Concrete sealing
What concrete sealing with us looks like
Unsealed concrete is porous. Oil, leaf tannin, rust and mould all soak in, and once they're in the surface they're hard to get out. A sealer slows that down and, on coloured and aggregate finishes, can bring back depth the sun has faded.
Every sealing job starts with a proper clean and time to dry. Then we apply a sealer chosen for the concrete and how you use it: a penetrating sealer for a natural look, or a topical sealer for a satin or wet look where it suits. We'll show you the difference before we start.
Why it matters
What you get
Stains stay on top
Oil and spills sit on the surface long enough to clean up.
Colour brought back
Coloured, stamped and aggregate finishes can be deepened if you want it.
Grip considered
Anti-slip additive on pool surrounds, ramps and steep driveways.
Easier to clean
A sealed surface cleans up with less pressure next time.

Our method
How we do it
Nathan is punctual, knowledgeable, polite and left our place neat and tidy.
Step 01 of 04
Deep clean
The concrete is cleaned and stains treated before any sealer goes near it.
He was professional, responsive, and delivered exactly as promised.
Step 02 of 04
Dry out
The surface is left to dry fully. Sealing damp concrete causes cloudy patches.
Great work, fair pricing, and excellent communication.
Step 03 of 04
Apply
The sealer goes on evenly by sprayer or roller, with an anti-slip additive where needed.
Excellent service! Nathan is punctual and nothing is a problem.
Step 04 of 04
Cure
The area stays closed for the product's curing time before cars or furniture go back.
Penetrating or topical?
A penetrating sealer soaks in and lines the pores. It doesn't change the look much, doesn't peel and suits plain concrete and areas where grip matters most.
A topical sealer leaves a film on top, from satin to a glossy wet look. It brings the colour up on aggregate and stamped concrete but wears in tyre tracks and needs recoating sooner. We'll recommend one for your concrete and how hard it's used.
Resealing over old sealer
If an old topical sealer is peeling or has gone white and cloudy, it needs stripping or rejuvenating before a new coat goes on. Sealing over a failed coat just traps the problem. We'll check yours and include it in the quote.

Nathan did an amazing job bringing our sandstone walls and path back to life. He was very polite and worked hard to make sure the entire job was completed to perfection.
Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.
Nathan provided a reliable and professional property maintenance. Great work, fair pricing, and excellent communication. Highly recommend!

Still have a question?
Talk to Nathan directly. He quotes and attends every job himself.
How long does concrete sealer last?
It depends on the sealer, the sun and the traffic. Penetrating sealers outlast topical ones on driveways, which wear under tyres. A water test shows when it's time to reseal.
Will sealed concrete be slippery?
Topical sealers can be, so we add an anti-slip additive on pool surrounds, ramps and sloping driveways.
Why has my sealed concrete gone white?
Usually moisture trapped under a topical sealer, or a sealer that has broken down. It can often be fixed by stripping or rejuvenating the coating.
Can you seal exposed aggregate?
Yes. A topical sealer can bring the colour of the stones back up, and it helps hold loose stones in place.
How long before I can drive on it?
It depends on the product and the weather. We'll tell you the curing time for the sealer we use, and keep the area closed until then.
Do you clean before sealing?
Always. Sealing over dirt, mould or oil locks them in.
