Professional Terrazzo Restoration Services
PREPARING FOR TERRAZZO RESTORATION
Generally the first step in terrazzo restoration is to remove any old flooring that might be present or wax. Our technicians will then identify any areas of the terrazzo that will need to be repaired. The technicians will then address those areas by patching the divots. As well as make an attempt to color match any new stones that are placed.
Next we will use diamond impregnated pads to grind off the top layer of the terrazzo floor, usually only a few millimeters. We do this to help create a more uniformed surface in preparation for polishing. The next step is to diamond polish the terrazzo. Using consecutive grits, of resin-bonded diamond pads, especially made for terrazzo.
This process will be repeated 6 to 8 times to help achieve the desired shine. During the whole diamond grinding and polishing process we will use water as a medium to cool the pads and to capture any residue from the terrazzo. This technique allows the process to be mostly dustless, it is also more environmentally friendly than other techniques.
WAXING & POLISHING
We can offer a variety of options when it comes to how glossy you want the floor to appear. We can stop polishing at a lower grit if you want a more matte appearance. If you want the floors to have a more glossy look we can implement higher grit pads. We also offer a couple different sealers based on the traffic that the floors will receive. If the floor is in a commercial building we may offer a different sealant that can offer more protection to a high traffic area.
CLEANING & SEALING
Once the terrazzo polishing process is completed we will clean up the floors in preparation of applying the sealant/finish. We will remove the slurry, then use a hospital grade disinfectant, to kill any microbes. We will the apply a neutralizer to the floor to make the surface as pH neutral as possible. We will then apply multiple coats of a sealer that bonds to the surface of the terrazzo. Our sealer is a high solids metal interlock product. The sealer that we use is not a polystyrene based (plastic based) wax product. It will help create a very durable surface that will be resistant to stains, impacts, and other hazards of everyday life. Dr. Terrazzo has used this product for many years to seal many miles of terrazzo.
