Texan6923 Posted December 22, 2016 Report Share Posted December 22, 2016 Im new to this cite and working with wood. I will appreciate any and all answers to my question. But i had poured epoxy on 2 pieces of mesquite wood and let them dry. In certain places there was a white haze like this. Any idea what it is and how to prevent it in the future. Ive been told its just air but i want to be sure. Quote Link to comment Share on other sites More sharing options...
xxdabroxx Posted December 22, 2016 Report Share Posted December 22, 2016 Could it be moisture? I know a heat gun is sometimes used to pop bubbles in epoxy and resins. Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted December 23, 2016 Report Share Posted December 23, 2016 How wet was the wood you poured the epoxy on, that looks like moisture underneath. Quote Link to comment Share on other sites More sharing options...
Texan6923 Posted December 23, 2016 Author Report Share Posted December 23, 2016 I had sanded and cleaned it off with an air gun not long before i poured the epoxy. And it felt dry to the touch. But i guess the moisture seeped out after i poured it. Quote Link to comment Share on other sites More sharing options...
Coop Posted December 23, 2016 Report Share Posted December 23, 2016 I think he meant what is the moisture content of the wood. How long had it been drying. Nothing to do with your problem, but where did you get the mesquite and where in TEXAS are you? Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted December 23, 2016 Report Share Posted December 23, 2016 Is that purchased lumber or wood from a log of already built furniture? Quote Link to comment Share on other sites More sharing options...

Brendon_t Posted December 23, 2016 Report Share Posted December 23, 2016 Then call this lessons 1 in wood. It needs to be dried to use. Usually about a year per inch of thickness. Quote Link to comment Share on other sites More sharing options...
drzaius Posted December 24, 2016 Report Share Posted December 24, 2016 The haze will be the least of your problems. Soon it will begin to crack & warp as well. Bummer. Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted December 24, 2016 Report Share Posted December 24, 2016 If it is all epoxied, I wouldn't expect too much crazy cracking and checking. The epoxy is clearly holding in the moisture on the top there. If it does that all around, it'll likely never dry. Just be soggy Quote Link to comment Share on other sites More sharing options...
drzaius Posted December 24, 2016 Report Share Posted December 24, 2016 But the epoxy will only slow the process. It will eventually happen, though maybe not as severely. Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted December 24, 2016 Report Share Posted December 24, 2016 Maybe I don't understand Epoxy but it is used to waterproof boat hulls. I didn't think it would permeate at all. Quote Link to comment Share on other sites More sharing options...

After you strip all the epoxy down, use a thick coating of latex paint on the end grain. The goal is to slow down the drying process through the end grain that is susceptible to fracturing due to rapid moisture loss 1 Quote Link to comment Share on other sites More sharing options...

I didn't think it would permeate at all. With wooden boats, the real waterproofing is a result of the wood in the hull absorbing a little bit of water, to the point where it swells up to form a perfect seal between the planks. (Check out the Tips From a Shipwright, Q&A episode from yesterday for a good explanation of that) I don't think there is any coating that will completely seal wood well enough to prevent moisture transfer. There are always microscopic cracks that will develop that'll let moisture pass. Quote Link to comment Share on other sites More sharing options...
