Driveway Painting vs Sealing: Which Does Your Brisbane Driveway Need?

People often use paint and sealer as if they were the same thing. They are not, and there are several options in between.

Not every sealer is glossy. Penetrating sealers are designed to soak in and leave the surface looking close to natural, while film-forming products sit on top and may change the colour or sheen. Manufacturer descriptions make this distinction clearly.

Not every concrete paint is suited to cars or full sun either. A driveway carries hot tyres, turning wheels and strong UV, so a product needs to be rated for vehicle traffic and exterior exposure. Generic indoor floor epoxies are not automatically a good fit outdoors.

• Plain concrete: the widest range of options, from clear sealers through to coloured coatings.
• Exposed aggregate: usually suited to clear sealers that show off the stones; a solid colour coating would hide them.
• Stamped or stencilled: often previously sealed, so the existing product and its condition guide what can go on next.
• Already painted: the old coating must be well bonded, or removed, before anything else is applied.

Most driveway finishes fail because of what was underneath, not the product itself. Key preparation questions include:

• Oil and fuel stains: these can stop a coating bonding and usually need pre-treatment.
• Mould and algae: common in shaded Brisbane driveways and must be cleaned off thoroughly.
• Failing old finish: peeling or powdery coatings generally need removing first.
• Compatibility, adhesion and moisture: a new product must suit the old surface and the slab must be ready for it.
• Whole surface or spot clean: a full clean gives the most even base for a new finish.
• Repairs: cracks, lifting and broken edges should go to a concreting specialist before finishing.
• Colour, sheen and grip: a test patch helps confirm the look, and slip resistance additives are worth discussing for slopes.

A coating or sealer will not repair structural cracks or a slab that has settled. Deep oil stains can be reduced but there is no honest guarantee that every mark will disappear, and no finish is permanently non-slip. Being clear about these limits up front avoids disappointment later.

Every driveway is different, so a proper quote is needed rather than a generic price. The main factors are:

• Size of the area and any paths or crossovers included.
• Access for equipment and water.
• Whether an old coating needs removing.
• Any repairs needed beforehand.
• The system chosen, such as clear sealer or coloured coating.
• How long the driveway can be out of use.

Cure and return-to-traffic times are set by the specific product, temperature and humidity, so there is no single number to plan around. Dulux, for instance, gives product-specific cure guidance for its water-based concrete sealer. Expect to park elsewhere for a period and keep an eye on rain forecasts around the job date.

Regular sweeping, prompt cleanup of oil drips and an occasional gentle wash help any finish last longer. Tyre turning areas and the crossover usually show wear first. There is no universal resealing interval; when water stops beading or colour starts to wear, it is time to have it looked at.
