we recently purchased old farm. The barn doesn't have a floor, which is fine, however the ground is very fine sand. A few years ago Bob had a show in Arizona and the landscapers sprayed a chemical on the sand to harden it for pathways. I was wondering if this chemical would work to firm up our barn floor and what it is called and where we might purchase it. Also, is it very expensive? Does anyone have any other suggestions for solving this problem?
