scope:

1.1 This specification covers the requirements for chemical-resistant resin grouts for filling joints of chemical-resistant brick or tile units. (For mortars, see Specification C395.)

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.

Note-Resin tile grouts are applied to joints, generally 1/4 in. (6 mm) wide, after the chemical-resistant brick or tile units are set in place on a horizontal substrate (grouting or tilesetters method). Resin mortars are trowelled on the sides and bottom of brick or tile units, generally 1/8 in. (3 mm) in thickness, before the brick or tile units are laid in place (buttering or brick-layers method). Refer to Specification C395.
