Description
Pro Mastic 400 Premium Ceramic Tile Adhesive is a professional formula adhesive with great bond strength. Ideal for small format ceramic, mosaic, porcelain and most gauged stone tile on walls and floors, Pro Mastic 400 is used in areas with intermittent water exposure like tub surrounds and shower walls. Recommended for tile up to 8" (20 cm) on any side. Can be used with wall or countertop tile up to 15" (38 cm) on any side but dry time significantly increases. For tile with any side greater than 15" (38 cm) MERKRETE recommends using a polymer modified LHT mortar for setting large and heavy tile.
