ROBERTS 2057 Vinyl Composition Tile (VCT) Adhesive is a clear, solvent-free, water-based, thin-spread adhesive that provides excellent grab and high residual tack. This superior grade adhesive brushes, rolls or trowels on and helps hold tiles firmly in place, even when subjected to repeated cleaning and mopping. When spread thinly as instructed, the adhesive dries correctly and turns clear, allowing chalk lines to remain visible. This adhesive is also suitable for installing vinyl-composition or vinyl-asphalt tile over existing vinyl-composition or vinyl-asphalt subfloors that are free from waxes, sealers and finishes.
