Tile substrate over green masonry or existing/mixed substrates
Uneven substrates
Schlüter-KERDI-BOARD is ideal for installation on:
- Concrete.
- Masonry of all kinds.
- Existing substrates such as plaster,
tiles, painted surfaces, etc.
- Mixed substrates.
To be suitable for the installation of tiles in the thin-bed method with tile adhesive the substrate must be completely level and made of an appropriate, moisture resistant material. However, walls are frequently covered with a gypsum plaster coating as part of construction. Plaster is not a suitable substrate for tile coverings, especially in high moisture areas. Additionally, these surfaces are typically not level enough. Other materials such as drywall panels or wood composite are equally unsatisfactory in these areas.
