Premium Clear Sealing for Long-Lasting Concrete Protection

Clear penetrative sealing is a protective treatment that soaks into the pores of your concrete rather than sitting on top as a film. Unlike topical sealers that create a visible coating, penetrative sealers work beneath the surface to form a chemical barrier against moisture, salts, and contaminants. The result is concrete that looks completely natural -no sheen, no colour change -but is significantly more resistant to water absorption, efflorescence (white salt deposits), mould growth, and general weathering. It’s the ideal choice for homeowners who love the look of their existing concrete and simply want to protect it from South East Queensland’s harsh UV, rain, and humidity without altering its appearance.

A professionally applied clear penetrative sealer will typically last between 5 and 10 years depending on the level of foot and vehicle traffic, direct sun exposure, and how well the surface is maintained. Driveways and high-traffic areas tend to sit closer to the 5-year mark, while covered patios and pool surrounds can easily push beyond 7 years. The great thing about penetrative sealers is that reapplication is straightforward -because there’s no film to strip or sand back, you simply clean the surface and apply a fresh coat when it’s time. We always recommend a light pressure wash once or twice a year to keep your sealed concrete performing at its best.

The key difference comes down to where the sealer sits. A penetrative sealer absorbs into the concrete and chemically reacts within the pores to create an invisible, breathable barrier. It won’t change the look or texture of your concrete at all. A topical sealer, on the other hand, forms a physical film on the surface -this can add a gloss or satin sheen, enhance colour, and provide a slightly more robust barrier against surface-level stains. Topical sealers are great when you want to enhance or change the look of your concrete (like our tinted sealer or gloss sealer options), while penetrative sealers are the go-to when you want pure protection without any visual change. Both have their place, and we’re happy to walk you through which one suits your property best during a free on-site assessment.

Yes, absolutely. The penetrative sealers we use are low-VOC and water-based, making them safe for indoor applications including garages, laundries, rumpus rooms, and polished concrete living areas. Once cured, the sealer is completely odourless and non-toxic. During application there’s a mild chemical smell, but it dissipates within a few hours -especially with good ventilation. We regularly seal indoor concrete floors for homeowners across Brisbane, the Gold Coast, and the Sunshine Coast, and it’s a particularly popular choice for garages where you want protection against oil drips, tyre marks, and moisture without changing the look of the floor.

Clear sealing significantly reduces staining by preventing liquids from absorbing into the concrete’s pores. Oil drips from cars, leaf tannin stains, rust marks, and general grime will sit on the surface rather than soaking in, making them much easier to clean up with a hose or pressure washer. That said, no sealer makes concrete completely stain-proof -if a spill is left sitting for an extended period, some discolouration can still occur. The key benefit is that sealed concrete gives you a much bigger window to clean up spills before they become permanent, and regular maintenance becomes far less intensive. Most of our customers tell us their sealed driveways look cleaner for longer with significantly less effort.

Our process starts with a thorough surface preparation -this typically involves a high-pressure clean and, depending on the condition of your concrete, an acid wash or chlorine treatment to remove any existing mould, algae, or built-up grime. We let the surface dry completely before applying the penetrative sealer using professional low-pressure spray equipment, which ensures an even, consistent coat across every square metre. For most residential jobs, we apply two coats to ensure full penetration and maximum protection. The entire process usually takes one day for an average-sized driveway or patio. You’ll need to keep foot traffic off the surface for around 4 hours and vehicles off for 24 hours to allow the sealer to fully cure.

Absolutely. Clear penetrative sealers work brilliantly on all concrete finishes including plain concrete, exposed aggregate, stamped concrete, stencilled concrete, and even brick paving. In fact, exposed aggregate is one of the most popular surfaces we seal -the penetrative sealer protects the stones and cement matrix without dulling or glossing over the natural texture and colour variation that makes exposed aggregate so attractive. For stamped and stencilled concrete, sealing helps preserve the pattern definition and prevents the grout lines and recesses from collecting dirt and mould. Whatever your concrete finish, we’ll assess it on-site and recommend the best product and approach for your specific surface.

Pricing depends on a few factors -the total area in square metres, the current condition of the concrete, how much preparation work is needed, and your location within South East Queensland. As a rough guide, most residential clear sealing jobs (driveways, patios, pool areas) fall somewhere between $15 and $30 per square metre including preparation and two coats of sealer. Larger areas typically come in at the lower end of that range. We provide obligation-free quotes after an on-site inspection so you know exactly what’s involved and what it’ll cost -no hidden fees or surprises.

There are a few simple things you can do to help us get started quickly on the day. If we’re sealing your driveway, make sure all cars are moved out of the garage and off the driveway. Give the edges a quick whippersnip or edge so we can seal right up to the borders without grass getting in the way. Push back any rocks, mulch, or garden beds that are sitting on top of the concrete. Move any outdoor furniture, pot plants, or bins off the areas being sealed. And make sure we have access to a power point and a water tap -we need both for our cleaning and spraying equipment. That’s it! We handle all the heavy preparation work from there.

No -this is one of the biggest advantages of penetrative sealers over topical options. Because a penetrative sealer absorbs into the concrete rather than forming a film on top, it doesn’t change the surface texture at all. Your concrete retains its original grip and slip resistance, which makes it an excellent choice for pool surrounds, pathways, and any areas that get wet regularly. Topical sealers (especially high-gloss options) can become slippery when wet unless an anti-slip additive is mixed in, but with a penetrative sealer you don’t need to worry about that. It’s one of the main reasons we recommend clear penetrative sealing for families with young kids or anyone concerned about safety around wet areas.
