Overlays are a great option on concrete in good condition or for locations where tearing out is just not feasible. Overlays are a polymer based high grade concrete applied at 1/4"-1/2" thickness used for interior and exterior applications. Since they are not applied at the traditional 4"-8" thickness, one main advantage is it does not affect height noticeably which is key when doorway clearance or height is a concern. With any resurfacing method the preparation of existing concrete or surface is the most important step to allow new material to adhere. We start by grinding or clean surface and go as far as changing chemical PH of old concrete. There are many texture options depending on application like spray texture commonly used on vertical surface, smooth troweled for interior and even able to stamp existing concrete.
