7 Things We Assess Before Resurfacing a Sports Court

The underlying foundation determines how a court behaves under thermal expansion, heavy foot traffic and moisture exposure. Before planning any coating system, we determine whether your court is built on an asphalt or concrete base.

• Asphalt substrates: Over time, asphalt oxidises under Sydney's harsh sun, leading to surface ravelling and loss of flexibility. We evaluate the binder integrity to ensure the asphalt isn't crumbling beneath the surface.
• Concrete substrates: Concrete requires careful evaluation for vapour transmission, surface laitance and movement joints. Without specialised priming and mechanical profiling, coatings applied to concrete risk delamination and bubbling.

Not all cracks are created equal. During our assessment, we categorise surface defects into hairline shrinkage cracks, stress fractures or deep structural failures.

For routine court repairs across Sydney, we utilise specialised acrylic patch binders and flexible membrane systems designed to bridge minor movement. However, we maintain realistic expectations: resurfacing alone cannot permanently fix underlying sub-base subsidence or major active structural shifting. Identifying these limitations early prevents wasted investment and allows us to advise on the most practical long-term approach.

Understanding what is already on your court is vital. Has the court been previously restored using a professional acrylic system, or was it coated with an incompatible oil-based paint or silicone sealer?

Multiple layers of flaking paint or incompatible previous coatings impair adhesion. If existing layers are peeling or delaminating from the base, applying new acrylic coatings directly over them will cause the new surface to pull away. We test the existing surface's sound integrity to establish whether localised patching or complete mechanical grinding is required.

Sydney's weather patterns bring intense summer downpours and periods of lingering humidity. Water is the single greatest enemy of any outdoor sports surface.

During our assessment, we check for proper fall, localised depressions (often called 'birdbaths') and surrounding site drainage issues. Standing water breaks down acrylic binders, reduces traction and creates dangerous slippery zones. Identifying low areas allows us to level depressions using specialised acrylic levelling reserves prior to final resurfacing layers.

Surface preparation accounts for the majority of a successful resurfacing job. We assess the level of accumulated organic matter, moss, algae, oils and atmospheric grime present on the court.

Before any new acrylic court resurfacing application begins, the court must be thoroughly decontaminated. Our assessment establishes whether the site requires high-pressure industrial washing, chemical mould treatment or mechanical scarification to create a clean, porous profile that guarantees maximum coating adhesion.

How the court will be used dictates the texture, grit and resilience required in the resurfacing system. Different athletic disciplines demand distinct surface friction coefficients:

• Tennis court resurfacing Sydney: Requires a balanced, predictable pace and true ball bounce.
• Basketball court resurfacing: Demands exceptional traction for rapid directional changes, pivots and heavy footfall.
• Netball court resurfacing: Places supreme emphasis on non-slip safety during sudden stops to protect player joints.
• Multi-sport courts: Requires customised texture blends suitable for shared school and community recreational use.

The final step of our pre-resurfacing assessment is visual and spatial planning. Modern courts are no longer restricted to traditional green and blue palettes. We assess how two-tone keyway designs, contrasting perimeter borders and custom branding can elevate the asset.

For facilities adapting an existing slab for multi-sport use — such as combining basketball, netball and pickleball — we evaluate spatial dimensions to design a clear, colour-coded line hierarchy. This ensures boundaries remain intuitive and clean without creating visual confusion for players.
