Q: We’re installing pine wood floors. Should we use a sealer after it’s sanded, but before it’s stained? If so, what sealer do you recommend that will allow proper absorption of the stain?
A: I never use those sealers. With soft wood in particular you need to work at a steady rate and not leave drips or puddles sit long, as in more than 5 seconds. I apply stain a row at a time, say 3 feet wide on hands and knees with a rag. Apply the entire length of the row and then go back and remove the excess with another cloth.
