Do it every day.

Thanks. I didn't know how much it was done, or how effective.

Roll on + brush out is the only way to efficiently paint trim (except spraying!) Brush alone does not get the paint on fast enough, or as evenly as possible with the roller.

Yea, if you are really looking for perfect trim, hire a painter that will spray. Unless you are looking for that 'brush mark' look, then rolling first and backbrushing the paint is the best way to paint trim if you are doing it by hand. Do not think that they are actually rolling the paint on and then brushing it later...they do it immediately after applying the paint with the roller and work in small sections. Think of the roller in this case as a mechanism to simply get the paint on faster.

Thanks, this is so helpful. I want it to look like it was put on with a brush, but I don't need to see a lot of brushmarks. I just don't want it to look like orange peel. It sounds like using the roller to get it on to the surface followed by immediately brushing would be fine.
