The Ella BathBud tile flange kit provides the perfect tile flange option for bathtubs and shower bases that lack a built-in tile flange. The BulkBox includes a 164-foot long, 4-inch wide Sealux patented waterproof membrane with an integrated 1 ¼-inch siliconized adhesive strip. The 164-foot roll of tile flange is sufficient for 16 shower base or tub alcove projects, each requiring a tile flange length of 124 inches (30x60 opening). This unique 0.5mm thick Sealux glue-up waterproof membrane (tile flange) serves as an innovative sealing system for the perimeter joint upstand of bathtub and shower trays. Designed to integrate seamlessly with your wall tiles or panels, the flange effectively prevents water from seeping between the bath and the tiles. This essential feature offers an extra layer of protection against long-term water damage to both the wall and the floor in the tub deck area, ensuring the longevity of your installation. To seal the gap between the shower base or bathtub and the wall-mounted glue-up Sealux flange, a neutral-curing, sanitary-grade, 100% silicone sealant must be used. When this silicone is applied into the gap with a caulking gun and contacts the Sealux siliconized adhesive strip, it forms an unparalleled bond with both the bathtub and shower base. This creates a flexible and waterproof seal that is maintained even during floor contractions, expansions, or any joint movements
