Creating A Beautiful Finish On A Limestone FloorCreating A Beautiful Finish On A Limestone Floor
Limestone is a beautiful flooring and comes in a variety of colours and finishes. This floor was a grey limestone that had been laid a number of years ago.
Over the years this Limestone floor hin Newcastle-under-Lyme, Staffordshire, had gradually lost its original finish and there were a number of issues that the homeowner was concerned about.
They were concerned that:
• the floor had started to lose its finish and look dull and patchy in places
• there were spots and etch marks around the worktops
• there were some deep scratches
• there was pronounced lippage – up to 3mm in places
• there were areas where the grout was coming away
• this meant it was becoming more difficult to keep clean
• the customer was also looking for an improvement in the appearance of the floor.
I suggested the customer have the floor ground smooth, then honed and polished to give it a completely new smooth honed finish that would be extremely easy to keep clean and significantly improve the appearance of the floor.
I described the change in the finish as going from a poor standard definition appearance to a high-quality high definition appearance.
On the first day, I started by installing protection to the adjoining walls, kitchen furniture and floors.
I needed to install protective film because uneven tiles can cause splits as the machine first rides over the uneven surface. This protective film protects the surfaces from any splashes caused by the restoration. As a “light tack” product it will not damage wallpaper, paint or kitchen unit finishes.
I was now ready for grinding using metal bond diamonds on our heavy-duty planetary grinding machine. This process removed all the lippage from the floor, revealing a totally new smooth surface.
This image shows the floor part way through grinding, the floor is still uneven.
The grinding leaves a rough “open” surface and the next step is to “close” the stone and make the surface smooth. This is called honing.
On day two I used the same machine to hone the floor using 50 grit, 100 grit, 200 grit, 400 grit to an 800 grit resin bond diamond disks. The floor was then lightly polished with polishing powder.
In between each stage of honing and polishing the floor was thoroughly rinsed clean with our clean and capture pressurised rinsing system to remove the slurry and any spend diamonds and polishing powder
The floor was left to dry and I applied two coats of impregnating sealer to the whole floor to help protect it against spots and spills.
To finish off I filled areas of lost grout with epoxy grout.
This grout is extremely tough and hard-wearing, so it will stay in place for the life of the floor. It can take a couple of days to fully cure, so we covered it with light tack protective film to prevent uncured epoxy being spread across the floor.
As you can see the floor now looks polished and beautiful.
Sometimes simple Limestone cleaning and sealing can turn into Limestone Grinding work, especially if the old sealer was applied over a rough, dirty surface.
