Anti-algae acrylic-siloxane fine plaster coating for exteriors
Concrete By Novacolor is an anti-algae acrylic-siloxane plaster coating for exteriors, fine grain (0,5-0,7 mm).
The particular grain curve of Concrete By Novacolor and the possibility to overlap it with one or more layers of Fase Silossanica, acryl-siloxane colour wash (matt), ensures to achieve cutting-edge elegant concrete effects, in line with the newest trends in the interior design.
Application:
- The substrate must be perfectly dry, dust-free, with no humidity and salt stains.
- Resurface or consolidate the surface with specific products if necessary.
- In case of mould, treat the surface with suitable specific products.
- Brush or remove any efflorescence and old peeling paint.
- Higher layers of old lime-based paint and tempera paint must be removed.
- Brush out dust, smog or other deposits before the application.
- In case of non-homogeneous or chalky surfaces, apply one layer of Decofix (micronized wall sealer) diluted, with a brush.
- In case of compact and non-chalky substrates, it is possible to apply Acricolor (coloured highly permeable water-based siloxane rimer) diluted, with a brush.
- Once the substrate is completely dry, apply one coat of Concrete By Novacolor with a stainless steel or plastic trowel.
- Remove any imperfections and/or any exceeding amount of product.
- Once the first layer is completely dry, apply a second coat of Concrete By Novacolor until you will obtain a homogeneous surface.
- Work into the product still wet with the specific “trowel for Archi+ Concrete” until reaching the desired texture typical of the product.
- Wait the product starts to set (partially dry) before smoothing it down with a stainless still trowel.
- It is possible to enhance the post-industrial concrete look applying one or two layers of Fase Silossanica with sponge, on dry surface.
- Apply the first layer of Fase Silossanica, diluted, with a clean and dry sea sponge.
- Remove the exceeding products, working the surface with a clean and dry sponge.
- When the substrate has dried out totally, apply a second coat of Fase Silossanica following the same procedures.
- Drying time: 48 hours approx. depending on the type of substrate, its absorption rate and weather conditions.
May also be applied over:
- New renderings or old plasters
- Concrete surfaces
- Old paints or dry, compact, absorbent, mineral coatings
- Various absorbent mineral substrates
- Insulating systems
- Plasterboards
Approximate coverage yields 1.6-2.0 kg/m2 in two coats, depending on the kind of substrate
