Silicate-based breathable water paint for indoor

Mural water paint for indoor usage, washable and highly breathable, with good coverage, mat look. Thanks to its special formula based on potassium silicate resin (DIN 18363 certified), gives high transpirability to the support, making it suitable for resanation and restoration of historical centres.


Fields of application

Thanks to its diffusive and vapor-stable features, it is used for decoration and protection on environments affected by rising damp.

Applicable on any type of indoor support, properly prepared:

  • Smoothing products
  • Consistent paints and coatings
  • Fine plasters
  • Supports subjected to resanation
Support preparation

On old walls: Proceed to consolidation and resanation of the support with specific products depending on the surface condition. Before proceeding to finishing, make sure the support is perfectly dry and cured.

On new walls: Sand and dust out perfectly.

Pre-treated walls: Sand and dust out if in good conditions. In bad conditions, carefully remove any previous detaching paint, fill any possible hole and crack, let dry, sand and dust out perfectly. In the presence of mold treat the surface with PRO 01 and PRO 02.
