| Paint Incompatibility: Loss of adhesion where many
old coats of alkyd or oil-based paint receive a latex top coat.
Possible Cause:
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.
