Paint Incompatibility
Definition
Loss of adhesion when a water-based topcoat is applied over many old coats of oil-based paint.
Causes
- Use of water-based paint over multiple coats of old oil-based paint causes the old paint to “lift off” the surface
Solutions
- Remove all loose paint down to the bare surface. If you’re using liquid removers, be sure to wear long sleeves and gloves to protect your arms and hands from splashes.
- Prime any bare surface with a high-quality primer and allow it to dry thoroughly.
- Paint with a high-quality paint in the desired finish.
