SCALP ANTI-SALPÊTRE, film-forming protection against saltpetre, has a triple-action formula :
- Waterproofing: it stops damp on surfaces that generate saltpetre
- Strengthening: it hardens and solidifies the surface
- Bactericidal and algicidal: it destroys nitrifying bacteria
SCALP ANTI-SALPÊTRE is applied to a clean surface prior to painting, wallpapering etc. Its transparent, film-forming finish means that it does not need to be painted over or coated if you so choose.
Prepare the support by removing the various coatings such as paint, wallpaper, etc. from the degraded surface.
Remove with a brush the effloresence.
Mix well SCALP ANTI-SALPÊTRE.
Apply from the base upwards until the surface is saturated on two coats at 15mn intervals.
Wait 48h before putting a new coating or a paint.
