The ultimate tanking solution for bathrooms, showers and wet rooms. BW1 is a no-fuss option that’s so easy to use – it’s a fast-curing indoor waterproofing membrane that requires no priming, dramatically reducing both the time and cost of installation.
Based on C-TEC’s unique TRIBRID® Technology with an advanced polymer formulation, BW1 delivers enhanced bonding strength and incredible flexibility. It’s compatible with most substrates commonly used in bathroom construction such as concrete, brick, wood, plasterboard, fibre cement board and foam backer board.
