Hey I am about to begin my IPE deck and I need to get some glue. I will be using 1x6 IPA and be screwing it down with #8 x 21/2 Trim Head Screws. I have read a few posts on this forum about gluing the boards to help act as a vapor barrier, as well as hold. I have also read on other forums that the glues do not rally hold.

So, is it worthwhile to glue? If so, what glue? Do I use gorilla, some form of liquid nails?? Any others?

Also, how far in from the edge should I place my screws? I was thinking 3/4".

TIA...Mike
