Protection where it matters.
A surface in service is scrubbed, pressure-washed, walked on, splashed with cleaner, baked under the sun and marked with oil. Every one of those loads acts at the surface. That is where a seal has to hold, and it is exactly where a pore sealer has nothing. Here are the four resistances that decide it, with the honest bounds on each.
Location decides the fight
Wear happens at the surface, not in the pore.
This is the whole argument in one idea. Real use happens in the top fraction of a millimetre. A pore sealer builds its protection in the wrong place for how a surface is actually used, so the cleaning pad, the pressure washer, the sun and the oil all meet effectively bare stone. We build the protection where the use is.
MineralProtect and GlassProtect are the one and only next-generation sol-gel surface protective coatings in Australia. A dense inorganic network, about a ten-thousandth of a millimetre thick, engineered exactly where the use happens. New to the mechanism? Start with how sealing actually works.
The four real-world resistances
Four loads. One place they all land.
Cleaning, chemicals, UV and oil. These are what actually wear a seal out in Perth, and every one of them acts at the surface. Here is how our architecture meets each, and the honest bound on each, because none of them is immunity.
Resistance · 01
Cleaning and abrasion
Real surfaces get scrubbed, pressure-washed and walked on, and all of that happens at the surface. The load-bearing inorganic network sits right there, so it keeps working through the brushes, cream cleanser, hoses and traffic that wear other sealers off. The durability is architectural, network density and crosslink redundancy, not a hardness number.
The honest bound: it is not scratch-proof and not abrasion-proof. It fades slowly and predictably, with no cliff-edge, and renews with a top-up rather than a strip.
Resistance · 02
Chemical resistance
This is a surface built for cleaning, not just for water. The inorganic backbone does not oxidise and break down the way an organic resin does, so it stays stable through the routine alkaline detergents and pool chemistry of real maintenance, the same exposure that quietly hydrolyses a pore sealer and makes it fail from the inside.
The honest bound: more resistant, not immune. No sealer is acid-proof or alkali-proof. Strong acids and alkalis, and long dwell times, attack any silica-based surface. It holds at routine cleaning strength and short contact, not at the extremes.
Resistance · 03
UV stability
Sun is what breaks most sealers down in Perth. Our surface is inorganic, so it carries none of the chemistry that UV attacks in an acrylic, epoxy or polyurethane film. It does not yellow or chalk the way an organic film does, and it holds up under the UV that ages other coatings and cleaves the water-repelling tail off a buried impregnator.
The honest bound: far more UV-resistant, not UV-proof and not permanent. It still weathers, slowly, over years. It eases back toward untreated rather than failing all at once.
Resistance · 04
Oil
Water beads off almost anything. Oil is the one that stains for good: car and barbecue oil on a driveway, sunscreen and body oil around a pool, cooking oil on a benchtop. A standard pore sealer repels water only, so it leaves the surface open to the exact thing that marks it. Here, oil and grease sit on the surface and lift in cleaning instead of soaking in.
The honest bound: oil is an outcome, not a number, and not stain-proof. Marks wipe up rather than set, but a spill left for weeks can still stain, and it does not remove the need to clean.
On glass, that oil resistance is the quiet win: GlassProtect fights the oily soap scum a water-repellent-only surface cannot shed, and it is 3x more durable than uncoated glass, still beading above 100 degrees at 3,000 scrub cycles. More on that in glass protection explained.
The contrast that decides it
Judge a sealer on the layer you actually use.
A penetrating impregnator was engineered to slow water soaking into the bulk, not to survive how a face is cleaned and used. That single design choice sets its whole life story.
Its protection is stranded below the wear zone
A pore sealer builds its repellency one to ten millimetres down the pore, with the water-repelling tail projecting into the pore space. That is the wrong location for real use. The cleaning pad, the pressure washer, the alkaline cleaner, the sun and the oil all meet effectively bare pore-mouth stone.
The layer you feel dies first, and silently
The thin top sub-millimetre of repellency you actually experience is stripped first by abrasion and cleaning, while UV cleaves the tail that does the repelling. The buried chemistry can still be detectable in the stone long after the beading you can see has gone. Present is not the same as effective, and there is no visual cue that it has failed.
A deep reservoir cannot come back up to renew the face
Once the top layer is abraded or sun-aged, the protection buried below cannot wick up to re-protect the surface. We put a dense inorganic network at the surface, where wear, cleaning and staining happen, so it meets all four loads together and renews there with a top-up, on clean stone, no strip.

Proven, not promised
Built to survive the cleaning.
The real test is never the rain. It is the cream cleanser and scrub pad glass gets, and the pressure washing and alkaline cleaners stone gets. That is what wears sealers out, and it is the test our architecture is built for, because the protection sits where the test lands.
- Still beading at 3,000 scrub cycles. Around 3x slower repellency loss than the leading brand, in comparable cream-cleanser abrasion testing. (GlassProtect)
- Stable under alkaline cleaners and pressure washing. The exact conditions that hydrolyse and fail a standard pore sealer, invisibly, then all at once. (MineralProtect)
- Degrades slowly, not suddenly. No hidden failure point, no cliff-edge. It eases back toward untreated over years, and renews with a top-up, not a strip.

The honest answers
The questions we get on durability.
What actually wears a sealer out?
Not the rain. It is the cleaning and the use. Scrubbing, cream cleanser, pressure washing, foot traffic and tyres, alkaline detergents, pool chemistry, UV and oil all act at the surface, in the top fraction of a millimetre. That is where a seal has to survive, and it is exactly where a pore sealer has nothing, because its working protection is buried millimetres down out of reach.
Is it chemical-proof? Can I use any cleaner I like?
It is more resistant, not immune, and we will always say so. The inorganic surface stays stable through routine alkaline detergents and pool chemistry, the exact cleaning that breaks a pore sealer down from inside. But no sealer is acid-proof or alkali-proof. Strong acids, strong alkalis and long dwell times attack any silica-based surface, and acid attacks the stone itself. Use routine cleaners, do not leave harsh chemicals sitting, and it holds up through the cleaning a surface actually gets.
Does the sun break it down like it breaks down other sealers?
Far less. Our surface is inorganic, so it carries none of the chemistry that UV attacks in an organic acrylic, epoxy or polyurethane film. It does not yellow or chalk the way those films do under Perth sun. It is far more UV-resistant, not UV-proof and not permanent. It eases back slowly and predictably over years, and renews with a top-up rather than a strip.
Will it stop oil and stains for good?
Oil is an outcome here, not a promise. Oil and grease sit on the surface and lift in cleaning instead of soaking straight in, so a dropped-oil, sunscreen or barbecue mark wipes up rather than setting. It makes cleaning faster and far less frequent. It is not stain-proof. A spill left for weeks can still mark, and it does not remove the need to clean.
Why does protecting the surface beat a sealer in the pore?
Because a surface in service is used at the surface, not in the pore. A penetrating impregnator builds its repellency one to ten millimetres down the pore, which is the wrong place for how a surface is actually cleaned and used. The thin top layer you experience is stripped first and fastest, and the deep reservoir cannot wick back up to renew an abraded or sun-aged face. We put a dense inorganic network right at the surface, where the cleaning, the chemicals, the UV and the oil all land together.
Does this mean my glass will never spot again?
No, and any coating that promises that is not being straight with you. Hard water always leaves minerals behind when it dries, on any glass. What GlassProtect changes is that the minerals can no longer bond to the glass, so instead of setting hard and etching in, they sit loosely and wipe straight off. You get far less spotting, and the spotting you do get clears with a quick wipe or squeegee, not a razor blade and acid.
