Bathroom Waterproofing Brisbane

Bathroom Waterproofing

The bathroom is one of the wettest areas of the home. Thus, it’s important to make sure that no moisture escapes from it to other parts of the home. This is done through waterproofing, which involves the application of a suitable barrier to make sure that water doesn’t escape the wet areas of a building.

Homeowners typically waterproof their bathrooms during construction or renovations. The waterproofing should be done correctly, otherwise, moisture penetration may cause serious structural damages to your structures and home. As such, you need to hire a qualified and experienced waterproofing contractor to take care of your Sunshine Coast bathroom; like Queensland Interior Linings.

Australian standards for bathroom waterproofing

In Australia, regulations vary from state to state. But as a general rule, the Building Code of Australia (BCA) and the Australian Standards (AS 3740-1994) lay out the following minimum standards;

The entire shower floor must be waterproofed. On the other hand, shower walls must be waterproofed to a minimum height of 1800mm.
Bathroom walls must be waterproofed to a height of at least 150 mm.
If the bathroom floor is made of/contains wood, the entire floor must be waterproofed. The same applies if the bathroom is on the second story or higher.
The step-down or hob from the shower to the floor must be waterproofed up to a height of 100 mm.

All residential homes in the country must comply with the above regulations.

How do you waterproof a bathroom?

Bathroom waterproofing is usually done in stages. There are different ways to go about it, and your contractor will pick the most appropriate method depending on your situation.

Generally though, the wall and floor surfaces of your bathroom must first be cleaned and primed for waterproofing. This is done using a broom and dustpan to remove dust and other particles. The contractor will also smoothen any uneven sections of the floor and wall and dry out any water in the bathroom space.

The primer is then applied on the entire floor and 150 mm up the walls and allowed to dry. Silicon may also be applied to close any gaps and cracks and allowed to dry over 24 hours. The waterproofing agent and membrane will later be applied up to the required height and also left to dry for 24 hours.

Finally, a second coat of waterproofing membrane is applied to the entire area. Once it drys up, your bathroom is waterproofed.
