I was polishing out a table top with Micro Mesh discs and the phone rang. The soapy water sat on the water-based poly finish for about 10 mins. I got back to find a serious blushing. I’ve never experianced this before, I’m normally very careful about not getting blush but the call was a lady that wants 8 pens. money in hand. My question is how deep does that blushing normally go? Am I better off stripping the finish and starting from scratch or is it sandable? I ask because instead of spending an hour or more sanding when I could remove the top and strip it in less then an hour.

Bill, not sure what poly you used but it should not have blushed , however .. it will usually dry out, warm it ( not hot) with a hair dryer .. it will help the moisture come out , also wiping it with a little denatured alcohol, will help, when you wipe it you want to just leave a gentle wispy tail, not soaking it, the alcohol will help draw the moisture as well as open the finish a bit to allow the moisture to escape easier … I have seen the same sort of thing also that looks like blush and in reality its the slurry from sanding which turns milky white sticking to the finish, in which case a little wetting and further sanding will remove it…

I’ve read that water based poly can take up to 30 days to fully cure, so it may have absorbed the water. Try warming it as was mentioned, or just wait a few days and see what happens. If it doesn’t clear up, then you’ll probably need to strip it.

Dontcha just love poly?
I have made it a life project to never use the stuff unless somebody just insists. Then I argue with ‘em.
I know….Other finishes will blush too. Used to spray NC lacquer on pianos on a rainy day in South Mississippi.
Talk about usin’ retarder….

Thank you folks. I’m gratuful for the advice. Charles, Ger21, ya both called it. I was gone all day, just looked at the top and the white cloud is gone. I sure didn’t want to strip that top. It has a walnut burl veneer as a center piece. that 1/42nd thick commercial stuff can be fragil even glued down. It had only cured 5 days. Its Hoods brand. Says cured in 72 hours and I normally give it 7 or 8 days. I think I’ll pass on rushing it next time. Thanks again.
