Don’t tape. Use a square brush not an angled brush. You’ll need a bit of practise but a good clean square brush applied with light pressure to flatten the bristles, starting from top or mid point and slide along until you get to the bottom will yield a straight clean cut. Use a moisten rag to clean anything that hits the floor while it’s still wet.
