Advantages:
- 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.
Surface preparation:
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.
Product preparation:
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.

| Consumption when striping, kg/m² | 0.55-0.95 |
| Consumption when patching, kg/m² | 0.45-0.75 |
Average consumption: 1.0-1.5 kg/m² per layer (sealant consumption depends on the number of layers applied).
Storage:
Must be stored in sealed containers in dry rooms protected from sunlight at -20°С to +30°С.
Must not be stored in living area or in proximity to foods. Keep away from children.
