I poly'd my subfloor (anticipating having to set it on the rain before I was able to finish my build). Now that I have the walls/roof up I am wanting to put down either a hardwood/vinyl tile and I'm starting to think about adhesion. Ideally, I would use woodglue fastened on the studs for a hardwood floor. Knowing, glue first then poly...do I try and sand the poly finish off? I believe some of the new vinyl products use a sort of butyl/foam backer with adhesive.
Open to flooring suggesting and adhesives. I need to overcome some bolt heads as well that are not flush fit (had to leave them proud bcuz of ply/foam/ply sandwich)
