Tarkodry floor and wall underlayer is a glue-down homogeneous PVC underlayer that is especially designed to create waterproofness in wet room areas. Tarkodry is a safe and long-lasting solution that can be installed under ceramic tiles and provides good adhesion thanks to its embossed structure. It also has a flexible homogeneous structure, which makes installation and welding easier. Tarkodry can be installed over cement substrates or cardboard dressed plaster, and is compatible with ceramic tiles.
