Cleaning and Resealing a Limestone Patio

Details below of a Limestone patio I was asked to clean at a property in the affluent neighbourhood of Alderly Edge, Cheshire, famous for being the home of choice for several Premier League footballers. In fact Alderly Edge, which lies not too far south of Manchester and is one of the most sought after places to live in the UK. My client was unhappy with the look of the patio had previously been sealed using a topical sealer, and this had left the tiles looking dull and lifeless.


Limestone is a fantastic natural stone, popularly used for internal floors as well as patios, it comes in a variety of fantastic colours and shades. What my client really wanted for the patio was a wet look to bring out the character of the Limestone. So, my job was to strip the old sealer off and replace it will one that would achieve the desired finish.

Stripping off the old sealer

To strip the old sealer from the patio, I used a series of fine diamond encrusted burnishing pads which are applied in order from Coarse, Medium, Fine and then Super Fine. The coarse pad is effective at stripping off sealer without damaging the tile, and without the need to use a liquid product. The finer burnishing pads then rebuild the appearance of the Limestone to provide a nice deep shine.

Applying Sealer to a Limestone Patio

The new sealer of choice was Tile Doctor Colour Grow, which can be used on both internal and external natural stone surfaces. Colour Grow is an impregnating sealer which penetrates deep into the pores of the stone, providing both long-lasting resistance and durable protection against ingrained dirt and stains. As you can see from the photos, Colour Grow is also specially formulated to intensify the natural colours in the stone, and it really helped to bring the Limestone back to life again.


The finished job left this patio with the wet, polished look my client had requested. She was very pleased with the result and amazed by just how quickly such a marked difference could be made. Another happy client!
