Anotation

This specification describes the required properties and test methods for high-solids content, cold liquid-applied elastomeric membrane with integral wearing surface for waterproofing building decks not subject to hydrostatic pressure. This specification does not include specific requirements for skid resistance or fire retardance, although both may be important in specific uses. The properties to which the materials will be tested upon for conformance are as follows: weight loss of base coat; low temperature crack bridging; adhesion-in-peel to cement mortar and plywood substrates after water immersion; chemical resistance after water, ethylene glycol, and mineral spirits exposure; weathering resistance, recovery from elongation, tensile retention, and elongation retention; abrasion resistance; and stability.
