The collapsible dam erects a barrier to prevent water from spilling out of the curbless shower, keeping the bathroom floor dry and safe. It can be easily cut to the length you need. Flexible design allows for a variety of uses and applications. Before installation, clean and dry the surface, use a hair dryer to heat the installation surface and adhesive for better adhesion, peel and stick to the surface within minutes. For extra support and waterproofing, it is recommended to seal the bottom edge with clear silicone caulk (not included) after joining. Easy to clean, just wipe with a damp towel. Ideal for use in kitchens, bathrooms and other places where water flow needs to be controlled, such as angled shower trays, toilets, sinks, etc.
