How to remove rust staining from Kandla Grey Paving

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

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

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.  Over time these deposits are leached from within the stone and become present on the surface, potentially ruining the overall appearance of the stone landscaping area where they are present.

The process of leaching is helped by our (usually) damp climate, and although this process is a totally natural occurrence, it is undesirable to most people, who will have selected Kandla Grey for its pale grey colour.

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.  Here you will find that rather than select he cheapest material available from the quarries in India, care will have been taken to select a better quality stone. For instance, 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.  If you buy a cheaper product, it is possible that you will be purchasing material that we have rejected, and it will therefore have higher density of iron deposit embedded in it storing a problem for you later.  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 purchase.

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

There is a product that can be used to remedy this situation, and the results are impressive.
