Sandstone Tile Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Sandstone flooring carried out in Staffordshire

Cleaning and Renovating Sandstone Floors

Sandstone is often used for Kitchen and Hallway flooring, however as with any natural stone it needs to be sealed to protect it and bring out its beauty and colouring. One of the biggest problems we find with stone flooring is with the sealer becoming stripped away prematurely by the continuous use of cleaning agents not designed for this type of surface. Without its protective sealer porous stone quickly becomes ingrained with dirt making it increasingly difficult to clean effectively.

Our method for renovating Sandstone typically involves stripping the floor of any existing sealer/coatings, deep cleaning to extract the dirt and then applying a fresh sealer for which I recommend Tile Doctor Colour Grow as it enhances the natural colours in the stone. If the floor is particularly bad, it’s best to resurface it with coarse milling pads which can remove a thin layer from the surface of the stone.

Below you will find detailed examples of work we have carried out in the past, it should give you some idea of what’s involved and what can be achieved with the right techniques and products.

Rejuvenating a Sandstone Tiled Floor at a Barn Conversion in Rugeley

The owners of this barn conversion in Rugeley had got to breaking point with their large Sandstone tiled kitchen and utility floor. They had tried various different cleaning methods without success to clean the floor, but it always appeared grimy, and they suspected it had not been sealed following installation.

This would make sense: a lack of sealer would have allowed the dirt to become ingrained in the stone, making it impossible to clean. Interestingly their next door neighbour had suffered the same problem and decided to replace the floor entirely. The property owners were seriously considering the same as a solution, that is until they as found Tile Doctor. I was called down to the property to see what could be done.

Removing Ingrained Dirt from Sandstone Tiles

To begin the cleaning process, I applied a strong, undiluted quantity of Tile Doctor Pro Clean to the floor and left it to dwell for a few minutes. This allows the high alkaline cleaner to seep into the pores of the stone to begin to break down the ingrained dirt. After the short dwelling period, I scrubbed the floor using a rotary machine with a black pad attached.

With the tiles clean, I then focused specifically on cleaning the grout lines and edges of the floor using a grout brush in combination with a steamer. Finally, I rinsed the floor with cold water, before vacuuming up the resulting cleaning slurry before leaving the tiles to dry completely overnight. The drying period is exceptionally important because excess moisture can cloud any new sealers and damage their performance.

Sealing Sandstone Tiles

I returned to the property the next day to find the clean tiles showing some signs of damp. It’s possible that the property, being a barn conversion, does not have a damp proof membrane installed beneath the floor, making these sorts of issues inevitable.

To be on the safe side, I opted to seal the Sandstone tiles with Tile Doctor Seal and Go Extra, which allows full moisture vapour transmission, making it fully breathable and ideal for these situations. It also provides durable protection against ingrained dirt and stains and does a good job enhancing the look of the tiles.

The customers were very happy with the result, and left the comment below on the Tile Doctor Feedback system.

WONDERFUL, delight to have Trevor restoring my very tired flagstone kitchen floor, it is now beautiful. Many thanks Trevor a job very well done.

I’m sure they were also relieved that they won’t have to go to the expense of replacing their fantastic Sandstone tiled floor. What was Once a problem is now a real asset to the property.
