The owner of this residence near Caerphilly Castle had discovered a 150x150mm red Quarry tiled floor in the kitchen which dated back to before 1900 and had unfortunately been tiled over by a previous owner. Keen on restoring such an original feature the owner set about removing the tiles on top using a chisel and scraping off the adhesive, it was at this point we got the call to assist.
Restoring a Quarry Tiled Floor
Before proceeding my first job is to always check the moisture levels, many of these old floors have no damp proof membrane so without taking a base reading it’s tricky to know if the floor has thoroughly dried later. The kitchen was being replaced and the old kitchen had been removed so I was able to work on the restoration before the new one had been installed making the task easier.
To clean the floor I realised I would need a strong cleaning solution to get these old Quarry tiles clean so I diluted Tile Doctor Pro-Clean 50:50 with Heavy Build-up Remover or Tile Doctor NanoTech HBU as we like to call it. This was applied to a wet floor and scrubbed in using a scrubbing machine fitted with a coarse back pad running on slow speed. I rinsed the floor every so often so I could see the difference and discovered my choice of cleaning product has proved to be effective and fast. Before long I was happy to rinse away the now soiled cleaning solution satisfied that I could not improve the tiles any further with more cleaning.
Sealing a Quarry Tiled Floor
I left the floor to dry for 24h hours before returning to seal the tiles. On my return I checked the moisture levels and there were some high readings so using a heat gun I applied some gentle heat to the tiles allowing them to cool before checking again. This did the trick and the second reading was much better so I proceeded to seal the tiles using Tile Doctor Seal and Go which I find works well on quarry tiles. The quarry tiles were quite worn and very porous and as result needed at nine coats of sealer before they were fully sealed. I do find multiple of coats of sealer works well on floors of this condition as it helped to hide the imperfections and marks caused by the chisel and scrapper.
The owners were delighted with the results and asked me to come back and restore their terrazzo hallway floor which will be subject to another post.
