I took the deck off my trailer frame and removed the plywood from the framing so that I could properly biscuit join the 2 pieces of 3/4" ply floor as well as glue it all to the frame. (In the rush I was in when I moved to TX, I just dry fit everything and put the deck on the trailer so I could pull a load of stuff.) I read that PL Premium is most builders' adhesive of choice. When I used it I used a 4 inch screw to break the seal and moved it around to make sure the seal was as opened up as I could get it before I started trying to pump it from the caulk gun. It was so thick it was almost impossible to squeeze the trigger on the caulk gun and eventually the caulk gun started to bend. When it came out it I worked the 3/8" bead that I laid down into the intended area of adhesion with a small paint scraper.
Because of the thickness I used a lot of clamps. I'm wondering if this is normal. Is PL Premium really that hard to work with? It's my first time working with it. I was using the 8x version. Based on my experience with PL Premium I glued in the second piece of plywood (to the 2" x 2" frame) with Titebond III. I have never had a problem with Titebond and it's super easy to use. Just wanted to double-check with you guys to see if maybe I got a bad batch. I ended up just tossing the second tube. Might try returning it. The gluing of floor to frame isn't that big a deal because it's all bolted to the frame with carriage bolts. When I get the deck done I will be gluing the sides on and hoping to get all this sorted out before that day.
Thanks,
