This Quarry Tiled floor was in a house in the village of Clifton-upon-Dunsmore which is close to Rugby; the tiles had been covered in an unattractive damp proof tar membrane and then hidden under carpet for many years and the owner wanted the floor restoring.
Quarry Tile Tar Removal
To remove the tar membrane the Quarry Tiled floor was coated with Tile Doctor Remove and Go mixed 50/50 with NanoTech Ultra-Clean and left to dwell for 30 minutes to an hour. We then scrubbed the floor using a rotary machine fitted with a black scrubbing pad, the combined effect of the chemicals and scrubbing action broke down the tar and loosened it from the surface of the tile and was then removed with water and a wet Vacuum. It took a whole day to complete the floor as it was necessary to remove the tar in 2 metre square sections.
The last step was to use a warm air dryer to speed dry the floor before it was sealed. For this we used two coats of Tile Doctor Colour Grow which is a breathable sealer that will provide durable stain protection as well as allowing vapour transmission a necessary feature for old floors with no damp proof course.
