Removing Mould from Limestone Shower Tiling

Posted on by

I was asked to look at renovating a shower cubicle at a property in in Manchester city centre that had been clad in White Limestone tiles. I understood the bathroom had been installed 12 years prior, but now the tiles were looking grubby, mouldy and dirty.

The client had lived at the property for the last two years and in an attempt to resolve the problems had used a few different household products such as flash and bleach, they had tried everything, and nothing had helped. I suspected that these strong acidic cleaners had actually made the problem worse by stripping off what was left of the sealer that was protecting the Limestone, allowing dirt to become ingrained in the stone.

I visited the property and ran a few cleaning tests in the shower cubicle with Tile Doctor products. This allows me to see which product will have the best results and gives the customer confidence that we can resolve their issues. The results were immediate, they could see the difference and they were happy to accept my quote and agree a date for my return to complete the work.

I arrived several weeks later and made a start. The tiles were scrubbed by hand with a strong dilution of Tile Doctor Remove and Go with excellent results. This product is designed to remove coatings and sealers, and in this case, it did a great job of drawing out the ingrained stains and dirt build-up. This removed what was left of the sealer and took off most of the dirt and mould. The Limestone tiles and grout were then rinsed with water to remove the soil.

Next I needed to restore the smooth surface of the limestone which had been etched by the use of strong acidic cleaning products. To do this I used a set of six-inch diamond burnishing pads attached to a hand buffer to hone and restore the stone.

I then dried the shower tiles and grout with a heat gun checking the moisture levels with damp meter until I was satisfied it was completely dry.

The last step was to re-seal the Limestone and Grout using a couple of coats of Tile Doctor Colour Grow. This is natural coloured intensifying sealer which provides durable protection to the surface allowing it to breathe and enhancing the colours.

The Customer was amazed with the difference and left the following feedback!

“Kamila was friendly, professional and kept me informed about what to expect before she took on the job and during the tile cleaning. The tiles look absolutely amazing after her work – I feel as though I have a brand new bathroom! Kamila also gave me helpful tips on looking after limestone tiles. I can’t recommend her highly enough.”

For future cleaning I recommended the use of Tile Doctor Aqua-Pro which is a pH neutral shower tile cleaner designed for use on sealed surfaces. Most cleaning products you find in supermarkets are overly strong and will erode the sealer prematurely, so when choosing a cleaning product always read the label and make sure it’s safe to use on Sealed Stone tiles.

Renovating a Black Limestone Patio in Surrey

Posted on by

This customer from Farnham called me with three requests. First, can you clean and seal our Black Limestone patio? Secondly can you remove some scratches? and finally, can you make it less slippery as my children have slipped a couple of times in the wet.

After discussing the problems over the phone, we agreed a convenient date and I went along to the property to have a look. I could certainly do the first and second but not the third. There are products on the market but most Anti-slip products I’ve come across contain acids which etch and roughen the surface. Her patio was made of dark limestone which is acid sensitive and applying an acidic product would ruin the look of the stone leaving it looking washed out. I discussed with her the options and the process and we agreed a price, booking the work in for later in the month.

Cleaning a Black Limestone Tiled Patio Floor

First, I cleaned the grout lines with Tile Doctor Pro Clean which was left to soak in for about ten minutes before being scrubbed with a nylon brush and being careful not to further scratch the stone.

The next step was to clean the stone with a series of burnishing pads starting with a coarse 400-grit lubricated with water then moving onto increasingly finer pads of 800 and 1500 grit. It’s important to rinse and extract the slurry after applying each pad. This process removes the existing sealer and slightly mills the tiles firstly opening the pores then slowly closing them as the process continues. I avoided the dark area in the picture where the table was situated as it had been protected from the weather, sun and small children. My aim was to get the same consistent colour across the whole patio.

Once I had used the three pads, I completed a final rinse and extraction with a wet vacuum. I then checked surveyed the floor looking for any areas that needed more work and to verify that the scratched had been removed as part of the process. The work went well, and I was happy to see that the scratches had been lifted and the appearance of the stone looked much better and more even.

It was a warm day, so it wasn’t long before the stone had dried and were dry enough to be sealed. I talked through the customers options for sealing and recommended the application of Tile Doctor Colour Grow as it contains a colour enhancer which would return the dark colour to the stone and match the original colour under the table. Colour Grow is also rated for external use.

Two coats of Colour Grow were applied, and this made a big improvement to the appearance of the stone resulting in a stunning transformation. The customer was over the moon and with the patio now ready for the summer she could not wait to get the patio furniture in place and enjoy the space.

Removing Grout Haze from Limestone Kitchen Floor Tiles in Clipston, Northamptonshire

Posted on by

These photos are of a Limestone tiled floor which was installed in the Kitchen approximately at a property in the small parish of Clipston, which is close to the towns of Market Harborough and Daventry, three years ago. The customer was never very happy with it since it was laid as it never seemed to look clean asked me to cover over and work out what could be done.

On my initial visit I soon realised that the installer had not cleaned off all the grout from the tiles before applying the sealer. This effectively trapped the grout under the sealer and gave the whole floor a dirty appearance, this explained the problem the customer was frustrated with as she could never ever seem to get the floor looking clean.

This issue is known as Grout Haze or Grout Smears and is a problem we often come across where the floor has been laid without the excess grout residue being completely polished off the tiles after the grouting. Some manufacturers recommend the tiles are sealed before grouting to make it easier to polish the grout off later. After discussing how we could remedy this I issued a quote which the customer accepted, and we scheduled the work to be done.

Removing Grout Haze from Limestone Kitchen Tiles

I arrived on site on the arranged date, as it was a painted kitchen it was not possible to mask up the units, so I used a small hand-held polishing machine fitted with a six inch 400-grit burnishing pad to carefully clean around the edges and break through the sealant. This process was then repeated with a larger seventeen inch 400-grit burnishing pad fitted to a floor polishing machine throughout the rest of the area.

Once the original sealant had been removed using the burnishing pad the next step was to remove the Grout Haze by given the floor an acid wash with Tile Doctor Acid Gel. Being a gel, this product is easier to control than a liquid and sits on the surface where it’s needed to break down the unsightly Grout Haze. It’s left to dwell for a short period before being worked in with a special brush that is designed for this purpose. The resulting slurry is then removed with a professional wet pick up machine and the floor given a rinse with water to remove any trace of the product.

After treating the Grout Haze my next step was to refine the surface of the Limestone using a medium 800-grit and fine 1500-grit diamond encrusted burnishing pad which are applied with water and restore the polished appearance of the stone. The floor is rinsed with more water between the application of each pad to remove the slurry that is generated and then dried with the wet pickup machine.

I returned the following day to buff the tiles with a white polishing pad as the customer didn’t want a high shine finish which is normally achieved with the 3000-grit diamond burnishing pad, this gave a low sheen honed look as the customer had requested. The floor was then sealed with two coats of Tile Doctor Ultra-Seal which is a natural look sealer that and will protect the newly restored and polished tiles going forward.

The customer was very happy with the results and has left the following positive feedback on our website.

I gave the customer some tips on maintenance and a complimentary bottle of Tile Doctor Stone Soap to enable her to keep the floor looking its best, this product is designed for the regular cleaning of polished stone floors and is pH neutral, so it won’t prematurely degrade the sealer.

Deep Cleaning White Limestone Tiles in a Oxfordshire Kitchen

Posted on by

Photographs below of a White Limestone tiled kitchen floor at a house in Wallingford that was proving difficult for the owner to clean effectively. I went around to inspect the floor and could see that the sealer had worn off leaving the tiles vulnerable to dirt becoming ingrained in the pores of the stone. Once this happens it makes the job of keeping the floor clean quite difficult as you really need to get the dirt out of the pores of the stone to do it right and of course once you do dirt will soon become trapped again without a sealer in place.

Given these Limestone tiles were White the dirt was more visible than usual, so the customer was keen to have the floor deep cleaned to remove the ingrained dirt and then sealed to prevent the problem reoccurring.

Cleaning White Limestone Kitchen Floor Tiles

To restore the floor back to its original condition I used a set of burnishing pads which are encrusted with industrial diamonds and come in different grades from coarse to very fine. Applied with a little water the coarse 400 grit pad is designed to strip the floor of dirt and old sealers whilst the remaining pads which are a finer restore the polished surface. Between each pad you need to rinse the floor with fresh water which is removed with a wet vacuum before finally being left to dry overnight.

On this occasion I found when I started with the 400 grit pad it wasn’t having the effect I was expecting and quickly established that this floor would need grinding back with a much coarser milling pad first. Fortunately I have numerous different types of pads available and was able to switch to a 50 grit milling pad which not only got rid of any remaining seal but also grinded out the ground in dirt. This does leave the stone in a rough condition so to restore the final finish I followed up with the 400 and 800 grit pads and finished with the 1500 grit pad, rinsing with water between each pad to remove the soil that is generated. It was quote a large floor, so it took two days to complete the process over every Limestone tile.

Sealing White Limestone Kitchen Floor Tiles

To seal the floor, I used Tile Doctor Ultra Seal which works by impregnates the stone occupying its pores and thus preventing dirt from becoming ingrained in there. This particular sealer doesn’t change the appearance of the stone and so leaves it with a natural look. Again, it was a large area, so it took two days to apply two coats. I then returned on day 5 to go over the whole floor with a 3000 grit polishing pad to give the floor a slight sheen.

Dirty and Cracked Limestone Floor Tiles Cleaned and Polished

Posted on by

This customer from Louth had a very dirtyLimestone tiled floor with some cracks evident installed throughout the kitchen, hallway and conservatory. It was dull and not looking it’s best so she had asked several companies in the local area to quote but they did not feel able to help. Fortunately she discovered Tile Doctor and gave us a call, naturally this sort of work is well within our ability so not only were we able to help restore the appearance but also repair the cracks at the same time.

Burnishing Limestone Tiles

To resolve the surface cracks and remove the dirt from the floor we used a set of diamond encrusted burnishing pads which incidentally are a very environmentally friendly system which only requires water. The pads come is a setup of four and you start with the coarse pad which fitted to a buffing machine running on slow speed, the coarse pad removes old sealers and then you move onto the medium, fine and very fine pads until the Limestone is cleaned and polished again. The floor was washed down with clean water at this point to remove the soil generated by the burnishing process and left to dry overnight assisted by a turbo dryer.

The next day the floor had dried and we applied two coats of Tile Doctor Colour Grow sealer to the tiles, the sealer fills the pores of the stone making it water and resistant and will protect it from stains in the years to come, this particular sealer also lifts the natural colours in the stone.
