Check of substrates
The completed tiled covering is only as good as the substrate allows. Therefore, check the substrate carefully and prepare it for tile fixing. The substrate must be dimensionally accurate and technically suitable in order to allow a flawless ceramic covering on it. Dimensionally accurate means sufficiently level, flush, horizontal or with the planned slope. Technically suitable means load-bearing, clean, dry, dimensionally stable and free of adhesion-impairing particles. The tests described here are intended to assess the installation substrate in order to select a suitable substrate pre-treatment.
