The BOSTIK FLEXIBLE TANKING SYSTEM is a complete, multi-component waterproof membrane designed to protect tiled areas in wet-rooms, showers, bathrooms, and utility spaces.
This system effectively prevents moisture from passing through the tiled surface and into water-sensitive substrates like plasterboard, timber, and concrete floors. It creates a seamless, durable protective layer that bridges fine cracks and joints, accommodating slight structural movement and vibration. The system consists of a primer for optimal adhesion, a flexible grey waterproof coating, and super-strong polyester matting to reinforce seams and joints (like wall/floor junctions and pipe entries).
