My colleague Nick Thompson of Premfloor had a contract to restore a Terrazzo Toilet area in an old Nat West Bank Listed building in Wandsworth.
Premfloor asked for my help as they had a lot of projects on the go at the time.
The Terrazzo floor was stunning but was now overdue for some love and care to restore it back to its’ former glory.
The room looks great, thank you for your hard work.
Restore Terrazzo Walls And Floors
We used metal diamond tooling to remove the old, stained Terrazzo from the walls and floors.
This was quite a lengthy process as we had to use hand equipment on the walls.
The grinding process generates a lot of dust. So we used high-quality dust management equipment.
Terrazzo Hole Repair
We removed lots of old wall plugs. Also, window security bars had been cut off at the wall, so we hammered the remaining parts of the bars into the wall.
We cleaned the holes and filled them with colour matched Terrazzo.
Finally, we smoothed the repairs to the surface of the wall.
Terrazzo Crack Repairs
The Terrazzo walls had vertical expansion joints to help minimise cracking. However, there were lots of cracks on the walls, which is not surprising, considering its age.
We cleaned the larger cracks on the walls and floors to prepare them for filling. Then, we filled the cracks with colour-matched cement grout and left the grout overnight to dry. When the repairs had dried, we sanded the repairs smooth.
Terrazzo Floor Repair
There were three cracked Terrazzo access panels in the floor, covering an old services channel. We were asked to completely fill the channel, as it was no longer needed.
We removed all old access panels and associated metal works. Then filled the channel with concrete to 15mm below the floor level.
When the concrete had cured, we filled the repair with colour-matched yellow Terrazzo.
Once the Terrazzo had cured, we honed and polished the repair and the floor to a low-sheen finish.
Finally, we applied a high-quality Terrazzo sealer to help protect the new finish.
Terrazzo Cleaning Advice
We gave the client cleaning instructions to help prolong the finish. It is important to use specialist Terrazzo cleaners because the standard floor and wall cleaners will degrade the sealer and make the Portland Cement porous.
