#light-limestone

Ashprington is a small, picturesque village just outside of Totnes and boasts a quaint stream running through the centre of the village, several listed cottages and a pub, ‘The Watermans Arms’, which offers good food - including their now famous triple-fried chips! I was approached by the owners of one of the beautiful listed cottages in the village, which had the river running through the garden and was a stone’s throw from the pub, because they had extensively developed the building around five years ago. This work included the installation of a lovely light-limestone floor spanning the kitchen and open-plan extension, however the floor was starting to lose its natural appeal and the owners were finding it harder to clean. With summer fast approaching the owners were keen to get the property ready for their annual holiday and a visit was quickly arranged. I took a closer look at the floor and conducted a test on a small area to give the clients an idea of what to expect. The limestone was honed smooth but was not polished and the customers were keen not to add too much of an unnatural shine to the floor. The grout lines in some of the more heavily used areas, such as by the sink, were also discoloured and would require a decent scrub with an appropriate Tile Doctor product.

I spoke to the clients about options for the finish to be applied after cleaning and they decided that they wanted to keep the tiles as light as possible with a slight shine. With the clients impressed with the test area I prepared I went away and produced a detailed quote which was sent to them along with our general T&Cs and the work was booked in to be completed shortly after.

Cleaning a Light-Limestone Tiled Kitchen Floor

The floor spanned quite a large area, some 40m2, and had some larger items of furniture that needed to be moved before starting. Because the house was empty at the time it was a straightforward task to divide the area into two and stagger the work over four days so that the furniture could be moved to suit. The first task was to scrub the grout with a specialist grout brush, designed to get right into the grout lines and work the product in. Limestone is an acid-sensitive stone so a strong alkaline cleaner called Remove & Go was used which was then allowed to dwell for around 45 minutes to work its magic. The area was quickly rinsed before using a series of diamond impregnated burnishing pads attached to a rotary scrubbing machine, ranging from a coarse 400 grit (200 in some of the more stubborn areas) up to a fine 1500 grit to clean the stone. The whole area was then rinsed using a truck-mounted system that feeds pressurised water to the floor whilst extracting the dirty water at the same time. A rotary spinner tool was also used which helps to get a really thorough rinse. The first area was then left to dry overnight, aided by the underfloor heating which was installed with the tiles.

Polishing a Light-Limestone Tiled Kitchen Floor

The following day a very fine 3000 grit diamond pad was used to ‘spray burnish’ the floor which uses very little water and ensures that any remaining residues are lifted as well as finishing the floor in the highest level of mechanical polishing possible prior to sealing. If the clients desired a higher level of shine a powdered high shine sealer would have been worked into the tiles to achieve a highly reflective surface, however the mechanical polish was the highest level of shine wanted.
