Flexible aromatic one-component, moisture cure polyurethane resin for sealing and priming bituminous supports.
This resin cures by air moisture giving a flexible coating. It is an excellent polyurethane primer for recoating old bituminous layers with polyurea or polyurethane waterproofing systems.
Apply by roller, brush or airless spraying equipment. Although not strictly necessary, it is recommended to use all the contents of the can. If not, ensure the remaining is kept tightly sealed after use. It can be applied as such, but often in a first coat, it is diluted up to 25% with Acrypol Solvent. Do not use other solvents for dilution. Usual amounts applied range from 100 to 300 g/m2.
