just put on a first coat of this stuff. it's different, that's for sure. of course, the videos make it look super simple.
it's not terribly expensive by the gallon but it goes on a bunch thicker than normal paint. their website says 2 gallons will cover 50 sq ft with 2 coats. the packaging on the box says 2 gallons covers 100 sq ft, 2 coats. i think it's somewhere in the middle. i used 2.5 gallons on about 225 sq ft but i didn't go as thick as the instructions. the roller that's included in a 2 gallon kit lays it on really thick. they say you can roll and tip the 2nd coat but i tipped the first. it filled in cracks and screw holes better that way plus spread a little further.
