My Baseboard Painting Experience
Prior to installation, I painted my primed pine baseboards with BM Regal Semi-Gloss. As an experiment, I used a brush for half of the baseboards and a roller for the other half. The roller was 4" long with a 3/8" nap and made of microfiber.
Applying the paint with a brush was more time-consuming than using a roller, and I was surprised that the results were better with the roller. The brushed baseboards show minor brush marks (as expected) which are only noticeable upon close inspection. The rolled baseboards have a very slight 'orange-peel' look, again only noticeable if one is looking closely.
I did not expect the results from the roller to be as good as they are. This is my first time using a microfiber roller which may have made the difference. In the future, I will use the roller method. The only downside I foresee is that post-installation touch-ups will need to be done with a roller.
