At the start of the year we usually get asked to restore the appearance of patios and other outside areas which have suffered from the staining of autumn leaves and the ravages of winter cold snaps. Most patios are quite straight forward to maintain however when you’re dealing natural stone then it’s best to call in your local Tile Doctor to ensure nothing is applied to the stone that could damage it.
Such was the case with this four-year-old Sandstone Patio at a house in the town of Kettering. Unfortunately, it was not sealed when it was first installed and the combination of weather and UV sunlight had faded the tiles, this together with general soiling had greatly affected the appearance of this beautiful stone and could almost have been mistaken for concrete slabs.
Maintaining Sandstone Patio Paving
My first course of action was to lightly spray the area with a dilution of Tile Doctor Pro-Clean which is a powerful tile cleaning product that is safe to use on Stone. The solution was allowed to soak in for a while before being agitated with a brush to bring out the dirt. This was followed by pressure washing with a spinning tool at a medium pressure so as to not damage the stone.
Once dry I re-grouted the entire area and then sealed with Tile Doctor Colour Grow Sealant which is a impregnating breathable product (essential for damp environments) that also enhances the natural colours of the stone.
Within hours of finishing the customer came home and called me straight away to say he couldn’t believe the transformation that was achieved and they looked better than when they were first laid.

Lichen, moss and other plant-based staining is a common sight on patios exposed to the UK climate. For many property owners, it’s a very difficult task to keep patios looking great in the face of the natural effects of the environment. However always happy to help Tile Doctor is available to provide the professional cleaning and sealing needed on a regular basis.
This Sandstone tiled patio in Rushden was certainly a prime candidate for restoration. Not only was it completely covered in lichen and moss, but it was also cracked in parts and missing grout. The patio would therefore need not only cleaning and sealing, but also re-grouting.
Cleaning a Stained and Damaged Sandstone Patio
To begin the restoration, I opted to power jet wash the entire area to remove as much of the initial layers of moss. Then, I mixed a strong dilution of Tile Doctor Pro Clean, which is a powerful and reliable alkaline cleaner suitable for use on both internal and external natural stone tiles. This was applied liberally to the patio and scrubbed into the stone to cut through the particularly stubborn stains. The two photos below show the fantastic result.
Re-grouting and Sealing a Sandstone Patio
After completing the cleaning phase, I allowed the patio to dry completely overnight before returning to re-grout the entire area with mortar. To finish off I applied a fresh sealer in the form of Tile Doctor Seal and Go Extra, which an acrylic-based, fully breathable sealer appropriate for outside use.
The below pictures show the final result. As you can see, it was a complete transformation – and my very happy customer will agree! With the right products and methods, it’s possible to bring new life back to weathered patios.
