Lime-based key coat in powder for interiors
Archi+ Fondo is a mineral base coat in powder, formulated for the preparation of substrates where Archi+ product range will be applied on.
Archi+ Fondo can be applied both indoor and outdoor. It is made of hydrated lime, white cement, aggregates and rheological modifiers carefully selected to ensure an excellent workability.
Application:
- The substrate must be perfectly dry, dust-free, with no humidity and salt stains.
- Remove any traces of disarming.
- Remove with mechanic drill or high-pressure washing detaching parts or traces of dirt. Level any irregularities in the surface and treat holes, cracks, cervices and gaps in indoor with specific products. Wait for the complete maturation of the substrate before to start the application.
- On dry and compact substrate, apply with brush a layer of Decofix (micronized clear sealer) properly diluted.
- Wait few hours, then apply one coat of Archi+ Fondo with stainless steel trowel levelling the surface properly. Remove any imperfection or any exceeding amount of product. Apply a second layer of Archi+ Fondo is necessary.
- Drying time: 24 hours approx depending on the type of substrate and the weather conditions.
May also be applied over:
- New or pre-tinted mineral plasters
- Mineral or cement-based mortars
- Various mineral and absorbent conglomerates
- Pre-fabricated panels
Approximate coverage yields 0.8-1.0 Kg/m2 (ref. to the paste) and 0.5-0.7 Kg/m2 (ref. to the powder), per layer, depending on the type of the substrate and its absorption rate. It is suggested to test the effective yield directly at site.
