Fossilised Limestone Restoration – London | Blackfriars Bridge
Another specialist restoration project underway in the heart of London, just beside Blackfriars Bridge.
This fossilised limestone floor was only recently installed, but unfortunately the surface had been left with numerous dull areas, marks and staining caused by building works carried out after the floor was installed.
To make matters worse, the limestone had already been sealed, trapping dirt, marks and contamination beneath the sealant and leaving the floor looking uneven and tired.
Over the course of this week, we’ll be carrying out a full restoration process:
🔸 Remove the existing sealant to expose the true condition of the stone
🔸 Deep clean and prepare the limestone
🔸 Hone the surface using professional diamond pads to remove dull areas, marks and surface imperfections
🔸 Refine the finish to bring back the natural character of the fossilised limestone
🔸 Protect the finished floor with a breathable impregnating sealant, allowing the stone to breathe while providing long-term protection
The aim is to transform the floor from a dull, marked and uneven surface back into a clean, uniform and naturally beautiful limestone floor.
Follow along this week to see the transformation. 👀
