How to Protect Your Limestone From Mould, Mildew and Grime Build-Up

Summer is a wonderful time to invite your friends and family around for a BBQ or just simply relax in the backyard, but the last thing you want to be looking at is grimy, discoloured limestone pavers or walls.



Shield your limestone from dirt and deterioration


Limestone is a great choice as either pavers or walls, it’s a native material to Perth and is naturally cool to walk on in summer. Unfortunately, as it is such a porous stone it tends to absorb dirt and hold water. We’ve all seen discoloured and darkened limestone buildings around Perth.


In most cases, you won’t see the dark colouring and stained limestone for a few years, but as soon as your limestone is set in place it starts to absorb the loose materials around it, like sand, dirt and worst of all, water. 


Very often water is the root cause of limestone damage. Water easily picks up anything around it like oils, chemicals, acids and other corrosive materials. Once this pools on the limestone it can be absorbed and start to eat away at the stone. All this means is that you need to take a few steps to protect your limestone and keep it looking amazing. 


Limestone Sealing


The first step you should take to protect your limestone is to have it periodically sealed to prevent any dirt getting into the stone, causing it to stain. Limestone sealing will give your stonework a protective coating to keep any dirt or water from penetrating the stone, causing it to deteriorate. DJL Services’ limestone sealing process uses special treatments made in Perth specifically for limestone. We offer a combination of oil and water-based sealers to suit your needs.


Due to the natural deterioration of the limestone sealer, we recommend scheduling limestone sealing every 1-2 years. The protective coating on the limestone will also help prevent any chipping or cracks that may occur.



Limestone Cleaning 


Cleaning limestone is more about what not to do than what to do. Limestone reacts easily to most cleaning products, especially acids, and you may end up doing more damage to the stone than good. Water can also be dangerous for limestone as any leftover water could be absorbed into the stone, leading to mould and mildew.


The easiest and safest option for limestone cleaning is to hire professional high-pressure cleaners. At DJL Services, we use only boiling water at a high pressure to remove stains and dirt from your limestone. Meaning that not only is it not harmful to your limestone, but it is completely safe for your kids, pets and garden.


Limestone is a great asset to any home or business, but make sure you're taking care of your limestone, so you can get the maximum appeal during the summer season. A few easy maintenance tasks every few years is all it takes to keep your limestone pavers and walls looking amazing. And remember, if you are looking for residential, commercial or industrial cleaning companies that specialise in high pressure cleaning in Perth, contact DJL Services for a free quote to transform your property and get you Summer ready!
