Deep Cleaning and Sealing a Beautiful Slate Tiled Kitchen Floor in Spencer’s Wood

Slate tiles do look incredible but like any natural stone you really need to maintain the sealer if you want them to stay that way. Unfortunately it’s usually the case that the sealer wears off overtime especially in the high foot traffic areas such as Kitchens and within a few years the tiles become dull with ingrained dirt.

This process happens so gradually it goes un-noticed until the floor becomes difficult to keep clean and a decision is made to have it sorted out. This was certainly the case with this Semi Riven Multicoloured Slate tiled kitchen floor at a house in the Berkshire village of Spencer’s Wood. The floor had been installed about fifteen years prior and over the years the Slate had become soiled to the point where domestic cleaners weren’t having any effect.

To begin the restoration I soaked the tiles in a strong dilution of Tile Doctor Remove and Go and left it to dwell for about twenty minutes re-applying extra solution when it had dried. Remove and Go is our go to product for removing old coatings such as in this case sealers, although much of the old sealer had worn off it was still present in the less busy areas of the floor and to get an even final result I needed to ensure all of it was removed. Once the old sealer had started to weaken I agitated the product using a black pad fitted to a rotary buffing machine. The rotary pad struggles to reach into the recesses of the grout lines so I also made sure to scrub the solution into the grout with a grout brush.

I suspect there were multiple layers of sealer on this floor that had been applied over the years as some areas were proving particularly stubborn. Something stronger was going to be needed particularly in the grout lines. So I applied Tile Doctor HBU remover; HBU stands for Heavy Build-Up and allowed this to dwell for thirty minutes while I cleaned other areas.

Once I was satisfied that the Slate and the Grout was clean and clear of old sealers I gave the whole floor a rinse with water using a wet extraction machine. One the soiled cleaning solutions were removed you could really see the difference that the combination of cleaning products had made.

The final step in the cleaning process was to give the floor an Acid Wash using a mild solution of Grout Clean-up which removes any surface grout (aka grout smears) and other mineral deposits from the slate to ensure they true beauty of the stone will be visible. Once this was removed the whole floor was rinsed with water to remove any trace of product and then dried as much as possible. After a final inspection the floor was left overnight to dry off fully.

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 excess moisture can affect the sealer curing.

The customer was very happy with the clean and the floor was dry so we discussed sealer options to find out their preference for Matt or Satin finish. With the decision made to go with a Satin finish I began the application of the Tile Doctor Seal and Go which enhances the look of the stone with an aesthetically pleasing low-sheen finish, as well as providing on-going protection against ingrained dirt and staining.

A total of five coats of Seal and Go were needed to seal the Slate tiles and as you can see from the photos the sealer really put the life back into the floor.

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.

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!
