1. Waterproof floor transition strips, floor joint strips, and threshold strips are made of quality PVC material. The surface is scratchresistant, wearresistant, dirtrepellent, easy to clean, and stainresistant. Unlike other similar products made of aluminum alloy, PVC material is softer. 2. The waterproof, selfadhesive floor transition strips make it easy to cover cracks and gaps. Simply measure and cut the desired length, peel off the adhesive backing, and stick it onto a smooth surface. They have viscosity and are durable. 3. The joint cover strips are suitable for floor gaps (wood to tile/wood to wood/tile to tile). Additionally, the floor edge strips can adhere to almost any smooth surface (tiles, plastic, marble, metal, glass, hardwood, smooth walls, etc.). 4. The flexible molding strip is for covering gaps where two floor surfaces meet in the bedroom, living room, kitchen, or shower area. The transition strip can also be used as decoration for accent walls, moldings, edges, cabinets, mirrors, and more.
