Remedial
The problem must be arrest at its source before attempting any repair of plastering on an already deteriorated background. The source for water penetration should be traced and the cracks should be made good.
The process follows:
- A dry brush or high pressure water jets can be used to abrade off any salts that are present on the background surface.
- With the removal of the salts, apply bonding treatment to the wall surface before re-plastering the background making sure that the colour and texture of the new plastering closely matches that of the existing work.
- Repainting must be done as the paint coat may be washed off in the process.
