry;
• finish coloring.

Primer поверхности шифера

Before painting, slate should be treated with a deep penetration primer, which will significantly strengthen the surface of the roof. Applying the first coat of paint over the primed roof is much easier and more efficient, since the distribution of the composition over the surface will be more even. In addition, the consumption of the coloring matter will be significantly less. It is recommended to spend up to 150 g of the product to prime 1 slate sheet well. The best tool for applying a primer is a sprayer, which needs to perform work at a positive air temperature in the corridor of 5? 30? C.

For complete drying of the composition is enough for half a day. Painting can not begin earlier than this time passes. When priming it is necessary to observe safety precautions - hands and eyes must be protected. If the primer is carried out correctly, the subsequent painting will give much better results compared to the option without preliminary surface treatment, since its service life will significantly increase.

Painting slate roof

• The first layer of paint applied on slate is the main one, therefore the paint and varnish materials on the first pass are much more than on the finishing works. This is about 2/3 of the total consumable paint. After passing the first layer there should be no gaps. The focus is on corners and ends. Also, do not forget to go paint in places that are difficult to reach.
• Before you paint the surface with a finishing coat, you need to wait until the paint dries after the first run. The second layer should be applied neatly and slowly. After the second pass, you need to make sure that there are no streaks, and the entire surface of the slate was solid. Paint can be applied with a roller, brush or spray gun. Before work, you must carefully read the instructions for use.

Properly painted roof, covered with slate, will be long exploited and it is pleasant to please the eye of the owners and others.
