Description Loss of adhesion where many old coats of alkyd or oil-based paint receive a latex topcoat.
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 due to the tight bond of the latex film when it dries.
Oil paint applied over latex can crack and peel because it may not have the ability to flex and breathe iike the latex coating underneath. Oil paints dry hard and are relatively non-flexible.
