Process for coating a surface and the coated surface

摘要: A water-proofing/sound-proofing coating composition comprises, in order, from a surface to be coated (A) an adhesion promoter, (B) seal coat comprising (1) polyurethane (2) heat absorber, (3) nonvolatile extender, (4) volatile solvent, and (5) inert filler, (C) membrane formed (a) mixture of high molecular weight polyols low chain stiffeners (b) polyisocyanate, extender solvent. The surfacing can also include overlay wearing such as asphalt concrete. process is provided for preparing cast-in-place applying primer coated, seal-forming primed surface, allowing the stand time sufficient allow entrained gases escape (D) sealforming membrane-forming polyol stiffener, substantially polyurethaneforming reaction catalyst.
