Cleaning touches the snow, ice.If the pollution happened recently and the soil has not frozen, you can do without chemistry. It is necessary to remove the substance with a scraper, then rinse with soapy water. You can use a thinner white spirit, gasoline. For roofing use bituminous and emulsion-bituminous primers. Impregnation is applied directly to the prepared base to strengthen the top layer. During the drying process, the particles push moisture out of the pores and fill the gaps. After hardening, the plane of the slope does not absorb moisture, it is ready for applying mastic and gluing a reinforcing mesh. The soil is applied in any weather, limitation for use is surface moisture more than 15%. It is difficult to apply the solution on vertical walls and other planes, since it flows down. The first method is to soak a brush or roller in a solution and roll it out on a plane. Otherwise, the solution is poured from the container onto the surface in small portions at some distance. After that, the tool is leveled with a tool until the entire area is completely covered. Apply by brush or roller. Using a brush, scrub the primer into the surface. Ensure that only a thin coat is applied and that there is no pooling. Priming should extend at least 75mm beyond the area to be waterproofed. Leave to dry for 2­-3 hours before continuing with further work.

What is bitumen primer?

If the construction or finishing conditions do not require the use of a highly specialized composition, a universal version of a bituminous liquid is used. The primer is ideal for low pitched roofs, road construction and underground applications.
