Restoring an old Terrazzo floor

I previously restored an Quarry Tiled floor for the owner of this residence near Caerphilly Castle and was asked back to deep clean their Terrazzo hallway floor which was far from looking its best.

Restoring a Terrazzo Floor

Terrazzo is a very hard surface and needs to be burnished to get the best results so after scrubbing the floor with Tile Doctor Pro-Clean and a black scrubbing pad to remove what felt like 100 plus years of black dirt I set about burnishing the floor with a set of diamond encrusted burnishing pads and a little water. The set comprises of four different grades of diamond pads ranging from coarse to smooth that produce a shiny clean surface. The floor is rinsed between pads to remove any slurry from the process and given another rinse at the end.

The hard Terrazzo soon dried and I was able to seal the floor with the application of three coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer which will prevent staining and make it easier to clean in future. Once the last coat was dry I and gave the floor a further polish with the 4th stage green pad to give a true deep shine.

I think you will agree that what was once an old and tired terrazzo hallway floor now looks much better following its facelift, something that was only made possible due the quality of installation when first laid.

Deep Cleaning Terrazzo Floor

Just to prove we take on any job large or small I thought I would post the details of this small Terrazzo Vestibule that we recently cleaned at the entrance to a house in Glasgow. The Terrazzo was not looking its best which is hardly surprising being in front of the main entrance to the house it must have seen a lot of foot traffic over the years.

Cleaning and Burnishing a Terrazzo Floor

Terrazzo is a very hard surface and as a result it has to be treated in the same way as other hard surfaces such as Travertine, Limestone and Marble which typically involve burnishing the surface to remove the dirt and restore the appearance.

Before burnishing the floor was cleaned using a strong dilution of Tile Doctor Pro-Clean which was left to dwell on the Terrazzo for a while before being scrubbed in by hand due to it being such a small area; following that the floor was given a quick rinse with water and a quick clean with Tile Doctor Neutral Cleaner to remove any trace of strong cleaning product.

The next step was to burnish the floor using a set of four diamond encrusted burnishing pads. You start with a coarse 400 grit burnishing pad which is run over the surface with a little water to help lubricate and this removes surface dirt and coatings such as sealers. Once that was finished we moved onto the medium 800 grit pad which is the first step of the polishing process and also removes ingrained dirt. The surface of the Terrazzo is still quite rough at this stage so once complete with the medium pad the fine (1,500 grit) is used smooth down the surface and continue to build up the polish in the floor. The last pad is a very fine (3,000 grit pad) and this pad builds on the existing polished effect to create a high shine finish.

All these pads are applied with water and the resultant slurry needs to be cleaned off during the process with the final step of giving the floor a thorough rinse with clean water.

Sealing a Terrazzo Floor

Once the floor was completely dry it was sealed using two coats of Tile Doctor Colour Grow which is an impregnating sealer designed to bring out the natural colours in the stone and penetrate into the pores of the tile preventing dirt from getting in there and providing maximum on-going stain protection. The floor was then buffed using a white buffing pad to bring up the shine further and remove any smears left from sealing.
