Where saponification has occurred to the extent that the soapy solution appears, it can easily be removed by washing with water because the saponified oil is in fact water soluble.
Where the effect is not so severe & has merely soften the film, a strong solvent such as xyol, acetone will soften the paint further to the stage where it can be stripped off.
The affected areas should be allowed to dry out thoroughly and a coat of alkali resistant cement sealer applied prior to finishing in the usual manner.
Repainting
- Remove loose and flaking paint with a scraper or wire brush, sanding the surface and feathering the edges. If the flaking occurs in multiple layers of paint, use of a filler may be necessary.
- Surface should be cleaned before applying the paint.
- Use of a top quality primer and top coat should prevent a recurrence of the problem.
- Refer to “Good Practice” section for details and instructions of painting process.
