Buying Guide

Compatibility with hull materials

Confirm the tape bonds to your hull surface—EPDM, fiberglass, aluminum, and painted surfaces require different adhesives

Waterproof and UV resistance

Choose tapes formulated for continuous water exposure and UV stability to prevent breakdown and loss of adhesion

Tape width and length

Select a width that covers seams or fasteners in one pass and a length that suits planned repairs to reduce seams

Conformability and profile filling

Flexible, micro-sealant or butyl-based tapes better conform to irregular hull contours and fill gaps

Surface prep and cure time

Account for required cleaning, priming, and recommended cure or dwell time before water exposure for a durable seal
