I have 2 exterior porches that were built a few years ago (before I owned the house) On the underside of the ceiling there is bead board that never had a finish applied. I want to apply a clear finish, but there are some dark moisture stains that would show through. Can anyone tell me a way to remove those moisture stains? If I need to stain the wood to cover them before I apply the clear, that would be fine, but I think they would show right through the stain. Any suggestions? Thanks

if brown water stain ( tanic acid ) try bleach. As strong as you can stand...it may take a couple of attempts.

This trick will work on stains on drywall also.

If you stain do a pop grain and play with the water damage areas with care to try to blend. ( damaged area will take stain to a very dark tone).

good luck

Thanks Bob,
It is a brown stain, I will try the bleach. I just don't want to create a real light area that will show. What do you mean by "pop grain", I'm not familiar with the term?

[Big Bob]

pop grain, wood flooring technique, wet wood with water, grain swells and takes stain deeper. Test some areas see what you like or that will work well for you.


wipe on wipe off.less is more (Better)

Thanks again for the advice, tried the bleach today, and it worked like a charm. I won't even need to stain, just coat it with some spar varnish.
