For a better seal, use silicone sealant to fill the edges of the water barrier and allow 24 hours drying time for full solidification (silicone sealant not included). The shower threshold strip has a height of 0.47 inch (12 mm), which does not create a tripping hazard. The bath splash guard is designed for straight installations only and cannot be bent. For 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 thoroughly, measure and cut the shower water stopper to the desired length, peel off the red adhesive backing, and apply to a smooth, flat surface. In colder temperatures, use a hair dryer to warm the adhesive for improved stickiness. The water dam barrier provides effective waterproofing and can be used on shower floors, shower trays, kitchen sinks, under bathroom doors, bathtub edges, around washing machines, or toilets to prevent water leakage and support wet and dry separation. Made from high-quality, environmentally friendly silicone, the shower water barrier is waterproof, safe, odorless, heat-resistant, wear-resistant, and durable. The threshold strip is soft and flexible, can be cut to fit as needed, and features a smooth surface that is easy to clean, helping maintain a neat and tidy kitchen or bathroom.
