Black Limestone Flagstone floor restored in Sherbourne

This Georgian house in the beautiful historic town of Sherbourne, Dorset still had its original floor of black limestone flagstones. These were in a sorry condition, having been smoothed over with a cement screed to make it level for a carpet and, before that, painted at various times with both red and green floor paint.
A combination of cement, hardened carpet glue and old floor paints all needed to be completely removed before I could even begin to clean the original stone beneath.

Removing Sealer from Limestone Floor Tiles

After chipping away the areas of cement with a chisel I used an application of Tile Doctor Remove and Go which was left to soak into the stone for a while in order to loosen the old floor paint before steaming and wire-brushing the entire floor. This I followed with an application of Tile Doctor “Pro Clean” scrubbed in with a black buffing pad under fitted to a Numatic buffing machine to further clean the slabs.

Next step was to cut back and re-polish the Limestone flagstone using of a set of diamond encrusted burnishing pads fitted to a rotary machine. You start with a coarse pad with a little water, then a medium pad, fine pad and finish with a very fine polishing pad rinsing the floor between each pad.

Following all this treatment the flagstones needed a few days to thoroughly dry out after which I returned to seal them with Tile Doctor “Colour Grow”, a long lasting impregnating sealer which enhanced the natural colour of the tiles and turned them from a drab grey to a rich and shining black.

Sealing Limestone Floor Tiles at Canford Cliffs

Slightly unusual job this one involving a Limestone tiled floor at a house in Canford Cliffs which is a beautiful part of Dorset near Poole overlooking the sea. The tiles had only recently been laid and then sealed by a tiler, unfortunately however too much sealer had been applied and it had been allowed to dry on the surface of the tiles causing a smeared and messy appearance.

Removing Sealer from Limestone Floor Tiles

To remove the sealer from the floor the surface needs to be cut back and re-polished using of a set of diamond encrusted burnishing pads fitted to a rotary machine. You start with a coarse pad with a little water, then a medium pad, fine pad and finish with a very fine polishing pad, this takes some time but the effect it quite transforming, it does build up slurry on the floor so it all needs to be rinsed down using water and a wet vacuum to remove the liquids the wet vacuum also helps to get the floor dry.

The floor was left to fully dry overnight and I returned the next day to seal the Limestone tiles using a coat of Tile Doctor Colour Grow carefully applied using a B&Q paint pad. Colour Grow is an impregnating sealer that fills the pores in the Limestone to prevent other contaminates staining the stone; it’s also a colour enhancing sealer that lifts the natural colours in the Limestone. Once dry the floor was buffed using a Numatic buffing machine fitted with a soft white pad to give a perfect finish to the floor.

The floor is now looking as it should and the customer was delighted with the result, needless to say the tiler was very relieved.
