This practice provides detailed information on the handling and proper use of chemical-resistant resin grouts for filling joints of chemical-resistant brick or tile. For hand mixing, clean nonabsorbent pails or mortar boxes shall be used with paddles, trowels, or spatulas as mixing tools. For power mixing, a suitable size mechanical mixer operated at speeds so as to prevent air entrapment shall be utilized. Procedures for mixing and handling of resin grouts, setting of brick or tile into sand-cement or chemical-resistant setting beds, grouting of brick or tile, surface cleaning using steam or hot water, and curing for damage or contamination protection are discussed.

1.1 This practice provides detailed information on the handling and proper use of chemical-resistant resin grouts for filling joints of chemical-resistant brick or tile such as those covered in Specification C 658.

Note 1—Resin grouts and mortars are differentiated as follows: Resin grouts are applied to joints, generally ¼ in. (6 mm) wide, after the brick or tile are set in place and the setting bed has hardened (grouting or tilesetter's method). Resin mortars are troweled onto the brick or tile in sufficient quantity to achieve a ¹/₈-in. (3-mm) thick joint after the brick or tile are laid in place (buttering or bricklayer's method). (See Practice C 399.)
