Terrazzo is a composite material consisting of marble, quartz, granite, or glass chips blended in concrete or epoxy resin. It is cured, ground and polished to smooth finish. Terrazzo flooring can be refinished repeated for a fraction of the cost of replacement. Even century-old terrazzo floors can be refinished to its original lustre with little more than minor floor repairs, refinishing and polishing.
How is Terrazzo Restored?
This is a damaged terrazzo floor in Toronto, ON repaired by The Marble Clinic. After all the areas surrounding the floor are protected, the first step to refinishing terrazzo is to remove the wax coating thoroughly with a liquid stripper and abrasive pads. The next step is to fill the chips, cracks and holes with matching coloured epoxies. Once dried, wet diamond bit grinding removes the scratches, stains, and wear pattern from the surface. Depending on the extent of the damage anywhere from 3 to 10 levels of diamond coarseness will be used.
The floor is then polished with specialized refinishing compounds to restore the terrazzo floor to its desired lustre. This is typically much brighter and clearer than the finish acquired by topical wax. The floor is then sealed to prevent staining and prolong the finish of the surface. It is recommended high traffic areas receive maintenance polishing on an annual basis to preserve the high gloss finish.
