Hi,
I live in Victoria and are wondering if I must waterproof my laundry? If so, what products do I need and what steps must I follow to do this? Any advice would be greatly appreciated.
Hello @Jojo17
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your laundry.
If you're building or renovating a laundry in Victoria, waterproofing is generally considered an important part of creating a durable and compliant wet area. While the exact requirements can vary depending on factors such as whether the room has a floor waste, the type of flooring, and the overall design, protecting the floor and critical junctions from water ingress is a wise investment that can help prevent costly damage in the future. Victoria follows the National Construction Code and Australian Standard AS 3740 for wet area waterproofing, so it's always worth checking your specific situation if you're undertaking major works. I also recommend checking your local council's rules and regulations in regard to waterproofing your laundry.
In regard to what product to use for a waterproofing project, I suggest looking at a high-quality liquid-applied membrane such as the https://www.bunnings.com.au/davco-20l-green-k10-plus-waterproofing-agent_p0960052 , a flexible Class III waterproofing membrane designed for use under tiles in wet areas. It is water-based, ready to use and suitable for residential laundry floors and walls where waterproofing is required. Another option is the https://www.bunnings.com.au/crommelin-15l-shower-waterproofing-membrane_p0960103 , which complies with AS 3740 and is specifically designed for wet areas including laundries, bathrooms and showers before tiling.
The process itself begins with ensuring the substrate is clean, sound and dry. A suitable primer is typically applied first, followed by the installation of bond breakers or reinforcing tape at all wall-to-floor junctions, corners and around any pipe penetrations. Once these details are completed, the waterproofing membrane is applied in at least two coats, with the second coat applied after the first has dried sufficiently. Care should be taken to achieve the manufacturer's recommended coverage and membrane thickness. After the membrane has fully cured, the area can then be tiled using a compatible tile adhesive and grout system.
Just a quick reminder that any waterproofing work will need to be carried out by a certified waterproofing professional to ensure everything is done safely and meets compliance requirements.
