I stained our log house 7-8 years ago with Cabot’s semi-solid oil-based stain. I just had it powerwashed and I am considering going to a water-based stain because the oil-based stuff seems to mildew very quickly these days. My painter feels that there shouldn’t be much of a problem with changing to water-based. Do you agree? Also, was wondering if you have any experience with the Ben Moore or Sherwin Williams water based semi-solid stains..
