Driveway Sealing Prices

Driveway sealing in Australia costs $300–$1,800+ depending on size and surface type. A standard 50m² concrete driveway costs $500–$850 to seal. Exposed aggregate sealing runs $8–$15/m², while asphalt sealcoating is the cheapest at $3–$8/m². All prices include GST.

Most concrete driveways should be resealed every 2–5 years depending on the sealer type and traffic levels. Acrylic sealers last 1–3 years, while penetrating sealers can last 5–10 years. Asphalt driveways should be sealcoated every 2–3 years. High-traffic or sun-exposed driveways may need more frequent attention.

DIY driveway sealing is possible for simple concrete or asphalt surfaces using roller-applied products from hardware stores. However, professional results are significantly better — professionals use commercial-grade sealers, proper spraying equipment, and thorough surface preparation. DIY is not recommended for exposed aggregate, stamped concrete, or natural stone.

Autumn and spring are ideal for driveway sealing in most Australian climates. You need 48 hours of dry weather with temperatures between 10–30°C for proper curing. Avoid sealing in winter (frost risk) or mid-summer (sealer cures too fast in extreme heat, causing bubbling).

Penetrating sealers soak into the concrete and protect from within — they do not change the appearance and are best for exposed aggregate and natural stone. Film-forming sealers (acrylic, polyurethane) sit on top and create a glossy or satin finish — they enhance colour but can peel or yellow over time. Each has its place depending on the surface type.

Sealing protects against water penetration, UV damage, oil stains, and surface deterioration, but it does not prevent structural cracking from ground movement or heavy loads. Existing cracks should be repaired before sealing. A well-sealed driveway is less likely to develop surface cracks from freeze-thaw cycles or moisture intrusion.

Stripping old sealer and resealing costs $15–$30/m² in Australia — roughly double the cost of a standard reseal. A 50m² driveway strip-and-reseal job typically costs $750–$1,500 including chemical stripping, surface cleaning, and two coats of new sealer. This is necessary when the existing sealer has failed, is peeling, or has turned white.

Yes. Sealing protects against water penetration, UV fading, oil stains, and surface erosion. An unsealed concrete driveway deteriorates faster and may need costly resurfacing ($80–$150/m²) within 10–15 years. Regular sealing every 2–5 years at $6–$15/m² per application extends the driveway lifespan by decades and maintains property value.

Yes, but moderately. Driveway sealing prices have risen 10–20% over two years depending on the sealer type. Petroleum-based sealers tracked oil price rises, while water-based acrylics increased only 3–5%. For 2026–2027, expect a further 2–4% increase. Booking in the off-season (autumn or late winter) and getting multiple quotes remains the best way to manage costs.

Most sealers are touch-dry within 4–8 hours and safe for light foot traffic after 24 hours. Vehicle traffic should wait 48–72 hours depending on the product and weather conditions. Solvent-based sealers cure faster in warm weather but may bubble in extreme heat (35°C+). Water-based sealers need temperatures above 10°C and no rain for at least 24 hours after application.

The cheapest professional option is asphalt sealcoating at $3–$8/m². For concrete, a basic acrylic seal costs $6–$12/m². DIY is cheaper still — a 20-litre pail of roller-applied concrete sealer from a hardware store costs $80–$150 and covers 40–60m². However, DIY results are less durable and may void any existing surface warranty.

Yes — surface cleaning is essential for proper sealer adhesion. Professional sealers pressure wash at 3,000–4,000 PSI to remove dirt, moss, oil, and loose material. This is usually included in the quoted price. If you do it yourself before the sealer arrives, you can save $2–$5/m² on the total quote, but the surface must be completely dry (24+ hours) before sealing begins.
