For a better seal, use a silicone sealant to fill the edges of the water barrier and allow it to dry for 24 hours until fully solidified (silicone sealant not included). The shower threshold strip has a height of only 0.47 inch (12 mm), which does not create movement obstacles. The bath splash guard can only be installed in a straight line and cannot be bent. At corners, it is recommended to cut the strip at a 45-degree angle and splice it into a 90-degree joint for stronger and more durable adhesion. Easy to Install: Clean and dry the surface of the counter or floor. Measure and cut the shower water stopper to the desired length. Peel off the red adhesive backing strip and apply it to a smooth, clean surface. In colder conditions, use a hair dryer to warm the strip slightly to enhance adhesive performance. Solves Water Leak Problems: The water dam barrier provides effective waterproofing. It can be used on shower floors, shower trays, kitchen sinks, under bathroom doors, bathtub edges, around washing machines, or toilets to create a reliable water barrier, preventing water from spreading and helping achieve wet and dry separation. Environmentally Friendly Silicone Material: The shower water barrier is made of high-quality solid silicone—waterproof, safe, odorless, resistant to high temperatures and wear, and built to last. The threshold strip is soft and flexible, allowing it to be cut to fit as needed. Its smooth surface is easy to clean, helping keep your bathroom and kitchen neat and tidy.
