What This Tape Is For
ScotchBlue 2090 is a medium-adhesion painter’s 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
- Woodwork and cabinetry
- Glass and metal surfaces

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.
