ECO-CAL is a Biocompatible Eco Plaster, pre-packaged powder for interior and exterior use according to UNI EN 998-1. ECO-CAL is totally free of cement and compounds belonging to the clinker group. It is made up of a mixture of pure silicone calcareous sands with a continuous grain size arc from 0 to 1.4 mm. The only present binder is the St ASTIER Pure Natural Hydraulic Lime NHL5 according to UNI EN 459-1. The lime NHL 5, white, is produced by baking siliceous limestones at temperatures below 1250°C and reduced in powder by only the break down of calcium oxide, without the addition of pozzolanic materials or hydraulic binders of any kind.
ECO-CAL is a pre-packaged powder, biocompatible, free of salts, chemical products and volatile organic compound (VOCs) plaster. These features, combined with the total mineral nature of the components, guarantee the purity, non-toxicity, non-harmfulness and the total recyclability of the product in full respect for man and the environment. The use of ECO-CAL makes the plasters eco-friendly, biocompatible and reversible, giving high breathability to the substrate on which it is applied, avoiding the formation of dangerous condensation and bacterial proliferation by regulating the ambient humidity and carbon dioxide content of the environments.
