Is there an avg. cost per square foot? Our garage is about 1000 sq. ft. with concrete floors.
Also, what sort of prep work would we need to do?
Every area is different. In northeast PA, cost may run about $5 a square foot. Prices fluctuate, depending on design, product type, condition of floor. Best prep method would be to grind the floor and repair any cracks.
If your slab is suffering from low self-esteem because of pits, craters or cracks, you can cover up those scars. Concrete “resurfacer” is a cement-based coating that forms a smooth, new surface right over the old concrete. The cost of resurfacer for a two-car garage is typically less than $2000.
