A driveway sealer is a clear or tinted coating that soaks into or sits on top of concrete to block oil, water and stains and to make cleaning easier. Penetrating sealers keep a natural look, while epoxy and acrylic film sealers add gloss and colour but need more preparation.
Below you’ll find the sealer types compared, colour options, preparation steps, price ranges and the mistakes that make a sealed driveway peel.
Key points
- Choose a penetrating sealer for a natural, non-slip finish and a film-forming sealer for gloss, colour or a wet look.
- A clean, dry, fully cured slab matters more than the product you buy, because sealer fails where moisture or oil is trapped.
- Sealing a standard driveway commonly costs about $8–$25 per m² when a pro does it (indicative — get itemised quotes).
- Always follow the product label for mixing, ventilation, protective gear and recoat times.
Driveway sealer types: concrete driveway sealer compared
| Sealer type | How it works | Look | Best for |
|---|---|---|---|
| Penetrating (silane or siloxane) | Soaks into the pores and repels water | Natural, no sheen | Exposed aggregate and broom-finished slabs |
| Acrylic film sealer | Forms a thin protective layer on the surface | Satin to gloss | Stencilled or coloured concrete |
| Polyurethane sealer | Forms a harder, abrasion-resistant film | Satin to gloss | Driveways with heavy tyre traffic |
| Epoxy sealer | Two-part coating that bonds to the surface | Hard, glossy | Garage floors and protected, covered slabs |
| Concrete sealing paint | Pigmented coating that colours and seals | Opaque colour | Tired slabs that need a fresh look |
| Spray concrete sealer | Same chemistry applied with a pump sprayer | Depends on the product | Large areas and textured finishes |
Epoxy is tough indoors, but under direct sun it can chalk and yellow, so most outdoor driveways suit a UV-stable acrylic or polyurethane instead.
Sealing concrete driveway: step by step
- Check the slab age and make sure the concrete has fully cured, using the cure period on the product label.
- Remove oil and grease with a suitable degreaser, and repeat on stubborn tyre marks until water no longer beads on the stain.
- Clean the surface with a stiff broom and low-pressure wash; our how to clean concrete guide covers the safe methods.
- Let it dry completely, because damp concrete clouds many sealers and traps moisture under the film.
- Apply thin, even coats with a roller or low-pressure sprayer, and work in the shade or in the cooler part of the day.
- Keep traffic off until the label says it is safe, and keep rain, pets and leaves off the wet coat.
Concrete sealer for driveway: choose by finish
- Exposed aggregate: use a penetrating or low-sheen sealer that deepens the stone colour without turning the surface slippery; see exposed aggregate concrete.
- Broom or float finish: choose a satin acrylic sealer, which protects the surface and still gives grip when wet.
- Stencilled or stamped concrete: pick a UV-stable film sealer that revives the pattern; see concrete stencil and stencil concrete patterns.
- Old, stained or patchy slab: consider concrete sealing paint, which hides stains; see our driveway paint guide.
- Sloped driveway: add the anti-slip additive recommended on the label, since a glossy film becomes slippery in rain.
- Garage floor: choose a two-part epoxy only where the slab is covered, dry and well ventilated.
Driveway sealer colours and concrete sealer colors
| Colour option | Effect | Notes |
|---|---|---|
| Clear | Keeps the natural concrete colour | Shows slab patches and stains most |
| Wet-look clear | Deepens the colour of aggregate and stencil patterns | Can be slippery, so add anti-slip |
| Light grey or sandstone tint | Evens out patchy colour | Keeps surface temperature down in summer |
| Charcoal or dark tint | Modern, hides oil marks well | Shows dust and gets hot on western driveways |
| Terracotta or brown tint | Warm tone that suits brick homes | Test on a small patch to check the final shade |

Colour seal driveway: how to pick a shade
- Test a patch in a low-profile corner and let it dry fully, because tint looks darker when wet.
- Match the roof or fascia within one or two shades so the driveway does not fight the house.
- Choose lighter tints on north- and west-facing driveways to reduce heat and glare in summer.
- Consider oil stains: mid-tones disguise car drips better than clear or pale grey.
- Avoid very glossy finishes on slopes, which can become slippery when wet.
- Check the manufacturer’s range for tints that are rated for exterior vehicle traffic.
Seal driveway cost and recoat timing
| Item | Typical range | Notes |
|---|---|---|
| Penetrating sealer, professionally applied | $8–$18 per m² (indicative — get itemised quotes) | Longer recoat gap, lower gloss |
| Acrylic or polyurethane film sealer | $12–$25 per m² (indicative — get itemised quotes) | Needs more frequent recoating |
| Epoxy or sealing paint system | $25–$60 per m² (indicative — get itemised quotes) | More preparation and curing time |
| DIY sealer and tools | Product plus roller or sprayer hire (indicative — get itemised quotes) | Saves labour but needs correct preparation |
| Recoat | Typically every few years, depending on traffic and product | Follow the manufacturer’s guidance |
Concrete sealant for driveways: spray or roller?
- Pump sprayer: fast on large driveways, but back-roll film sealers so they do not pool in low spots.
- Roller: gives more control on textured slabs and keeps product off garden beds and walls.
- Brush: use it only along edges, expansion joints and around downpipes.
- Wind and shade: avoid spraying in strong wind, and mask nearby plants, cars and pavers.
- Safety: wear the protective gear listed on the label, and keep solvent-based sealers away from flames and poorly ventilated garages.
- Disposal: do not wash tools or leftover sealer into the stormwater drain; follow the label for disposal.
Common mistakes to avoid when using a driveway sealer
- Sealing damp or new concrete before it has cured, which causes milky patches and peeling.
- Skipping the degrease, so oil stains bleed through the new coat within weeks.
- Applying thick coats in one pass, which bubbles, whitens and dries unevenly.
- Using the wrong product on bare concrete, such as an indoor epoxy outside in direct sun.
- Forgetting grip on slopes and near the garage door, where a glossy film turns slippery in rain.
- Ignoring cracks, which let water under the film; repair them and fill joints first.
Driveway sealer FAQs
What is the best concrete sealer for a driveway?
For most Sydney driveways, a UV-stable acrylic or polyurethane film sealer, or a penetrating sealer for aggregate, works best. Choose the product by slab finish and traffic, and check the label for exterior vehicle use. Epoxy sealers suit covered garage floors better than open driveways.
Can I use a spray concrete sealer myself?
Yes, if the slab is clean, dry and cured. Use a low-pressure pump sprayer, follow the label for coats and recoat time, and wear the listed protective gear. Back-roll film sealers to avoid puddles, and skip spraying on windy days.
Does sealed concrete need resealing?
Yes. Traffic, sun and cleaning wear the sealer down over time. Reseal when water stops beading on the surface or the finish looks dull. Penetrating sealers usually last longer between coats than thin acrylic films, but follow the manufacturer’s guidance for your product.
Is concrete sealing paint the same as a sealer?
No. Sealing paint is a pigmented coating that hides stains and changes the colour, while a clear sealer protects the surface and shows the natural concrete. Paint needs thorough preparation and an anti-slip additive, and it can peel on old, oily slabs if the preparation is rushed.
