SCALP NDS 72
SCALP NDS 72 is a highly effective surface treatment designed to remove efflorescence (whitish salts) and neutralize alkaline residues after cleaning or stripping. Thanks to its powerful acidic formula, this impregnation product ensures fast and long-lasting action, guaranteeing perfectly prepared surfaces before finishing.
Efflorescence is caused by the migration of mineral salts to the surface of porous materials (bricks, concrete, plaster, stone, etc.) in the presence of moisture. It results in whitish deposits that detract from the appearance and adhesion of finishes. SCALP NDS 72 acts deep down to dissolve these salts and prevent them from reappearing.
