BITUMEN-POLYMER PRIME COATING
Ready to use BITUMEN-POLYMER PRIME COATING is intended for surface preparation of bridge and flyover decks of steel orthotropic plates or reinforced concrete slabs before installation of polymer-bitumen waterproofing materials. It is also used for surface preparation before the installation of self-adhesive polymer-bitumen membranes. The prime coating is necessary for ensuring the strong adhesion of the bitumen-based waterproofing materials to porous, rough and dusty surfaces.
BITUMEN-POLYMER PRIME COATING presents a mix of high-quality bitumen, polymers, adhesion additives and specially selected organic solvents. The primer has an excellent penetrability and very short drying time. Due to the use of polymers, the primer has an enhanced softening temperature and can be used even on steel surfaces.
Ready to use primer is applied to a surface by roller, large or small brush. It is applied to the base at once that grants additional convenience and enhanced performance.
The product should be stored in a dry place protected from direct sunlight at temperatures from -20°C to +30°C. Shelf life – 12 months.
