HYPERDESMO®-PB-2K is a two-component mastic based on pure elastic hydrophobic polyurethane resins mixed with chemically cured pure bitumen.
Once the components are mixed and applied, it cures to form a seamless, durable waterproofing coating with exceptionally high elasticity (>2000%) and strong adhesion to many types of surfaces. Excellent mechanical and chemical resistance, UV resistant.
Mastic contains a small percentage of xylene, and can be thinned with xylene if necessary. Apply by brush, roller or airless sprayer in two or more coats with a minimum total consumption of 1.5-2.0 kg/m2.
