Don’t Skimp on the Brush
Buy a 2-in. or 2-1/2-in. brush, and don’t buy the cheapest option. If you take care of it and clean it well, a top-quality brush will last a long time. A cheap brush is more likely to leave brush marks and shed bristles that could get stuck in the finish. China (natural) bristle brushes are the choice for oil-based products; synthetic for water-based.

Long Strokes Create a Smooth Finish
If you can, arrange your trim boards in such a way that after you brush on the desired amount of finish, you can make your last couple strokes in one continuous pass. That will ensure no overlap marks. If you do end up with imperfections after the finish dries, sand them out when you sand before the next coat.

Oil vs. Water-Based Topcoats
Oil-based finishes are a little more durable than water-based, but the difference isn’t nearly as great as it was 10 years ago. Oil will yellow unstained wood more than water-based products will, which can be good or bad depending on the look you’re after. Yellowing isn’t an issue with stained wood. Water-based products dry faster, which helps keep dust from settling into the finish, but fast drying may be a disadvantage for slower, meticulous workers. Cleanup is easier with water-based products, and the odor isn’t nearly as strong.
