Lack of adhesion of a
topcoat causing peeling down to a hard, slick surface.
Hard, slick surfaces are
prone to peeling because adhesion is difficult to achieve. The surface
offers no peaks or valleys for the coating to “bite” into.
Prior to painting, wash all
surfaces using a mild deter-gent and sponge to remove any grease, oil, wax
or other surface contaminants. All glossy surfaces should be dulled by
sanding or wiping down with a deglosser. If the old surface is still hard
and slick, an appropriate bonding undercoat should be applied to provide a
perfect base for the final coat of latex. For heavy duty needs, a quality
alkyd enamel is preferable to a latex topcoat. It is still important to
allow enough time for curing even with the best preparation and application.
