Resurfacing Concrete Flooring

Updated November 2025

For close to 30 years we have proudly been installing the X-Bond concrete floor overlay to projects throughout Australia in residential, commercial, retail, hospitality and educational spaces. So it’s safe to say, we know a thing or two when it comes to concrete resurfacing!

As industry trends shift toward sustainability and convenience, materials that provide both are in high demand. The design world is catching up to what we already knew when we started Alt. in 1999 — that microcement is an innovative solution to remodelling old concrete surfaces without the need for their removal, saving time and reducing project waste.

X-Bond Microcement flooring — applied to replicate concrete.

Why a microcement overlay may be perfect for resurfacing your concrete floor…

Open up Instagram or Pinterest and you’re almost guaranteed to see a photo in your feed that features some type of concrete aesthetic. Whether it’s on the floors, walls or joinery, concrete is a modern yet timeless material to use. With microcement overlays, it’s easier than ever to achieve that concrete texture everyone loves, and it’s more achievable than you think.

A concrete overlay is perfect for clients who:

• are unable or don’t want to pour a new slab of concrete

• don’t like the look of their existing concrete floor

• want to replace old tiles or timber flooring

• want to save time and costs involved with removing their existing floor

If you answered yes to any of the above, then you’re in the right place!

At Alternative Surfaces we’ve used X-Bond for concrete resurfacing on residential and commercial flooring.

How is microcement applied onto concrete?

The X-Bond concrete overlay flooring system is applied directly over an existing substrate. It is installed using a hand trowel by our team of experienced professionals. The cement based mix is applied at approximately 3mm thick over an existing concrete slab, over existing tiles (yep, ugly old tiles be gone!) and over compressed sheeting.

What’s the difference between concrete and a concrete overlay?

Great question! A concrete overlay is a thin coating that’s hand applied over a concrete slab or other surface. It is not as thick as concrete and while it isn’t as strong, it’s still very durable. It has the added benefit of being more flexible than rigid concrete, and therefore less prone to cracking. Concrete overlays are also usually warmer under foot, and provide more design options in terms of colour and texture.

Can a concrete overlay be applied over in-slab heating?

Our concrete overlay system, X-Bond, can be applied over in-slab heating. First a thin screed would need to be applied directly over the heating, and then the X-Bond would be hand trowelled on top.

What colours and finishes are available?

Within our X-Bond range there are four different texture finishes and 10 standard colours available. Click the button below to find out more.

Frequently Asked Questions

• What's the difference between microcement and concrete?

  Microcement is a thin, decorative coating (2–3 mm thick) made from cement, polymers, and colourpigments, applied over existing surfaces for a seamless finish. Concrete, on the other hand, is a structural material poured thick to form foundations or slabs.

  Microcement can give you the look of concrete without the weight, cracking risk, or installation complexity — perfect for bathrooms, walls, and furniture.

• What other surfaces can microcement go over?

  Microcement can be applied over most stable, level, substrates — including concrete, tiles, screeds, plaster, cement board, MDF, and even existing stone benchtops. The key is proper preparation to ensure strong adhesion and prevent future movement or cracking.

• Can microcement be used outdoors?

  Absolutely. When sealed correctly, microcement performs well outdoors on patios, steps, and pool surrounds. UV-resistant sealers are essential for long-term durability and colour stability in external conditions.

• Does the existing concrete need to be in good condition before resurfacing?

  Yes — a sound, crack-free, and clean surface is crucial. Damaged or unstable concrete should be repaired or levelled before applying microcement or any resurfacing product, ensuring long-term adhesion and performance.
