We took this project with the intention to replace and old Microcement with a new one. The existing floor was cracking and showing broken areas, so we stated to grind the floor up to the bare concrete where we found specific spots of humidity caused by metal pipes inside the concrete that where rusted and condensating the humidity. Suddenly the project changed to a bigger demolition of the floor to remove all the metals pieces without compromising the structure of the floor. Humidity from below is the worst enemy of any resurface, as it deteriorates the floor causing cracks and even de lamination. Once solved the problem, we applied a Vapor Barrier to protect the new application and proceed with our system of multiple coats of base surface, top coats and a sealer system.
