Gripset Betta Exterior Corner Joint Band is a flexible reinforcement tape for waterproofing critical junctions. Designed to embed into liquid membranes, it bridges corners, wall-to-floor transitions and movement-prone areas to improve crack resistance and system integrity. Easy to cut and conform, it enhances durability in external applications such as balconies, terraces and façades. Use over clean, primed surfaces and fully wet-out with the compatible membrane for a seamless, long-lasting seal.
