A few months ago I was called down to the coastal town of Southend to restore a damaged Terrazzo tiled floor. Terrazzo is a very beautiful type of stone of Italian origin, and has been used for hundreds of years for residential flooring. The problem with this floor was a significant crack in the surface that was not only spoiling the appearance of the Terrazzo, but also posed a potential hazard for anyone walking in and around this area. I was also commissioned to give the floor a thorough clean and seal .
Repairing a crack in a Terrazzo flooring
To begin the repair, I first mixed a strong solution of one part Tile Doctor Pro-Clean to three parts clean water. I then applied this solution to the hole and the surrounding area, making sure that any dirt and muck had been completely removed before filling. Pro-Clean is a versatile, alkaline cleaner recommended for cleaning natural stone floors.
The damaged area was then dried using an air blower to remove any moisture from in and around the hole, paying special attention to the tricky cracks that were not so easy to dry. The cracks were then filled with a stone glue and hardener. Once the filling had been completed I gave the area a coat of acrylic paint mixed with glue to match the original colour of the floor as much as possible. The final stage in the repair process was sanding down the treated area to achieve a smooth surface that was consistent with the rest of the floor. As you can see from the photograph, the finish came out very nicely however I apologise for the photograph which I appreciate could have been better.
Cleaning a Terrazzo tiled floor
As aforementioned, I was also commissioned to give the floor a thorough clean. I did this using a similarly diluted solution of Pro-Clean and water. The solution was worked into the stone using a black scrubbing pad fitted to a rotary floor scrubbing machine. After completing the clean I rinsed the floor and removed the resulting soil with a wet vacuum, I then left the property to allow the floor plenty of time to dry before being sealed.
Sealing a Terrazzo tiled floor
I returned the next day to seal the floor using Tile Doctor Shine Powder. The crystallised powder is applied directly to the floor and then worked in with a buffing pad. The result is a nice durable shine which had previously become dull over time due to high usage and the breakdown of an old surface seal.
