Restoring a Terrazzo hallway floor from 1924

I do enjoy breathing new life into old floors as was the case with this Terrazzo tiled hallway floor in Southbourne near Bournemouth, installed in 1924 it had been knocked about by various building alterations and then finally covered in a carpet which had been glued to the floor.

Removing Adhesive from Terrazzo tiles

Stubborn remnants of the carpet adhesive were removed using Tile Doctor NanoTech HBU Remover which is applied to the tiles and then left to soak in for a before being scrubbed in with a black buffing pad and a dilution of Tile Doctor Pro-Clean. HBU actually stands for Heavy Buid-up Remover and it’s a great problem solver that penetrates through tough stains and coatings so they can be easily removed. The floor was then washed down with clean water and any areas that needed further attention were retreated until I was satisfied with the floor was clean and free of glue.

The next step was to re-polish the Terrazzo using a set of of Tile Doctor burnishing pads which are applied in sequence from Coarse through to Super Fine with a little water to help lubricate. The coarse pad removes any surface grime and old sealant and the remaining pads build up the polish to bring back the original shine. The floor is washed down between each pad to remove the soil generated during the process.

Sealing Terrazzo Tiles

Cleaning took most of the day so I returned the next day to apply the sealer testing the floor first to ensure it was dry. To seal the floor I used a couple of coats of Tile Doctor Colour Grow which is a colour enhancing sealer that impregnates into the pores of the stone and prevents contaminates staining the floor.
The customer decided that she would conceal the concrete patches at the edges of the floor using Colours Stone Effect speckled spray paint which is available in B&Q in her own time.

Deep Cleaning and Old Terrazzo Kitchen Floor

These photographs are taken from an old Terrazzo floor in the kitchen of a house in the busy market town of Oakham, Rutland. The floor was looking rather grubby and now overdue a deep clean to remove dirt and grease from the floor and being a hard polished stone it would also need to be burnished to restore the appearance of the Terrazzo.

Stripping the Terrazzo Tiled Floor

To resolve we deep cleaned the floor by applying a strong dilution of Tile Doctor Pro-Clean which was left to soak in for a good fifteen minutes before being worked in using a rotary machine fitted with a black scrubbing pad. The cleaning solution soon became soiled as the dirt was lifted out of the floor and this was removed with a wet vacuum and the floor then rinsed with water.

The next step was to strip back the surface of the Terrazzo so it could be polished. This is done using a set of diamond encrusted burnishing pads which come in a set of four grades from Coarse to Super Fine. We started with the coarse pad which can remove dirt, sealers and other coatings before moving onto the medium, fine and super fine pads which polish the floor and bring up the surface. The pads use a little water which needs to be rinsed away after each pad followed by a thorough rinse at the end of the process.

At this stage we would normally wait for the floor to dry and then seal it using a product recommended for the particular surface, location and desired appearance however on this occasion the owner was happy to leave the floor the way it was so we were able to complete the job in a single day.
