PROBLEM SOLVER – PAINT INCOMPATIBILITY
Paint Incompatibility results in the loss 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.
