Terrazzo is a man-made flooring material made of marble or granite. This is set in concrete and polished to achieve that smooth surface, then sealed for protection. Terrazzo is a durable flooring material that is easy to maintain, but over time, you may need a terrazzo floor repair expert to patch up some damage and to restore its surface finish.
Restoration of terrazzo flooring may be a job that requires professional technicians and special procedures, but there are things that you might be able to do on your own.
Your old terrazzo floors may be discolored, or their surfaces may have been damaged because of the build-up of soap scum, use of disinfectants, or because of dirt and grit which have accumulated on the floor. On your own, you may be able to strip your terrazzo floor to its original surface, clean it, and then seal it.
- The first thing you do is to select the appropriate terrazzo floor restoration products that you have to use. Always wear protective gears and work in well-ventilated areas when handling chemicals. You may need to cover adjacent areas to protect them from the chemicals before you start stripping the existing sealers and coatings from your terrazzo floor.
- Be sure that you have a neutral terrazzo floor cleaning liquid that is specifically formulated for your type of terrazzo floor. Follow the manufacturer’s directions, apply the cleaner to the floor and let it stand for the recommended time. Apply water, just a mist, over the cleaner on the floor, and pick up the residue with a wet vacuum.
- Now comes the hard part. Use a power scrubber with a scrub brush attachment, and scrub the terrazzo floor until the coating materials are removed. Pick up all residues with a wet vacuum, and thoroughly rinse the surface with clean water. Vacuum all remaining liquid and allow the floor to dry. Remember not to use steel wool or metal brushes when you scrub the surface of your terrazzo floor. If necessary, you can repeat the process.
- After stripping your terrazzo to its original surface, you can clean it with a mildly abrasive phosphate-free cleaning compound. Be sure it does not contain harsh fillers but formulated to restore and clean your terrazzo.
- Your next step is to apply the new sealer. Use a colorless, stain and slip resistant sealer. It must have a pH factor between 7 and 10 so as not to affect the color or the physical properties of your terrazzo floors.
There you have it, you have stripped your terrazzo floor, cleaned it, and sealed it. It must be looking good now. But when it has reached the point that the scratches, or the dirt, or the build-up of coatings are so severe, and no amount of stripping, cleaning, sealing can restore the floor, then it must be time to strip the floor using resurfacing screens or fine grit stones. This involves grinding off a thin layer of the terrazzo which must be used only as an extreme measure. It is best to leave this job in the hands of experienced Terrazzo floor repair professionals. Grinding and polishing the terrazzo floor removes deep scratches and stubborn stains, it also produces a smooth, clean, and uniform finish.Find me on Google+
