Worn, stained or patchy concrete does not always need to be ripped out. Resurfacing can give a driveway, path or patio a new finish for less than replacement, as long as the concrete underneath is sound.
When resurfacing works
- Surface wear, scaling or dusting.
- Stains and discolouration.
- Minor, stable hairline cracks.
- Wanting a new look on structurally sound concrete.
When resurfacing will not work
- Wide or moving cracks: they will come back through any new surface. See fixing cracks in concrete slabs.
- Sinking or lifting slabs: the ground underneath has a problem.
- Drainage problems: ponding or water running toward the house needs levels fixed, not a new coat.
- Spalling with exposed steel: that is concrete spalling and needs repair first.
Resurfacing options
Polymer-modified overlays
A thin cement-based layer bonded to the old concrete, finished smooth, textured or patterned.
Spray-on and stencil finishes
Decorative coatings sprayed over a stencil to create tile, brick or stone patterns.
Grind and seal
The surface is ground back to clean concrete, then sealed. Suits patios and garages where the concrete is in good condition.
Coatings and sealers
Colour coatings and sealers that refresh the look and protect against stains.
Preparation decides the result
Resurfacing fails when the surface is not properly cleaned and prepared, or when underlying cracks and drainage are ignored. Proper preparation, crack treatment and control joints carried through to the new surface make it last.
Resurface or replace?
If the slab is structurally sound and drains correctly, resurfacing is usually the economical choice. If it is cracked through, moving or draining the wrong way, replacement is often better value over the long run. Our concrete driveway cost guide covers what replacement involves.

Frequently asked questions
Can you resurface a cracked driveway?
Only if the cracks are minor and stable. Wide or moving cracks come back through a new surface and need repair or replacement.
How long does concrete resurfacing last?
It depends on the product, preparation and traffic. Good preparation over sound concrete gives the best life.
Is resurfacing cheaper than replacing concrete?
Usually, when the existing slab is sound. If it is cracked through or sinking, replacement is often better value.
