This standard applies to unpigmented sealer intended primarily for use on interior resilient and nonresilient floors other than those of wood or cork.

Sealers manufactured to this standard are intended for use in sealing resilient and nonresilient surfaces. These sealers may be used prior to the application of maintenance finishes or as stand-alone sealer finishes. Type 1 solvent-based sealer should be used only on nonresilient surfaces such as concrete, terrazzo, marble, magnesite, ceramic and slate. Type 2 water-based sealer may be used on resilient surfaces such as asphalt, linoleum, vinyl, vinyl composites, rubber and mastic, or on nonresilient surfaces as recommended by the manufacturer. Type 2 water-based sealer is the recommended choice in fire-hazard areas such as furnace rooms and where there is an open flame, and in hospital and food-processing areas where solvent fumes are not permited.

The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjuction with any existing applicable regulatory requirements prior to its use.
