Terrazzo Hallway Floor Restoration Cardiff

Terrazzo floor restoration in Cardiff

The owner of this property is an architect living close to myself in the centre of Cardiff. He approached Tile Doctor late last year about the restoration of a Terrazzo hallway floor. He recently purchased the property which was built around 1910 with an aim to restore the whole house back to its original condition and he wanted to preserve as many original features as possible.

Terrazzo Floor Before Restoration Cardiff

I went over to the property to survey the floor and carried out a cleaning test on a small part of the flooring to show him the potential result I could achieve. Whilst I was there, I measured up the Terrazzo which extended throughout the downstairs hallway and through to a matching section at the front of the property.

Happy with the result of the test clean I worked out a quote for restoring the whole floor, which was accepted, and a date set for the new year. The floor was one of many projects being caried out at the property which was unhabitable at the time so it would be just a question of picking up the keys and letting myself in.

Cleaning and Repairing a Terrazzo Tiled Hallway

My first task was to remove as much plaster and paint from the floor as possible with a sharp bladed scraper. Then I started scrubbing the floor with a very coarse 50-grit pad fitted to a rotary machine. The pad is applied with water for lubrication and run over each part of the floor several times. The floor is rinsed and extracted with a wet vacuum and the whole process repeated with a finer 100-grit pad and then a 200-grit pad.

Moving up the grits the next stage was to scrub the floor to remove staining with a 400-grit burnishing pad using a strong 50:50 dilution of Tile Doctor Pro-Clean. The pad was applied as before, rinsing and extracting once done and then moving up to the 800 and then 1500 grit pad.

As the floor became cleaner the cracks and damage to the terrazzo became clearly visible and so I started on repairing the cracks with a colour matched filler designed for this type of work. This was left to dry hard and sanded lightly until level with the floor.

The floor was then left to dry overnight, and I returned the next day to apply the last burnishing pad which was a very fine 3000-grit polishing pad to achieve the desired shine, also to polish out any light marks.

Sealing a Terrazzo Tiled Hallway in Cardiff

The sealer we selected was Tile Doctor Colour Grow which is an impregnator that soaks into the Terrazzo occupying the pores and preventing dirt from residing there. The sealer achieves a durable hardwearing finish and enhances the natural colours in the stone chippings it also ensures the dirt will remain on the surface where its easily cleaned away.

Once done I returned the keys, and the architect contacted me later to congratulate me on the restoration of the finished floor. For after care cleaning of polished Terrazzo I recommended the use of Tile Doctor Stone Soap which is a mild but effective floor cleaning solution that helps maintain the patina.

Terrazzo and Quarry Tiles Restored at a Fire Damaged Church in Bath

Back in June, I had the absolute pleasure of undertaking a large scale tiled floor restoration at St. Mary’s Church in Bath. An architect who does a lot of commissions in Bath and the surrounding areas got in touch with me as they needed to restore the very weathered and worn Church flooring, which dates back to 1840.

The Church itself had suffered a lot from fire damage and the Terrazzo flooring had lost any shine due to both exposure to the smoke and, of course, a lot of wear and tear over the course of 176 years. There were also a number of missing tiles that needed to be replaced.

In addition, some old carpet which was beyond repair had been pulled up to reveal some fantastic red Quarry tiles that the architect hoped could also be restored. They had discovered that some of the tiles had been removed in front of the Altar (an area of around 2.5 square metres) and cemented over due to the Altar being moved back a metre.

Fully restoring both large areas of tiled flooring would take time however with numerous contractors and trades also working in the building at the same time I completed the work in stages over a period of two months.

Cleaning and Sealing Terrazzo Tiles

To begin, I took moisture readings over all areas due to be worked on. In some places, the levels of moisture were high for two reasons: first, a significant amount of water had been used to quell the fire, and second the red Quarry tiles had been laid with no damp proof membrane due to the age of the building.

Next, I liaised with the architect to decide what tile and pattern would be best to replace the cement area in order to compliment the surrounding red tiles. We decided on a similar shape and colour from original style. I then removed the cement, re-cemented and tiled the area accordingly. Following this, I removed the badly damaged Terrazzo tiles and replaced them with spare replica tiles that the architect had leftover from previous projects.

My method for restoring the Terrazzo tiles was to use the Tile Doctor four pad burnishing system, applying each diamond encrusted pad in turn – from Coarse to Very Fine – to clean and polish the stone. I then sealed the tiles with an impregnating sealer known as Tile Doctor Colour Grow which enhances the natural colours in the stone. Finally, I went over the tiles again with the Very Fine burnishing pad to refine the shine. Needless to say, I checked for moisture before sealing, and thankfully the floor proved dry.

Cleaning and Sealing Red Quarry Tiles

In some areas, the red Quarry tiles had glue on them from the carpet being stuck down for many years. I manually scraped off the large, tough glue residues, and once this had been done, I used Tile Doctor Remove and Go combined with Tile Doctor Pro Clean to soften and break down any particularly stubborn glue deposits. After rinsing the floor, I went over it again with the Coarse grit burnishing pad to give the surface a really good clean. The remaining Quarry tiles were cleaned by using the same Coarse grit pad. using water to lubricate the process and rinsing periodically as I worked.

Having cleaned the tiles, I left the Church for a week to allow the builders and other trades to finish their work. Upon my return, I ran some damp tests to and found the readings were sky high, meaning sealing was not an option at this time. I discussed this issue with the architect and we decided to carry on with the completion in a month, leaving the floor enough time to dry out and for any other building work to be completed. By that time, the heating system would have also been installed and would work to help the floor to dry out quicker.

A month passed, and I returned to seal the Quarry tiles. However, before doing so I noticed efflorescence in some areas and neutralised it using Tile Doctor Acid Gel. I then left the floor a further two days to dry, by which time the Acid Gel had successfully removed all traces of efflorescence. To my satisfaction, the moisture readings I took upon my return were low, meaning the tiles were ready to be sealed.

To seal the tiles, I applied several costs of Tile Doctor Colour Grow, an impregnating sealer which helps protects with no damp proof membrane, follows by a few coats of Tile Doctor Seal and Go, a sealer which prices a nice satin shine finish. This really enhanced the old fire red pigment in the tiles.

While it was a long and difficult process to fully restore both sets of tiles, the outcome was very much worth the wait. Looking at the before and after photographs, it’s easy to see why the architect, priest and the parishioners were absolutely delighted with the results. I’m also really pleased to have contributed to the restoration and continued conservation of this wonderful building.

Deep Cleaning a Terrazzo Hallway near Caerphilly Castle

I previously restored an Quarry Tiled floor for the owner of this residence near Caerphilly Castle and was asked back to deep clean their Terrazzo hallway floor which was far from looking its best.

Restoring a Terrazzo Floor

Terrazzo is a very hard surface and needs to be burnished to get the best results so after scrubbing the floor with Tile Doctor Pro-Clean and a black scrubbing pad to remove what felt like 100 plus years of black dirt I set about burnishing the floor with a set of diamond encrusted burnishing pads and a little water. The set comprises of four different grades of diamond pads ranging from coarse to smooth that produce a shiny clean surface. The floor is rinsed between pads to remove any slurry from the process and given another rinse at the end.

The hard Terrazzo soon dried and I was able to seal the floor with the application of three coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer which will prevent staining and make it easier to clean in future. Once the last coat was dry I and gave the floor a further polish with the 4th stage green pad to give a true deep shine.

I think you will agree that what was once an old and tired terrazzo hallway floor now looks much better following its facelift, something that was only made possible due the quality of installation when first laid.
