Nope....do it undiluted!!! It is a bit more work since it's more like roof tar than paint but it works much better this way. I did two coats on the walls and three coats on the ceiling (but that was due to the ceiling having a matte paint and the first coat got soaked up. Use good thick (10mm or so) microfiber rollers. No need to roll out too much on the paint pan since you want a thick coat and roll it slowly out. It was quite a work out. Test it out on small patch and you will how it gets applied...it is not like any other paint you have ever used before. This stuff is REALLY thick!Wow, yeah... that is easily the nicest looking painted theater I've seen. Rosco Supersaturated Black you say? I'm looking at this and its saying mix 1:1 with water, although I'm also seeing dilution will cause a glaze effect? Any tips on how you achieved that? I think I'm going to give it a try. Thank you so much!
