Schluter®-DITRA and DITRA-XL are specifically designed for ceramic and stone tile installations. DITRA and DITRA-XL provide uncoupling to prevent cracked tile and grout. Made of polyethylene, DITRA and DITRA-XL serve as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB. Free-space on the underside of the matting provides a route for excess moisture and vapor to prevent damage to the tile layer above. DITRA and DITRA-XL perform all these functions while still providing adequate support/load distribution for the tile covering. Provides uncoupling, waterproofing, vapor management, and heavy load distribution to ensure the durability and integrity of tile installations Quick and easy to install on top of concrete, plywood, OSB, gypsum, existing vinyl floors, structural planks, sub-floors, and radiant heated floors Convenient tile underlayment alternative to cement backer board or plywood Use DITRA for ceramic tile installations over single layer plywood or OSB subfloors on joists spaced up to 19.2" o.c. DITRA is only 1/8" (3.5 mm)-thick to provide the thinnest possible assembly without sacrificing performance DITRA features cutting grooves for precise cuts and air release vents at the corners of the cutback cavities for faster filling Use DITRA-XL for ceramic tile installations over single layer plywood or OSB subfloors on joists spaced up to 24" o.c. DITRA-XL is 5/16” (7 mm)-thick to create an even transition between typical 5/16” (7 mm)-thick tile and 3/4” (19 mm)-thick hardwood flooring DITRA-XL is ideal for installations requiring greater movement accommodation, such as applications using natural stone tile, large-format tile, etc. DITRA and DITRA-XL are for interior use only, dry or wet areas
