How to Restore Old Quarry Tiles Covered by Vinyl

The owner of this property in the South London suburb of Cheam got in touch about restoring a Quarry tiled floor that had been covered with Vinyl tiles. After surveying the floor, it became clear that some of the original Quarry tiled floor was missing and had been replaced with concrete before covering with Vinyl.

To fully restore the Quarry tiles floor, it would therefore be necessary to dig out the concrete sections and tile with matching quarry tiles which had been supplied by the client. Once done we would then need to renovate both the old and the new sections of floor and seal them to achieve a consistent appearance. I was also asked to dig out an old matwell and prepare it for a new mat as part of the work.  

This was a large job, but following a site visit I was able to provide my client with an accurate price and arranged a time to carry the work out which would take five days.
    

Removing Vinyl Tiles

The first part of the job was to lift the existing Vinyl tiles which had been laid on top of the Quarry tiles. I used a heat gun to help loosen the adhesive and then assisted with a steamer scrubbed Tile Doctor HBU Nanotech stripper into the floor to remove the glue and bitumen from the surface of the newly exposed Quarry tiles.

The soiled solution was extracted with a wet vacuum and I followed up by giving the Quarry tiles an acid rinse using Tile Doctor Acid Gel. The Gel is applied to the tiles and then scrubbed in with a Black pad fitted to a rotary machine. This process removes old traces of cement and grout from the quarry tiles and further cleans them up. After this the floor was rinsed thoroughly and the soil extracted with a wet vacuum.

The next focus was on digging out the concrete areas mentioned earlier and then preparing the subfloor for tiling with self-levelling compound, which of course needs time to set. Once ready the replacement tiles were fixed in place making cuts as necessary and placing them to follow the original floor pattern. This may sound quite this sound straight forward, but this part of the job took some time to complete. The floor was left for a couple of days so the new tiles could set and the whole area could dry out before sealing.

I returned later to seal all the Quarry tiles with Tile Doctor Colour Grow which brings out the deep Orange colours in the tiles whilst adding protection from staining and ingrained dirt. This sealer works by occupying the pores in the tile so dirt cannot become ingrained there. Four coats of sealer where applied across the whole floor leaving a nice matt finish that was consistent across the whole floor.

Before leaving I discussed with the client the best way to maintain the floor in the future and recommended the use of Tile Doctor Neutral Tile Cleaner which is a pH neutral cleaner. This is important as its gentle enough to use frequently and won’t strip off the newly applied sealer like many household floor cleaners will. Its supplied in concentrated form so a small amount of cleaner goes a long way.

The client was delighted with the results, they were very pleased to see the back of the tired Vinyl floor and pleased the floor now looked consistent throughout.

How to Remove Screed and Bitumen from Stone Floors

The owner of this Flagstone floor at a property in Carnforth was told by a damp specialist to remove the carpet and underlay and have the floor taken out and skipped. Then to install new hardcore and concrete put in place but with a Damp Proof Membrane installed in between, then once fully cured (four weeks at least) they could have a new carpet, tile or wood floor etc. installed. All good advice, however, the owner of the house wanted to keep as many original features as possible and wasn’t keen on the proposal.

Looking for an alternative solution they reached out to Tile Doctor and so I went over to take a look. After surveying the floor, I came up with a completely different solution which involved milling the stone with coarse abrasive pads to remove the screed and bitumen and then resurface with diamond encrusted burnishing pads of medium and fine grits which would result in a smooth finish. Not only would this be much easier to clean going forward it would also be much more attractive, especially once sealed.

Happy with our alternative we arranged a date to come and do the work which would take three days, two days to prepare the floor and a third to apply a sealer.


Cleaning a Flagstone Tiled Ground Floor

Milling a floor is arduous work and requires the use of a heavy rotary machine that can apply weight onto the stone so the milling pads can really get a bite into the surface. Because of this I roped in a colleague to help take some of the strain. Some of the areas of bitumen and screed were so prominent we used an SDS hammer action drill with a flat bit to chisel them off first, this can leave a few marks in the stone which we then level out with the milling pads starting with a 50 grit and go all the way up to a 400 grit.

We used a lot of water during this process to help lubricate the abrasive action of the milling pads, this also helps to rinse off the soil that is created, all of which is extracted with a wet vacuum.

Next step is to give the floor an acid rinse with Tile Doctor Grout Clean-Up which is designed to neutralise any alkaline salts in the stone that could result in efflorescence later.

With the floor cleaned up the last step was to re-point between the Flagstones using a breathable pointing product called GFtK 800.

Sealing was the next step however the floor was still quite damp after the initial renovation, so it was left for a few days to dry out first.

We selected a fully breathable sealer for this floor, this is an important requirement for a floor with no damp proof membrane as it will allow moisture to rise through the flagstone and evaporate at the surface. The concrete screed and bitumen covering will have prevented this previously which is dangerous as a build up of moisture in the stone can lead to it crumbling and you risk moisture reaching out to the walls where it can lead to rising damp. 

Tile Doctor has three breathable sealers to choose from and in this case the customer decided to go with Tile Doctor Colour Grow which is an impregnating sealer that protects from within and enhances the natural colours in the stone.

The floor was completely transformed by the end of the third day, you would not have known it was the same floor. It was now clear of all the previous coverings and now looked like a characterful old Flagstone floor should.

Before leaving I recommended, they use Tile Doctor Neutral Cleaner for everyday cleaning, being pH neutral it won’t prematurely erode the sealer allowing it to work for longer. I also advised that it’s possible that parts of the stone may go a shade darker in winter and a shade lighter in summer due to the moisture rising through the floor.

How to Repair and Restore a Victorian Tiled Hallway

Earlier this year I was asked to quote for repairing and restoring a Victorian Tile Hallway in St Neots. The floor was in good physical condition for its age however a section of tiling had been removed so facilitate the installation of a new pipe. The contractor was not very sympathetic to the old floor and after removing the tiles and installing the pipe they had simply back filled with concrete ruining the overall look of the floor.

The rest of the Victorian Tiled Hallway had not been properly cleaned and sealed in some time and any protective sealer had long since worn off in the busier parts of the hallway. Without a sealer in place dirt had penetrated the pores of the tile leaving them looking dull and impossible to keep clean.

Period features like this floor are very desirable these days and understandably the owner was every enthusiastic to have the floor fully restored back to its best possible condition.

I discussed with him the work we needed to do, which included repairing the concreted sections, deep cleaning the floor and then finish with the application of a protective sealer. I was confident I could source similar tiles and would be able to get the floor looking great again. We agreed a price and booked the work in to be carried out.

Repairing a Victorian Tiled Hallway Floor

I started by manually removing all the concrete at the back of the hall with a bolster and hammer. Once cleaned of rubble the hole was filled with a self-levelling compound to even out the area in order to get the surface to the right level ready for tiling.

Fortunately, I had managed to source nearly identical tiles to replace the missing ones. There are a few places that keep stock, so it makes it easier to restore this type of floor. The border was laid first followed by filling in the middle with the correct pattern.

Deep Cleaning a Victorian Tiled Hallway Floor

Once grouted the whole floor was stripped and cleaned using Tile Doctor Remove and Go which is a coatings remover that is designed to clean and remove old sealers from tile and stone. The product is diluted with water, sprayed onto the tiles and then allowed to soak in for ten minutes before scrubbing it in. The solution soon turns into a dark slurry as the dirt is released from the pores of the tile and this is then rinsed off with water and extracted with a wet vacuum.

The next step was to treat any potential efflorescence problems that may appear later due to the lack of a damp-proof membrane under the floor. This is quite a common issue with old floors where moisture can rise through the tile carrying with it salts from the sub floor. To counter this problem and neutralise the alkaline salts the floor is further cleaned with Tile Doctor Grout Clean-up which is an acidic product. To remove the product another round of rinsing and extracted is carried out.

During the cleaning I noticed that some of the tiles had damage to the surface from being concreted over, so I renovated the surface using a 200-grit burnishing pad that hones the tile. Once I was happy the floor was clean, I left it to dry off for two days.

I came back to seal the floor first checking with a damp meter that the moisture levels in the tile were below an acceptable level. All was well so I started the application of the sealer with a base coat of Tile Doctor Colour Grow which is an impregnating sealer that will deepen the colours and add an extra layer of protection.

Once the first dry coat of Colour Grow was dry, I followed up with five coats of Tile Doctor Seal and Go which adds further layers of protection and leaves the tiles with a nice subtle sheen.

The job took five days in total, three days to sympathetically repair the floor followed by two days to clean and seal. You can see from the pictures that the repaired area looked very original and overall the floor looked great and the pattern is stunning. For aftercare I recommended they kept the floor clean using Tiles Doctor Neutral Tile Cleaner, this will keep the floor clean and ensure the sealant isn’t eroded prematurely which can happen with stronger floor cleaning products.

The customer over the moon with the results and left the following glowing testimonial for me on the Tile Doctor feedback system.

”Tom was professional, meticulous, polite and hard working. We would have no qualms about recommending his service to others - especially with mosaic Victorian flooring like ours. Good value and plenty of expert advice and guidance thrown in for free. Thanks Tom. By Alden W, St Neots”
