* two garage floors are +20 years old concrete, 1. tractor and light garden equipment 2. truck and tools, has never been treated, Allentown, PA, probably the easiest prep, need to fill cracks in these two floors
* 2-1/2 garages are brand new concrete less than 1 year old, cars on both.
Also, do you fill the crack that is put in the concrete purposely for expansion?
OK so are you doing work in the garage or just storing the vehicles and tools there. Is this a regular thing (if you work on cars etc)... Jacks? Fluids?
