08019 Marine-Grade Silicone Sealant, Clear, 3 Oz

3M marine-grade silicone sealant is a one-component silicone sealant engineered to withstand harsh marine environments. Whether you're sealing a boat, protecting deck equipment, or completing home repairs in wet areas, this versatile sealant provides a reliable, flexible bond that resists mildew and maintains clarity over time. It's ideal for both professionals and DIY enthusiasts tackling above-waterline applications where weather resistance and durability are essential.

This sealant solves common sealing challenges in marine and damp environments: mildew growth that degrades traditional caulks, yellowing that mars appearance, sagging during application, and adhesion failures on challenging surfaces. The non-shrinking and non-sagging properties ensure simple, efficient application with consistent results.
