AUSTRALIA-WIDE SHIPPING
Bunnings waterproofing refers to the range of waterproofing products and solutions available at Bunnings Warehouse stores and online across Australia — including waterproof membranes, sealants, primers, bitumen coatings, and specialised paints. In simple terms, waterproofing is the process of applying products to surfaces (like bathrooms, balconies, concrete slabs, walls and ponds) to prevent water from penetrating where it shouldn’t, protecting structures from moisture damage, mould and costly repairs. The main reason Australians turn to Bunnings waterproofing products is that they offer a wide range of DIY‑friendly solutions with expert advice, making essential water‑protection jobs more achievable at home.
Here’s why waterproofing matters: moisture penetration can lead to blistered paint, structural decay, mould growth and expensive restoration, so applying the right waterproofing system early adds longevity and value to your home.
Types and Styles of Bunnings Waterproofing Products
Waterproofing products at Bunnings come in different forms to suit varied tasks — from wet areas inside the home to outdoor surfaces.
1. Brush‑On Waterproofing Membranes
Liquid membranes that form a waterproof layer when dry:
-
Acrylic or rubber‑based membranes
-
Applied with brush or roller before tiling or painting
-
Suitable for balconies, bathrooms, decks and planter boxes
2. Undershower / Undertile Waterproofing Membranes
Designed to create a watertight seal beneath tiles:
-
Wet‑area membranes used before tiling
-
Often paired with joint sealers and reinforcing tape
-
Ideal for showers and laundry areas
3. Bitumen & Asphalt Coatings
Heavy‑duty liquid coatings for tougher surfaces:
-
Bitumen paint and sealants for driveways, basements or slabs
-
Provides strong water resistance against rain and ground moisture
4. Primers & Preparatory Sealers
Surface preparation before applying membranes:
-
Improve adhesion and durability
-
Essential for porous substrates like concrete and render
5. Pond & Concrete Sealers
Clear or coloured coatings that waterproof outdoor concrete structures:
-
Suitable for ponds, water features or exposed paved areas
-
Often can be over‑coated with paint or tiles
6. Joint Sealants & Bond Breakers
Products that seal gaps and prevent water ingress:
-
Silicone or SMP sealants designed to be flexible
-
Used along joints, corners and around penetrations before waterproofing membranes are applied
How to Choose the Right Waterproofing Solution at Bunnings
Choosing the right waterproofing product depends on the surface you’re protecting, the level of exposure to water and whether the area is interior or exterior.
Step 1: Define the Project Type
Ask yourself:
-
Is it a bathroom or shower?
-
An outdoor deck or balcony?
-
A concrete slab or planter box?
Your project dictates the type of product you need.
Step 2: Check Surface Material
Different substrates require different solutions:
-
Concrete, render or masonry: primers plus membranes
-
Wet areas inside: waterproof membrane systems
-
Outdoor paving: pond or concrete sealers
Step 3: Decide on Coverage and Thickness
Waterproofing coatings need to be applied thickly and evenly:
-
Check product coverage rates (m²/L)
-
Plan for at least two coats for effective protection
Step 4: Include Accessories
For best results:
-
Use bond breaker tape and joint sealants at internal corners
-
Reinforcing fabric in transition areas can improve flexibility
Step 5: Prioritise Safety and Conditions
Apply waterproofing only when:
-
Surfaces are dry, clean and free from dust
-
Weather conditions are suitable (especially for exterior coatings)
