Installation Notes:1. Around the Italian shower barrier must be sealed with additional glue putty (package does not include). 2. For better adhesion, you can heat the back glue with a hair dryer. 3. In the corner, we recommend cutting it at 45 degrees, then connecting two parts to ensure its firmness. Height 12mm/0.47inch:The height of the bathroom shower barrier is only 12mm. Compared to the foldable shower tray seal, it cannot block the water flow with a height > 12mm, but the low height will not cause movement obstacles and can block the spread of water in a large area. Please clarify your needs before purchasing. Wide use: 1. The kitchen worktop seal can be used on the edge of the worktop (kitchen sink, washbasin, window sill, bathtub edge). 2. Can be used on the floor (bathroom floor, shower tray, around the toilet or washing machine, balcony floor).3. Can be used as a threshold (bedroom door, bathroom door). 4. Can be used to block gaps of 0-20mm (between the countertop (bathtub, floor) and wall.
