Note to buyers: 1. The adhesive on the underside of the water barrier has not yet completely melted due to weather conditions. Heat the underside of the shower barrier with a hairdryer before use.1. The shower enclosure seal is only 12 mm high, so that the glue melts completely and adheres better. 2. The shower enclosure seal is only 12 mm high; it cannot block the water flow with a seal higher than 12 mm.Wide range of uses: Silicone shower barriers can be used on the edge of the worktop (kitchen sink, washbasin), floor, threshold (bedroom door, bathroom door), filling a gap of 0 to 20 mm (between the surfacework and the wall, between the bathtub and the wall) to help remove hard-to-clean debris stuck in crevices.Easy to install: First, clean and dry the floor surface, then measure and cut the shower threshold to the appropriate length. Next, remove the red adhesive backing and stick the threshold bar onto the smooth surface. Seal the edges with silicone after installation.Apply it so that it doesn't come loose later and lasts longer (Sealant not included in the packaging)High quality and easy to clean: The overflow threshold is made of food-grade organic silica gel, which is very effective at blocking water, separating wet and dry water, corrosion-resistant, and resistant to high pressure.It is resistant to temperature changes, wear, and has no particular odor. The material is flexible and can be cut as needed. The flood barrier surface is smooth and easy to clean; simply wipe it with a damp cloth.
