bitumen is melted in a container with a blowtorch or on a furnace until it turns into a liquid state; Difficulty removing accidental surface splashes Difference from mastic Mastic is more viscous than primer Bituminous primer ISOBOX - a specially selected composition with organic thinners is used for any type of surface, is universal. 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.

What is bitumen primer?

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. 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 low viscosity bituminous primer for use on porous surfaces before remedial roof treatment, including pour and roll and torch-on felt applications. There are special varieties for different materials, the composition is selected taking into account the adhesion of the upper layers of the surfaces to be joined. Roofing molten resin is mixed into a container with gasoline in small portions (if you add it immediately, the gasoline will ignite);

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 substancesBituminous 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. 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. On metal surfaces, special store-bought products are used to remove bitumen. The drugs are sold in bottles or in the form of sprays, they do not leave marks. Bitumen primer manufacturers

TECHNICAL DATA SHEET BITUMEN PRIMER - CROMAR BUILDING PRODUCTS

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. This specification covers asphaltic primer suitable for use with asphalt in roofing, dampproofing, and waterproofing below or above ground level, for application to concrete, masonry, metal, and asphalt surfaces.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.
