Terracotta Tiled Utility Room Floor Deep Cleaned and Sealed in Richmond

These are terracotta tiles installed 28 years ago in the utility room of a property in Richmond KT2. A new owner moved into the property a year ago and were going to pull the tiles up to replace with vinyl. They assumed the tiles were too far gone for restoration but decided to give me a call first to see if there was anything that could be done.

I visited the property and conducted some tests and established that we could in fact work with the tiles. They were dark with dirt, but I was confident they would come up really well and provided the owners with a quote to deep clean the tiles and then re-seal to protect them.

Deep Cleaning a Terracotta Tiled Utility Floor

The work began by deep cleaning the tiles and removing what was left of the original sealer. It was clear from the start that multiple coats of a protective coating of some kind had been applied and as this broke down with use, dirt had become deeply ingrained into this sealer and not the tile. Deep cleaning of the tiles could only commence once this coating was gone so I started by mopping Tile Doctor Remove and Go stripper diluted with water onto the floor and leaving it to soak in for fifteen minutes. The solution was then agitated with a brush and and the process repeated several times.

It was a small area, so a DeWalt handheld rotary machine fitted with an 80-grit carbide brush was then used to scrub the floor in an attempt to take the sealer off. I soon realised that due to the numerous coats that had been applied the process would need repeating several times. Each application and scrub improving the state of the tiles gradually giving me confidence that I was in fact on the right path.

Once the sealer had been removed, I decided to use Tile Doctor Heavy Build-Up Remover to help with the cleaning process. This was applied to the Terracotta and Grout and then left to soak in for twenty minutes before scrubbing the floor with the Dewalt machine fitted with the carbide brush. The resultant slurry was vacuumed away with a Hyundai wet vacuum. The work was done this way in small sections to ensure the Terracotta was as clean as possible.

Once I was satisfied, the tile and grout was cleaned to its best possible condition the floor was given an acid rinse using Tile Doctor Grout Clean-up. The acid in this product does several things including dissolving any salts that may be in the tiles, further cleaning up the tiles and neutralising the PH level of the floor following the use of alkaline cleaners. After being brushed into the tiles and left for five minutes the solution was removed with the wet vacuum and the floor mopped lightly with clean water.

Terracotta is made of clay, which is very porous, so I decided it was best to leave the floor over the weekend to dry out. This allows for any water vapour to completely evaporate before sealing and allowed time for any remaining salt issues to appear so they could be dealt with before sealing.

On my return, I sealed the floor using Tile Doctor Seal and Go Extra and a paint pad, it took four applications of the sealer before I achieved the correct level and resulted in a fully sealed surface.

The result was a completely transformed floor; the dark and dirty red colour had gone and was replaced with a fresh orange Terracotta. My client was delighted with the result and left the following feedback:

Daniels standard of work is outstanding. Our tiles came out better than we ever imagined. He arrived on time and was very professional and explained the complete process. He was also very tidy. I would not hesitate to use him again and would thoroughly recommend him.

Before leaving I took time to explain the importance of using Tile Doctor Neutral Tile Cleaner to maintain the floor going forward. This is a mild but effective Tile and Grout cleaner that won’t impact the sealer.

Renovating a 27-year-old Terracotta Tiled Kitchen Floor in Brentford

This job is a terracotta tiled kitchen floor at a property in Brentford that was laid 27 years ago and then sealed using wax. Since then, it hasn’t been properly maintained the entire time they have been down and was looking dark and permanently dirty.

Sometimes I can quote for renovating a floor from photos, however, in this case I made sure to book a survey as I could see that the tiles were heavily soiled, as you would expect from 27 years of use with no cleaning. On inspection of the tiles, I could see there was a lot of stripping that needed to happen to remove what was left of the wax.

I explained to the clients the process and the limitations and discovered their expectations for the floor. What the client was looking for was for the tiles to be as clean as possible with a good gloss on the top for easier mopping and maintenance. Once I had this information, I worked out a price and booked the work in.

Once everything was protected, I carried out a damp proof reading on the tiles, noted it down and then applied Tile Doctor Remove and Go stripper to the top of the tiles. I mopped this around for 5 minutes and then agitated with a brush. Once happy it was taking effect, I used coarse carbide brush to scrub the solution in and remove the old sealer. Once complete and the resultant soiling rinsed away and extracted, I was able to inspect the floor and confirm the sealer had been removed.

Happy with stage 1, work progressed to the next step which involved covering the entire floor in a thick layer of Tile Doctor Acid Gel and allowed it to sit for 15 minutes. I did this to prevent too much penetration from the water during the next cleaning phase, but clay tiles like Terracotta react very well to acid during cleaning aiding the whole process. The next step was to use the rotary machine fitted with a black pad and give the tiles a good deep clean. I worked methodically ensuring not to flood the entire floor and again working in sections to allow me to vacuum off the surface water to avoid too much penetration into the tile.

Once happy with this I took a wire brush and cleaned the grout, although it had already mostly been cleaned by the carbide brush on the handheld it allows me to get down and close to the floor so that I can easily spot areas that may have been missed. I then said my goodbyes to the client and went away for 2 days, leaving a fan behind that they moved around to different sections of the floor each day until dry.

I stayed in contact with the client leading up to the sealing day and we determined the floor was ready to go. On arrival I took a damp meter reading and after comparing it to the one I took earlier was happy with the result.

Sealing the floor began with the application of Tile Doctor Seal and Go Extra and a paint pad. Four coats of sealer were applied. This is a fully breathable modern acrylic sealer that performs well on Terracotta improving its appearance and adding long lasting protection.

The following day the client called to say that the floor looked a bit dull in places, so I immediately booked them in for the bank holiday Monday and made my way back. On arrival I could see that not all areas of the floor had taken the sealer as well as I thought so I proceeded to apply another 6 coats. Terracotta is a very porous clay-based material and so this is not unusual.

The floor looked even better after this so I’m glad they requested a call back, visiting Terracotta floors more than once can happen, the most important thing is getting the correct results in the end with the least amount of disruption possible.
