Mixes smoothly and easily with lime to produce smooth-trowel and sand-float finishes for normal interior walls and ceilings
Produces hard, crack, and abrasion-resistant surfaces
Unaggregated for use over sanded basecoats
A smooth trowel finish should not be used over lightweight aggregate gypsum basecoat applied over metal lath (a sand float finish is for this application)
Where the gypsum basecoat is Structo-Lite brand basecoat or contains lightweight aggregate (perlite or vermiculite) over any plaster base except metal lath, and when a smooth trowel finish is used, the finish coat should be Red Top gauging plaster and lime with the addition of 1/2 cu
ft
of perlite, or 50 lb
of No
1 white silica sand per 100 lb
