I was asked by a building company to look at some slate flooring that was laid during a refurbishment to the offices of a German television station based in central London.
The architect was not happy because there appeared to be some grout haze and some grout along the ridges that you get in slate. I carried out a demonstration to the building manager and she was pleased with the result and we were awarded the job.
Because of the nature of the business I had to do the job out of hours, which suited me because there were 4 toilet areas to do over 6 floors and I was able to get on with the job without any interruption.
Slate Tile Cleaning
On my arrival I laid a coating of Tile Doctor Remove and Go mixed 50/50 with NanoTech Ultra-Clean to 2 toilets and left it to dwell while I brought all my equipment in and set up. These two products together create a very powerful stripper cleaning solution ideal for the job in hand. I left the products to soak into the tiled slate floor of the first toilet for an hour before scrubbing it in using water and a hand scrubbing brush. The soiled solution was then removed using a wet vacuum and then rinsed and sprayed with Tile Doctor Grout Clean-Up to remove any remaining grout haze off the surface of the tile. The slate was the given two mores rinses with clean water before being left to dry.
Before starting on the next floor I left a mixture of Remove and Go and NanoTech Ultra-Clean to dwell on the next floor. I then carried on with this process described above until all the floors were cleaned.
Slate Tile Sealing
Once the floors were dry I put a single coat of Tile Doctor Colour Grow sealer down on each floor which is a sealer which really brings out the natural colour of the stone.
The client had requested a shiny final finish so the sealing was completed using two coats of Tile Doctor Seal and Go on each floor.
When I had finished the site manager said that he couldn’t believe how nice they had come out and was looking forward to the reaction of the clients.
