@diyjorge: This issue has nothing to do with sanding👇 Latex paint doesn’t bond over oil based paint without priming beforehand. If your current or old paint is oil based, then either you go over it with oil based paint again or you prime with oil based primer, sand and then apply your latex paint. This video is a prime example of using the wrong paint but I give you 2 different methods to figure out the right paint to use. Hope it helps! #painting #housepainting #tipsandtricks #construction #badpaint #DIY #doityourself #fyp #exteriorpainting #sherwinwilliams #rubbingalcohol #oilbasedpaint #latexpaint #paintingtips
