Sealing guide · Perth
Should I seal my new concrete driveway?
Yes, and the smart time to do it is once the slab has cured and before it picks up its first oil drip or tyre mark, because a new driveway is the cleanest it will ever be. Here is the honest version, including the wait you should not skip.
The short answer
Seal it, but seal it at the right moment.
A new concrete driveway is worth sealing, and the best window is after the slab has cured, usually around a month from the pour, and before it starts collecting stains. Bare concrete is porous and thirsty. Left unprotected, it drinks in the first dropped oil, the first leaking car, the barbecue splash and the red-dirt runoff, and those marks set in the pores where scrubbing will not lift them. Sealing while the surface is unmarked is the whole point. You are protecting a clean slab, not trying to rescue a stained one.
There are two honest catches, and we would rather you hear them from us. First, do not rush it. Fresh concrete keeps hardening and releasing moisture for weeks, and sealing too early traps that moisture and stops a proper bond. Second, not every driveway needs the exact same thing, and if your concreter left a film on it the timing changes. Both are easy to sort once we know what you are working with.
The one-line version: a new slab is the cleanest it will ever be, so sealing now beats sealing after the first oil drip and tyre mark. Just let it cure first.
Why timing matters
Why sealing new beats sealing stained.
The value of sealing a driveway is highest on day one and drops with every mark it collects. Here is what a clean start actually buys you.
Stains never get a chance to set
Once oil, rust or grease soaks into bare concrete it is usually in there for good, and sealing over it just locks the mark under the coating. Seal a clean slab and there is nothing driven into the pores to hide. Oil and grease then sit on the surface and lift in cleaning instead of staining, so a spill you get to reasonably soon wipes up.
No stain removal to pay for
On a driveway that has been in use for years, we often have to clean marks back before we can seal, and some never fully come out. A new slab that has been kept reasonably clean preps quickly, which keeps the job simple and means you are protecting the concrete you actually paid for while it still looks new.
You protect the surface, not just the look
A driveway is not just about looks. Perth sun bakes an unprotected slab flat and grey, and reticulation overspray leaves mineral rings. Sealing early keeps the face protected through all of that from the start, rather than after the sun and sprinklers have already had a season at it.
One clean job, on the record
Sealing a new driveway is about as straightforward as this work gets: a sound, clean surface, prepared and sealed once, and registered under a 10-year guarantee. No stripping old failed film, no chasing stains that will not lift. You start protected and stay protected.
The wait you should not skip
Let it cure first.
This is the one part people get wrong in their hurry to protect a new slab. Sealing early feels responsible, but too early works against you.
Give the slab time to cure
Concrete keeps hardening and releasing moisture for weeks after it is poured. The common guide is to give a bare slab around a month before sealing it. Seal it while it is still green and wet and you trap moisture in and get a poor bond. There is no prize for beating the cure, and a slab that has been kept clean is still in great shape at four weeks.
Keep it clean in the meantime
While it cures, treat it gently. Keep cars, oil and hard knocks off it where you can, and rinse away builder dust and reticulation overspray rather than letting it dry on. The cleaner the slab is when we get to it, the better the seal bonds and the less preparation it needs.
If there is a cure-and-seal on it, tell us
Many concreters lay down a cure-and-seal on the day so the slab cures evenly and looks finished. That is an acrylic film, and our coating bonds into the concrete itself, so it is not applied over a fresh film. That does not mean you missed your window. It means the timing is different, and we will look at what is on there and tell you straight when to seal it properly.
What you are actually buying
Not a film on top. A seal in the surface.
Worth knowing what makes this different from the cure-and-seal your slab came with. For decades there were only two ways to seal concrete: lay a film on top, or soak a repellent down into the pores. Both wear out in Perth. Our coating is a third way. It is a water-based mineral sol-gel that bonds into the surface as a thin, colourless, breathable network, right where the driveway is used.
Because it bonds in rather than sitting on top, there is no film to chalk, peel or lift under hot tyres, and it stays breathable so the slab can keep releasing moisture. That is the short version. For the full plain-English mechanism, read how surface sealing actually works.
What your driveway needs
Not every new driveway is the same job.
The answer is still yes, seal it, but the finish you have changes the detail. Find yours and read the guide made for it.
Plain or broom-finish
The most common new driveway in Perth, and the sweet spot for this coating. Colourless protection that keeps plain grey looking plain grey. Read the guide →
Exposed aggregate
Washed or seeded pebble finishes have more surface and texture to protect, and show marks readily. Sealing new keeps the stone tops clean and the paste between them shielded. Read the guide →
Coloured or oxide
Charcoal and oxide colour-through slabs are worth protecting early, because sun and wear on the face are exactly what dulls the colour you paid extra for. Read the guide →

Where we tell you straight
What sealing a new driveway will not do.
Sealing new is genuinely worth it, but a good sealer is honest about the edges of the job.
It will not fill or stop cracks
Concrete moves and cracks along control joints and shrinkage lines as it settles. That is structural, and a thin surface coating does not glue a slab together or bridge a moving crack. It protects a sound surface from staining, oil and wear. If a new slab is failing structurally, we will say so rather than seal over it.
It is not permanent or stain-proof
It is a long-lasting treatment, not a forever fix, and we never call it stain-proof. It makes a real difference to how oil and marks behave, and the beading you can see fades before the protection does, so a surface that has stopped beading is a prompt to check it, not proof it has failed. It lasts years and tops up without stripping.
Sealing new does not mean sealing forever untouched
A sealed driveway still gets a rinse and the occasional clean, and it is due a top-up eventually, over itself, with no strip back to bare concrete. Sealing early gives you the best possible start, not a driveway you never think about again.
New driveways, answered
The questions we actually get.
How long should I wait before sealing a new concrete driveway?
Let the slab cure first. Concrete keeps hardening and releasing moisture for weeks after it is poured, and the common guide is to give it around a month before you seal a bare surface. Sealing a fresh, still-wet slab traps that moisture and does not bond properly. There is no rush to beat the cure, because a new slab that has been kept reasonably clean is still in great shape at four weeks. If your concreter left a cure-and-seal film on it, the timing is different again, so tell us what is on there and we will look at it before we book anything.
My concreter already sealed the driveway. Do I still need to seal it?
Most likely yes, but not straight away, and it is not a criticism of your concreter. On the day a good concreter lays down a cure-and-seal so the slab cures evenly and looks finished on handover. That is an acrylic film sitting on top, and in Perth sun and traffic it is doing well to last a year or two before it chalks, whitens or lifts under hot tyres. Our coating is a different thing entirely. It bonds into the concrete surface itself rather than sitting on top, so it is not applied over a fresh film. When that first seal is spent, that is the moment to protect the concrete properly.
Is it better to seal now or wait until the driveway stains?
Seal it while it is clean. A new slab is the cleanest it will ever be, with no oil driven into the pores and no tyre marks worked in. Once a stain has soaked into bare concrete it is usually in there for good, and sealing over it just locks the mark in. Sealing early means you are protecting an unmarked surface, not trying to rescue a stained one. Waiting until the first oil drip is the expensive way to find out sealing was worth it.
Will sealing a new driveway change the colour or make it slippery?
No colour change. MineralProtect is colourless and non-pigmenting, so plain grey stays plain grey and a coloured slab keeps its tone. It does not add a wet-look gloss. It changes how water and oil behave on the face, not the finish. On slip, our coating is a thin layer that follows the broom texture rather than laying a film over it, so it works on the surface energy, not the profile your foot keys into. We do not hold a slip rating or make slip claims, and we will do a test patch you can wet and feel before we seal the rest.
What does it cost to seal a new concrete driveway in Perth?
Sealing is $16 per square metre all-in, with a $950 minimum, and you get a confirmed price before you book. That covers preparation, the coating and registration under the 10-year guarantee. A clean new slab often preps quickly, because there are no stains or old failed film to clean back first.
