Waterproofing a bathroom is essential, and is a regulatory requirement under national standards. Councils also require certification of waterproofing for all new builds. Waterproofing is one area which one should not skimp on in terms of cost, as a shoddy job will be expensive to remedy. If your bathroom is not waterproofed properly, or there is a leak the most obvious signs to look for are stains on the walls, flooring or tiles. Grout may also start to flake and fall out. It is crucial to waterproof areas where there will be constant exposure to moisture. This includes the floors, shower base and walls, as well as the bath area. A waterproofer will use a range of products to ensure that your bathroom is compliant, including: sealants, sheet membranes, epoxy, and polyurethane membranes.

Waterproofing a bathroom typically comprises four essential steps:

• cleaning the surface of old material
• priming the clean surface
• sealing the surface
• applying the waterproofing material or substance

Waterproofing is a specialised task. Consult the Building Code of Australia and a professional in the trade, before you undertake any waterproofing of your bathroom.
