Fixing porcelain stoneware

Porcelain stoneware is a very low water absorption ceramic tile, which is dry pressed with a wide range of colours and it is fired only once.

Thanks to its exception hardness and resistance, it is used on pavements as renders, ranging from conventional bathroom and kitchen coatings to more difficult arrangements on façades and high transit pavements.

To ensure that it is attached correctly to the substrate, an adhesive mortar with mixed binding agents has to be used, that is, which also contains resin as well as cementand provides the appropriate chemical adhesion.

Solution

PREPARING THE SUPPORT

Check that the support is strong, perfectly set and clean of any dust, paint, oil….

Wet the support if it is exposed to sunshine and/or if it has to be very absorbent.

Check the smoothness of the support with a 2 m long ruler; any differences must be less than 5 mm.
