The values given in parentheses are for information only. 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.

mastics are distinguished by higher viscosity, fillers in the form of chalk, mineral chips, and other particles are included in the composition; Bitumen Primer is a quality grade, highly penetrative, bituminous solution for priming surfaces prior to the application of bituminous materials, self-seal membranes and flashing tapes. Heavy duty formula making it suitable to prime concrete roofs and floors, cementitious screeds/renders, bitumen felt, weathered bitumen, mastic asphalt, weathered, corrugated iron and steel. 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 Cromar Bitumen Primer is a bituminous solution designed to prime and seal porous roof surfaces, promoting adhesion for waterproofing systemsThere are no other inclusions or inhomogeneous impurities; toxic substances, for example, toluene, are not used for manufacturing. 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.

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. There is no need to choose between the two materials as they complement each other. After priming the base, you can apply a mastic for gluing the reinforcing glass fabric. Varieties of bituminous primers 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. There are low-quality products on the construction market that are produced with deviations from technology. As a result, the primer dries for a long time or does not set at all. The surface remains damp, unsuitable for adhering to the following materials. 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.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.

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. Solvent-based primer to prepare porous, rough, dusty surfaces. Suitable as a primer before applying flashband. Ideal for cold, damp conditions. Fast drying and easy to apply. Covers approx. 6 m²/Ltr. If the primer is used for gluing layers of material, wait for the first layer to dry for 4 - 5 hours, then apply a layer of glue. 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.Approximately 3-­6 hours depending on drying conditions. May be extended for heavy coatings or in cold weather. Bituminous primer is different from mastic properties, purpose of application and composition... Materials are intended for different jobs. The primer holds the top layer of the base together, protects against moisture, deterioration, and ensures effective adhesion. The mastic is used as a waterproofing layer and an adhesive layer for laying reinforcing mesh and finishing roofing. Difficulty removing accidental surface splashes Difference from mastic Mastic is more viscous than primer 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. Bitumen primer is designed to seal and prime surfaces such as concrete, masonry and timber, before applying bitumen roofing. It can also be used to prepare small porous surfaces before remedial roof treatment.

When processing a roof made of reinforced concrete slabs, the surface of the elements is treated and the butt joints between the panels are impregnated. The subsequent layer of mastic is also placed in the seams, therefore, using a primer, they provide adhesion of materials in a hard-to-reach place. Road the top layer of the treated surface is reinforced base for the subsequent laying of the finishing or intermediate layer; Bitumen Primer should be applied by brush ensuring an even coat, or applied evenly by airless spray 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.By definition, a primer comes first and serves as a base for what should follow — whether it’s attending the primary grades at the beginning of school, priming an engine to start or using a primer coat applied prior to painting a wall. Similarly in commercial roofing, a primer is used as the first step in the application of a roof coating or membrane to aid in the proper bonding of the product to the surface. A layer of primer on the surface facilitates roof waterproofing work. Self-adhesive and weld-on coatings are better glued to the processed plane. Structure The primer contains no toxic substances
