Exterior Basement Door - best way to glue
I have an entrance into my basement from my back patio — we use it fairly regularly, but not daily. In order to keep snow/rain out (and to maximize the sq footage of a very small backyard), I've built a new door to cover the entrance.
I used 3/4" plywood as underlayment...with 1" cedar shiplapped on top. Once it is finished and protected, I'll add gas shocks below to help with easy opening/closing.
My question: what's the best way to attach the cedar to the plywood? I was planning on using construction adhesive + screws from below every 6" or so.
My only concern is how will the weather affect this? We see a lot of freeze / thaw cycles (I live in Colorado) ...we get a lot of sun....and it will have moisture on top.
My thought was that the shiplap might help keep things tighter...and then the adhesive + screws will lock it in.
Any thoughts? Thanks everyone!
