Concrete cleaning and sealing in Wonthaggi

Why seal concrete on the coast

Sealing protects concrete from moisture, salt, oil and stains, slows colour fading and makes cleaning easier. On the Bass Coast, with salt spray, sea mist and sandy traffic, a good sealer makes a real difference to how long decorative concrete keeps looking good.

Cleaning first

We pressure-clean to remove dirt, mould, lichen, salt deposits and old flaking sealer, then let the surface dry before sealing.

Sealer types

Penetrating sealers soak in and leave a natural look. Acrylic sealers form a film that deepens colour and adds sheen. We recommend what suits the surface, exposure and how it is used.

Anti-slip

On slopes, paths and around pools, we add anti-slip grit to the sealer.

How often

Typically every two to five years, depending on traffic and exposure. Driveways close to the beach often need it sooner.

Sealing salt-exposed concrete

Close to the ocean, salt spray settles on concrete and can draw into the surface. A quality sealer reduces how much moisture and salt penetrate, slows weathering of exposed aggregate and colour, and makes routine cleaning much easier. For coastal homes, sealing is one of the simplest ways to protect your investment.

Mould, lichen and algae

Shady, damp areas on the Bass Coast often grow mould, lichen and algae that make concrete slippery and unsightly. We clean these off with appropriate treatments before sealing, and sealing helps slow regrowth.

Rust and fertiliser stains

Rust spots from bore water, sprinklers, fertiliser or metal objects can be treated with specialised cleaners before sealing, though some deep stains may only fade rather than disappear.

Sealing new concrete

New concrete needs time to cure and dry before sealing, typically a few weeks. If sealing is included in a new job, we return at the right time.

Gloss or natural

Gloss sealers deepen colour and look striking but can be slippery and show scuffs. Matte and satin sealers look more natural and hide wear. We recommend based on the surface and where it is.

Sealing before selling or renting

A freshly cleaned and sealed driveway makes a strong first impression for buyers and holiday guests. We can work to tight timelines before a sale or the holiday season.

Caring for concrete between seals

Sweep regularly, rinse off salt and sand, clean oil and food spills quickly, and avoid harsh acids. When water stops beading on the surface, it is time to plan the next seal.

Sealing holiday rentals

We can schedule sealing between bookings so guests are not disrupted.

Bass Coast ground, weather and council rules

Wonthaggi sits where the coastal dunes of the Bunurong coast meet the clay country rising toward the Strzelecki foothills. Near the beaches at Cape Paterson, Inverloch and Kilcunda the ground is often pale sand that drains fast but moves if it is not confined and compacted. Inland, around North Wonthaggi, Dalyston and the farms, heavy clay swells in a wet winter and cracks open in a dry February. Parts of the old coal-mining town also carry fill, ash and brick rubble from a century of building. Add salt spray, sea mist and strong south-westerly winds, and concrete here needs a properly designed base, the right mix and careful curing. Each job gets a test hole, and the base is designed around the layers it shows.

Driveways, paths and patios within your own boundary usually need no permit. Any new or altered crossover across the nature strip, footpath or kerb needs a vehicle-crossing permit from Bass Coast Shire Council, which covers Wonthaggi, Inverloch, Phillip Island, San Remo and every town we work in. Accesses onto the Bass Highway or other main roads also involve the state road authority. House slabs, larger sheds and some coastal works need a building surveyor and engineering. We spell out whatever applies in your quote.

What a Wonthaggi Concreting quote shows

Our quotes are broken into the parts of the job rather than a single total. You will see the measured area, demolition and tip fees for any old concrete, pavers or gravel, how deep we excavate, the rock base specification and compaction method, slab thickness and reinforcement, the surface finish or pebble blend, the joint plan, drains and stormwater connections, edges and steps, sealing, and the council vehicle-crossing permit where one is needed. If a concrete pump, a long wheelbarrow run, traffic control on the Bass Highway or protection for a neighbour's driveway is required, it is listed on its own line.

This site deliberately carries no square-metre pricing. On the Bass Coast the same size driveway can sit on clean dune sand in Cape Paterson, wet grey clay in North Wonthaggi or old mine fill in South Dudley, and each needs different groundwork. A price published online would be wrong for most readers, so we prefer to look at your block and quote what it actually needs.
