What Is Concrete Resurfacing? Everything You Need to Know
Concrete is one of the most widely used construction materials in the world, popular because of its strength, durability, and rugged minimal vibe. However, even the toughest surfaces can show signs of wear over time — whether it’s cracking, surface deterioration, discoloration and staining, or general fatigue.
Fortunately, replacing old concrete with a brand new slab isn’t always necessary. Concrete resurfacing provides an effective way to restore and enhance existing concrete without the cost, mess, or downtime of its demolition. In this article, we’ll explore what concrete resurfacing involves, how materials like microcement are making it easier, and when it’s the right choice for residential or commercial projects.
What Is Concrete Resurfacing?
Concrete resurfacing is the process of applying a new surface layer — typically a cement-based or polymer-modified compound — over structurally sound existing concrete. This technique covers imperfections, improves durability, and offers the opportunity to create decorative finishes that elevate the overall aesthetic.
Rather than tearing up the old slab, resurfacing with an overlay transforms the appearance and performance of concrete while keeping the base intact (which is why it only works on stable substrates). It's suitable for a range of interior and exterior applications, from driveways and patios to commercial flooring and retail spaces.
How Does Concrete Resurfacing Work?
The success of a resurfacing project relies on proper preparation and skilled application. Here's how the process typically unfolds.
Assessment of the Existing Slab
The concrete must be structurally sound. Intense cracks, frequent movement, or moisture damage may render the surface unsuitable for resurfacing.
Surface Preparation
All debris, oil, coatings, and contaminants are removed. Cracks and minor surface damage are repaired to ensure a stable base. If dealing with extensive damage, a skilled surfacing professional is your greatest asset. They can plan and action the restoration work needed to ensure a lasting end result.
Waterproofing and Priming (if required)
Depending on the resurfacing system and the environment, a primer or bonding agent may be applied to ensure strong adhesion. In areas prone to water exposure such as balconies or pool surrounds, a waterproofing membrane may also be applied over the old concrete before resurfacing. T
Application of the Resurfacing Material
The resurfacing material is installed. There are a range of overlays on the market, but X-Bond Microcement is our top choice. It’s applied by hand with a trowel in thin, lightweight layers — adding minimal height and weight to the existing concrete, but giving it a totally new look (and holding up under decades of wear).
Sealing
A high-performance sealer is applied to protect against stains, impact, UV exposure, and moisture ingress.
Where Can Concrete Resurfacing Be Used?
Concrete resurfacing is a great alternative to demolition in renovations of both interior and exterior environments, including:
Driveways and footpaths
Patios and courtyards
Pool surrounds
Garage floors
Commercial spaces — from offices and retail stores to schools and hospitality venues
Industrial and warehouse flooring
Microcement: A Premium Resurfacing Material
One concrete resurfacing option that’s gained considerable traction in recent years is microcement; a modern, high-performance coating applied in ultra-thin layers over a range of existing substrates (not just concrete!).
Like concrete, microcement is valued for its organic architectural appeal and ability to create seamless, tactile surfaces across multiple zones.
But what sets microcement apart?
Minimal thickness (typically 1/8”)
Seamless finish similar to concrete
Highly customizable in terms of texture and color
Suitable for floors, walls, bathrooms, benchtops and wet areas
Exceptional bonding to the existing substrate
Durable finish that holds up in high-traffic areas and UV exposure
Design-forward aesthetics for contemporary projects
Microcement is popular as a modern, low-maintenance finish for commercial renovations and high-end homes alike, where the design impact of minimalist, textured surfaces is key.
From luxury hotel chains and bustling hospitality spaces to residential exterior remodels, our product X-Bond Microcement has been trusted in concrete resurfacing projects since 1991.
Key Benefits of Concrete Resurfacing with X-Bond
The top reasons clients choose X-Bond for their resurfacing projects are that it’s:
Cost-Effective – A practical alternative to removing and replacing old slabs
Time-Saving – Faster turnaround with less disruption to occupants
Sustainable – Reuses the existing base, reducing waste
Highly Durable – Resistant to traffic, weather, and surface wear when properly sealed
Visually Transformative – From classic concrete grey to textured stone-like finishes, the design options are vast
These benefits are amplified due to the addition of Liquid Membrane in the X-Bond installation system, providing waterproofing and anti-fracture protection that not only enhances long-term durability but also provides a level of flexibility and moisture resistance that traditional resurfacing systems often lack.
By isolating surface movement and protecting against minor substrate cracking, Liquid Membrane acts as a crucial intermediary layer that reinforces the integrity of X-Bond, particularly important in high-traffic or moisture-prone environments.
When Is Resurfacing the Right Option?
Concrete resurfacing with microcement is ideal when:
The existing slab is structurally sound (no major cracking or moisture problems)
The goal is to improve aesthetics or functionality without replacing the entire surface
You want a faster, cleaner solution than full demolition and re-pouring
A decorative or architectural finish is desired
In the event that the concrete has extensive structural damage or issues with rising damp, but your heart is set on a fresh X-Bond surface, it may require remediation or replacement before application can occur.
How Long Does Resurfaced Concrete Last?
With proper preparation and a quality product like X-Bond, resurfaced concrete can last 10 to 15 years or more before you have to consider re-sealing.
Concrete resurfacing is a smart, resourceful way to restore or enhance your space, whether it’s a driveway that’s seen better days or polished concrete internal flooring in need of a refresh. For those seeking a more architectural or contemporary aesthetic that’s in the same realm as concrete, microcement provides a premium option that blends performance with refined design. You can extend the life of your surfaces while reducing time and mess, while enjoying exceptional flexibility in terms of finish and application.
