Edge curling in glue-down luxury vinyl typically occurs due to the intersection of environmental stressors and installation oversights. Luxury vinyl is a thermoplastic material, meaning it is susceptible to dimensional instability when exposed to significant heat or moisture. When a room experiences sharp temperature fluctuations—such as intense solar gain through large windows—the individual planks may attempt to expand at a rate faster than the adhesive can manage. If the adhesive bond at the perimeter of the plank is weak or incomplete, the internal stresses of the material will cause the edges to lift or curl rather than remaining flush with the floor. Furthermore, the quality and application of the adhesive are paramount. If an installer uses an incorrect trowel size, fails to achieve full adhesive transfer to the back of the plank, or attempts to lay the flooring while the adhesive is still too wet or past its open time, the bond will be compromised. In such scenarios, the edges are the first to lose their grip, allowing moisture ingress from cleaning or spills to further deteriorate the bond, leading to permanent curling. To prevent this, one must ensure a perfectly clean substrate, use the exact adhesive specified by the manufacturer, and strictly follow the recommended flash times for the adhesive to ensure a robust, uniform bond across the entire surface area of the plank.
