CALCHÈRA Rasatura is FINE MARMORINO (or GRASSELLO)
suitable for creating the very smooth, glossy translucid finishes known as “calce rasata”.
Can be applied in 2 or 3 (for best result) coats.
20 KG bucket (4 Gal) will cover 250SF with 3 coats application system.
It has a base of lime paste, coloring earths, marble powder, vegetable additives. After application it reacts with the carbon dioxide present in the environment, giving rise to micro-crystalline calcium carbonate. In addition, reacting at the same time with the calcium salts of the plaster, this product gives rise to calcium carbonate, a mineral with chemical-physical characteristics resembling those of building materials. CALCHÈRA Rasatura presents an excellent adhesion on mineral surfaces based on lime mortar or cement-lime mortal, even if seasoned. The vapour permeability of CALCHÈRA Rasatura is very good, insofar as the micro crystalline structure resulting from the precipitation of calcium carbonate does not modify the porosity of the plaster. Thanks to the high degree of alkalinity deriving from the inorganic nature of coating,CALCHÈRA Rasatura is particularly resistant to mold and fungi. To these peculiar characteristics CALCHÈRA Rasatura adds chromatic effects of great elegance similar to those of color finishes of the past.
