glues used in interior water dammage repairs
Two yrs. ago we did extensive wall tearout due to water damage. On the bare fiberglass we used 3M bondo as this sealed up to a hard shinny finish and sealed any pinpoint leake we couldn't see. Then we used heavy duty liquid nails to do any gluing of Styrofoam insulation,1/8th underlay and 1/8th paneling. Cheapest at Walmart. Others have used contact cement or two part epoxy (gorilla Glue.) We recently we in a huge rainstorm while camping and were high and dry. Use a floor roller to press the layers of your wall together. We also used spray foam caulk as needed on the interior walls. A very good caulk to use is Lexell caulk. We used this both interior and exterior. It sells for about 8$ at ACE hardwear or on line. Worth every penny. Best of luck with your repairs.
