I borrowed a truck today to pick up some plywood for my redecking project and the selection at Home Depot in Alvin was horrible. I left empty handed. Even for Home Depot it was bad. The 1/2" pressure treated was moldy and mostly voids and knots. The 3/4" was better but I didn't want to add the extra weight unnecessarily. Does anyone know of a good lumber yard I can get some good 1/2" pressure treated plywood from? Also just because I don't know any better why can't I just use some cheap OSB? Since it'll be coated in resin does it matter? I don't mind spending the extra bucks to do it right but honestly my primitive caveman brain can't see the difference once it's glassed in.
