After a period of time Kandla Grey paving can discolour, showing yellow to orange staining on the surface which is difficult to remove.

My Kandla Grey patio has discoloured, can it be restored?

We know the feeling when you suddenly notice rust stains on your once beautiful and shining patio. If you are looking for the answer on how to remove rust from your paving and what cleaning products to choose, Stoneworld have you covered. 

We have developed a wide range of products that will dissolve rust and get rid of stubborn stains from your concrete surfaces leaving your patio looking as newly bought. In this blog post, we will discuss why staining on Kandla Grey pavings can develop over a period of time as well as present the solution to remove rust with the right products.

Kandla Grey sandstone paving is currently very popular due to its contemporary grey tones. Presently, grey is a frequently chosen theme in all areas of home design.

After a period of time, Kandla Grey paving can discolour, showing yellow to orange staining on the surface which is difficult to remove. These stains are caused by iron deposits which occur naturally within the stone and over time these deposits leach. They can become present on the surface, potentially ruining the overall appearance of the stone landscaping area where they are present.

The process of leaching is accelerated by our often damp climate. Although this process is a natural occurrence, it is undesirable to most people, who select Kandla Grey for its pale grey colour.

Another reason why rust stains appear could be abandoned furniture that was left outside in the rain. This can result in discolouration of paving if a metal is left in contact with concrete during rainy days. 

What can be done about the discolouration of my Kandla Grey patio?

Firstly, we advise you to reduce the problem by buying your Kandla Grey sandstone paving from a reputable stone merchant. At Stoneworld we specify a particular seam in our favoured quarry in India for the selection of our Kandla Grey Sandstone paving. This ensures that we have a product that has less iron deposits embedded within it from the outset.

More iron deposits occur in cheaper grey sandstone

If you buy a lower cost product, it is possible that you will be purchasing material that has a higher density of iron deposit embedded in it, possibly causing future issues. This will not be visible at the point of purchase, but the discolouration will occur at a faster rate than with a better quality sandstone.

Nevertheless, discoloration may occur in any Kandla Grey sandstone to some degree.
