Bostik® UltraFinish is a fast-setting, latex-fortified, Portland cement-based patch for interior use prior to installation of hardwood, ceramic, carpet, vinyl or rubber flooring. UltraFinish contains Bostik’s Blocade™ Antimicrobial Protection, which inhibits growth of bacteria, mold, or mildew on the surface of the dried cement; the cement resists stains caused by mold.
