Terrazzo grout line removal.
Above is an example of a floor we have recently worked on. All the grout lines were removed as they had cracked, been replaced with white epoxy or were missing altogether. We can normally cutout, epoxy fill and sand back 1000 linear mtrs of joints in two days between three operatives. All the grinding and sanding is extracted out and the epoxy we use is very low in stylene so odours are kept to a minimum.
