Bitarel Multi-Purpose Sealant

For all types of works
TS BY 690590146.016-2016

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.
