Removing Stains from a Dull Green Limestone Tiled Kitchen Floor in Pickmere

We were contacted by a resident of the west Cheshire village of Pickmere about their 90m2 Green Limestone tiled kitchen floor which has been stained by washing up liquid. Although washing up liquid appears to be a harmless the product clearly contains some ingredients that upset the sealer and polish.

Unfortunately patching up the floor up wasn’t really an option as the result would be equally patchy. The only option was to re-polish the tiles with a set of Tile Doctor burnishing pads and apply a fresh sealer. I worked out a quote which was agreed and a date set.

Burnishing and Cleaning a Limestone Tiled Floor

Before working on the Limestone, I set about cleaning the grout lines with a strong dilution of Tile Doctor Pro-Clean which is a strong Tile and Grout cleaner. The pads can struggle to reach into the grout lines so I find the best way to clean grout is by hand with stiff brush and extract the soiling with a wet vacuum.

Next step was to start cleaning the stone using the first of the burnishing pads. This first pad is a coarse 400-grit which cuts through and removes old sealers, scratches and dirt from the stone. The pad is attached to a weighted buffer machine and run over each tile using only water for lubrication. The water turns into a dark liquid which was rinsed with more water and removed using the wet vacuum.

This process was repeated with 800-grit pad and the floor was then inspected. Unfortunately, it showed several areas where the staining remained so I spot treated them using Tile Doctor Reduxa. This is a liquid that is sprayed on the stain and then warmed up with a heat gun which literally steams the stain out of the stone. This process has to be repeated several times for the stain to disappear

With the staining gone I finished off burnishing the Limestone with the remaining two pads which are a fine 1500-grit and then the extra fine 3500-grit which is applied using only a little water sprayed onto the stone. This last pad builds up a high-quality polish on the stone and really bring up the finish.

Sealing a Limestone Tiled Floor

The floor was left to dry off fully overnight and I returned the next day to seal the Limestone first checking with a damp meter that the stone was dry. To get the finish the customer wanted a coat of Tile Doctor Colour Grow was applied with is an impregnating colour enhancing sealer. Impregnating sealers works under the surface by occupying the pores in the stone thus preventing dirt from becoming ingrained there. Any excess sealer was wiped off the tile before treating the stone to a gentle buff with a White pad to bring up the shine even further.

Once complete the staining was gone and the floor looked amazing much to the relief of the owner. For aftercare I recommended the use of Tile Doctor Stone Soap which is a pH neutral cleaner for the maintenance of polished floor that contains a patina enhancer.
