Product works a described! Used in a pole barn with a machined troweled finish, it went alot further than I expected. I bought 3 5gallon pales for 1728 sqft which was about right for 2 coats based on their coverage estimate. I ended up being able to put 4 coats on. Would have been fine with buying 2 5 gallon pales. I didnt etch my concrete either and it still absorbed very well. Water beads very well on it. Smell is strong and took a couple weeks to completely go away. Works great so far.
