I have been reading and reading for weeks about epoxy floor coatings. My new pole barn is about 900 sqft and a new concrete floor. Waiting 6 weeks for the concrete to cure was the longest 6 weeks I have had in a while. One thing I have read is the coverage and some reviews seem to say they ran short. I was very apprehensive about this so I had ordered 4 3 gallon kits. 6 gallons for the first coat and 6 for the second along with 300lbs of flake. I rented a concrete grinder for a full day but finished the floor in 2 hours. When I returned the grinder my son was already mixing the color powder into the first 3 gallon kit. Followed the same procedures I have seen in 15 different YouTube videos on prep, pouring and flake tossing.The 1st coat was fantastic… the following morning when dry, it looked great. The 18” roller was HOT when I removed it from the handle from the catalytic reaction. HOT enough to drop on the ground from the high heat. It dried overnight and we Mixed the second batch for the second coat. it was better coverage and easier to go quickly. The spike shoes are absolutely necessary and the cheap ones fall off easily so put them on securely and double check them. Took an hour to re-coat…done24 hours later the floor was hard enough to to walk on and looked spectacular. I have 2 friends who saw in the next day and are ordering the mpc-100 epoxy for their buildingsIt is only a few days but this is starting out so perfectly…EDIT: it has been 19 months and actively used…. Looks as good as the day we installed it. I did drop a few heavy tools and it chipped the surface ..some as big as a quarter. Will mix a small batch and try to patch it
