- Foldable and waterproof self-adhesive dam for shower edges: grips firmly to prevent water flow, folds to fit curved or irregular shapes, forming a small waterproof barrier. The white color blends with most bathroom decors. - Advanced materials: made of high-quality TPE, environmentally friendly, waterproof, mildew resistant, and non-deformable. Separates dry and wet areas. Can be easily cut to the desired length; the water retention strip is flexible for creating different shapes. - Soft and harmless: soft on feet and safe for the family. Easy to clean—wipe the surface with a damp cloth. - Easy installation: 1. Wipe the floor dry with a cloth. 2. Mark the location. 3. Remove the primer and stick the water retention strip at the marked position. 4. Press the water lock lever into position. 5. Stretch the water holding strips at both ends and stick them on both sides. 6. Leave it for 24 hours. - Use scenarios: 1) Seal gaps between a shower enclosure and bathroom floor to prevent water overflow. 2) Fit irregular edges around tubs, shower doors, or thresholds to contain moisture. 3) Use in laundry rooms or other wet areas to create a dry-wet separation quickly and reliably.
