- High adhesiveness to surface
- Thermal and frost resistant
- Water, acid and alkaline resistant
- Easy to apply (with a brush, roller, etc.)
- Provides protection in humid, acidic or alkaline environments
- Attaches and doesn’t corrode insulation (stone wool)
Appearance: homogenous black liquid mass.
Composition: petroleum bitumen, polymer, organic solvent and structuring compounds.
Is used to:
- attach rolled roofing and waterproofing;
- maintain and repair sealant roofing with and without reinforced base, and rolled and membrane roofing;
- seal foundations and slabs of buildings;
- waterproof interior and exterior concrete, reinforced concrete, metal, wooden and other constructs;
- seal welding seams and metal surfaces, including pipelines;
- establish vapor barriers;
- waterproof pools, water closets, bathrooms, shower cabins.
The working surface must be dry and cleared from dirt; snow, ice and frost must be cleared with a brush during winter period. Rust metal surfaces must be cleared mechanically.
Before using, the primer must be stirred throughout until homogenous mass. Add solvent if necessary until proper consistence. At sub-zero temperature it is recommended to keep primer at room temperature for 24 hours.
How to use:
Sealant is applied layer by layer with a brush, spattle or by pouring and levelling with a spraying brush.
Every next layer is applied after the previous one dries completely. Depending on the ambient temperature the sealant working temperature ranges from +5°С to +30°С.
