Defend yourself against heavy rain and moisture with Sunbrella SeaMark®. This revolutionary marine fabric features Sunbrella’s solution-dyed acrylic with a color-matched waterproof PVC backing on the underside, a combination that results in a colorfast, waterproof fabric laminate that can withstand the harshest conditions in any marine environment. SeaMark® is engineered to endure salt, moisture, sun, wind and temperature extremes. It’s UV and mildew resistant for exceptional boat exterior performance. The fabric is dielectrically sealable (also known as radio frequency welding), which is the process of welding different flexible materials together for superior seam and tensile strength.

This Sunbrella fabric is ideal for marine and outdoor awnings, biminis, dodgers, marine enclosures, boat covers and exterior marine cushions.
