Mineral plaster coat in powder for interiors, formulated with natural clay
Archi+ Argilla is a powdered mineral wall coating for interior use, based on clay, aerial lime, carefully selected aggregates and rheological modifiers to ensure excellent workability. A new product formulated with natural clay, which confirms Novacolor’s green approach and sustainable innovation. An historical raw material such as clay, combined with modern technologies, finds the maximum expression within Archi+ range, the collection of powder-form mineral plasters for prestigious interiors. Thanks to its composition, Archi+ Argilla can be applied in one layer on new and old plasters made of hydraulic binders, plaster and plasterboard surfaces, organic or mineral paints and coatings, and absorbent mineral conglomerates.
Application
- The surface must be completely smooth, dry and free of dust, and of humidity-salt stains.
- Remove any traces of release agent.
- Remove (mechanically with hand tools or with high-pressure hydro washing) the degraded or detaching parts, dirt residues.
- Protect the exposed reinforcement rods and refill hollows with appropriate non-shrinking mortars. Before application, wait for the backgrounds to dry fully.
- One or two coats of Archi+ Fondo (base coat plaster) can be applied to prepare the background.
- Once the background is dry and compact, use a brush to apply one diluted coat of Decofix (micronized wall fixative).
- For consistent, non-flaking backgrounds, as an alternative, use a brush to apply a coat of diluted Novaprimer (water-based
pigmented acrylic fixative). - Wait for the background to dry fully, then use a stainless steel trowel to apply a layer of Archi+ Argilla. Work on the surface while it is still wet, depending on the desired aesthetic effect.
- For aesthetic or building-site requirements, it is possible to apply a second layer of Archi+ Argilla, following the methods described above.
May also be applied over:
- New and old plasters based on hydraulic binders.
- Gypsum and gypsumboard surfaces
- Old paints and coatings of organic or mineral nature, dry, compact absorbent and cohesive.
- Conglomerates of various minerals as long as they are absorbent.
Approximate coverage yields 1.8-2.2 kg/m2, for each coat depending on the type of background and its absorption rate. We recommend checking actual yield by making a preliminary test on the specific background.
