Ceramic Tile Underlay

Cemintel’s Ceramic Tile Underlay is for internal use and is an easily installed and cost effective way to form a flat substrate for laying ceramic tiles over existing floors.

It provides a thinner solution for tile substrate that minimises the impact on floor levels with surrounding areas. It is an effective option to use over tongue and groove hardwood floors when tiling over them.
