I hope I'm in the correct forum, new here so it seemed like the most likely place. 2 projects I've done in the past week and 1/2 have had this same issue. I have used 20mil paper backed maple veneer over ply to finish a profect, one in a pyramid table base and a table top. The day after the veneer was applied I have found long bubbles under the veneer. After doing the table base it rained the fallowing day and was very humid i fugued that was the problem to day I went in the shop and the table top has bubbles under the venner also. On both of these projects I did not use a vacuum system just the old fasion way, pressure with a 3" wide piece of wood. I live in Georgia so humity is usually high. Any ideas on how to cure or prevent?
Thanks
