If you’re researching concrete resurfacing, you might first be wondering: what exactly does it involve? If you’re researching concrete resurfacing, you might first be wondering: what exactly does it involve? With more renovation projects in 2026 focused on upgrading existing surfaces rather than full replacement, it’s a question we’re hearing more often.

Essentially, concrete resurfacing encompasses any process of replacing an old concrete slab. You’d be considering this option if you have discoloured, damaged or cracked concrete. There are multiple ways to do this, and we’ll take you through them in this article. Each comes with different implications for cost, durability, and installation process.

One thing to get out of the way — we don’t recommend simply pouring new concrete on top of the old. Any surfacing professional will tell you this isn’t a good idea! A new concrete slab won't properly adhere to the surface beneath it, because concrete doesn’t contain any bonding agents in its formula. This brings you back to where you started; with concrete in bad condition.


How to Resurface Concrete

  1. Re-Lay a new slab

Replacing a damaged concrete slab with a brand new one is the most traditional resurfacing method. This would mean ripping out the old concrete and having it completely re-laid from start to finish.

The downside of this is that the costs of demolition can add up — not to mention it’s a time consuming process, involving both removal of the existing surface and installation of the new one.

2. Install a concrete overlay

Looking for a newer, more innovative way to resurface? Concrete overlays are the answer. This refers to any surfacing material that can be applied straight over the existing concrete. It’s faster and easier than re-laying a new slab, as it doesn’t involve any demolition.

Concrete overlay systems usually consist of sand, cement, liquid polymer and colour pigment all mixed together. The polymer is what allows them to adhere to the surface underneath, unlike concrete (as mentioned above).

Overlay systems are our speciality, and we’ve been supplying advanced overlay solutions to installers around Australia for 25 years. Read more about how concrete overlays work.

3. Use microcement

One of the most popular concrete resurfacing overlays among designers, builders and home owners is microcement. Microcement is applied as a thin coating on top of the existing concrete slab — as well as a range of other substrates, too. Our product X-Bond has been used in literally thousands of resurfacing projects over 25+ years.

Ultimately, microcement will achieve a similar look to concrete with more advantages. It’s just as strong and durable, but has an easier installation process, a wider range of applications, and more versatile design options.

4. Fix cracks with an anti-fracture membrane

Sometimes all you need is an anti-fracture membrane to fill in the cracks, and your damaged concrete surface is fixed. For small fractures, especially where water leaks are an issue, this is an easy DIY solution. Learn more about our advanced anti-fracture and waterproofing membrane, Liquid Membrane.

If you’re choosing to resurface concrete with an overlay, it needs to be in good condition. Any damage or cracks must be stabilised anyway with an anti-fracture measures. Our Liquid Membrane is one of the most advanced on the market. We train installers to apply it over any cracks to prepare a strong base for microcement application.

More intense damage would also need to be repaired in preparation for any overlays. See this in action to transform an old pool coping.

5. Concrete Colour Stain

If you just want a new colour for your concrete, completely replacing or overlaying the slab might be too extreme. There’s a much simpler solution if aesthetics are your only problem: concrete stains.

Our Concrete Colour Stain can change the colour of concrete, no matter how old it is. Because of its translucent water-based formula, it etches onto a concrete surface without totally covering its textural characteristics — great news for raw concrete lovers.

Through advanced engineering, this formula is provides a long-lasting colour finish by penetrating deep into the pores of the concrete. In addition, it also solidifies crumbling surfaces — so if you have a slightly damaged concrete slab and you want to refresh its colour, this is a great solution. Concrete stains are known for producing subtle, earth-toned shades that blend well with natural surroundings. It that’s your vision, Colour Stain is perfect.

10 Reasons We Recommend Microcement for Concrete Resurfacing

  1. Renovations are a lot easier when you can remodel your surface without removal. By applying microcement by hand straight over the top of the old concrete, you can save yourself the costs and time of demolition. Did you know it can also be used for tile resurfacing?

  2. Unlike alternatives like epoxy, microcement stands out for its versatility — suitable for both internal and external applications. While most concrete resurfacing products are limited to either one, microcement offers consistency in finish and colour from indoor to outdoor spaces.

  3. X-Bond Microcement is applied at a depth of only 3mm over existing concrete, enabling a broader scope of use beyond traditional flooring or wall surfaces. Our expertise extends to intricate projects such as concrete staircases, joinery, and pool copings.

  4. The minimal thickness also ensures no added height to your existing surface, making it the most seamless choice for concrete replacement.

  5. When paired with our waterproofing membrane, X-Bond Microcement becomes suitable for wet areas like pool decking, bathrooms, and exterior surfaces exposed to the elements.

  6. Microcement is a low-maintenance finish. Periodic wiping or hosing down with water and following our simple maintenance guidelines will keep it looking great.

  7. Microcement seamlessly integrates with underfloor heating, the primary choice for concrete flooring heating systems.

  8. Our X-Bond Microcement is also more durable than other overlay systems, thanks to added latex polymer for unmatched flexibility. The risk of cracks and delamination is greatly reduced. In fact, we’ve never had a delamination issue in almost three decades.

  9. Originally invented as a concrete alternative, X-Bond offers a remarkably similar appearance to traditional concrete down to the slightly textured, imperfect finish.

  10. For diverse design possibilities, the X-Bond range offers a range of colour and texture options suitable for concrete resurfacing.

FAQs About Microcement for Concrete Resurfacing

Can you apply microcement over damaged concrete without removing it?

In many cases, yes — microcement can be applied over cracked concrete, provided the substrate is stable and properly prepared. Cracks are typically treated and reinforced before application to minimise the risk of them reflecting through the new surface.

Topical damage like surface stains generally require minimal preparation; after thorough cleaning, standard grinding is usually sufficient. However, it’s important to identify and if needed address the underlying cause of staining (e.g. water leaks) to prevent future issues.

How long does microcement last on outdoor concrete surfaces?

When installed and sealed correctly, microcement can las decades on outdoor surfaces. Its durability depends on factors like exposure to weather, foot traffic, and ongoing maintenance, but it is designed to perform in exterior environments.

Is microcement suitable for resurfacing concrete driveways or high-traffic areas?

Microcement can be used in high-traffic areas, but not all systems are suitable for driveways. It’s important to use a system specifically designed for heavy loads and exterior conditions, and to ensure proper installation.

Do you need to prepare concrete before applying microcement?

Yes, surface preparation is critical. The concrete must be clean, stable, and free from contaminants. This may involve grinding, repairing cracks, and applying primers to ensure proper adhesion.

Can microcement be used to resurface concrete around pools?

Yes, microcement is commonly used for pool surrounds when paired with the correct waterproofing and slip-resistant finish. It provides a seamless look and can handle exposure to water and outdoor conditions.

How much does it cost to resurface concrete with microcement in Australia?

Costs can vary depending on the size of the area, condition of the substrate, and complexity of the project. In Australia, microcement is generally considered a premium resurfacing option, but it can offset costs by avoiding demolition and reducing labour time.
