Stone and Tiled floors will degrade over time so much that they can appear to be simply beyond being restoration. It goes without saying that years of neglect will do this to any surface but it’s worth knowing that the appearance of Tile and Stone can be extended when treated to routine maintenance using the right products and methods.
I’m sure many other tile cleaning companies had passed up on the opportunity to restore this Slate Flagstone tiles at a cottage in Hawkshead, simply because they did not feel they had the resources to make a good job of it. The tiles were in such a rough state that the property owner felt like there might be no alternative other than to rip them up and replace them.
However, while the floor was certainly past its best, it remained secure. Some areas had been concreted to reinforce them, but the floor was mainly suffering from an aesthetic problem, rather than a structural one.
We knew that a general clean and seal job would not do the trick, but Tile Doctor have developed a system to successfully salvage tiles in these situations. It is called ‘Milling’ – here’s how it works.
Milling a Slate Flagstone Tiled Floor
Milling is a process which uses very coarse diamond encrusted pads to remove the old, damaged surface layer of stone to re-face the stone with a new, smoother surface.
This not only makes the floor look completely like new; it also makes it much easier to start cleaning regularly again to maintain its appearance for the long-term. Additionally, it means that we can successfully seal the stone to protect it against ingrained dirt and staining.
Once we had completed the milling process the stone and grout was given a thorough scrub with a dilution of Tile Doctor Pro-Clean agitated with a black scrubbing pad fitted to a rotary machine. This was needed to remove the soil generated by the milling process and also to ensure the grout was clean. Once done the soil was rinsed away with water and this was then removed using a wet vacuum.
It had become apparent during the milling process that much of the grout had also failed so the next step was to rake out the grout and replaced with a flexible floor grout and the floor left to dry out completely.
Sealing a Slate Flagstone Tiled Floor
Since there was no damp-proof membrane present (due to the floor being very old), we sealed the tiles using Tile Doctor Colour Grow, an impregnating sealer that allows for moisture vapour transmission and therefore helps to eliminate damp issues.
Colour Grow is also a colour intensifying sealer, so it really helped to elucidate the natural dark shades in the Slate. The outcome of the restoration is pictured below.
The customer was absolutely amazed by the transformation and left the feedback below on the Tile Doctor feedback system.
“We found old flagstones under the carpet which were in need of cleaning. Russell came out to view work and he recommended painting areas of cement with grout paint to match flagstones. Pleased with the work carried out and help and information received from himself and Heidi.”
It can be hard to believe that floors which appear so far beyond salvation can be saved but this example goes to show that anything is possible with the right knowledge and techniques!
