Recommended grouts

It is important to use a grout appropriate for the use to which the ceramic surface will be put.
You should follow the instructions provided by leading grout manufacturers.


Use and recommended grouts according to european standards EN 13888:

  • residential interiors: improved cementitious mortars for joints (Class CG2 - EN 13888)
  • damp interiors (bathrooms, showers, swimming pools, etc.) and outdoors: improved cementitious mortars for joints with low water absorption (Class CG2 W - EN 13888) obtained with the addition of a suitable liquid additive;
  • commercial premises: improved cementitious mortars for joints with high resistance to abrasion (Class CG2 Ar - EN 13888) obtained with the addition of a suitable liquid additive;
  • premises requiring total hygiene and resistance to chemical agents (kitchen work surfaces, food industry, hospitals, supermarkets, etc.): epoxy mortars (Class RG - EN 13888).

Eliminating excess grout

To correctly and easily eliminate excess grout, follow the instructions given by the grout manufacturer. In general, proceed as follows:

  • cementitious grouts: when the grout becomes opaque (normally after 10-20 minutes), clean with a hard cellulose sponge using movements on a diagonal to the joints. It is important to respect the drying time to avoid removing the grout from the joints.
  • epoxy grouts: when the mixture is still fresh, wet the surface with plenty of water, emulsifying with a Scotch-Brite® pad, paying attention not to empty the joints. The residual grout liquid can be removed with a hard cellulose sponge (to be replaced when excessively soaked with resin).
    It is vital to remove epoxy grout rapidly before it starts hardening as it is extremely difficult to remove subsequently. If the epoxy grout has started to harden, try adding 10% alcohol to the washing water.
