Terrazzo is an interesting material, originally produced in Italy, that consists mainly of concrete with segments of marble and other stone interspersed and held together with a resin. Since Terrazzo is formed in this way, I explained to the customer that I would fill the crack along the floor and the small holes around the edges with concrete, before then using tile paint to match in the colours as best as possible. This would be the most cost-effective solution, which was ideal since the customer had a limited budget for the repairs.
Before beginning the restoration, I tested a small area using a diamond encrusted burnishing pad, thereby giving the customer an indication of the type of results that could be achieved. With the customer pleased by the results, the job was booked in for the following week.
Cleaning and Burnishing a Soiled Terrazzo Tiled Hallway
To begin, Tile Doctor Remove & Go was applied to the floor and was left to dwell for ten minutes to soften the carpet glue and break down any old sealer. This was then scrubbed in to the tiles with a pad fitted to a rotary machine. To remove the remaining residue and marks in the particularly stubborn areas, I used a manual hand scraper. The entire floor was then wet vaxed to soak up the soiled cleaner and leave the area clean for burnishing. This was followed by the use of Tile Doctor diamond encrusted burnishing pads to polish the tiles, starting with a coarse grit pad, followed by wet vaxing and repeating the process with a medium grit pad and finally the fine grit pad to achieve the desired effect. I then installed a turbo dryer to dry the floor. I returned to the property once the floor was dry and carried out the repairs which had been discussed earlier with the customer (filling the holes and cracks in the floor with concrete), cleaning off any concrete residue before I finished for the day.Sealing a Terrazzo Tiled Hallway
Upon my return to the property the next day, I refined the polish on the floor even further by applying the extra fine grit burnishing pad.
To finish off the three day restoration, I sealed the Terrazzo tiles using two coats of Tile Doctor Colour Grow sealer. As an impregnating sealer, Colour Grow soaks into the pores of the stone, protecting it from ingrained dirt. Colour Grow also contains colour intensifying properties, allowing it to enhance the naturally occurring shades in the stone, and therefore stopping it from appearing dull.
This floor certainly was in a bad state, with damage as well as dirt to deal with, but I'm pleased to say that the work went a long way in transforming its appearance, leaving a very happy customer.
