3M 7100187348 Masking Tape 38mm 60yd 5.7mil Blue

Product Description

The 3M 7100187348 is a blue paper masking tape designed for paint masking applications across a wide range of surfaces. It measures 38 mm (approximately 1.5 inches) wide and 60 yards long, with a 5.7 mil thickness that provides consistent conformability around edges and contours. The tape delivers 27 lb/in tensile strength, resisting tearing during application and removal. It is suited for use by painters, contractors, and trade professionals who need a reliable masking solution on glass, metal, painted surfaces, trim, and woodwork. The tape removes cleanly after up to 14 days of sunlight exposure, reducing the risk of adhesive residue left on finished surfaces.

This tape is used in residential and commercial paint masking work where clean, sharp lines are required. Typical applications include masking off trim, window frames, metal fixtures, and previously painted surfaces before spraying or rolling new coatings. It is part of the 3M 2090 series and is appropriate for both interior and exterior masking tasks where moderate UV exposure is expected. Painters, finish carpenters, and auto refinishing techs commonly reach for this tape when working around glass and woodwork details that require clean adhesive release.

Compatibility

Suitable for use on glass, metal, painted surfaces, trim, and woodwork. Intended for paint masking applications where clean removal within 14 days of sunlight exposure is required.

Installation Notes

Applied by hand or with a tape dispenser; no special tools required. Ensure the substrate is clean, dry, and free of dust or oils before applying tape for best adhesion and clean lines. Remove tape at a low angle while the coating is still slightly flexible to minimize edge lifting or paint pulling. Do not leave tape applied beyond the rated 14-day UV exposure window to avoid adhesive transfer.
