Causes: - insufficient drying time between coats - hard coating over a soft primer - multiple coats of naturally aged oil based paints that are brittle and begin to crack - the inability of the top coat to bond to the under coat Solutions: - remove all the old paint by scraping and sanding (use a power washer for large areas to shorten removal time) - to avoid alligatoring in the future properly prepare the surface and paint with a high quality primer/finish coat |
