Masking a Straight Line on Baseboards

What happens here

Begin by taking your painter's tape and securely tacking down the starting end onto the baseboard. Pull out about a foot to a foot and a half of tape, keeping it taut but not excessively tight. This tension allows for slight adjustments in placement. Position the tape precisely where desired, aiming for approximately a 1/16th of an inch overlap onto the baseboard itself. This slight overlap is a professional tip; it ensures that when you step back from the wall, the paint line appears perfectly straight, even if the baseboard has minor irregularities or is slightly crooked. As you proceed along the baseboard, maintain the tape's tautness and lightly press it down with your fingers. Avoid pressing too hard initially, as this would make repositioning difficult. Once a long stretch of tape is in place and correctly aligned, go back over it and firmly press it down with your fingers to ensure strong adhesion and prevent paint bleed-through. When encountering an internal or external corner, carefully bend the tape around the corner, pressing it tightly into the crease with your finger to create a sharp, clean edge.

Goal: Achieve a clean, straight paint line along baseboards
