I have worked with the Suede finish now for over a year on different rooms in my house using the color Spitfire. The xxx's are a problem but there are a couple different ways to minimize the overlapping lines. Working in sections from the ceiling down is an ABSOLUTE "NO NO". Reason being that when you're making your xxx's you are bringing the brush strokes downward; when you begin your next row, and you overlap, you'll get visable lines.
On my basement, I used a darker color Silver Blaze. After rolling the first coat on (and I do agree the foam rollers fall apart you just have to keep throwing them out and using a new one) I then made my xxx's horizontally and just flew...I mean you have to work at lightning speed to keep the paint from drying and getting lines.
I am now taking on my biggest challenge, which is a wall I haven't painted yet from earlier using the Spitfire. This wall is 16 feet tall and about 20 feet wide. I am not going to be able to go lightning speed because I have to keep getting down off the ladder. What I think I'm going to try (because the xxx's are DEFINATELY the way to go if you do it correctly) is after each small section with a partially dry brush is feather out the bottoms of my brush strokes to make them thin. This way, when I start the second row the paint won't be so thick if it overlaps.
