For a better seal, use silicone sealant to fill the edges of the water barrier and allow 24 hours to dry until fully solidified (silicone sealant not included). The shower threshold strip has a height of 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, cut at a 45-degree angle and splice at 90 degrees for stronger, more durable adhesion. Easy to Install: Clean and dry the surface before installation. Measure and cut the shower water stopper to the desired length. Peel off the red adhesive backing and apply to a smooth, dry surface. In colder conditions, use a hair dryer to warm the adhesive for improved stickiness. Solve 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 spread and enabling wet and dry separation. Environmentally Friendly Silicone Material: Made of high-quality solid silicone, the shower water barrier is waterproof, safe, odorless, heat-resistant, wear-resistant, and durable. The threshold strip is soft and flexible, allowing for custom cuts as needed. Its smooth surface is easy to clean, helping maintain a neat and tidy kitchen or bathroom.
