Provides a smooth, permanent finish to a variety of substrates prior to the installation of today’s demanding floor coverings such as sheet vinyl and VCT. ARDEX SD-F allows the installation of most floor covering in as little asl5 minutes over concrete, wood, ceramic, and quarry tile - all without priming or the use of a latex additive. Engineered around a selfdrying, Portland cement-based matrix, all of the water is chemically combined within the product itself. Using this unique technology, flooring installation problems associated with disbonding, crumbling, mildew, and staining are eliminated, thus preserving the floor manufacturer’s full product warranty. 10 lb. unit covers up to 33.3 sq. ft. at 1/8”. When skimming over concrete, coverage is 100 150 sq. ft., and over plywood, 200-250 sq. ft. can be achieved.
