1. Food grade silicone: The wet room floor seal is made of organic food grade silicone, which is corrosionresistant, temperature resistant, wearresistant, and odor. It is flexible and can be cut to size. It is very easy to clean thanks to its smooth surface. 2. Suitable size: The silicone water barrier measures 12 mm in height and 20 mm in width. It offers two installation methods—horizontal or vertical—depending on the gap size (as shown in the image). The 1meter length can be trimmed to the needed size. 3. Installation instructions: The shower water barrier must be sealed with additional sealant (not included in the package). For better adhesion, heat the back adhesive with a hair dryer. For corners, cut the barrier at a 45degree angle and join two pieces to ensure strength. 4. Wide application: The shower floor barrier effectively contains water within the threshold, preventing water flow. It can be used on shower floors, shower trays, kitchen sinks, bathtub edges, and more as a water barrier. (Note: Due to packaging variations, slight color deviations (gray) and size differences of 1–2 mm may occur.)
