The surface should be clean, dry and dust-free so the tape sticks properly. Lay tape onto the surface, pressing down as you go. Dont stretch the tape, or it may lift or break. Press tape down firmly with a smooth edge, like a putty knife or credit card. Wait about 30 to 60 minutes before you begin painting. Wait until the paint is dry to the touch before removing the tape. Cheque the paint can for the manufacturer's dry times. Use a putty knife or razor blade to score along the edge of the tape. This prevents paint from being pulled up with the tape and from cracking along the paint line. Taking your time, lift up the painters tape and pull it back on itself, removing at a 45 degree angle. If adhesive sticks to the surface, try a 90-degree angle. Youll get a sharp, clean line and a professional looking paint job!
