Easy to Install: Clean and dry the surface before installation. Measure and cut the shower water stopper to the desired length. Peel off the adhesive backing and press firmly onto a smooth, clean surface. For better adhesion in cold conditions, use a hair dryer to warm the strip prior to application. For improved sealing, apply a silicone sealant along the edges of the water barrier and allow 24 hours for full curing. (Silicone sealant not included.) Effective Water Barrier: This shower threshold strip helps prevent water leakage and provides an effective waterproof seal. It can be used on shower floors, shower trays, kitchen sinks, under bathroom doors, around bathtubs, washing machines, or toilets to contain water flow and support wet and dry area separation. Durable Silicone Construction: Made from high-quality, flexible silicone, this water stop barrier is waterproof, odorless, heat-resistant, and durable. The material is smooth, easy to clean, and resistant to wear. The strip can be cut to fit straight installations but is not designed to be bent. For corner installations, cut each piece at a 45-degree angle and join to form a 90-degree corner for stronger adhesion. Low Profile Design: With a height of only 0.47 inch (12 mm), the threshold strip is low enough to avoid tripping hazards while still providing effective splash protection.
