Three frequent causes of joint seal failure around shower bases and bathtubs are a combination of:

Problem 1: The sealant bridge between the wall tile and receptor splits under the effects of joint expansion and the joint leaks. Joint sealant between the tile and receptor cannot be relied upon to remain waterproof without periodic inspection, maintenance and replacement to prevent consequential damage. For this reason the joint itself is often referred to as a ‘maintenance joint’. Unfortunately, in many cases it is the notice of a leak that instigates joint inspection at which time it is already too late because the damage is done!

Solution: Don’t rely on joint sealant between the tile and receptor as the exclusive means of waterproofing the joint. Install FlangeBand as a permanent secondary movement joint seal behind the exposed tile/receptor joint sealant.

Problem 2: Joint sealant between the tile and receptor naturally deteriorates under frequent exposure to the chemicals and physical weathering in modern shower environments. Sealant deterioration is another cause leaks.

Solution: FlangeBand is designed to conceal and protect the silicone from direct exposure to the deteriorating effects shower environments. Once installed, FlangeBand delivers a permanent watertight maintenance-free joint seal.

Problem 3: Under the effects of joint expansion, sealant between the tile and receptor can suffer a loss of adhesion with the receptor or tile resulting in water leaks and wicking.

Solution: The Sealux strip has a red tinged surface specially primed for tenacious adhesion with Sealux-N silicone. When FlangeBand is installed to seal a tub or shower base with or without a tile flange, tenacious adhesion between strip and silicone, flexibility in the Sealux-N silicone and elasticity in the Sealux strip collectively accommodate the joint expansion and maintain seal integrity.

Conclusion: Installing FlangeBand as a permanent secondary concealed movement joint seal behind the exposed tile/receptor joint sealant ensures that when the sealant joint between the tile and receptor fails, the resulting leak is contained inside the shower area.
