Terrazzo is a combined tile made up of Marble and Limestone chippings, sometime Granite, all mixed into a clear cement resin and then made up into tiles of all sizes. We estimated these tiles we laid more than fifty years prior and were not looking their best after being stained with rust stains from heavy equipment, cooking oil and grease, ingrained dirt and grime. Although a tough job to tackle it didn't put us off and as you will see we still managed to get them clean again.
Cleaning Terrazzo Tile
The approach we used to restore the surface was to cut them back using a set of burnishing pads which take off a few millimeters off the tile surface and regrinds to make them look as good as new, this is something you can't do with Vinyl Tiles or Ceramic and Porcelain. The pads are encrusted with diamonds and are used in conjunction with a little water; you start with a coarse pad and work through the set of pads which become finer in grade as you progress until your polishing the surface. Once this process is done the floor was given a good rinse to remove any dirt and allow us to spot any areas that needed further attention.
Sealing Terrazzo Tile
When the Terrazzo tile was dry it was sealed sealing with two coats of Tile Doctor Color Grow which is an impregnating matte sealer that brings out the colors in natural stone, the client had also specified they didn't want a shiny finish as they had a concern about slippery surface that could lead to slips and falls. Once the sealer was dry it was buffed using a white buffing pad.
The results are quite satisfying given the age of the floor and the stains we had to deal with not only that but the owner had engaged a number of other cleaning companies who had tried a test clean and he had even tried cleaning it himself but the results were poor.
