These Sandstone flagstones were in the hallway of a house in the 16th century village of Stretton under Fosse, Warwickshire. The flagstone floor was in good condition however it had never been sealed so every time it was cleaned the cleaning product soaked into the floor and was less effective also the customer wanted to reveal the natural colours in the Sandstone and needed some of the grout repairing.
Cleaning Sandstone Flagstones
The first job was to clean and flush the flagstone so we set about cleaning the stone using Tile Doctor Pro-Clean mixed 50/50 with NanoTech Ultra-Clean and further diluted with water. I often use this combination, Pro-Clean is a strong and effective alkaline cleaner whilst NantoTech adds tiny abrasive particles that assist and speed up the cleaning process.
The solution was applied using a mop and then worked into the floor using a rotary buffing machine fitted with a black 17” scrubbing pad. The soiled cleaning solution was then picked up off the floor using a wet and dry vacuum and the floor was given a thorough wash down with clean water to remove a trace of cleaning products that may impact the sealer. There were a few areas of grout that had cracked and become lose so we set about replacing the grout with a closer match as possible and then left for the day to allow the floor to try overnight.
Sealing the Flagstone Floor
We sealed the Sandstone flagstones with a single coat of Tile Doctor Colour Grow, there are a number of sealers we could of used for this floor all have different effects and differing levels of stain protection against spills but Colour Grow is really durable and helps to bring out the deep colour from within the stone . To finish and build up the lustre and richness of the colour we then applied seven coats of Seal & Go which add a nice low sheen to the surface of the tile.
