Easy to install: First clean and dry the countertop (or floor), measure and cut the shower water stopper to your desired length, peel off the red self-adhesive backing, and stick it onto a smooth surface (in winter, you can use a hair dryer to heat it for better viscosity). For a better seal, use silicone sealant to fill the edges of the water stopper barrier and let it dry for 24 hours until the sealant has cured (the package does not include silicone sealant). High-quality silicone material: The water dam is made of food-grade organic silicone, which is corrosion-resistant, high-temperature resistant, and wear-resistant. The bathtub edge strip is soft and will not hurt your feet. Wide application: It can be used on shower floors, shower trays, sinks, under bathroom doors, bathtub edges, around washing machines or toilets to form a water barrier, effectively stopping water flow and achieving wet-dry separation, keeping your home away from moisture! Dimensions: The size of the silicone water barrier is 20 mm width x 12 mm height, there are two installation methods, you can choose to install it horizontally or vertically depending on the size of the opening (as shown in the picture); 2 meters long, you can easily cut it to the length you need! Note: The bath splash guard can only be attached in a straight line, not curved. At the corners, we recommend cutting at 45 degrees and splicing at 90 degrees to stick; the adhesion will be more durable and strong.
