Anti-saltpetre
SCALP ANTI-SALPÊTRE is a professional solution designed to permanently remove saltpeter from walls and prevent its reappearance. Thanks to its triple-action formula, this treatment combines water-repellent, consolidating, and bactericidal properties to thoroughly clean wall surfaces, whether they are made of concrete, brick, stone, or plaster.
Saltpeter, caused by capillary action and the presence of nitrates in materials, weakens the solidity of walls and prevents any durable finish (paint, wallpaper, decorative plaster) from adhering. SCALP ANTI-SALPÊTRE acts effectively on the causes of the phenomenon
- It blocks moisture on the surface thanks to its water-repellent properties.
- It hardens and stabilizes weakened surfaces.
- It neutralizes the nitrifying bacteria responsible for the formation of saltpeter.
This treatment is ideal before any renovation or wall decoration: it ensures a healthy, stable, and durable surface, ready to receive a finish without risk of peeling or deterioration.
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.
What are anti-scalp products ?
Anti-saltpetre products are specific treatments designed to eliminate and prevent the saline efflorescence that appears on walls as a result of dampness, particularly in cases of capillary rise or poor ventilation. These whitish traces, unsightly and sometimes destructive, are the sign of an accumulation of mineral salts (nitrates, chlorides, sulfates) on the surface of materials.
The main aim of anti-salt products is to neutralize these salts, sanitize contaminated substrates (stone, brick, concrete, plaster, etc.) and prevent further migration to the surface. Some treatments also have a water-repellent or consolidating action to durably strengthen materials exposed to humidity.
When and how to apply an anti-saltpetre treatment ?
The application of an anti-saltpetre product is recommended in several cases:
- On interior or exterior walls showing white marks, visible signs of salt
- After a capillary rise treatment, to neutralize salts already present in the
- In preparation for a renovation project, before applying plaster, paint or
The product must be applied to a dry, clean and sound substrate. Prior cleaning with a suitable detergent or anti-foam treatment may be necessary in the event of biological contamination or soiling.
SCALP anti-window products are generally applied by brush, roller or spray, depending on the substrate configuration. They have an in-depth effect, without altering the appearance of the treated material.
Can an anti-saltpetre treatment be combined with other products ?
Yes, the use of an anti-saltpetre product is often complementary to other treatments:
- After treatment, it's advisable to apply a water repellent to prevent moisture from penetrating the substrate again and restarting the salt crystallization process.
- It is also possible to apply a finish coating or microporous paint to a treated substrate, provided that drying times are respected.
