Put the tape down. Go ahead. Now imagine skipping it entirely and still getting a clean corner. That is what an angled brush does.

I painted my hallway last month and did not use a single strip of tape. The corners look like a pro did them, and I saved an evening of peeling and swearing.

Why angled brushes win

A 2 inch angled brush has bristles cut at an angle, which lets the tip ride the corner while the handle stays out of the way. You get a precise line without masking. Tape is for people who do not trust their hands yet.

The technique

1. Load the brush lightly. Dip about a third of the bristles.
2. Start an inch away from the corner and brush toward it.
3. Use the tip to feather the paint right into the corner line.
4. Keep a wet edge and work in one direction.

The mistakes that ruin corners

Overloading the brush makes paint bleed under the line. Pressing hard splays the bristles and the line wobbles. And painting a corner with a roller first leaves a fat ridge you then have to chase. Cut in the corners first, then roll the flats.

Do not fight the paint

Use the paint at the right consistency. If it is too thick it drags, too thin it drips. Stir it well before you start. And clean the brush the same day, dried latex paint ruins a good angled brush fast.

When tape still earns its keep

Against glass, trim, or a ceiling with texture, tape is still the smarter tool. But for plain walls meeting at a corner, the angled brush is faster and leaves nothing to peel. My hallway took two hours instead of four.
