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.
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.
