BEFORE GROUTING
To avoid problems with grouting residuals on high porous materials like handmade terracotta, porous sandstones, white or sandblasted limestone etc..
we recommend using the product PRESTUCCO. This product should be applied after laying and before grouting.

It makes the cleaning of grouting residues easier and also the final cleaning will be easy and effective.
With 1 litre you can treat about 15-20 sqm. Evenly apply by spray-gun on the whole surface before grouting.
Allow to dry at least 3 – 4 hours. It does not create problems, since it is compatible with the following protective treatments.
