Buying Guide

Material compatibility

Choose tapes formulated for the substrate—look for EPDM-compatible or multi-surface sealants to ensure a chemical bond with boat hulls, decks, or rubber roofing

Adhesive system

Prefer tapes with micro-sealant or strong pressure-sensitive adhesives for flexible, long-lasting seals that resist water intrusion and remain pliable with hull movement

Width and length

Select tape widths and roll lengths that match the repair area: narrow rolls for seams and larger widths for patching or roof-length runs to reduce overlaps

UV and weather resistance

Use tapes rated for outdoor exposure—UV-stable adhesives and weather-resistant facers extend service life on boats and canoes

Surface preparation

Clean and dry surfaces thoroughly and remove contaminants; many pressure-sensitive tapes perform best when applied to clean, oil-free substrates
