The scorching hot summer has meant we are all in the garden and making much more use of our outside spaces. Our client got in touch because her Indian Sandstone patio was looking a little unloved. Looking forward to entertaining outside it was time to bring it back up to scratch so it wouldn’t be an embarrassment.

This house in Northampton which is the county town of Northamptonshire, lying on the River Nene it is one of the largest towns in the UK, had a lovely large patio. The Sandstone paving was looking tired and dirty, it was covered in lichen, embedded soil and was missing grout. I discussed with the client how Tile Doctor could help, and she agreed to go ahead so I returned a few days later. Indian Sandstone is a very hardwearing material, but one of the biggest problems we find with stone flooring outside is it soon becomes stained by the elements, especially with our great British weather, sun, (acid) rain, and ice. Without its’ protective sealer porous stone quickly becomes ingrained with dirt making it increasingly difficult to clean effectively.

Cleaning and Restoring Indian Sandstone Patio in Northampton

I pre-treated the entire are with a medium dilution Tile Doctor Pro-Clean and left it to dwell for about 15 minutes, so it started breaking down the soil. This is a highly concentrated multi-purpose high-alkaline cleaner which is great on heavily soiled areas, breaking down the dirt and the lichen. This was then scrubbed in using a rotary machine and stiff buffing brush.

This was followed by pressure washing and rinsing the entire area with water, removing the soiled waste with a wet vacuum. It is always a little easier carrying out this type of messy job as we are outside. This process took much of the day to complete and got the Indian Sandstone tiles really clean. They were already looking good and had changed from a dull grey colour to a lovely warm beige.

Grouting and Sealing Indian Sandstone Patio Northampton

I allowed a few days for the area to dry and then returned to finish renovating the patio, thankfully the weather remained dry! My first task was to re-grout areas where the grout had become loose, this made an instant difference defining the tiles as they should be, also this will prevent the problem with weeds growing between the paving slabs.

Finally, I applied Tile Doctor Colour Grow Sealant to enhance the natural colours of the stone. Colour Grow is an impregnating sealer that soaks into the pores of the stone protecting it from within. It is also a breathable sealer which is ideal for external areas where moisture is an issue.

As you can see from the pictures this process made a huge impact and the colours appear much brighter, the customer was delighted with the results and she is looking forward to being able to enjoy her garden. The hot weather is thankfully continuing so she will be able to enjoy the space for many weeks to come.
