Liquid Limestone Cleaning Perth

It Isn't the Same as Natural Limestone

Liquid limestone is concrete. It's poured on site, with limestone aggregate through the mix and a fine finish on top.
Natural limestone is quarried stone. Blocks and slabs, cut from the ground.
They look similar and they behave nothing alike.
Liquid limestone is a hard surface and cleans as one. Natural limestone is soft and must be soft washed.

Why Liquid Limestone Goes Black

Mould and algae grow in it like any concrete. It goes black mostly, and green in places — worst around pools, under trees and on shaded sides. Being a pale surface, it shows every bit of it.

How I Clean It

Pressure cleaned, kept moving — this is a surface where careless technique leaves permanent lines
A detail lance into the control joints, edges and up against coping
Enough dwell time on the growth that it lets go properly
Rinsed thoroughly so nothing dries back in

Where It Turns Up

Driveways
Pool surrounds and coping
Patios and alfresco areas
Paths and courtyards

Sealing — This Is How You Can Protect Your Surfaces and Keep Them Looking Better for Longer

Cleaning takes off the growth and dirt. Sealing is what protects the surface and slows it coming back.

An unsealed surface drinks water in. It holds that moisture down in the pores and stays damp after the top looks dry — and that damp is exactly what the mould and algae feed on. Sealing fills the pores, so less water goes in and the surface dries out faster. The black takes longer to come back and doesn't get as bad when it does, and spills sit on top instead of soaking in, so you have a real chance at preventing severe stains.

It is not a magic coating that keeps the surface perfectly clean. It still needs washing — it just needs it less often, and it's easier to clean in the future.

I seal the same day I clean. It is an additional service that complements the cleaning.

Being Straight About It

The white top layer is thin. Aggressive cleaning wears it through and exposes the stone underneath, which doesn't go back. That's why technique matters more here than on plain concrete.
Bore water staining is chemical and sits in the surface rather than on it. I do treat it, and how far it comes back varies with how long it has been there and how heavy it is. Worth asking about rather than assuming nothing can be done.
Cracks and control joint damage stay.

Questions and Answers

Is liquid limestone the same as limestone?

No. Liquid limestone is poured concrete with limestone aggregate in it. Natural limestone is quarried stone. They need different methods, and treating one like the other is how surfaces get wrecked.

Should it be resealed after cleaning?

It's worth considering on this surface more than most — it's pale and porous, so it shows growth early. Sealing slows that and makes the next clean easier. It's a separate job from the cleaning and priced separately.

Will it come up white again?

If the top layer is still intact, yes. Where it's already worn through, that part will always read differently — and it's better to know that going in.
