3M 7000049309 Outdoor Masking Poly Tape 5903 Red 48mm X 54.8m

Product Description

The 3M 7000049309 is a heavy-duty outdoor masking poly tape built on a conformable polyethylene film backing with a synthetic rubber adhesive. Sold as the 3M Tape 5903 in red, this tape is engineered for masking applications that require exposure to outdoor conditions. The 7.5 mil thickness gives it durability against tearing during application, and the UV-resistant construction allows it to remain in place for up to 30 days without deteriorating or fading. Adhesive residue is minimal on most opaque surfaces after removal. Tensile strength is rated at 21 pounds per inch of width, making it suitable for demanding masking tasks on jobsites and in production environments.

This tape is used in residential and commercial applications where an outdoor masking solution is needed during painting, coating, or surface protection projects. The conformable backing allows it to follow contours and irregular surfaces, and the film can be torn by hand without a dispenser. It is commonly applied by painters, contractors, and finishing professionals working in exterior environments or shops with exposure to UV and weather during cure or hold periods. The 48mm width and 54.8-meter roll length are standard sizes for production and spray masking work.

Key Features

• Heavy-duty 7.5 mil polyethylene film backing resists tears during masking and removal
• UV and weather resistant for outdoor use up to 30 days
• Removes cleanly with little or no adhesive residue on most opaque surfaces
• Tears easily by hand without a dispenser
• Conformable backing follows curved and irregular surfaces
• Tensile strength of 21 pounds per inch of width for reliable hold under stress

Compatibility

Designed for use on most opaque surfaces as an outdoor masking tape for painting, coating, and surface protection applications requiring up to 30 days of UV-resistant hold.

Installation Notes

Surface should be clean, dry, and free of dust or oils before application to ensure proper adhesion. Apply with firm, even pressure across the full width of the tape to prevent lifting at edges. Remove tape within the rated 30-day window to achieve clean removal with minimal residue. Do not use on surfaces where adhesive residue tolerance or maximum temperature above 173 degrees F is a concern.
