Available in 90 and 210 minute set times. Quick Set Compound is specially formulated to provide excellent joint strength, even in poor drying conditions. Quick Set Compound permits heavy fills and faster joint finishing with low shrinkage. It is compatible with all types of gypsum board and may be used where a shortened joint finishing schedule is desired. Quick Set Compound is used as a prefill material for gaps in gypsum board construction that are wider than recommended and also in voids in above-grade interior concrete. It reduces joint deformities such as ridging and beading when used with gypsum board.
