We were contacted by a business owner in Mawdesley near Ormskirk who had recently had a large Granite Patio installed. Unfortunately, the installer had left the patio covered in cement grouting stains and residue and as you can imagine he was not happy about it.
This is something we often get asked to resolve and you may here it referred to as Hazing or Smearing. The solution depends on the surface material and can normally be removed using an acidic cleaner such as Tile Doctor Grout Clean-up or Acid Gel. However, in this case the surface of the stone looked really dull and marked with lines and what appeared to be boot marks. I decided the best solution would be to use a set of diamond pads to grind off the top layer of stone to reveal a new surface and then to polish it.
Resurfacing a Large Granite Patio in Mawdesley
To resurface the Granite, I used a weighted buffing machine and a set of coarse stone resurfacing pads. The extra weight was needed to ensure a good contact with the stone and the process commenced with a very coarse 100 grit pad to remove the damage using only water for lubrication.
The pad was run each Granite slab around three times generating a lot of residues in the process. A wet vacuum was used to remove the residue and with it being such a large patio it took some time before that was completed and we could move onto the next pad.
Once done the process was repeated with a 200-grit to renovate the surface after using the coarse pad. Again, only water was used and the whole area was rinsed and extracted to remove the residue. This action removed all the damaged surface material and was followed by the application of a very fine 3000-grit burnishing pad to give the patio a nice sheen.
Sealing a Large Granite Patio in Mawdesley
Fortunately, I had picked a good window in which to do the work (thanks to the BBC and Carol Kirkwood) and the weather remained dry. This was important as I was able to return the next day and prepare the Granite for sealing.
First, I applied a product called Tile Doctor Stone Oil to the Granite, this seeps into the pores of the stone giving it a rich dark colour improving the overall appearance and integrity. This was then locked in with an application of sealer which for this patio I used Tile Doctor Colour Grow. There are a few reasons I chose this product including the fact that its breathable which is important when dealing with external stone and it contains a colour enhancer which brings out the natural colours in the Granite.

My client was very impressed with the transformation and relieved we had managed to put the life back in what was a very expensive patio. I’m please to say we subsequently asked to work on two more patios and different stone floors at the same property.
