I had the opportunity to use this paint a while back helping a friend paint his home. I had never used this before but had a few contractors tell me they used it and it was professional grade. They were telling the truth. It's very high quality paint and although we used a sprayer and back-rolled, it really did do a great job. We used much less paint that I thought it would take and it went on very even and looks great. Quality I won't say it's the best I've ever used but based on the results and the amount of money the paint cost, it's a great paint for the price. It's certainly better than some that are much higher priced and over hyped. Durability I'm not sure as it hasn't been up a long time. A few contractor friends tell me it's very durable so I believe them. Coverage Well, even though we were spraying, it didn't use a lot of paint so yes, the coverage is very good. Ease of Appliation The paint is very easy to roll on. I see no issues with this paint and ease of use. I recommend it.
