The prime coating is necessary to achieve strong adhesion of materials to porous, rough and dusty surfaces. Bitumen primer is a solution containing high quality oil bitumen and specially selected organic solvents with softening temperature at no lower than 80°C. Primers are ready to use products for single coat applications suitable for all types of substrates.

Application areas:

• to prepare substrate for application of torch-on, self-adhesive or other types of waterproofing materials

Bitumen primer TECHNONICOL № 01 should be applied to prepared surface clear of any debris or sharp projections. The primer should be applied in continuous coat using roll or brush penetrating the surface and providing smooth and well adhered base for subsequent waterproofing layers.

Consumption:

• 0.25–0.35 L/m² (1 L per 3.33 m²)

The TECHNONICOL Nr. 03 polymer-bitumen primer consists of a solution of oil bitumen, polymers and adhesive additives in organic solvents. The material has a short drying time and reliably protects the metal surface against corrosion before installation of the waterproofing layer. After the waterproofing installation, the adhesive strength of the welded-on material to the base increases.

Application areas:

• for processing the surfaces of framework of bridges before the installation of waterproofing materials, prime-coating of sandy-cement, concrete and other surfaces before installation of welded-on, self-adhesive roofing and waterproofing materials

The primer is applies by using large and small paint brushes, rollers or an airless spraying unit.

Consumption:

• 0.20–0.30 L/m² (1 L per 4 m²)

TECHNONICOL Nr. 04 is a bituminous emulsion primer produced by bitumen dispersion method. The material does not contain solvents, has a neutral smell, hence is completely harmless and is suitable for internal weatherproofing applications.

Application areas:

• to prepare substrate for application of torch-on, self-adhesive or other types of waterproofing materials

TECHNONICOL Nr. 04 primer should be applied to prepared surface clear of any debris or sharp projections. The primer should be applied in continuous coat using roll or brush penetrating the surface and providing smooth and well adhered base for subsequent waterproofing layers. Apply at temperatures +5°C – +40°C, water can be added if necessary.

Consumption:

• 0.20–0.35 L/m² (1 L per 3.33 m²)
