To complicate things further the Carpet had been stuck down with a strong adhesive and a local builder had advised them to remove the glue using brick acid. Although this was successful it had the side effect of discolouring the grout lines and no amount of rinsing with the floor with water to dilute and wash off the acid would resolve the problem.
Happy for me to resolve the problem, my client informed me they were going on holiday and would like me to do the work whilst they were away. This was a great idea as it would guard against unwanted foot traffic during the cleaning and sealing process and it would also mean they would have a nice surprise waiting for them on their return.
Deep Cleaning a Terracotta Tiled Kitchen Floor
After protecting the Kitchen units and skirting boards with plastic sheeting my first job was to strip any remaining sealer off the Terracotta tiles using a strong dilution of Tile Doctor Pro-Clean. The solution was spread across the floor and then left to dwell for twenty minutes before scrubbing it in with a black scrubbing pad attached to a rotary floor buffer. I then used a wet vacuum to remove the now dirty cleaning solution from the floor.The grout was also given a good scrub using more Tile Doctor Pro-Clean but this time it was scrubbed in with a narrow stiff brush until I was satisfied it was as clean as it could be. The floor given a good rinse and I then inspected the floor tile and grout to ensure it was clean and free of sealers, any areas that needed ore work were retreated and the floor given a final rinse and dry with the wet vacuum before being left to dry off fully overnight.
Sealing a Terracotta Tiled Kitchen Floor
I returned the next morning and tested the tiles with a damp meter to ensure they were dry before beginning applying the sealer. All was well, so I started by applying a single coat of Tile Doctor Colour Grow. Colour Grow is an impregnating sealer that seeps into the pores of the tile protecting it from within and enhancing the natural red colour of the Terracotta in the process.Once the first coat had dried I followed up with two coats of Tile Doctor Seal and Go which is a compatible water-based sealer that works really well on clay tiles and adds a lovely sheen finish to the floor.
The last step was to resolve the problem with the discoloured grout lines by applying a white grout colourant to the grout. This gave the grout a fresh and consistent appearance throughout and also has the benefit of sealing the grout which will protect it from staining and also make it much easier to clean.
Last step was to finish the sealing of the floor by topping up the sealer with another three coats of Seal and Go to ensure the floor was fully sealed.
The result was a huge improvement and now looked like a recently installed Terracotta floor. When my customer returned from holiday they were more than happy with the floor and the work I had done.
