Jerusalem limestone Floor Polishing Mortimer Common Reading

Pitted Jerusalem Limestone Floor Renovated in Mortimer Common

I was called out to a property in Mortimer Common, which is a few miles West of Reading to survey a Jerusalem Limestone floor that had been installed quite some time ago when an extension was added to the property.

Over time their once beautiful Jerusalem limestone floor had become dirty, dull and in areas chemically damaged. In an attempt to freshen up the stone floor the customer brought some sealer from a local trade store and applied it to the floor, however the product she purchased was actually a topical sealer (Polish) which left the floor looking worse, in her words made the natural stone looking “artificial”. On very rare occasions topical sealers can be used on honed/polished floors but can easily go wrong that’s why we recommended using impregnated sealers when working on this type of material.

Limestone is also acid sensitive so best to avoid the use of strong acidic cleaning products such as bleach which will etch into the stone with use and in some cases open naturally forming cavities in the stone itself, a problem we often refer to as pitting.

My first task was to remove the topical seal that was recently applied and deep clean the dirt filled pits and grout. To do this I used a strong dilution of Tile Doctor Remove and Go left it to soak in for ten minutes and then agitating using a combination of a stiff nylon brush and a Black stripping pad fitted to a rotary machine. I made sure to go over any pits in the stone multiple times to release the trapped dirt. The resultant slurry was vacuumed up as I went along and the floor given a rinse with water afterwards.

Once clean I addresses the small pits in some of the tiles by backfilling them with a rapid setting filling compound that I colour matched with various shades of brown and cream.

With the old sealer removed and the holes/pits taken care of I continued with the restoration of the floor by moving onto the burnishing process which cleans and polishes the stone. This involves honing the Limestone with a set of burnishing pads starting with a course 400-grit and finishing with a fine 3000-grit. The pads are applied to the floor with a heavy floor buffing machine using water to lubricate the process. The pad is run over each tile around five times and the chalky slurry this process generates is rinsed off afterwards with water and then extracted with a wet vacuum. You then move onto the 800-grit and then 1500-grit slowly building back the appearance of the stone.

Once each of the three pads had been run over the floor it was given a final rinse and then dried as much as possible with the wet vacuum before leaving it to dry off fully overnight.

We returned to the property the following day, by which time the floor had dried completely. I finished the burnishing process with the fine 3000-grit burnishing pad which is brings up the polish even further and is only applied using a little water sprayed onto the tiles.

Once done I moved onto applying the sealer which for this floor, I chose Tile Doctor Colour Grow. This is an impregnating sealer that soaks into the pores of the stone to provide durable protection whilst enhancing the natural colours in the stone. The customer was over the moon with the results and was stated the floor looked better than when it was installed all those years ago.

For aftercare cleaning I recommended the use of Tile Doctor Stone Soap which is designed for maintaining the patina on polished stone floors.

Stunning Indian Slate Floor Renovated in Bradfield Kitchen

Details below of a very heavily soiled Indian Slate floor at a property in the small village of Bradfield near Reading. The floor had been cleaned a couple of years before, but the client said they were never completely satisfied with the result and suspected the old seal hadn’t been removed completely before the new one was applied.

I was quite sure I could improve the appearance significantly, so I arranged to call in and survey the floor. Whilst there I carried out a test clean on a small part of the floor which came up well. I provided a quote to complete the work, and they were happy with the price, so the work was booked in.

I started by applying a strong dilution of Tile Doctor Pro-Clean which was left on the Slate for ten minutes before being scrubbed in with a rotary machine fitted with a black scrubbing pad. I used a strong dilution in order to strip the old sealer off the stone and during this part of the renovation I was able to confirm that the recent seal had been placed on top of the old discoloured seal. Tile Doctor Pro-Clean did a fantastic job on the first layer but I needed to use something stronger to remove the thicker layers of seal underneath.

I applied Tile Doctor Nanotech HBU Remover on a small area before covering with plastic sheeting, this allowed the product to slowly break away at the old seal. Some areas had to be treated twice. It was difficult work so I can see why the other company had given up, but I was determined to achieve a uniform look throughout the floor.

Once the old sealer was broken down, I added water and turned my attention to scrubbing the tiles and grout with a rotary machine this time fitted with a nylon brush. I then extracted the wet slurry with a truck mounted extraction system.

I slowly worked my way through the kitchen/diner and utility room until the whole area was stripped back and looked uniform. The floor looked completely different. The floor was left overnight to dry out before we could tackle the sealing process.

After reviewing pictures of previous slate renovations, I had completed my client selected Tile Doctor Seal and Go as the product to seal their floor. They were keen to use something that would allow the natural colours of the stone to shine through. Seal and Go works really well on Slate floors leaving the stone with a subtle satin finish as well as proving durable protection from staining.

I applied six coats of sealer using a combination of small rollers and an applicator pad allowing 30 minutes to dry between each coat. The roller was to ensure I got the seal within all the groves that semi riven slate has and smoothing it out with a paint application pad.

Once completed the floor looked stunning and my customer was very pleased to say the least. They couldn’t believe how bright and colourful the slate had become so much so he left the following feedback

“Dennis did a wonderful job with our kitchen & utility room which is Indian Slate I might add it hadn’t been attended to for a number of years, so it was very challenging for Dennis and the result was outstanding we now have a new floor. What a great guy Dennis his client care was second to none and the dog liked him”
