This paint is difficult to apply,but it can be done! First throw out the directions or you will end up with streaks galore. YOU MUST PRIME WALL BEFORE APPLYING THIS PAINT! Base coat should be applied keeping a wet edge (again do not follow directions on can)and apply as you would any other paint. Now apply second coat after allowing first to dry overnight. Your not done, this paint requires more than two coats. Now apply third coat, and with your four inch ralph lauren roller go over any streaks that may appear, but first and this IS important roll out as much of the paint as possible from the roller and then go over your streaks. They should disappear right before your eyes and will only look better as the paint dries. Trust me this worked for me. This is a lot of work for a paint that costs this much, but it does look good when finished. Try to have the primer tinted to match the color of paint you are using, this will cut down on streaking quite a bit.
