The owner of this house in the town of Kislingbury, Northampton called me in because her sealer wasn’t performing very well and the floor had only been cleaned and sealed 6 months previous by her builders contractor. Although the rest of the floor was in very good condition there were quite a few tiles that were being easily scratched from day to day use and stained from liquid spills which should have been easy to remove.
Cleaning a Limestone Tiled Floor
Even though this work was carried out in January, with outside temperatures of -2 degrees, I insisted that the underfloor heating was turned off to eliminate the potential of it impacting the performance of any products used during the restoration.
I began by stripping off all of the old sealer with the coarse pad from the Tile Doctor burnishing system. I then diluted a solution of the high alkaline cleaner Tile Doctor Pro Clean and this was mainly applied to clean the grout lines because as I previously mentioned, the condition of the tiles was generally speaking very good. The solution was allowed to dwell for approximately ten minutes, before I proceeded to agitate the area with a scrubbing brush to remove ingrained dirt. The floor was then finished off using the rest of the pads in the burnishing pad system to restore the surface shine and then rinsed down with water to remove the slurry.
Sealing a Limestone Tiled Floor
After allowing the floor adequate time to dry, I sealed it with Tile Doctor Colour Grow, an impregnating sealer which provides not only a durable surface seal, but also contains properties which intensify the natural colours in the Limestone.
I completed the seal with the underfloor heating off and this allowed the sealer to cure properly. Just to make sure, I also tested several different areas for water repellency – it was only after that I allowed my client to put the heating back on!
