Substrate For Tiles

When it comes to tiling, no matter what you’re fixing, it’s important to properly prepare your surface to ensure a professional finish and a strong bond. Schlüter®-KERDI-BOARD is manufactured using new technology with a special focus on the practical requirements of construction sites and offers flexibility for a range of installation and design purposes.

What is a tile substrate?

A tile substrate is simply a base to which your tiles are fixed with tile adhesive. This is placed level against a wall, and helps to provide a flat surface for an even finish.

A purposely made tile substrate such as Schlüter®-KERDI-BOARD has been specifically designed to withstand the demands of installation and use. Not only is it suitable for use on any kind of background substrate, it’s also lightweight, easy to handle and transport. KERDI-BOARD is waterproof and temperature resistant, along with having many other benefits.



Schlüter®-KERDI-BOARD is a universal substrate for the installation of tiles on walls of any kind and can also be used in bonded waterproofing assemblies. Schlüter®-KERDI-BOARD is suitable as an underlayment for filler or plaster coatings.
