What This Tape Is For

ScotchBlue 2090 is a medium-adhesion painters tape designed for masking and surface protection on longer projects where conventional tape would need to come off sooner. The acrylic adhesive is formulated to release cleanly without lifting paint or leaving adhesive residue for up to 14 days after application. It resists sunlight, UV exposure, and moisture, making it well suited for both indoor and outdoor work.

Compatible Applications

• Marine painting and refinishing
• Fiberglass and gelcoat surface preparation
• Interior and exterior boat and household painting
• Trim, hardware, and detail masking

Parts Desk Insights

The 18 mm (3/4 in.) width is the go-to size for detail work on boats tight curves, hardware edges, port frames, and trim lines where wider tape is harder to control. The most common issue is leaving tape on too long past the 14-day mark, especially in warm, sunny conditions, which can make removal much harder and risk lifting the underlying finish. Apply to a clean, dry surface and pull off promptly once the coating is cured.
