The Idaho Painter Live Q&A on Interior and Exterior Painting

What happens here

A viewer asks how to address mold on a whitewashed tongue and groove patio ceiling in Florida. The presenter advises against simply covering the mold. The first step should be to kill the mold using a bleach solution (e.g., 25% bleach). After killing the mold, a clear coat should be applied to prevent future mold growth. He specifically recommends Helmsman water-based spar urethane, which does not yellow and is easy to use. He suggests spraying and back-brushing for best results.
