Cause:

• Use of water-based paint over multiple coats of old solvent-based paint causes the old paint to “life off” the surface.

Prevention

• Avoid incompatible materials such as a thinner with enamel products, or imcompatible sealers and primers.
• Allow sufficient flash and dry time.
• Select the correct thinner and diluter specified on the Technical Data Sheet.
• Solvent test and remove solvent-sensitive substrates.
• Avoid excessive film thickness.
