Glue Stained Sandstone Hallway Restoration in Carbrooke, Norfolk

This was perhaps the most challenging restoration we have been presented with to date.
The work involved removing carpet and underlay from a long Yorkstone tiled hallway at a beautiful old Grange in Carbrooke on the outskirts of Watton and restoring the flagstones to their original glory. These pavers are a type of Sandstone, a carboniferous sedimentary rock consisting of quartz, mica, feldspar, clay and iron oxides quarried in Yorkshire and having a rich sandy colour with a slightly sparkling surface.

On lifting the carpet, we found, to our dismay, that the rubber-backed underlay had been firmly stuck down to the surface of the stone with what appeared to be a thick layer of yellowing impact adhesive which covered the entire area right up to the thresholds and skirting boards.

Stripping Carpet Adhesive off a Sandstone tiled floor

Our first task was to remove as much of the underlay by hand using sharp-bladed scrapers and a heck of a lot of elbow grease. Having done this, the next step was to cover the remaining adhesive layer with a specialist water-based stripper which was applied by brush and allowed to react for an hour. The result was an incredibly sticky substance with the consistency of chewing gum which we had to painstakingly remove inch by inch with paint scrapers. This process had to be repeated twice as even the specialist stripper couldn’t cope with the sheer volume of goo in a single application. The floor was then left overnight to dry out and settle down.

The following day, we deep-cleaned the whole area using very strong mix of Tile Doctor Pro Clean and Remove & Go, scrubbed in with a rotary machine fitted with a black stripping pad. Four pads were used up in this process as they quickly became clogged with the thick slurry which was then power rinsed and vacuumed away from the floor. Any remaining patches of the glue were further softened using Tile Doctor Nanotech HBU Remover and carefully picked off by hand with the bladed scrapers.

Finally, the slabs were finished using a brush fitted to the rotary machine with 320 grit honing powder to achieve a smooth, silky and very clean surface before being power rinsed with plenty of clean water. Again, the floor was left to dry thoroughly overnight with the assistance of our large capacity dehumidifier and thermostatic hot air blower.

Returning the following day, we found that the dehumidifier and heater had done their job and the sandstone was ready for sealing, the moisture content having been brought down to an average of 10% overall as shown by our damp meter testing.

The client had requested a light shine on the floor so that it would be easy to maintain on a daily basis. We chose, therefore, to use Tile Doctor Seal & Go, a combination sealer with a mid-sheen topical finish, which we applied using paint pads and microfibre cloths in five thin coats, resulting in an excellent fluid resistant seal with a lustrous shine.

This was a tough job but a highly satisfying result, further emphasised when the client’s antique furnishings were placed in situ.

Expert Sandstone Cleaning in South London

Details below of a Sandstone floor installed in the Kitchen of a house in Clapham, South London. The client had not been happy with the floor since it had been installed because the tiler hadn’t applied the seal correctly. The owner had also had a quote from a stonemason who had recommended grinding off the top later of stone. I explained that that would not be necessary and went on to explain the process to restore it. As it turns out my quote was £500 cheaper that the Stone mason but I was confident I could get as good a result and the customer could see I knew what I was talking about and gave the job to me.

I began work on the floor using a coarse diamond burnishing pad fitted to a rotary scrubbing machine with a little water. I slowly scrubbed the floor in small areas and removed the old sealer from the whole tile. The next step was to tackle the grout which was done by applying Tile Doctor Pro-Clean worked in along the grout lines using a stiff grout cleaning brush. After this the pad was replaced on the rotary machine with a medium brush head and the floor was given a good scrub followed by rinsing thoroughly with fresh water.

At this stage it was evident that a couple of stubborn areas were still in need of attention due to the old sealer still being present so Tile Doctor Remove and Go was applied which is a strong sealer stripper and left to dwell for around 40 minutes before being scrubbed in and washed down again.

I can recommend a Wet Vacuum at this point as they are great at removing liquids from floors; at this point I left for the day to allow the floor to dry overnight ready for sealing the next day.

Then next day when I returned I checked to make sure the floor was dry and ready to seal, there were a couple of little patches I needed to redo and once they were rinsed I dried them using my heat gun. I then sealed the floor with four coats of Tile Doctor Colour Grow and when the last coat had dried I demonstrated to the customer that it was fully sealed using a water test.

The client was really pleased with the results and that I had saved him so much money and left the following comment on our feedback system.

Bill was great and worked hard to restore and protect the floor. We’re very pleased. There has been some accidental damage outside which I’m happy we’ll sort.

Maintaining a Sandstone flagstones

This customer in Hannington had a badly soiled and stained rough sandstone tiled floor which they were finding extremely difficult to keep clean. It was apparent that the previous sealer was no longer working well and so the only solution was to strip and clean the floor then re-seal.

Cleaning a Rough Sandstone Tiled Floor

I stripped the floor using a strong dilution of Tile Doctor Pro-Clean combined 50/50 with NanoTech UltraClean to produce a strong stripper and cleaning solution that is safe to use on natural stone. This was worked into the tile using a rotary machine fitted with a scrubbing brush rather than a pad to cope better with the uneven finish of the rough Sandstone.

This activity was then followed with a high pressure spinning tool operating at (1200psi) in four to five metre square sections. The spinner tool washes the tile surface with high pressure water and also extracts the water from the surface simultaneously which dislodges and loosens built up ingrained grim from the tiles and grout.

The floor was now clean and free of old sealer and was left to dry for a couple of day aided by turbo fans and dehumidifiers which we left at the property.

When we came back we first tested the floor with a damp meter in a few different locations to make sure no dampness remained in the stone, fortunately the machines we had left behind had done their job and the floor was completely dry so we started to seal the floor. For this the customer had chosen Tile Doctor Seal and Go which adds a high gloss finish as well as lifting the natural colour in the stone.

This Sandstone tiled floor was installed in a house in Loughborough; the existing sealer on the floor had been worn down over time and it was becoming difficult to clean so we were asked to give it thorough clean and re-seal.

Cleaning a Sandstone Tiled Floor

We cleaned the floor using a dilution of Tile Doctor Pro-Clean, Pro-Clean has an alkaline formula so it’s safe to use on natural stone as opposed to mildly acidic cleaning products that can eat away at protective coatings and even dissolve calcareous stone over time. The solution was worked into the stone surface using a rotary machine fitted with a black scrubbing pad; we also used a stiff hand brush on the grout lines. The soiled solution was rinsed off with clean water which was removed with a wet vacuum and left to dry. At this point we noticed there were a few spots that needed further attention so we repeated the process until we were happy and then left for the evening so the floor could fully dry overnight.

We came back the next day and after checking the floor was dry proceeded to apply the sealer. For Sandstone I prefer to use Tile Doctor Colour Grow, it’s an impregnating sealer that penetrates deep into the stone, enhances the natural colour in the stone and provides good surface protection. I think you will agree from the photograph below it has really improved the look of the Sandstone.

Cleaning Sandstone Fireplace

We don’t get a great deal of inquiries about the restoration of stone fireplaces so its refreshing when one comes along, however the principles of cleaning and are the same so were always happy to take on the work.

Stone Fireplace Before Restoration

As you can see from the photograph above the Sandstone Fireplace was stained from soot and in need of a good clean. Soot staining is inevitable given the location however it can be reduced with wood burning stoves by fully opening the air vents shortly before opening the door, this reduces the amount of soot carrying gasses being released upwards and onto the stone when the opening.

Sandstone Fireplace Cleaning

Before cleaning the Fireplace we protected the surrounding walls using black plastic secured with decorator’s masking tape. The next step was to mix up a 50/50 solution of Tile Doctor Pro-Clean and Ultra-Clean which was decanted into a spray bottle and sprayed directly onto the stone. Pro-Clean is a heavy duty cleaner and stripper whilst Nano-Clean contains abrasive particles so together they form a useful cleaning product. The spray mixes the cleaning solution with air which makes it lighter and more able to stick to vertical surfaces. The cleaning solution was left to dwell on the limestone for 15 minutes, then scrubbed and rinsed. The final step was to seal the fireplace with Tile Doctor Colour Grow which is a colour intensifying sealer that will provide stain protection going forward, I think you will agree the difference was amazing.
