An installation method that can be used with a variety of materials, including laminates, engineered hardwood, luxury vinyl and rigid core flooring. In this method, individual planks (or in some cases tiles) interlock edge-to-edge to form a single mat-like surface that simply rests on the underlayment.

An installation method whereby the underlayment is first adhered to the subfloor with an adhesive, and the floor is then adhered to the underlayment.
