Petroleum bitumen melt at temperatures above 75 - 90 ° C, therefore, they are confidently used in areas with hot summers. Bitumen is a mixture of air-blown tar with the residue of viscous crude asphalt oil or heavy distillate. Cromar Bitumen Primer is a bituminous solution designed to prime and seal porous roof surfaces, promoting adhesion for waterproofing systems Bitumen Primer should be applied by brush ensuring an even coat, or applied evenly by airless spray 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. Unleaded gasoline does not contain lead additives, which ensures its environmental friendliness. In Russia, only such types are sold at gas stations. Terms of use Surface moisture should not exceed 15%

The integrity and effectiveness of subsequent layers depends on the quality of the first priming. The surface is cleaned of debris, in the rainy season remove moisture from the roof. A bitumen-based primer will harden and adhere to a wet roof, but it is better if there is less free moisture. Cleaning touches the snow, ice. 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. Bituminous the primer without polymer and emulsion additives contains only resin and organic thinners. It is suitable for all types of roofing and other works. However large your project, here at Drainage Superstore we have a selection of bitumen primer products available for you to choose from, from well-known and reputable brands Cromar and Everbuild, who have years of experience in the roofing industry. bitumen is melted in a container with a blowtorch or on a furnace until it turns into a liquid state;

Approximately 3-­6 hours depending on drying conditions. May be extended for heavy coatings or in cold weather. IKOpro SA Bitumen Primer is a rubber-modified bituminous priming solution designed to seal and prepare surfaces for the application of self-adhesive roofing and waterproofing systems. ASTM D41, 2005 Edition, February 1, 2005 – Standard Specification for Asphalt Primer Used in Roofing, Dampproofing, and Waterproofing molten resin is mixed into a container with gasoline in small portions (if you add it immediately, the gasoline will ignite); Bitumen Primer is a low viscosity bituminous primer for use on porous surfaces before remedial roof treatment, including pour and roll and torch-on felt applications.If on the old roof there was roofing material with fine-grained dressing, up to 1 kg of soil will go per square. Reduce consumption by thoroughly cleaning the surface of the roof or walls from dust and dirt. The layer of debris absorbs the agent, therefore the penetration depth decreases and the consumption increases. Preparation for use 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.
