We received a call from a dentist from Edmonton who had been in his newly fitted out practice less than a year. The floor was acid stained concrete, covered with a clear epoxy coating. Unfortunately he did not like the acid stain plus the epoxy coating was beginning to delaminate in places.
After inspecting the floor it was clear the original concrete (probably power troweled) had not been ground to create a suitable surface (substrate) for the epoxy to bond to.
Due to the inevitable disruption to the business, we agreed to rectify the flooring over the Christmas/New Year vacation. The first thing we had to do was carefully protect all the rose wood cabintery with corrugated cardboard, bubble wrap, polythene, etc. Then using heavy duty industrial grinders we ground off the epoxy coating and created a profile on the surface of the concrete floor for the microtopping to bond to.
After installing the Ardex Engineered Cement SD-M Microtopping we sealed the surface with three coats of Q.C. Permaseal and three coats of floor finish.
