I have a detached garage that I am insulating and heating the concrete floor is in need of repair it is chiped and pitted the areas that need repair are all different sizes, most of it is under 2". There is some rusted steel that is exposed in the damaged areas. What is the cheepest esyest way to repair? I dont care what it looks like or how perfict it will be this is going to be a workshop and I just dont want to trip and break my neck. I have tried some quikcrete vinyl patch in the 40pd bag and it worked great however it is $$$$!!! and I have a lot of area to cover.
