Foster Childers CP-35 Chil-Perm WB Vapor Retarder Coating

Chil-Perm WB CP-35 is an effective, high performance, water based, vapor retarder coating designed for all interior and exterior, low temperature and some dual temperature applications. It is fast drying and forms a tough, flexible dry film which retards the flow of vapor through an insulation system. Chil-Perm vapor barrier mastic looks heavy but spreads easily. It can be applied in a relatively heavy film or brushed out into a thin, smooth film.
