Easy installation: the first step is to dry clean the surface of the installation and then stick the water blocking strip to the floor. The second step is to glue where the water retention strip touches the floor (warm tips: our item does not contain waterproof glue). Water stopper material with shower threshold: Soft silicone rubber, corrosion-resistant, high-temperature-resistant and wear-resistant. Bendable when stepped on, it immediately springs back into its original shape. Bendable Water Flow Blocking Strip: You can bend it according to the environment for a water blocking effect. The length can be cut with a cutter to more closely match the scene. Soft and Harmless: The weatherstrip is soft and won't hurt your feet, so it doesn't matter if you kick it to keep you and your family safe. The surface is easy to clean, all you need is a wet towel to wipe it like new. Can be cut to size: If the surge protection strip is too long, it can simply be shortened with a cutter knife or scissors and cut to size for your shower. Note: the molding is glued to the floor, not the door. How to use: 1. Wipe off the water and dust on the floor. 2. Determine the position of the threshold and mark it on the floor with a pen. 3. Remove the adhesive and attach the threshold to the marked location. 4. Seal the rubber strip where the ends of the water stop touch the wall. 5. Apply adhesive evenly to both sides of the threshold.
