The recent winter floods had a devastating effect on Cumbria, with many houses suffering severe damage from exposure to the water. This property in Kirkby Lonsdale had been flooded, and while the contract cleaners had made some basic repairs, the Jura Limestone floor had been left dull and patchy, and in dire need of a professional restoration.
Jura Limestone has been in use for over 180 million years and is an absolutely top quality stone, consisting of up to 97% dense calcium carbonate. Thanks to its density it is far less porous than other types of Limestone available on the market. Generally speaking, this makes it easy to look after as it is more difficult for dirt to become ingrained.
Burnishing and Cleaning a Jura Limestone floor
To restore the surface of the floor we used a process known as burnishing, which achieves particularly good results on polished stone tiles. It involves the application of several burnishing pads with different grades of grit to break down any old sealer and dirt, and to gradually smooth and polish the rough surface of the tiles.
In this case, I worked my way through through the four pad system, starting with a Coarse pad lubricated with a little water before moving on to Medium, Fine and Very Fine pads to achieve the desired polished finish.
Following this, we decided that the grout would also benefit from a special clean with Tile Doctor Pro Clean, and so applied the high alkaline cleaner to tackle the outstanding stains and dirt. The whole floor was then rinsed with clean water to remove any remaining slurry and then left to dry.
Sealing a Jura Limestone floor
We returned to the property the following day, by which time the floor had dried completely. I gave the tiles another polish with an Extra Fine burnishing pad, before proceeding to seal the floor with two coats of Tile Doctor Colour Grow. This is an impregnating sealer that soaks into the pores of the stone to provide durable protection whilst enhancing the natural shades in the Limestone.
Finally, I gave the floor one last polish with the Extra Fine burnishing pad just to tighten up the hone and polish off any extra sealer.
You can see the results in the corresponding photographs, and needless to say, the customers were exceptionally pleased to have their fantastic floor back to looking its best, especially considering the significant damage caused by the floods.
