Sealing coloured concrete · Perth
Coloured concrete, sealed without changing the colour.
MineralProtect is the one and only next-generation sol-gel surface coating in Australia, and coloured concrete is exactly what it is built for. Your slab is cement-bound, so the coating bonds into it at the surface, stays completely colourless, and holds up to the tyres, oil, cleaning and sun that wear ordinary seals off. The charcoal, terracotta or oxide colour you chose stays the colour you chose. This is our sweet spot.
What actually goes wrong
You paid for the colour. The seal ruins it.
The whole point of coloured concrete is the colour, whether it is oxide mixed through the slab, a dry-shake hardener broadcast on top, or a charcoal driveway that sets off the house. So it stings that the thing meant to protect it is usually the thing that wrecks how it looks. The concreter finishes it with a cheap acrylic colour seal at the payment gate, and within a Perth summer or two that film starts working against you.
The film that came on it
Blushes, chalks, peels
An acrylic colour seal sits on top of the concrete. Under UV and moisture it turns milky and chalky, and hot tyres pull it up on the wheel tracks. The colour then looks patchy and faded where the film has worn, dark and glossy where it hasn't. And a failed film has to be stripped before it can be redone.
The white haze
Efflorescence on charcoal
Coloured concrete shows a white calcium bloom far more than grey does, and against a charcoal or deep oxide it looks like a stain. It rises out of the slab with moisture. Seal it under a film and that haze is trapped underneath, clouding and bubbling the coating from below.
Oil, tyres and grime
Marks that soak straight in
Bare coloured concrete is porous, so a car-oil drip, a barbecue splash on the patio or general driveway grime keys straight into the pigmented paste and sets as a dark shadow. And the darker the colour, the more a worn, greyed, unevenly cleaned surface shows.
How it protects coloured concrete
It bonds into the concrete, not onto it.
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. MineralProtect is a third way, and on coloured concrete it is at its strongest, because the concrete's own chemistry lets the coating bond straight into the surface.
Concrete gives it something to grip
Concrete is bound by cement paste and packed with quartz sand and aggregate, and both carry reactive silicon groups at the surface. Our sol-gel condenses onto them, forming a genuine bond into the concrete as it cures. This isn't a film stuck on top that hot tyres can lift, and it isn't a repellent hiding down a pore. It bonds in at the face, where the driveway is actually driven on.
Protection where the use is
Everything that marks coloured concrete happens at the surface: the tyres that scuff it, the oil that lands on it, the pressure washer you clean it with, the sun that bakes it all day. A sealer buried in the pore protects a place the tyres and the scrubbing never reach. Ours sits exactly where the wear does, as a dense mineral network only tens of nanometres thick.
Colourless, and it still breathes
The layer is thin and follows the surface, so it changes only the surface energy, not the colour, finish or feel of your concrete. The oxide stays exactly as poured. And because it doesn't cap the pores, the slab keeps releasing moisture instead of trapping it, so the efflorescence that whitens and bubbles under a film can complete on top, where it cleans off. Same colour to look at. It just no longer lets water and oil grip.
The edge a pore sealer can't have
Built for how a driveway is actually used.
A coloured driveway or patio is not a lab sample. It gets driven on, pressure washed, splashed with oil and cleaner, and baked in the sun, and every one of those loads lands at the surface. That is precisely where our coating lives, and precisely where a pore-filling sealer has already given up.
Cleaning & abrasion
Survives the tyres and the wash
A driveway gets turning tyres and the pressure washer; a patio gets scrubbed and swept. That is the wear that strips ordinary seals off and lifts films on the wheel tracks. Our surface network is dense and hard-wearing, so it keeps working through the traffic and the cleaning, fades slowly and predictably, and renews with a top up rather than a strip.
Chemical
Designed for cleaning, not just water
The bonded inorganic surface stays stable through the routine alkaline cleaners and degreasers a driveway and patio actually see, the same exposure that breaks a pore sealer down from inside the concrete. It is more resistant, not immune: it is built for everyday cleaning, not for neat acid or degreaser left to sit.
UV
Doesn't yellow and muddy the colour
Sun is what breaks most outdoor seals down, and on a coloured slab a yellowing film muddies the colour you chose. Our coating is inorganic, so it has no organic chain for UV to attack, and it will not yellow or chalk the way an acrylic colour seal does baking in the Perth sun. Far more UV resistant, though not UV proof, and not permanent.
Oil
The mark a driveway actually gets
This is the big one for a driveway. Oil and grease sit on the surface and lift in cleaning instead of soaking in, so a car-oil drip or a barbecue splash on the patio wipes up instead of setting into a dark shadow on the colour. The seals that repelled oil best were fluoropolymer, now being regulated out. We deliver it PFAS-free by design, not by reformulation.
The seal, working
Drag it, and watch.
Same coloured driveway, dry and wet. Water beads and sheets off the sealed surface instead of soaking in. The colour doesn't change, only how the surface behaves. That is the coating doing its job, at the surface, where you can see it.
- Colourless, non-pigmenting. Same colour, same finish, same feel. Only the surface energy changes.
- One price, all in. Cleaned, sealed and registered at $16/m², minimum job $950. Confirmed before you book.
- On the record. Every seal is registered under a 10-year guarantee, backed by certified application.
Where the line sits
What it won't do.
Coloured concrete is one of our best fits, which is exactly why we can be blunt about the limits. Naming them is how you know the rest is real.
- It won't give you a wet-look gloss. Ours is colourless by design, so it keeps your concrete the exact colour it is now. If what you actually want is a glossy, darkened wet look, that is a film-based product with its own tradeoffs, and we will point you to it honestly rather than pretend ours does both.
- It doesn't stop efflorescence at the source. That white bloom is calcium carried out from within the slab, so no surface coating stops it forming. What ours does is stay breathable, so unlike a film it doesn't trap the bloom underneath. It completes on top, where cleaning lifts it.
- No sealer is stain proof. Ours slows how fast oil and liquids soak in and buys you time to wipe. Leave a spill long enough and it can still mark. Anyone who says stain proof is overselling you.
- The beading fades before the protection does. When water stops beading it usually means the surface is due for a re-test, not that the coating is gone. It is a prompt to look at it, not proof it failed.
- It is long lasting, not permanent. The coating degrades slowly and predictably and renews with a top up. It makes cleaning faster and far less frequent. It does not remove the need to clean.
The real questions
Coloured concrete, answered.
Will sealing change the colour of my coloured concrete?
No. MineralProtect is colourless and non-pigmenting. Same colour, same finish, same feel. The only change is that water and oil no longer grip. One thing to be clear on: because it is colourless, it does not add the wet-look gloss a topical colour seal gives. If you want your concrete to stay exactly the colour it is now, that is exactly what ours does. If you specifically want a high-gloss sheen, that is a different, film-based product with its own tradeoffs, and we will tell you so.
Why did my coloured concrete go patchy and white?
Two things, usually together. The first is the acrylic colour seal it was finished with. That film sits on top, and under Perth sun and hot tyres it blushes milky, chalks and lifts, so the colour looks patchy and faded where it has worn and glossy where it hasn't. The second is efflorescence, a white calcium haze that rises out of the slab and shows starkly against a charcoal or oxide colour. A film traps that haze underneath it. A breathable surface lets it complete on top, where it can be cleaned off.
Does it stop the white efflorescence haze?
Not at the source, and we won't pretend otherwise. Efflorescence is calcium carried out of the slab by moisture from within the concrete, so no surface coating stops it being produced. What ours does is stay breathable, so it doesn't trap that bloom beneath a film the way an acrylic seal does. The haze completes on the surface, where routine cleaning lifts it, instead of clouding and bubbling under a sealed skin. A new slab can still bloom while it cures out over its first months.
Can you seal a coloured driveway that already has a sealer on it?
We assess it first. If the existing seal is sound, we prepare the surface and bond over it. If it is a failing acrylic film that is blushing or peeling, that film has to come off before any coating can bond to sound concrete, and we'll tell you that straight rather than seal over a problem. We confirm what your slab needs at the quote.
Does it stop oil drips and tyre marks?
No sealer is stain proof, and we won't tell you otherwise. What ours does is lower the surface energy of the concrete so car oil, barbecue grease and general grime sit on the surface instead of soaking into the pigmented paste. Wipe or wash a drip reasonably soon and it lifts in normal cleaning rather than setting into a dark shadow. On bare coloured concrete that same drip keys straight into the surface.
How long does the seal last?
Two things, kept separate on purpose. The coating performs for years, fading slowly and predictably rather than off a cliff, and it renews with a top up rather than a strip. The guarantee is a 10-year registered guarantee on the repellency function, and it sits on top of your rights under Australian Consumer Law. It is a long lasting treatment, not a permanent one.
