Remove Natural Oxidation from Granite Paving

Granite Paving is one of our best-sellers for driveways and patios and, as a natrural stone, can be subject to natural variations such as oxidation. However, with the right cleaning products and a little patience, this is simple to remove. So you can continue to enjoy your new space without any unwanted markings!

What Is Natural Oxidation in Granite Paving?

Oxidation in stone paving occurs due to the porosity of the stone and the minerals contained within. Some types of natural stone paving, such as Granite, contain iron, or iron ore, which can be drawn to the surface when subjected to moisture. This can cause the stone to appear to change colour in some places, appearing as orange or brown marks.

Oxidation stains can also occur when water runs over metal fixtures or fittings and trickles down to your paving, depositing iron particles from oxidation (rusting) into your paving.

Rust stains are common on driveways due to being deposited by vehicles, but can also be present in patios and pathways that are home to garden furniture, as well as barbecues, chimeneas, fire pits, and similar garden furniture.

What most people don’t know is that weed killer can also cause rust stains!

Many weed killers and similar products contain ferric sulphate which can cause rust stains when it encounters the iron-rich compounds in the paving’s aggregate. These types of stains will appear as blotches rather than defined lines, which often means they’re fainter and difficult to spot.

Preventing Rust Stains in Future

Once you’ve removed oxidation or rust stains from your Granite, you need to keep them away. Here’s how:

Seal Your Paving
We recommend that you seal any natural stone paving in order to prevent the stone from taking on excess moisture. Most sealants will form a protective layer across the surface of your paving, whilst still allowing the stone to ‘breathe’.

Store your Garden Furniture
One of the best ways to prevent hard-wearing rust stains is to store garden furniture, barbecues and similar items away from your paving during adverse weather, which will prevent oxidised particles from reaching your stone. Move furniture into the shed or onto the grass.

Keep an Eye Out
You need to keep an eye on your Granite Paving to see if rust or any other types of stains appear and as soon as they do, you should apply a rust stain remover or heavy-duty Granite cleaner to ensure the stain does not penetrate the stone too far.
