Waterproof Before Tiling

Under-tile waterproofing protects bathrooms, showers, laundries, balconies and other tiled wet areas before the tile adhesive and finish are installed. This range brings together liquid, sheet and cementitious membranes with the tapes, bands and shower detailing needed to complete the wet-area system.

Choose the membrane first

For bathrooms and showers, select a membrane approved for the substrate and intended wet-area use, then match it with the correct primer, bond breaker, reinforcement and tile adhesive. External tiled balconies and decks add further requirements such as movement, weather exposure and minimum dry film thickness.

Detail corners, joints and penetrations

Waterproofing performance depends on more than the field membrane. Compatible tapes, bands, sealants, hobs and waterstop details help manage movement at corners, joints, penetrations and floor transitions. Installation must follow the current product data and applicable NCC and Australian wet-area waterproofing requirements.
