REHAB

perhaps a little late, but contact MAPEI for products and education along the line you want to know. though mainly a tile supplies support company, they also have specialized concrete products and courses that will help you become a better informed and technical tradesman. You may also look into a scarifier (floor grinding machine with heads wet or dry). While World of Concrete is past until January, look up their website for product overviews and details. perhaps plan to visit the next one.
