Surface priming

Primer Produced after the layer has dried antiseptic. Due to the deep penetration of the primer into the pores of the slate, its surface is strengthened and excellent adhesion to the slate of the applied paint layer is ensured. The primer should be applied with a roller or with a sprayer. For best results, you should use a primer from the same manufacturer as the paint. You should not abandon the use of primer, because without it, due to the high porosity of slate, despite the increase in paint consumption, you will not be able to achieve uniform staining of the entire surface.

Painted sheets

After the primer has dried, you can proceed to applying the so-called first coat of paint. It is considered the main, basic. You should carefully paint over all the ends of the slate coating, hard-to-reach places and corners.

About two thirds of the amount of paint and varnish material is consumed to create a base coat (one third is used to create the finishing layer).

To obtain a durable coating, you should use a special acrylic paint, and painting work should be done in the summer, in dry, but not very hot weather.
