CAN/CGSB-25.20-M88

1. SCOPe 1.1 This standard applies to unpigmented sealer intended primarily for use on resilient and nonresilient floors other than those of wood or cork. 1.2 Intended Uses - The sealers to this standard are intended for use in sealing resilient and nonresilient surfaces prior to the use of maintenance finishes. Type 1 solvent-based sealer should be used only on nonresilient surfaces, as for example concrete, terrazzo, marble, magnesite, ceramic and slate. Type 2 water-based sealer may be used on nonresilient surfaces but should be used on resilient surfaces such as asphalts, linoleum, vinyl, vinyl asbestos, rubber and mastic. It is the recommended choice in fire-hazard areas such as furnace rooms and where there is an open flame, and in hospital and kitchen areas where solvent fumes are not permitted.
