Cleaning and Grouting Sandstone Patio Paving in Kettering

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.

Power Cleaning a Patio in Achurch

These photographs were from earlier in the year at a residence in Achurch which had a number of paved areas and patios which like any patio in the UK had discoloured over winter and the colours in the stone had become grey and un-inviting. Being a Tile Doctor and Carpet Cleaner requires an investment in high pressure cleaning equipment which lends itself well to external patio cleaning.

Patio Pressure Washing

With less preparation required when working outside to protect other surfaces I was soon setup and started by applying a strong dilution of Tile Doctor Pro-Clean which is a multi-purpose cleaner and stripper which being an alkaline rather than acidic product is safe to use on stone, tile and grout. The solution was left to soak into slabs for a while so it could get to work the grime and it was then scrubbed in using a yard brush. The next step was to use a high pressure washer running at a medium pressure so as not to blow out the mortar between the slabs. The pressures available on the truck mounted pressure washer are much higher than those available on domestic machines so you do have to be careful.

The job took half a day and I think you will agree the patio now looks newly laid.
