Hi, We are second owners of a 11yr old house built over a crawl space. There has never been any moisture issues in the crawl space and we use it for storage. We are pulling up the old glued down commercial carpet and will put down Golden Select ash laminate with a foam backing. We are doing the work in sections. The carpet has pulled up very easy leavening all the glue on the plywood subfloor. The glue is slightly Tacky but even. I was considering putting a underlay that has a moisture barrier since I am unsure if one was installed under the gravel floor in the crawl space when the house was built. Good idea or not? Also if I use the underlay does the old glue need to be scrapped off? Lastly will there be a friction problem between the underlay and the flooring?
