Note: Clean the surface thoroughly and let it dry. This step is very important. Let it dry for at least 24 hours without contact with water. The long, flexible design allows you to create all kinds of shapes. The shower barrier and retention system keep water inside the threshold. Ideal for curbless showers and other areas where water needs to be contained. Barrier dimensions: 100cm (L) x 3cm (W) x 5cm (H). Can be easily cut to the length you need.
