Latex paint peels due to poor wall preparation, air or wall moisture, incompatible paint types and poor paint quality. The loss of adhesion between the surface and the latex paint causes bubbles or blisters that lead to peeling.
It is essential that walls receive a coat of primer and sealer prior to painting, and this step is doubly necessary when latex paint covers an existing oil-based paint. Benjamin Moore recommends applying paint when the humidity is low and the walls are cool. Installing vents or exhaust fans reduces the overall humidity within a house. Poor quality paint tends to peel easily, as it lacks adhesive properties.
