PITTURA AI SILICATI
Water - based paint based on potassium silicate
High water vapour permeability
Excellent adhesion to the substrate
Code
0827
Description
It is a water - based paint based on modified potassium silicate, selected charges and pigments resistant to natural light.
Potassium silicate reacts with carbon dioxide in the air to produce a strongly alkaline chemical reaction called silication.
This chemical process leads to the consolidation of the substrate down to its depth, thus eliminating the phenomenon of flaking.
In addition, the considerable increase in alkalinity creates a favourable environment for the anticorrosive protection of the metal reinforcements, if present, and preserves the substrate from mould formation.
Once dry, it creates a film - free coating with high water vapour permeability, excellent resistance to ageing, excellent resistance to weather, good resistance to temperature variations and very low dirt retention.

Use
Painting with silicate paints is particularly recommended for historic buildings and new constructions with untreated plaster both for the interior and for the exterior and where excellent resistance to weather and high water vapour permeability are required.
Its final aesthetic appearance is very pleasant and natural with slight colour nuances. It is only applied to mineral plasters or plaster surfaces.

Preparation of surfaces
Plasters:
Make sure that the substrate has passed a curing time of 28 days and that its humidity is less than 10 %.
Remove any efflorescence by washing and brushing.
Old paintings should be completely removed.
Any levelling or remakes must be carried out with mortars that are compatible with potassium silicate (pre - mixed plasters, lime, concrete).
If mould is present, carry out an appropriate healing treatment.

Environmental conditions
Ambient temperature: from + 15 to 30° C
Temperature of the substrate: > 10° C
Humidity: 0 - 75 %
In order to prevent the formation of condensation, it is necessary that the temperature of the substrate is at least 3° C above the dew point.
Avoid application with excessive condensation or under direct sunlight.
