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. It is based on a pure elastomeric hydrophobic polyurethane resin extended with chemically polymerized virgin bitumen. Apply with brush, roller, spatula or airless spraying. Minimum consumption: 1.0-1.5 lit/m2.
Waterproofing and protection of:
LIMITATIONS: Not recommended for unsound substrates.
Can be successfully applied on:
Concrete, fibrous cement, mosaic, cement roof tiles, old (but well adhered) acrylic and asphalt coats, wood, corroded metal, and galvanized steel. For information about other substrates, please contact our tech department.
Concrete substrate conditions (standard):
Primer selection for special conditions and substrates: Please refer to the Primer Selection Table.
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.
Choose primer from the Primer Selection Table and follow the application instructions given on its prospectus.
Mix equal volumes of the two components manually or with a low speed (300 rpm) mixer. Apply mixed quantities immediately. Pot life (of mix): 30-45 minutes at 20 oC. For application by airless spraying, the mix may have to be thinned with a small quantity of SOLVENT-01, especially for low-power applicators.
Apply HYPERDESMO-PB-2K (or HYPERDESMO-PB-1K) locally over any cracks larger than 1 mm before the main coat.
Apply the material with brush, roller or spatula.
Minimum consumption: 1.0-1.5 lt/m2.
Clean tools and equipment first with paper towels and then using SOLVENT-01. Rollers will not be re-usable.
2×5 lit, 2×20 lit and 2×200 lit.
Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25 oC. Cap tins air tightly in order to store unused quantities.
Contains a small quantity of volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. In closed spaces use ventilators and carbon active masks. Keep in mind that solvents are heavier than air so they creep on the floor. The MSDS (Material Safety Data Sheet) is available on request
In liquid form (before application): ~90% dry matter in Xylene.
