Archi+ Pietra is a mineral plaster coat in powder for interiors. It is made of natural hydraulic lime NHL 3,5 (EN 459-1), aerial lime, specific aggregates and rheological modifiers carefully selected to ensure an excellent workability. The particular formulation allows the attainment of top quality finishes. For the protection of the surfaces decorated with Archi+ Pietra, two different solutions are available: Non film forming protection: recommended wherever a good resistance to water and various soluble hydro and oleo substancesis required. It can be done by applying two or more layers of Nova_Wall Care (hydro-oleo-repellent wax), that protects the surface without modifying the aesthetic aspect. It is the classic solution for this kind of finishes. Film forming protection: it is recommended in all cases where you want to achieve a valid surface protection against cold liquids, dry heat and humid heat. It is achievable by applying a layer of Mineral Sealer (bi-component primer) and two layers of one of the Clear Finish Countertop Protection finishes (bi-component finish).
