Alligatoring probable causes - usually multiple coats of naturally aged oil based paints that have become brittle and start cracking. Topcoat's inability to bond smoothly to a glossy undercoat. Insufficient drying time between coats. A hard coating over a soft primer.
Alligatoring solutions - remove all of the old paint by scraping and sanding. A power washer is recommended for large areas to shorten the removal time. The best way to avoid future alligatoring is to properly prepare the surface and paint with a high quality primer/finish coat.
Primers and Exterior Finishes - Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Ask your Muralo dealer for the best Muralo exterior paint for your project, in the color and sheen of your choice.
