Quick-Set and Slow-Set formulations are unaggregated for use over sanded basecoats. Perlite Aggregate formulation includes mill-mixed fine aggregates for use over lightweight basecoats. Produces hard, crack- and abrasion-resistant surfaces over gypsum basecoats. (Quick-Set formulation sets in 30-40 minutes; Slow-Set formulation sets in 50-75 minutes.)
