The photographs on this page are of a natural Rough Slate tiled floor installed in the ground floor and stairs of the Touch Business Centre in Stirling where recent building renovation works had left the floor covered in dirt and plaster dust which they couldn’t remove. The owner of the business centre now needed the floor renovating prior to renting out the units to new tenants.
Dating from around 1750 the business units had been converted within the stable block of a large house; now a listed building they would originally have been used for horses and carriages before becoming a milking parlour, estate workshops and garages. The conversion was supported by Historic Scotland and had to retain the feel and features of an historic building and the slate floor was an important part of this.
Cleaning Slate Floor Tile and Grout
To remove the dirt and plaster we used a dilution of Tile Doctor Remove and Go which is a strong coatings remover that’s safe to use on natural stone but also very effective. It was mopped onto the tile and left for around twenty minutes to allow it to soak into the pores of the tile and get to work and break down and soften any remaining sealer and plaster etc. This was then scrubbed into the tiles using a black pad fitted to a rotary machine running on a slow speed; the resultant soiled cleaning solution was then extracted using a wet vacuum, the floor rinsed and the process repeated until we were satisfied the floor was completely clean.
Sealing Slate Floor Tiles
After allowing the floor sufficient time to dry we returned on-site to seal the slate tile and protect it from stains etc checking first with a damp meter that the tiles were indeed dry. To seal the floor we used five coats of Tile Doctor Seal and Go which is a water based sealer (no smell) which adds a nice sheen to the tile and gave the desired finish.

The photographs below are from the Lyle Kirk Church of Scotland in Greenock where we asked to clean the Quarry tiles in the main entrance of the church. As you can imagine the floor is very busy and is constantly in use from parishioners and had now become very unappealing from ingrained dirt and was proving impossible to clean effectively.
Cleaning Old Quarry Tiles
With such an old floor we had to take a lot of care and so using a buffer machine to speed up the process was out of the question. As a result so we cleaned the whole tiled floor including the grout by hand using various strength dilutions of Tile Doctor Remove and Go and then Pro-Clean to remove the years of wax and coatings from the tiles, both products I should mention are safe to use on tile, stone and grout. It was arduous and slow work taking us four days to complete and the floor was given a thorough wash down once clean to remove any trace of cleaning product before sealing.
Dealing with Efflorescence
Whilst cleaning the floor we noticed some signs of efflorescence which is where salts from the ground below evaporate up through the pores in the tile and leave white deposits on the surface of the tile above. The efflorescence was removed easily using Tile Doctor Grout Clean-Up but it alerted us to the fact that normally old floors were traditionally laid directly on compacted earth with no damp proof course and that damp could be an issue that could affect the sealer.

We left the floor to dry off and when we returned being cognizant of the damp issue we chose Tile Doctor Seal and Go Extra to seal the floor, this a new sealing product which is highly breathable and ideal for sealing external tiles or internal tiles where there is a damp problem. Four coats were sufficient and once done the floor looked completely transformed.

This Terrazzo Floor was at the entrance to a School in Kilmacolm where as you can see from the photograph below had come under some heavy use and was now proving difficult to keep clean. We were asked to give it a deep clean, polish and re-seal therefore making it much easier to maintain going forward.
Cleaning a Slate Floor
Hard stone surfaces such as Terrazzo have to be burnished to get the shine back and this process basically involves cutting back the surface with a set of diamond encrusted burnishing pads.
Before burnishing however the floor was swept out to remove any loose debris that could get caught under the pads and scratch the floor. Once that was done a Coarse 400 grit burnishing pad was fitted to our heavy rotary machine and run over the surface with a little water to help lubricate the process, the coarse pad removes surface dirt and coatings such as sealers. Once that was finished we moved onto the medium 800 grit pad which is the first step of the polishing process and also removed ingrained dirt. The surface of the Terrazzo is still quite rough at this stage so once complete with the medium pad the fine (1,500 grit) is used smooth down the surface and continue to build up the polish in the floor. The last pad is a very fine (3,000 grit pad) and this pad builds on the existing polished effect to create a high shine finish.
All these pads are applied with water and the resultant slurry needs to be cleaned off during the process with the final step of giving the floor a thorough rinse with clean water, I can recommend a wet vacuum at this point as it makes light work of removing liquids from floors.
Sealing a Terrazzo Floor
Once the floor was completely dry it was sealed using two coats of Tile Doctor Colour Grow which is a great product to use of these characteristic floors as it brings out the colour in the floor as well as providing on-going stain protection. The floor was then buffed using a white buffing pad to bring up the shine further; needless to say our client was extremely happy with the finished result.
