Removable Glue. Armstrong’s S-289 Releasable Sheet Floor Adhesive is a water-based low-VOC formulation designed to make residential vinyl-backed flooring easier to install and repair. According to the maker, it prevents newly installed flooring from shifting without interfering with adjustments; if the flooring ever needs to be patched or removed, the adhesive won’t pull off the backing or mar the substrate. It comes in 1- and 4-gallon pails and costs about $60 per gallon. Armstrong World Industries, 877/276-7876, armstrong.com
