How to keep liquid limestone driveway polished and clean in Perth


Greg Harris, Negosentro | When one thinks of driveways, pathways, patios or decks, and what it takes to either repave, or repair them, the first thing that springs to mind is the cost of traditional concrete paving and brick laying. However, there is a viable and attractive alternative to this paving tradition and many use it already – Liquid Limestone!

So what is it?

Firstly, liquid limestone is more affordable than mainstream concrete drabness and adds a more attractive look to your outdoor area. Similar to its cousin, liquid limestone however, is made up of a mixture of limestone, additives and concrete. Although its strength is not regulated like normal concrete, contractors will be able to advise on the best mixes. It can be poured like regular concrete into any shape you need, and because of the method its laid, will give you the natural appearance you seek whilst keeping its strength and preventing cracking.

But remember, limestone is porous and if left unprotected can expose you to all manner of downfalls which will undo all the wonderful results you are looking for. So, make sure that you apply a water-based sealant to prevent stains and nasty little algae and bacteria critters from gaining power on your newly laid realm!


Once laid and protected with sealant, maintaining your freshly paved limestone creation is actually easy. It’s important to note here that liquid limestone is highly prone to developing mould, especially when installed in shady areas or close to the pool where it’s next to water. That’s why it’s important to pressure wash your liquid limestone surface at least every two weeks to keep it looking as exquisite as it did when you first installed it.

Also, due to the fact that liquid limestone is porous, it’s best to give it a high pressure wash in order to remove any unwelcome guests which may try to burrow into your foundations. And yes, it’s the microscopic invaders you need be most concerned about from the outset. Spores, bacteria and algea all have a go at intruding on your space, so defend your keep with a mixture of water and chlorine.

Armed with a brush, scrub surfaces regularly to maintain that freshly polished look, and make sure to get into crevices that mold and mildew could form. When washing and scrubbing doesn’t work, some people turn to chemical or rubbing alcohol, which can damage your hair, your clothes, the environment, and can potentially give you a headache as well.

However, be careful to not be too aggressive with your pressure washing either, and pre-treat the limestone with a patio cleaner before you actually clean in order to protect it from further damage.

Then, apply the solution onto the limestone with the pressure washer before sealing it with a sealer in order to protect the stone from the elements. Applying a sealer will also reduce the stone’s required maintenance, although you’ll still have to hose it down twice a year with a patio cleaner and leave it on the surface to get rid of any algae that may have formed.

Whatever you do, be sure to use a chemical-free sealer, and apply two coats of it onto the limestone at any one time, leaving a few minutes in between coats. If the sealer hasn’t fully penetrated through the stone and there is still a white residue on top of the stone 45 minutes after application, you can wipe it clean with a roller sponge so that you get that nice polished finish.  

Lastly, always remember to wear safety gloves, boots and goggles when cleaning your liquid limestone surface to protect yourself in case some of the product is accidentally sprayed towards your face.  

Where can I get it?

Limestone, like rock and salt and water, is abundant everywhere, but obtaining it in the form that you want is what really matters. Reputable artisans such as those found at www.repave.com.au will resolve all your paving needs at a fraction of the cost of traditional paving.

So, pour it on “limestone and all” as they say!
