HYPERDESMO-PB-2K Two-component polyurethane membrane for waterproofing & protection
Description :
HYPERDESMO-PB-2K is a fast-curing, two- component, bitumen-extended polyurethane fluid. It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties.
Usage :
- non-potable water tanks
- light roofing made of metal or fibrous cement
- flower pots and roof-top gardens
- verandas and balconies (under tiles)
- bathrooms (under tiles)
- Waterproofing and protection of Gypsum and cement boards, polyurethane insulation foams, asphalt membranes
- basements
- foundations
- bridge platforms
Features and benefits :
- Good chemical resistance
- Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance
- Resistance in the cold
- No thinning is required but SOLVENT-01 may be used
- Excellent adhesion on almost any surface, with or without the use of special primers
- Its low modulus gives it excellent substrate crack-bridging properties
- Being a two-component product means that the quantities not mixed can be stored for later use
- Thick, bubble-free, membrane possible
- Fast curing
- Components easily mixed, 1:1 by volume
- Good water vapor barrier properties
How to use :
Clean the surface using a high pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes, etc. must be removed
Priming:
Choose primer from the Primer Selection Table and follow the application instructions given on its prospectus
Mixing:
Mix equal volumes of the two components manually or with a low speed (300 rpm) mixer. Apply mixed quantities immediately
For application by airless spraying, the mix may have to be thinned with a small quantity of SOLVENT-01, especially for low-power applicators.
