Anti-Efflorescence Treatment
Salt-blocking primer for plastered walls
Applications
White salt patchesPeeling paint band near the floorFresh alkaline plasterMasonry and brick
Procedure
- Stop the moisture source and let the wall dry.
- Scrape off blistered paint, soft putty and any powdery skin.
- Brush the salt off dry and collect it. Do not wash the wall.
- Tap the plaster. If it is hollow or crumbling, replaster instead of priming.
- Apply two coats of RAPIDSTRONG SALT FLUSHER on the clean, dry surface.
- Finish with the chosen paint.
Important Suggestions
Washing dissolves the salt and carries it back into the plaster, from where it comes out again.
Why This Treatment?
RAPIDSTRONG SALT FLUSHER forms a physical barrier to water and a chemical barrier to salt migration, so salt cannot push through the new paint.
