Elastilon Self-Adhesive Underlay Membrane promises to make installing a solid hardwood floor as easy as a laminate job. This 1/8-inch-thick resilient membrane features a peel-and-stick top layer that unites the disparate pieces — without nails or glue — to create a floating floor. It’s compatible with all hardwood species and can be applied directly over a concrete floor. Compared with conventional fastening schemes, this process cuts install time by as much as 70 percent, says the manufacturer. The membrane costs $1.85 per square foot.
