Black Limestone Floor Ruined by Coffee Machine Descaler, Stratford upon Avon

I really felt for this customer who was mortified after accidentally spilling limescale descaling solution on their beautiful Black Limestone floor in Stratford upon Avon. The problem started when attempting to descale a coffee making machine in the kitchen, unfortunately the bottle fell out of his hands and onto the Black Limestone floor, the subsequent attempt to mop it up spread the problem across the floor.

Descaling solutions contain strong acids that dissolve the minerals in limescale so they can be easily removed. Limestone being of a similar structure is equally effected however in this case the product was removed quickly and didn’t have time to etch the stone. Unfortunately, the descaler did have time to upset the factory polish leaving a right mess and ruining the appearance of the stone.

I went over to survey the floor and reassured my customer the floor could be restored. There are several products and methods that can be applied to resurface and polish stone floors, so I knew the problem was repairable, it was just a question of finding the best solution for the customer.

Stripping Sealer from Black Limestone Flooring

I reasoned that the underlying stone was not etched by the acid, it was the wax-based factory finish that had been upset so the best course of action would be to strip back the entire floor to the bare stone and then reapply a new sealer that would provide a similar appearance.

To do this I started with the application of Tile Doctor Remove and Go across the whole floor. This product is a coatings remover that is specially designed for use on Tile and Stone, it was sprayed onto the floor and after ten minutes scrubbed in using a rotary machine fitted with a scrubbing pad. The resultant slurry was then rinsed off with water and extracted using a wet vacuum. This process was repeated until I was confident that the factory polish had been removed.

Next step was to strip the stone of the black dry added by the factory by giving it an acid wash using Tile Doctor Acid Gel. This was necessary to rebalance the appearance of the stone across the entire floor and would result in a consistent appearance one resealed. The Acid Gel was scrubbed into the Limestone, then rinsed off and extracted using the same procedure as before.

After a final rinse the floor was left to dry off overnight.

The next day I first checked the floor was dry using a damp meter, there were no excess moisture issues so I able to go ahead and seal the stone using a product that would bring back the colour and add protection against dirt and staining.

The best product for this was Tile Doctor Colour Grow which is an impregnating sealer that seeps into the pores of the stone protecting it from within and enhancing natural colour at the same time. The only disadvantage of this product is it leaves a matt finish whereas my customer wanted the shiny, easy to clean appearance of the original tile. To resolve I recommended we leave the floor to settle for a while and if no issues develop, I would add a couple of coats of Tile Doctor Seal and Go which is compatible with Colour Grow and would give the desired finish.

Due to various commitments on both our parts it was six weeks until I was able to return and top up the sealer with Seal and Go. It was worth waiting for and much to the relief of the owner his Black Limestone floor has been transformed to new again.

Pitted Jerusalem Limestone Floor Renovated in York

Jerusalem Stone is a pale variety of Limestone that comes from Israel and is available in different colours. It’s a high-quality material that has been used in construction for thousands of years however like all Stone used as flooring, it benefits from being sealed to prevent dirt from becoming ingrained in the stone.

Jerusalem Limestone Before Cleaning York

This ground floor of this house in the historic walled city of York had around 60 metres of Jerusalem Limestone installed throughout the kitchen area and some adjacent steps. Its appearance had degraded with use and was now looking flat, dirty and generally uninviting. Additionally, the customer didn’t like the natural pitting in the stone which proved to be a trap where dirt became ingrained making it more difficult to clean.

I surveyed the floor and discussed the process required to restore the floor including restoration work to fill the pitting. I also worked out a price which was agreed and booked a date in the diary for the work to be done.

Cleaning and Filling a Jerusalem Limestone Tiled Kitchen Floor

My first task was to fill the holes using three different colours of grout. The floor was a mixture of shades, so I chose the best match based on the different colours in the stone. This work was tedious and a little slow but worked well and I was very pleased with the result. I come from a Tiling background so am quite used to working with grout in this manner.

Next the floor was deep cleaned with the 400, 800 and 1500 grit diamond burnishing pads fitted to a weighted floor buffer and lubricated with water. The pads are applied in sequence starting with the 400-grit pad first and the soil generated is rinsed off with water in-between. This process removes grease marks, old sealers, ingrained dirt and builds the polished finish of the limestone. I also used a hand-held burnishing block on the steps to get into the intricate corners.

The grout was particularly dirty and was cleaned by hand using Tile Doctor Pro-Clean scrubbed in with a narrow stiff brush and the soil rinsed off with water and extracted with a wet vacuum. This product is a multi-purpose cleaner and degreaser and it really gets to work on the hard to shift build-up of dirt, grime and grease.

The floor was left to dry off overnight, the lovely warm weather was a blessing as the floor was pretty large, thankfully we didn’t need to install any driers on this occasion.

I returned the next day to finish the polishing with the final 3000-grit pad applied with a little water sprayed onto the tile. once done I tested the floor with a damp meter to make sure it was nice and dry and ready for sealing. The filled areas were looking particularly good, eliminating the issue the customer was having with dirt getting stuck in them.

To seal the Jerusalem Limestone and protect it from ingrained dirt I used two coats of Tile Doctor Ultra-Seal which is a natural look sealer that doesn’t alter the appearance of the stone. As well as providing the natural no-sheen look that the customer wanted it will provide stain protection and is recommended for food preparation areas such as kitchens. It also was excellent for sealing the grout and the areas I had filled.

The customer was very happy with the result and couldn’t believe how fast we had worked to restore the floor. She was relieved it would now be much easier to clean and maintain.

Polishing a French Limestone Floor in Eldwick, West Yorkshire

I was recently contacted by a lady in the small village of Eldwick near Bingley who wasn’t happy with the condition of her French Limestone floor which had hadn’t been professionally cleaned for some time. The French Limestone tiles had been laid throughout the kitchen and dining room and as you can see in the photograph below now looked dull, dirty and uninviting.

The floor needed a deep clean and seal to bring it back to its’ best however before I could do that I needed to determine the best method to use. I duly carried out a survey and test clean which showed how the floor could be improved and discussed the quote for the work with the client, they were really pleased with the test area, accepted the quote and we arranged a convenient time to carry out the work the following week.

Deep Cleaning a French Limestone Tiled Floor

Arriving on site a week later, my first task was to cover all the kitchen units with protective covering to protect against splashing. The last thing we want is to cause any damage to the surrounding areas.

The next step was to use a set of diamond burnishing pads from Grits 400 to 1500 to clean and polish the Limestone tiles. The pads are fitted to a rotary buffer and applied in sequence with water to lubricate, the process removes inground dirt and rebuilds the polish on the Limestone. Small hand-held burnishing blocks are used to reach the more intricate areas. The floor is then rinsed with more water after each pad has been used and the resultant residue is removed with a wet vacuum.

Once I was satisfied that the dirt had been removed from the floor, I then worked on the more stubborn grout lines with a strong dilution of Tile Doctor Pro-Clean and a stiff grout brush to get any remaining deposits out of the grout lines. This is a great multi-purpose high alkaline cleaning and stripping product brilliant for heavily soiled and stubborn neglected tiles and very good on very dirty grout. With the grout clean I then applied the last 3000 grit burnishing pad to really bring up the polish on the Limestone floor, this pad is applied dry with a little water sprayed onto the surface of the stone. The floor was then left to dry off completely overnight.

The following day I checked that the floor was dry using a moisture meter before applying Tile Doctor Ultra-Seal to the floor. This is a premium, no-sheen, natural-look penetrating sealer which is formulated to provide maximum stain protection, it’s also recommended for busy kitchen areas and is an excellent grout sealer. Once the sealant was dry I did a water drop test to confirm that the floor was properly sealed.

I hope that you can see from the photos the improvement in the appearance of the floor. The client was really happy with the floor which lifted the whole room and made the kitchen like new again.
