The exterior paint on my 1920’s Craftsman is quite uneven, probably due to a past owner scraping without sanding, and painting over it. A painter that we hired began work by scraping away chipped paint, applying a white plaster-like substance, letting it dry, and sanding it smooth. It seems OK so far, but I did not see you discuss that technique on your (great) website. Is that a proper technique? If so, what is the right way to do it? Thanks!
