Alkyd and oil-based paints react and saponify with alkalis present in new masonry to form water-soluble soaps. The paint film turned into soap, becomes soft, sticky, and water-soluble.
Possible Cause:
- Incorrect use of product
- Application of Alkyd-based (oil) paints to alkaline material (e.g. concrete or cement.)
- Humidity problems.
- Caustic stripped surface not neutralized.
Solution:
- Remove all paint layers.
- Prevent water penetration.
- Apply an alkali resistant coating.
