This was a 9,000m2 project in which we refurbished over 3,500LM of joints, hundreds of tiles, joints along expansion strips and around several floor boxes. The joint colour was standard white, and was removed using a combination of hand polishers and floor machines.
Newly refurbished joints will stand out due to their matt appearance. Since the entire floor was to be diamond polished afterwards, then these repairs will be automatically blended in. If not, each is to be treated by localised diamond polishing to speed up the blending in process.
We opted for a 3 phase floor grinders to polish the terrazzo and blend in all repairs. This was done using minimal water and completed over a period of several weeks. Battery-powered wet vacs were on hand to remove the resultant light slurry. A case hardener/densifier was then applied to fill any micro pores revealed during the grinding and polishing process. A final buffing up provided the full shine.
