The actual amount of labor hours is about 6-8 hours total. In total time from start to finish is 2 or 3 days due to dry times in between coats and letting the floor dry if you acid etch it. Grinding will save you a day or two in drying time. Once you apply the final topcoat you can put all your stuff back on the floor in about 5-6 hours and full forklift duty service in 2 days.
