I've got a back gate made from plywood. I'm guessing its waterproof as its been there for about 12 years (we've been here 1) and its all fine except for the bottom corner which has peeled away. The bottom edge has a number of screws across the bottom but a small corner has still peeled away even though its about 3-5mm clear of the ground. Rest of the gate is fine (including top edge which would get wet in rain). Is there anything I can do to stick this edge back on? I'm guessing some glue and re-screwing the problem bit (and clamping whilst it sets) but I'm unsure what glue to use.
Thanks
