Sandstone/Portland stone staircase restoration

Stone Rescue provides expert natural stone repair and restoration services, not only for floors, walls, worktops, showers and other “regular” jobs.

Our team have the knowledge, experience, and expertise to handle unusual, delicate or even difficult restoration projects.

Over the past 15 years, the Stone Rescue team has done countless staircase restorations. The projects have ranged in style, size, and stone type. 

Our most recent interior restoration project carried out by our team, was in Nothing Hill area, restoring the Sandstone/Portland stone staircase including turning landing of a Grade II listed building. (Grade II listed buildings are subject to regulations which protect their historical and architectural significance.)

Sandstone/Portland stone is a long-lasting and versatile stone that is applicable for exterior and interior projects too.

By nature, Sandstone/Portland stone is made up of fine grains of minerals like quartz or feldspar combined in a pattern of calcite.

We removed 3-4 layers of paint from the stone, by grinding and polishing the stone surface.

Most of the job, the grinding and polishing has been dry executed.

Many processes in the stone restoration industry, from grinding, polishing to cutting create large quantities of dust. The dust released during manual polishing can have a high quartz content and therefore pose a serious health risk, also the air movement generated by the rotating grinder pushes the dust in all directions.

Therefore, we have an advantage in technology in capturing and collecting the dust.

To remove the paint, we’ve used a titanium-based metal disc. Titanium is a perfect material for the job due to its character in working well on high temperatures and less clogged with paint or glue.


There are endless ways to finish the stone by giving it different textures from honed, polished and flamed to tumbled, satin, river or leather finish. This can be achieved using a variety of different methods in conjunction with tools, machineries and chemicals for the desired end result.

The stone has been polished to matte shine and a non-slip finish in order to pass the industry’s standard (applicable to public buildings).

Part of the restoration process, the staircase steps have been treated with an impregnator water-based sealant in order to gain water resistance, which can ultimately make a big difference when it comes to protecting the stone.
