Silicate colour wash for indoor and outdoor mineral substrates
Patina Minerale is a transparent vehicle, with colloidal silica base, appropriately modified with organic binders and special waterrepellents.
Patina Minerale is ideal on mineral substrates such as CalceCruda.
The chromatic effect resembles the antique colour washes typical of the mineral systems, with the possibility of obtaining tones and shades of colour on the basis of the techniques and the colours applied.
The particular formulation of Patina Minerale allows high vapour permeability to be obtained, associated with good resistance to UV rays and atmospheric agents.
Patina Minerale represents the expression of Novacolor “Green Approach”. To reduce the “carbon footprint”, Patina Minerale is formulated with a special binder. Based on a “mass balance approach” fossil raw materials in production are replaced with sustainable biomass.
Patina Minerale represents the expression of Novacolor commitment to the environmental sustainability. To reduce the “carbon footprint”, Patina Minerale is formulated with a special binder, made from sustainable biomass, that replaces the fossil raw materials.
This is possible thanks to a technical-productive system called “mass balance approach” certified REDcert².
Application:
- The surface must be dry and have no dust and mineral salt spots. If necessary, restore or consolidate the substrate using specific
products. - Treat the surface with appropriate products if there is any mould. Remove any salt bloom and any flaking old paint by brushing or washing.
- Completely eliminate any raised layers of lime-based or tempera paint. Remove the dust, smog or other deposits by brushing.
- In the presence of non-cohesive and crumbling substrates, apply a layer of Decofix (micronized wall primer) using a brush. For solid, non-crumbling substrates, a layer of diluted Acricolor (acrylic water based sealer) or Novaprimer (water-based pigmented acrylic sealer) can be applied using a brush.
- Wait for the base coat to dry completely and apply a layer of diluted Patina Minerale using a sponge or woollen glove; work the surface depending on the effect desired.
- For aesthetic or site reasons, a second layer of Patina Minerale can be applied as described above.
- Drying time: approx. 24 hours depending on the type of substrate, its absorption and the environmental conditions.
- Pay attention to the different degree of absorption and roughness of the surface; it may vary the perception of the colour.
Applicable to mineral substrates:
- New and old hydraulic binder-based plaster.
- Old paints and mineral coatings, dry, compact, absorbent and cohesive.
- Various absorbent mineral conglomerates.
Not applicable on:
- Old organic paints (washable or quartz-based paints).
- Concrete surfaces because, owing to its high permeability, the product has no protective power against the aggression of carbon dioxide; the main cause of degradation of concrete.
Patina Minerale (dil. 20%): 4-8 m2/l, in the two layers, depending on the type of substrate, its absorption and effect created.
Patina Minerale (dil.300%): 12-15 m2/l, for each layer, depending on the type of substrate, its absorption and effect created.
It is advisable to check the effective coverage via a preliminary test on the specific substrate.
