Terrazzo Hallway Floor Renovation in Cardiff for the Archbishop of Wales

After undertaking restoration work for Catholic churches in the areas of Wales and England over the past years, I was recommended to the team who maintain the personal residence of the Archbishop of Wales in Cardiff. They had decided to restore the Terrazzo flooring at the property and I was invited over to quote for doing the work.

The flooring had seen many years of wear and tear due to the nature of the building and the amount of footfall relating to meetings and staff. They were delighted to have found us and I was more than happy to get involved and be able to reassure them that I was confident the floor could indeed be restored to its former glory.

I attended a meeting at the property with the church architect to discuss the work needed and talk about the history of the property. It turns out the floor had been covered in carpet and this had been giving people at the property an allergic reaction due to dust accumulating in its thick pile. After removal of the carpet, they discovered the original Terrazzo floor underneath and decided it would be best to have that renovated.

The Terrazzo suffered from numerous issues including adhesive staining and the imprinted pattern of the carpet underlay, fortunately however there were no cracks which can be an issue with Terrazzo floors of this age. Having surveyed the floor I explained the method of work needed to the architect, and we then agreed the price and arranged to carry out the work on a time schedule that suited.

Cleaning and Repairing a Terrazzo Tiled Hallway Floor

To start the restoration process, I began by scraping as much of the remaining adhesive and other contaminates off the surface of the floor with a handheld scraper attached with a 6-inch razor blade. Then I was able to run over the Terrazzo with a coarse 50-Grit diamond pad fitted to a rotary floor machine, this was followed by a 100-grit then 200-Grit pad to remove more ingrained residues. Water is used to lubricate this process and the slurry generated is rinsed off after the application of each pad and extracted with a wet vacuum.

The next stage was to polish the Terrazzo using a set of less aggressive burnishing pads, starting with a Tile Doctor 400-grit pad then a 800, 1500 pad again using water to lubricate the process, rinsing with water between pads and vacuuming the waste as I worked.

The Terrazzo was left to dry out overnight and the following morning the floor was tested for moisture with a damp meter. I do this to avoid applying sealer to a damp floor which can lead to an uneven finish. In this case the readings were fine so I was able to move on to apply the sealer.

The sealer used was Tile Doctor Colour Grow which contains a colour enhancing ingredient that lifts the colours in the stone whilst providing a durable hard wearing sealed finish. Additionally, this product is fully breathable which is an important consideration when sealing old floors like this that won’t have a damp proof membrane.

Once completed the entrance hall looked a lot more welcoming for visitors, more importantly the Archbishop and the Architect were delighted with the result as they were initially unsure if it could be restored.

For aftercare cleaning going forward I recommended the use of Tile Doctor Neutral Tile Cleaner which is a mild but effective pH neutral cleaner that is safe to use on sealed floors and has a nice fresh smell.

Terrazzo Hallway Floor Renovation Barry South Wales

The customer from Barry in South Wales contacted Tiled Doctor to see if anything could be done to revive their Terrazzo hallway floor which was in need of renovation. I contacted them and arranged a mutual time for me to pop over a survey the floor.

Terrazzo is notoriously vulnerable to movement in the subfloor as it’s made from thousands of pieces of crushed stone including marble and laid as single slab so its not just as simple as replacing a tile should any cracks form. I’m pleased to say there was no evidence of any cracks, just signs of wear and tear due to the age of the floor and general maintenance issues.

The customer was about to put their house on the market and the Estate Agent had advised them it would be best if they were to sort the floor out first. Naturally first impression count and the hallway would be the first thing any prospective purchases would see when entering the house. Ideally once deep cleaned and polished the Terrazzo floor would add some wow factor to the property and help turn those prospective purchases into buyers.

Deep Cleaning a Terrazzo Tiled Hallway Floor

To renovate the Terrazzo, no chemical products would be needed for the cleaning, just a set of diamond encrusted burnishing pads starting with a coarse 400-grit pad. The pads fit to a rotary floor buffing machine which is weighted to improve contact with the floor. The coarse pad breaks out the deepest stains, removing dirt and old sealers and each pad is passed over each tile four times. Water is used to lubricate the process and it isn’t long before this turns into a dark slurry. After each pad the floor is rinsed with a little more water and the slurry extracted with a wet vacuum.

This process was repeated with the 800 and 1500-grit pads again rinsing and extracting in-between. After a final rinse the last pad in the sequence which is a 3000-grit pad is applied dry with only a little water sprayed onto to the floor. This last pad is a polishing pad that adds a subtle satin shine to the Terrazzo.

Due to the fact the cleaning process involved minimal amounts of water and the last pad is applied dry the Terrazzo was dry in no time and therefore ready for sealing. For sealing I had selected Tile Doctor Colour Grow which not only seals the floor but enhances the colours of the stone segments to achieve a beautiful result.

Once done the floor looked cleaner, lighter and all the little characterful motifs really stood out. The customer contacted me a week later to say that the estate agent was delighted with the decision to go ahead with the floor restoration as it had certainly transformed the floor.

Victorian Terrazzo Kitchen Floor Before and After Restoration Penarth

Renovating an 1890’s Terrazzo Floor at a Church Vestry in Penarth

Detailed below is a fine example of what can be achieved restoring old Terrazzo flooring. The work took place earlier this year in the Kitchen of a Church Vestry in Penarth where the floor dated back to the Victorian 1890’s. Penarth is the wealthiest seaside resort in the Cardiff area and the second largest town in the Vale of Glamorgan, next only to the nearby Barry.

During the Victorian era Penarth was a popular holiday destination, known nationally as “The Garden by the Sea” and was often packed by visitors from the Midlands and the West Country. Along with the day trippers from the South Wales valleys, mostly arriving by train. Today, the town, with its traditional seafront, continues to be a regular summer holiday venue but with fewer visitors.

The client wanted a deep clean and shine finish, the floor had never been cleaned properly and as you can imagine it had a lot of footfall over the years and it really needed doing professionally. I visited to look first and carried out a small test clean to see how it would come up. Satisfied with this they were happy to accept my quote and we booked to return the following month.

Cleaning a Terrazzo Tiled Vestry Floor

With the aid of a rotary floor buffer I started the cleaning process with the application of a coarse 50-grit pad. The pad was run over the floor using a strong dilution of Tile Doctor Pro-Clean for lubrication. Pro-Clean is a concentrated, multi-purpose alkaline cleaner, which strips and degreases the floor. It is first left to dwell for 10 minutes or so and then agitated with the machine. Applied with the pad it cuts through old sealers, coatings, and of course ingrained dirt.

This process generates a lot of soil which is rinsed off with water and extracted with a wet vacuum. This was then followed by repeating the process with a 100 and then 200-grit pad. The area was given a thorough rinse with water and then dried as much as possible with the wet vacuum.

Some repairs were then carried out at the edges of the Terrazzo floor which involved sympathetically filling with cement. Once this had hardened the floor was treated to a burnish using finer grits of Tile Doctor burnishing pads ranging from 400, 800 and 1500 grits rinsing and extracting with water after each one.

After a final rinse, the floor was dried as much as possible with the wet vacuum and then left to dry off fully overnight, we would return the following day to carry out the sealing.

The next day I was concerned the floor might not be dry enough after using so much water to clean it previously so before applying the sealer I checked the moisture levels with a damp meter. The readings were within tolerance however my next step was to give the Terrazzo a further polish with a 3000-git pad which is applied dry so would further dry the floor and bring up the surface appearance.

The last task was to seal the floor and for this we selected to use Tile Doctor Colour Grow, this is a colour intensifying impregnating sealer which soaks into the pores of the stone and provide durable stain protection. This product will cope well with the needs of a kitchen and is fully breathable which is important when choosing a sealer for old floors which do not have a damp proof membrane installed.

Two coats of colour grow were applied to the Terrazzo, allowing about thirty minutes drying time before applying the next. After the second coat had dried the floor was treated to an application of Tile Doctor Shine Powder which is buffed into the floor using the rotary machine to achieve a super durable and deep lustre to the floor.

The Terrazzo responded very well to the treatment and the sealers applied will ensure it keeps its appearance for many years to come.
