how long to dry? it's taking foreverrrrrr!!
Hi, I have 3 - 20" squares of 1/4" plywood that I'm going to place under a mattress to make uber firm support. (long story) but the question is-- I used Thompsons water sealer, 2 coats, and it's been like maybe 5 days or longer and it is still a bit damp in some areas i see the shine, and rub my fingers on the areas and get oil on them. I don't get it, they were dry between coats. How long does it take?? I even have them sitting against the garage in the sun (luckily we are having a warm spell here in SF bay area. but jeeeez, I have delayed having the mattress delivered. (God forbid when I do a deck this spring!!) I was told to put a spray of polyurethane (interior use kind) on top when this dries --I have to be 100% not allowing moisture to penetrate the wood. HELP !!!!!!!!!
