For a better seal, it is necessary to 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 is not included with this product). The shower threshold strip has a height of only 0.47 inch (12 mm), which ensures it does not create a tripping hazard. The bath splash guard can only be installed in a straight line and should not be bent. At corners, we recommend cutting the ends at 45 degrees and joining them at a 90-degree angle for a stronger, more durable bond. Easy to Install: Clean and dry the surface of the countertop or floor before installation. Measure and cut the shower water stopper to the desired length. Peel off the red adhesive backing strip and apply to a smooth, clean surface. In colder conditions, use a hair dryer to warm the adhesive for improved stickiness. For optimal performance, apply silicone sealant along the edges of the water stopper and let it cure for 24 hours. Solve Water Leak Problems: This water dam barrier provides effective waterproofing. It can be used on shower floors, shower trays, kitchen sinks, beneath bathroom doors, bathtub edges, around washing machines, or toilets to create a reliable water barrier that prevents water from spreading and helps achieve wet and dry separation. Environmentally Friendly Silicone Material: Made from 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 it to be cut to fit as needed. Its smooth surface is easy to clean, helping maintain a neat and hygienic environment in your bathroom or kitchen.
