Decorative mineral coating for interiors and exteriors
Calcecruda Intonachino is formulated on the specific properties of lime hydrate, purified clay, selected marbles and natural sands, which when appropriately balanced, allow excellent workability and moldability.
The clay component creates a network structure of particles, adjusts processing times and improves the workability of the product.
The presence of cellulose fibres strengthens and reinforces the structure, thus contributing to the realisation of greater thicknesses – 1.5-2 mm – in synergy with the other components.
Calcecruda Intonachino allows the attainment of top-quality finishes with crinkled effect, with soft and warm colours, at the same time providing an elegant decoration for interior and exterior surfaces.
Calcecruda Intonachino sensitively reduce the formaldehyde concentration, as per the specific law ISO 16000-23. The duration of the destruction process is not permanent, it is strictly linked to the environmental conditions.
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 in the presence of 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 deposits, smog and other by brushing. In the presence of non-cohesive and crumbling substrates, apply a layer of Decofix (micronized wall primer) using a brush.
- Alternatively, for solid, non-crumbling substrates, a layer of diluted Novaprimer (water-based pigmented acrylic sealer) can be applied using a brush.
- Using a stainless steel spatula, apply a smooth layer of Calcecruda Intonachino onto a completely dry surface and before the latter dries totally, finish the surface using a damp sponge trowel.
- Drying time: approx. 24 hours depending on the type of substrate, its absorption and the environmental conditions.
- Calcecruda Intonachino can be applied on exterior surfaces only if it will be covered with at least 2 layers of Fase Silossanica or Patina Minerale. It is advisable to apply a first layer of clear color wash and complete the decoration/protection of the surface with one or more layers of tinted color wash.
May also be applied over:
- New and old base hydraulic binder-based plaster.
- Old paints and organic or mineral coatings, dry, compact, absorbent and cohesive.
- Various absorbent mineral conglomerates.
- Gypsum and plasterboard surfaces
Approximate coverage yields 2.2-2.8 kg/m2 in one layer, according to the finish of the substrate and its absorption.
It is good practice to check the effective coverage via a preliminary test on the specific substrate.
