Concrete and Driveway Sealing
Sealing is one of the simplest ways to protect outdoor concrete and bring back its colour. A good sealer helps resist oil and food stains, reduces dusting, makes cleaning easier and can deepen the tones of exposed aggregate and coloured concrete. Rowville Concrete quotes pressure cleaning and sealing for driveways, paths, patios and pool surrounds across Rowville and nearby suburbs, as well as sealing newly poured concrete once it has cured.
Why seal concrete?
- •Stain resistance. Sealed surfaces resist oil, grease, food, drinks and garden products for longer, giving you time to clean up spills.
- •Colour enhancement. Sealers can bring out the colour of exposed aggregate stones and coloured concrete, from a natural look to a "wet look".
- •Easier cleaning. A sealed surface sheds dirt more easily and needs less scrubbing.
- •Reduced dusting and wear. Sealers help bind the surface, reducing dusting on garage floors and patios.
- •Moisture and weathering protection. Sealers reduce how much water and dirt the concrete absorbs, which helps with mould and moss in damp areas.
Types of sealers
Sealer choice depends on the surface, the look you want and how the area is used.
Penetrating sealers
These soak into the concrete and react within the surface to repel water and stains without changing the look much. They suit plain concrete and areas where a natural finish is wanted.
Film-forming (topical) sealers
These form a thin protective layer on top of the concrete. They're commonly used on exposed aggregate, coloured and stencil surfaces, and come in matt, satin and gloss finishes. They enhance colour but wear over time and need reapplication.
Tinted or colour sealers
These contain pigment to refresh or change the colour of existing concrete. They're a popular way to revive faded coloured driveways or even out patchy grey concrete.
Anti-slip additives
Fine grit can be added to sealers to improve grip, particularly on sloping driveways, steps and pool surrounds.
The sealing process
- 01Assessment. We look at the surface, any existing sealer, stains, cracks and how the area drains.
- 02Pressure cleaning. The surface is cleaned thoroughly to remove dirt, moss, mould and loose material. This step makes a big difference to how the sealer looks and bonds.
- 03Stain treatment. Oil and rust stains are treated where possible. Some deep stains may lighten but not disappear entirely.
- 04Repairs. Minor cracks can be filled before sealing. See crack repairs.
- 05Drying. The concrete needs to be dry enough for the chosen sealer.
- 06Application. The sealer is applied evenly by roller or sprayer, often in two coats, with anti-slip additive if selected.
- 07Curing. The area is kept clear of foot traffic and vehicles until the sealer has cured, as advised for the product.
Sealing new concrete
New concrete needs time to cure before most sealers can be applied, and the timing depends on the product and weather. Many new exposed aggregate, coloured and stencil surfaces are sealed as part of the original job. See exposed aggregate driveways, coloured concrete driveways and stencil and stamped concrete.
Resealing existing surfaces
Film-forming sealers wear, especially in sun and in tyre paths. Signs that it's time to reseal include:
- •water soaking in rather than beading;
- •colours looking dull and chalky;
- •stains soaking in quickly;
- •visible wear patterns in high-traffic areas.
Resealing usually involves cleaning and a fresh coat compatible with the existing sealer. If the old sealer is peeling, cloudy or flaking, it may need stripping first.
Sealing garage floors, sheds and workshops
Inside garages and sheds, the priorities are different. Dusting from bare concrete settles on everything stored nearby, and oil, brake fluid and paint drips leave marks that are hard to shift from unsealed floors. A penetrating sealer or a clear topical sealer suited to vehicle traffic reduces dust and makes spills easier to wipe up. Hot tyres can soften or lift some topical products, so the choice of sealer for a garage matters. For new floors, see our garage slabs and shed slabs pages.
What sealing can't fix
Sealing protects and enhances, but it won't fix structural problems. Sinking slabs, wide cracks, drainage faults and badly spalled surfaces need repair or replacement. See concrete resurfacing and driveway replacement.

Concrete sealing FAQs
It depends on the sealer type, sun exposure and traffic. Watch for water soaking in, dull colours and stains setting quickly. Those are signs it's time.
Some glossy sealers can reduce grip when wet. Anti-slip additives and matt or satin finishes help, especially on slopes and around pools.
Many oil stains can be reduced with treatment, but deep, old stains may not disappear completely. Sealing afterwards helps prevent new stains soaking in.
A tinted sealer can refresh or shift the colour of existing concrete. It sits on the surface, so it will wear over time and need reapplication.
Sealing is commonly done on exposed aggregate to enhance the stones and protect the surface. It's usually applied after the concrete has cured.
