How can I waterproof my bathroom?

Waterproofing a bathroom is easy to do using a waterproof membrane such as one from our Tile Adhesives & Grout range.

Cover the entire floor, up the walls about one foot, and the entire shower area (walls to ceiling) and floor with the membrane, ensure every inch is covered well. Apply a second coat as per the manufacturer’s instructions to ensure a water-tight seal.

Learn more in our article, ‘How to install bathroom tiles’, where you’ll find a section on making a bathroom water-tight.

It’s important to note that you will need a compliance certificate for your waterproofing if you are putting your bathroom renovation through the council. In such a case, water waterproofing must comply with Australian Standard AS 3740. Thus, you will need to hire a qualified waterproofer who has completed a Certificate III in waterproofing to waterproof your bathroom.
