Paint Incompatibility

Paint IncompatibilityLoss of adhesion where many old coats of alkyd or oil-based paint receive a latex top coat.

Possible Causes:

  • Use of water-based latex paint over more than three or four coats of old alkyd or oil-based paint may cause the old paint to "lift off" the substrate.

Solution:

  • Repaint using another coat of alkyd or oil-based paint. Or completely remove the existing paint and prepare the surface - cleaning, sanding and spot-priming where necessary - before repainting with a top quality latex exterior paint.
