Bunnings Garage Floor Epoxy Compared: What You Get, and What’s Missing

Short answer: Bunnings sells two genuine two-pack garage floor kits, Rust-Oleum EpoxyShield and Dy-Mark Epoxy Coat, from about $170 to $380. Both come with an etch and decorative flakes. Neither includes a primer or a clear top coat, and both are designed as a single colour coat. That is a fair product for a light-duty floor. For a garage where a car parks every day, the missing primer and top coat are the difference that matters. Here is what each option actually contains, what it costs to fill the gaps, and when a complete kit is worth the extra.

Two-pack vs one-pack: check for a hardener

To be fair to Bunnings: EpoxyShield and Dy-Mark Epoxy Coat are real two-pack epoxies - a resin and a hardener mixed just before use that cure by chemical reaction. They are not "fake epoxy". The one-pack products are a different thing: paint that dries as a film on top of the slab. Some are labelled "epoxy" because they contain epoxy resin, but with no separate hardener they dry like paint and wear like paint. The quick test on the shelf: no hardener, no true epoxy. Our paint vs epoxy guide explains why one-pack products struggle under car tyres.

What is in the box, and what is not

A durable garage floor is a system of layers, not a single coat. Here is how the two-pack kits compare with ours, layer by layer.

The two layers that matter are the primer and the clear top coat. The primer soaks into the concrete, seals it and gives the colour coat something to bond to; without it, the colour coat is doing the job of both. The clear top coat is the wearing surface - it takes the tyres, oil and dropped tools so the colour underneath does not. Rust-Oleum itself recommends adding a clear top coat over EpoxyShield.

Why DIY garage floors fail (it is rarely the product)

Read owner reviews of almost any garage coating and the same failure shows up: the coating peels or lifts, often in the wheel tracks where tyres turn and park. It nearly always traces back to one of four things:

• Prep was rushed. Epoxy will not grip smooth, dusty or oily concrete. Both Bunnings kits include an etch for this reason - the failures come when it is skipped, rushed or not rinsed and dried properly. Oil stains need a degreaser first.
• The slab was damp. Moisture rising through concrete pushes coatings off from underneath. Before you start, tape a 1 m × 1 m plastic sheet to the floor overnight; if moisture beads underneath, solve that first.
• One coat is a thin build. A single colour coat on bare concrete, with nothing on top, has the least material between your tyres and the slab.
• Coverage ran thin. Porous concrete soaks up more than the label suggests. A kit sized for exactly your floor area can run short at the far end, so size up if the slab is porous.

When a Bunnings kit is the right call

Honestly, often. For a shed, a laundry, a workshop corner or any floor a car never sits on, a Dy-Mark two-pack at $172 (single-garage size) with its included etch, done carefully, is a reasonable buy. If the floor is decorative and the traffic is light, even a paving paint can be fine - just go in knowing it is paint, not epoxy, and that it will need redoing.

What a complete kit changes

Our garage floor kits exist for the floor a car lives on. The difference is not "better epoxy" - it is the layers the single-coat kits leave out:

• Primer, colour and clear coat in one box. An epoxy primer to seal and bond the slab, a two-pack polyurethane colour coat, flakes (flake kit), and a two-pack polyurethane clear top coat. The colour and clear coats are UV stable, so the kits suit outdoor areas as well as garages.
• Time to get it right. Each coat has about an hour of working time at 25 °C and rolls on with an ordinary paint roller.
• Sized to your floor. Two sizes: 0-20 m² (covers about 15-20 m²) and 20-40 m² (about 35-40 m²). A single garage is typically 18-21 m², so measure first - and size up if you are close to 20 m² or the slab is porous.
• Instructions and a phone number. A step-by-step install guide, technical data sheets for every product, and phone support from people who lay these floors.

One customer, reviewing our flake kit after using a Bunnings kit at a previous home: "the kit contains everything you need and is much easier than a Bunnings kit which we used at our old place."

The cost, layer for layer

Materials for a single garage of about 20 m², at the prices above. All options also need rollers and brushes.

So the real comparison is not $172 against $499. Once you add a top coat to a Bunnings kit, the gap is about $60-90 - and the complete kit adds a primer, more working time and someone to call. Our kits ship free Australia-wide.

FAQ

Is Bunnings garage floor epoxy real epoxy?

Some of it. Rust-Oleum EpoxyShield and Dy-Mark Epoxy Coat are genuine two-pack epoxies with a separate hardener. One-pack floor paints, including some labelled "epoxy", are not - they dry as a paint film.

Do Bunnings epoxy kits include everything you need?

They include the etch, the colour coat and decorative flakes. They do not include a primer or a clear top coat, and like all kits they need rollers and brushes.

Why do DIY epoxy garage floors peel?

Usually preparation: the concrete was not cleaned, degreased and etched properly, or the slab was damp, so the coating never bonded. A thin single-coat build with no top coat makes it more likely. Any coating, retail or professional, fails on unprepared concrete.

Is a complete kit worth it over a Bunnings kit?

If a car parks on the floor, usually yes: the primer and clear top coat the single-coat kits leave out are what carry the wear, and once you buy a top coat separately the price gap is small. For a light-duty shed or laundry floor, a well-prepped Bunnings two-pack can be fine.
