Exposed aggregate sealing · Queenstown & Wanaka
Exposed aggregate sealing, that brings out the stone.
Exposed aggregate is the textured concrete finish you see on most Queenstown driveways and patios — concrete poured with the surface stones left visible. We seal it with penetrating chemistry that enhances the natural colour, locks out moisture, and protects against the freeze-thaw cycles that pull the stones loose from unsealed surfaces.
Aggregate we seal
Every aggregate surface needs the right sealer.
Aggregate driveways
The most common application — and the one where sealing matters most. Tyre traffic, oil drips, frost cycles and UV all attack unsealed aggregate. Sealing locks the surface and dramatically extends its appearance lifespan.
Aggregate patios
Outdoor entertaining areas where the aggregate texture is part of the design. Sealing brings out the natural stone colour and stops the matrix between stones from eroding.
Pool surrounds
Aggregate around pools needs a sealer that handles chlorine and repeated wetting without affecting slip-rating. We choose products formulated specifically for that environment.
Commercial forecourts
Café terraces, retail entrances and commercial alfresco areas. Sealed aggregate handles foot traffic and cleaning routines better than unsealed.
Reseal of older aggregate
Aggregate sealed years ago and now looking tired can usually be re-coated. We assess what's there, deep-clean it, and apply a fresh penetrating seal.
New aggregate after install
Sealing within the first month after the 28-day cure protects the surface from its first winter. Builders increasingly include sealing in the handover spec.
How we work
Slow when it matters, fast when it doesn’t.
01
On-site assessment
We come and look at the surface in person. Identify the substrate, test a small area, and work out what the surface actually needs.
02
Tailored method
Soft wash, steam, mild alkaline cleaner, biocide treatment, chosen for your surface, not from a one-size-fits-all playbook.
03
Careful application
Low-pressure equipment that won't damage the substrate. Plant protection. Spot-testing as we go.
04
Optional sealing
Once clean, a breathable sealer extends the result and protects against future moss, salt and water damage.
