3M 7100185142 Blue Painters Tape 3 in 180 Ft Paint Masking

Product Description

The 3M 7100185142 is a blue painter's tape designed for clean paint masking on a wide range of interior and exterior surfaces. Part of the 3M 2090 Series, this tape measures 3 inches wide and 180 feet long with a 5.3 mil thick paper backing. It delivers 27 pounds per inch tensile strength, giving it the rigidity needed to apply cleanly and tear evenly by hand. Licensed painters, finish carpenters, and general contractors use this tape to create sharp paint lines without surface damage. It removes cleanly after up to 14 days of sunlight exposure, making it reliable for both short-duration touch-up work and multi-day paint projects.

This tape is suited for residential and light commercial painting applications. It adheres to glass, metal, previously painted surfaces, trim, and woodwork without lifting or leaving adhesive residue when removed within the recommended time window. At 3 inches wide, it provides broad coverage for masking door and window trim, baseboards, and adjacent surfaces during spray or brush application. It is commonly stocked by painting contractors and remodeling crews as a standard masking consumable.

Do not leave tape exposed beyond the rated sunlight exposure period, particularly on heat-absorbing dark surfaces.
