Abstract
A novel cement-based composition comprising a cement powder, a polymeric latex composition, and a water-soluble polysaccharide compound is disclosed. This composition is useful in adhering ceramic and vitreous tiles to plywood substrates. The composition can also be formulated to be an underlayment for preparing a substrate for flooring including carpet, tiles, wood flooring, etc.
Claims12
A cement adhesive composition for a cellulosic or non-porous substrate comprising:
- (a) about 5 to 99 parts by weight of a cement powder;
- (b) about 0.25 to 75 parts by weight, based on the polymeric solids content, of a polymeric latex composition selected from the group consisting of liquid polymeric latexes and dried polymeric latex solids;
- (c) about 0.01 to 10 parts by weight of a water soluble polysaccharide compound selected from the group consisting of starch esters and ethers;
- (d) about 0 to 90 parts by weight of a filler;
- and
- (e) a sufficient amount of water to form a smooth, moist, evenly-consistent composition;
- wherein the components are combined to form composition having about 100 parts by weight exclusive of water.
