Professional-grade crepe-backed masking tape with rubber adhesive for paint masking, bake operations up to 250°F, and industrial holding applications. Strong, tear-resistant, and removes cleanly without residue.
3M™ General Purpose Masking Tape 234 is a versatile, crepe-backed masking tape engineered for exceptional performance in both general painting and paint bake operations. This professional-grade tape features a strong rubber adhesive that provides instant adhesion while maintaining the ability to remove cleanly without damaging surfaces or leaving residue. The crepe paper backing is specially treated with heat and solvent-resistant saturant, making it ideal for demanding industrial applications including window and door manufacturing, automotive painting, and general indoor use.
The tape performs reliably at temperatures up to 250°F (121°C) for up to 30 minutes, making it suitable for medium-temperature paint bake operations. Its controlled unwind mechanism ensures even dispensing from the roll, reducing premature tearing and waste. With a tensile strength of 480 oz/in (52.5 N/100mm) and 10% elongation at break, this tape offers excellent holding power for masking, protecting, bundling, and light-to-medium duty attachment applications. The one-piece removal design and sliver-resistant properties ensure professional results every time.
Manufactured without solvents for reduced environmental impact, this tape is certified to ASTM D-6123 standards. Each case contains 72 rolls of 12mm width × 55 meters length, providing excellent value for high-volume industrial operations. The tan color provides good visibility during application and removal, and the tape bonds exceptionally well to paper, metal, wood, and painted surfaces, making it one of 3M's most popular general-purpose masking solutions.
