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. |
