Large Grout Restoration Project at Manchester HQ

Posted on by

We recently received a request from the Manchester headquarters of a global engineering and construction company which was founded in 1911 and now operates in over 160 countries. The company contacted us because they were keen to restore the tiled walls and floors in 20 different toilets and kitchens throughout the offices.

It would be a big job, but we were more than happy to respond to the enquiry. We agreed a complimentary visit to the office for us to test clean one of the floors to show what kind of results could be achieved. The management team at the offices was very impressed with the results of the test clean and asked us to complete the whole job.

There was talk of replacing some of the grout completely and I explained that it would be less expensive and time consuming to restore the discoloured grout through cleaning and recolouring and they were happy to let us proceed on that basis.

Cleaning Discoloured Grout Lines

As there were 20 different rooms to clean and recolour, our team worked in a couple of rooms at a time to ensure firstly, that we got the job done in time and secondly, that we wouldn’t disturb the normal operations of the offices.

The process was as follows. To clean the grout, we used a strong mix of Tile Doctor Pro Clean, a strong Alkaline-based cleaner which reliably gets the job done in situations where most run-of-the-mill cleaners won’t. We applied the Pro Clean to the grout lines and tiles and left it to dwell for about 10 minutes. We then scrubbed the grout lines with specially designed grout brushes and followed by cleaning the tiles with a black scrubbing pad fitted to our rotary machine.

After scrubbing the tiles and grout, we rinsed and removed all the dirty water and cleaning
solution with a wet vacuum. We repeated the rinsing process several times to make sure all chemicals were neutralised. Similar cleaning techniques were used to clean the tiles on the walls, but the walls took a lot longer to complete as the tiles were much smaller and therefore had a greater number of grout lines. When all the cleaning process was finished, we left the tiles to dry until the next day.

Recolouring the Wall and Floor Grout Lines

To recolour the grout lines, we used the Grout Colourant from Tile Doctor’s own range. Available in ten different colours, this is a brilliant product as it rejuvenates and also seals the grout. The fact that the colourant is epoxy based will also make future maintenance easier, as you can just wipe off the dirt.

For the floor grout lines, we used the Natural Grey colourant and for walls we used White. The application of the colourant is simple yet quite laborious when working in large rooms. After finishing, we wiped off any excess product.

Overall, it took us two weeks to complete all the work but I think you will agree from the photographs that all toilets and kitchens look completely rejuvenated. We got lots of good feedback from the people who work at the company. They all stated that the toilets and kitchen look like new and even asked us about restoring grout in their own homes.

Edwardian Hotel Marble Floor Restoration

Posted on by

Windlestraw is a picturesque Edwardian manor hotel overlooking the Tweed Valley, near Walkerburn in the Scottish Borders area of Scotland. One of the bathrooms in the manor was in the process of being refurbished when two layers of floor tiles were removed, unveiling an original Marble tiled floor dating back to the 1920s.

After the top layers of tile had been removed the Marble was still covered in old adhesive and cement and although Marble is known for its quality and durability the hotel owner didn’t want the building contractor to proceed any further in case they damaged it. The owner was keen to restore the Marble floor as an original feature so we were called in to set the situation right.

Refurbishing a Marble Tiled Bathroom Floor

To restore the floor I used two processes known as milling and burnishing. Milling literally involves grinding down uneven or rough surfaces using very coarse, diamond encrusted pads. The pads are usually used to resolve lippage issues on natural stone but in this case we needed to use the very coarse abrasive pads to grind off the adhesive and cement. I used a set of three coarse milling pads rinsing with water between each pad and starting with a 50 grit pad, before moving on to 100 and 200 grit pads. This process was very effective and ground off the cement and adhesive, while also removing any lippage in the tiles to leave a completely flat surface.

Milling leaves the surface of the Marble tiles clean but in a rough condition and this is where the second process Burnishing comes in. Similar to milling, burnishing focuses on achieving a polished finish with the application of ever finer grades of polishing pads and is often used to bring back the polish on Limestone and Travertine as well as Marble. Moving on to the burnishing, I worked my way through the four diamond encrusted pad system lubricating with a little water and again rinsing between each pad to remove the slurry. The grits go from Coarse (400 grit), Medium (800 grit), Fine (1500 grit) and then eventually Very Fine (3000 grit) and come in a 17” pad for use on a rotary floor machine and were applied twice in sequence to achieve a fantastic polished shine.

Sealing a Marble Tiled Bathroom Floor

The floor was given a final rinse and then dried with a wet-vacuum before we proceeded to seal the floor using Tile Doctor Shine Powder which is a crystallizing powder that is applied directly to the floor and worked in using a buffing pad fitted to a rotary machine.

Shine Powder provides a very high shine (as you can see from the photos), along with a tough durable finish. On top of this, it is suitable for sealing all natural stone, including, of course, Marble, along with Limestone, Granite, Slate and Travertine.

The customer was absolutely delighted with the results as were we although it’s now up to them to ensure the bathroom fitters take appropriate care when completing the room which I’m sure will look absolutely fantastic when complete and no doubt add to the allure of this magnificent hotel in the Scottish Borders.

Limestone Floor Cleaning at a Hotel in London

Posted on by

Details below of a Limestone floor installed in the reception of a Victorian hotel in London’s West end. The Limestone Floor had been cleaned incorrectly leaving very noticeable staining marks to the grout lines. We were asked to return the floor to its natural appearance and improve the finish from Matt to Polished.

Cleaning the Limestone Floor

Working at night to minimise disruption for the hotel guests our first step was to clean the floor and grout with a dilution of Tile Doctor Pro-Clean. Pro-Clean is ideal for this purpose due to its alkaline formula, acidic products even those with mild acidity will damage the floor over time and can lead to small holes forming where the calcareous stone has been dissolved.

The next step was to burnish the floor using four stage diamond encrusted twister pad system. This is a labour intensive process where you scrub the floor using a buffing machines fitted with different pads; each pad is designed for a different purpose and will remove sealers, grind off ingrained dirt, smooth the surface as well as polish.

Polishing and Sealing the Limestone Floor

To obtain the requested highly polished finish the floor was then polished using Tile Doctor Shine crystallising powder which as well as providing a high shine also leaves a tough durable finish, ideal for high traffic areas such as this. We finished off the floor with a single coat of Tile Doctor Colour Grow impregnating sealer which was then buffed to a high shine finish.

For regular cleaning we have advised the hotels maintenance team to use a 1-30 dilution of Neutral Cleaner applied with a microfibre flat mop, water rinsed and the dried with second clean microfibre mop.
