Once a driveway, path or paver is properly cleaned, a sealer keeps it that way — slowing down oil penetration, blocking algae regrowth, and stopping salt from working into the pore structure. We apply the right sealer for the surface, not whatever's cheapest by the drum.
- Penetrating sealers for salt and moisture resistance
- Topical sealers for a semi-gloss or wet-look finish
- Driveways, paths, pavers, pool surrounds and masonry
- Always applied to a dry, properly-prepared substrate
- Edges taped, overspray controlled, coats at spec rate
- Best paired with a professional pressure clean beforehand
Why it matters on the Northern Beaches
Concrete and paver surfaces near the coast are fighting three things at once — salt carried in on the wind, UV, and constant biological growth from a warm humid climate. Unsealed concrete draws salt and moisture deep into the slab where it then cycles between wet and dry, causing micro-cracks and spalling over years. Unsealed pavers lose their jointing sand, move under load, and collect grime in the pore structure that won't ever fully clean out once it's been there a couple of seasons. A sealer slows all of that down — it's preventative rather than cosmetic.
Our process
We only seal onto a clean, dry substrate — usually 24 to 48 hours after a proper pressure clean, depending on weather and how porous the concrete is. Shortcut that and you trap moisture, biological matter or residual soap under the coating, which is how you get a cloudy, blotchy finish that peels within a year. We use either a penetrating sealer (soaks in, reacts with the substrate, leaves almost no visible change but gives strong water and salt resistance) or a topical sealer (sits on top, gives a semi-gloss or wet-look finish, stronger stain resistance but needs re-coating more often). Which one is right depends on the substrate, the use case and the look you want — we'll walk through both options before committing to a product.
What can go wrong if it's done rough
Sealer applied to damp concrete goes milky. Sealer applied too thick pools and peels. Sealer applied over old incompatible coatings delaminates. Sealer applied without taping off walls, edges and grass gives you a yellow tideline wherever it runs. We do the prep properly and apply at the manufacturer's spec rate — not heavier, not lighter. Taped edges, controlled overlap, and only as many coats as the product calls for.
When to book it in
Immediately after a fresh pressure clean is the ideal window — the surface is at its cleanest and there's no rebuild of grime underneath the sealer. For most residential driveways a re-seal every three to five years is enough, longer for penetrating sealers on lightly-used surfaces. Commercial and strata concrete on heavy traffic usually sits on a shorter cycle. Pair it with a driveway cleaning visit and we'll sequence the two properly.
