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, flat surface. In colder temperatures, use a hair dryer to warm the adhesive for improved bonding. For best results, apply silicone sealant along the edges of the water barrier and allow 24 hours for full curing (silicone sealant not included). Effective Water Protection: This shower threshold strip helps prevent water leakage and is ideal for use on shower floors, shower trays, kitchen sinks, under bathroom doors, bathtub edges, around washing machines, or toilets. It creates a reliable water barrier to contain splashes and support wet and dry area separation. Durable and Flexible Design: Made from high-quality silicone, the water stop barrier is waterproof, odorless, heat-resistant, and wear-resistant. The material is soft and flexible, allowing for straight installations and 45-degree corner cuts for seamless 90-degree joins. The smooth surface is easy to clean and maintain. Low Profile: The shower threshold strip has a height of only 0.47 inch (12 mm), providing an effective water barrier without creating a tripping hazard. Note: This product is designed for straight installations only and cannot be bent. For corner installations, cut and join pieces at 45-degree angles for a secure fit.
