pirozzi Posted January 20, 2014 Share #1 Posted January 20, 2014 Does anybody know how to undo good PVA glue? I glued something made of plywood that needs to be undone. The glue has set for about 3 days. Vince P. Quote Link to comment Share on other sites More sharing options...
augie Posted January 20, 2014 Share #2 Posted January 20, 2014 Isopropyl alcohol usually does the trick on PVA. The normal version is 70% but WalMart usually sells a 91% which I find best.

moflea Posted January 21, 2014 Share #4 Posted January 21, 2014 Hello, PVA (if not water resistant) can be soaked in water and it will break, but can also damage the plywood. I had some very good results just keeping it under my wife's hair dryer. After all, PVA is just plastic, it will melt in the heat. (that worked for my wrong glued bulkheads). Augie's advice might work even better, as a "last solution" Quote Alex. Current build: Constructo's Union, 1:100 Brigantine Link to comment Share on other sites More sharing options...
pirozzi Posted January 21, 2014 Author Share #5 Posted January 21, 2014 Hi Moflea, Thanks for the tip. It worked using the hair dryer. My wife also suggested that. Vince Quote Link to comment Share on other sites More sharing options...
