Mouldy Antalya Limestone Wall Tiles in Windsor Bathroom

I recently had a call out to an apartment in the town of Windsor on the river Thames, just west of London. The enquiry was to see if I could do anything with Antalya Limestone bathroom tiles that were ingrained with mould.

Antalya Limestone is a Beige/Cream stone that is quarried in Turkey, its notorious for being a soft stone that is hard to maintain and probably not the best choice for a bathroom. Reluctant to replace the bathroom tiling the landlord was looking for another option as he knew something had to be done before putting it back on the market to find a new tenant.

The homeowner had rented the property out for several years and unfortunately the most recent tenant hadn’t looked after the property particularly well. One of the problems was that the tenant had forgotten to inform the landlord that both bathroom extraction fans hadn’t been working for some time.

The apartment was located in the basement of the apartment complex, the bathrooms had no windows so without an extraction fan to remove moisture bacterial growth thrived. Having surveyed the bathroom tile I provide a quote to completely refresh the bathroom tiling which included deep cleaning and the removal of the ingrained mould.

Tile Doctor has a range of products that can be used to clean and remove ingrained soils, old sealers, grout haze and other unwanted contaminations. For bathroom tiles I use Tile Doctor Duo Clean which is designed to remove mould from tile and grout. Before starting work though I carefully removed the glass shower screens and other fittings.

To ensure the product could penetrate deep into the tiles I first had to open the pores of the stone, I did this using a soft 200 grit milling pad fitted to a handheld buffing machine. After saturating the affected areas in Tile Doctor Duo Clean and allowing it to dwell for well over an hour, we could see it starting to work. Though effective it was clear this was going to take some time to completely remove the mould, so I saturated the stone again with Tile Doctor Duo Clean and left it to work overnight. Thankfully the property was empty.

Returning the next morning the results were incredible, about 80% of the mould had been removed but I knew if we repeated the process, we could achieve an even better result. I continued with the same method as before and left it to work overnight again. Happy with results I could continue with the next stage which was closing the pours of the stone by using a set of finer burnishing pads.

The pads I use have a 6-inch diameter and fit a handheld buffer machine, they are applied to the Limestone tiles in sequence and applied with water for lubrication. The sequence runs from coarse 400 to very fine 3000 and you rinse with water to remove the soiling in between each pad.

The stone was then left to dry out before returning to seal. The sealant chosen was Tile Doctor Colour Grow which as its name suggests enhances the natural colours in the stone allowing its beauty to stand out. Two generous coats of sealer were applied allowing an hour between coats.

With the tile and grout renovated all that was left to do was to re-fit the shower controls and shower glass after giving both a clean. The client was over the moon with the result, and his concerns over having to invest in a new shower room before letting the property out were gone.

Rejuvenating a Slate Tiled Kitchen Floor in Windsor

If you’ve ever rented out a property for a long period of time, you’ll likely to have been concerned, at one point or another, about whether the tenant can be relied on to maintain the condition of carpets, walls and, of course, tiled floors.

This customer, who owns a property in Windsor (home to Windsor Castle, one of the official residences of the Royal Family) had encountered this very problem. The property had been rented out to a tenant for the last five years, but the Slate tiled floor in the kitchen, which was itself only 10 years old, had not been maintained correctly.

Consequently, the sealer on the tiles was worn out and no longer capable of protecting the stone against ingrained dirt and stains. There were also lots of efflorescent salts on the floor, predominantly contained in the high trafficked areas of the kitchen. I was contacted to correct the situation and restore the entire floor by providing a deep clean and seal.

Cleaning Dirty Slate Kitchen Tiles

To begin the restoration, I mixed a strong solution of Tile Doctor Pro Clean and water. Pro Clean is a high alkaline cleaner capable of stripping away any old sealer and eradicating any soils and grease on the floor.

The solution was spread liberally across the entire floor and left to dwell for a short period of time before being agitated and worked into the stone using a scrubbing pad fitted to a rotary machine.

This process left the stone fresh and clean, but the grout lines were still suffering from efflorescent salts. Efflorescence is the deposit of salts on the surface of porous materials such as natural stone tiles as moisture rises through the floor, causing unsightly stains. These alkali salts were neutralised by acid washing the floor using Tile Doctor Grout Clean-Up, which is a concentrated phosphoric acid cleaner.

After deep cleaning the tiles, I left the floor to dry thoroughly for 24 hours, which is usually the minimum drying period that we would suggest.

Returning to the property the next day, I ran some quick damp tests to check for any excess moisture that might have prevented me from sealing the floor. We will always do this as a precaution – especially with older floors that lack a damp proof membrane – because damp issues can damage the performance of the sealer and render it ineffectual.

Thankfully, the floor proved try and I sealed the floor with Tile Doctor Seal and Go, which is an acrylic polymer sealer that provides an aesthetically pleasing low-sheen finish, as well as, of course, strong stain and ingrained dirt protection.

As you can see from the photos above, the restoration really brought this Slate tiled floor back to life after five years of poor maintenance. The customer was very pleased to have it restored back to its optimum condition – ready for the property to be rented out again!
