ABSTRACT This specification covers the requirements for aggregate-filled, resin-based, monolithic surfacing for use over concrete floors in areas where chemical resistance and the protection of concrete are required. The application methods for these floor surfacing shall include troweled, broadcast, slurry broadcast, self-leveling, sprayed, and reinforced. The resin chemistries include epoxy, urethane, polyester, and vinyl ester. Service conditions such as chemical exposure; traffic, and temperature conditions shall be considered in selecting the flooring system. The flooring material shall conform to the physical properties, chemical resistance, and performance requirements of the specific flooring system. The following methods shall be performed for the specific system to be tested: chemical resistance of mortars, grouts, and monolithic surfacing; test method for tensile strength of chemical-resistant mortars, grouts, and monolithic surfacing; test method for absorption of chemical-resistant mortars, grouts, and monolithic surfacing; test method for compressive strength of chemical-resistant mortars, grouts, monolithic surfacing, and polymer concretes; test method for flexural strength and modulus of elasticity of chemical-resistant mortars, grouts, monolithic surfacing, and polymer concretes; test method for determining the static coefficient of friction of ceramic tile and other like surfaces by horizontal dynamometer pull-meter method. SCOPE 1.1 This specification covers the requirements for aggregate-filled, resin-based, monolithic surfacings for use over concrete floors in areas where chemical resistance and the protection of concrete are required. 1.2 The application methods for these floor surfacings include troweled, broadcast, slurry broadcast, self-leveling, sprayed, and reinforced. The resin chemistries include epoxy, urethane, polyester, and vinyl ester. 1.3 Floor surfacings used as vessel linings are excluded from this specification. 1.4 The values stated in SI units are to be regarded as the standard. The values in parenthesis are provided for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
