Just found out my house was painted with DOWSIL?
basically the title. previous owner 20 years ago stopped by tonight and sells DOWSIL silicone elastomeric coating. he says they painted the house and foundation with it 19 years ago.
The house is peeling like crazy, so we’re working on scraping and priming. he was basically offering to sell us some more DOWSIL. he said that paint won’t stick to the silicone coating unless we totally scrape all the paint off. so…what now?
do I have to buy more of this silicone stuff?
Should we just scrape down to the wood? see photo 1. We scraped a decent amount of it on the one side (photo 2) and the unprimed side is even worse than the primed side was. Only 2 side of the house need paint currently so we’re trying to do it ourselves.
also - who even does this? is this a thing?
