Recently I came across what is known as alligatoring paint on wood siding. I thought the problem might have been due to using the wrong type of paint but a quick call to Pat at Border Paint soon cleared up the real issue. Pat said that what happens is that after many coats of paint are applied over the years the base or primer coat will crack and the process of alligatoring begins. The only way to stop the process is to get about 90% of the old paint off the wall using a sander or scraper. If the siding is cedar he said you can also apply an oil based primer/sealer. Then you can use latex paint over the sealer. For more paint related questions call Pat at 780-875-3120.
