Staircases present unique structural requirements for flooring. Because floating floors are designed to move, they are inherently unsafe on stairs without full-trowel adhesive bonding. Installers must use stair-specific nosing profiles that bridge the gap between the riser and the tread. All planks must be firmly glued to the substrate to prevent separation, slippage, or tripping hazards, and the surface must be level to provide a consistent base for the adhesive application.
