Making Sense of Sunbrella® Marine Fabrics

Item # X-HT-300034

Sunbrella® offers several great lines of marine fabrics in a variety of colors. We love these products and their color lines, but with so many to choose from, it can be hard to know if you’ve ordered the best one for your application. Each of Sunbrella’s lines has its own unique properties that make it perfectly suited to different projects. We’re going to break down the differences between all these marine solids, so you can rest assured you’re making the best choice for your next project.

Sunbrella Marine Grade

Sunbrella Marine Grade is the standard cover cloth of the marine industry. Like all Sunbrella fabrics, it is a 100% solution-dyed acrylic fabric and is soft, breathable and UV, water and mildew resistant. Sunbrella Marine Grade will not noticeably shrink or stretch and both sides of this fabric are the same, so either side can face out. Sunbrella Marine Grade is suitable for use in awnings, dodgers, biminis, sun bands, boat tops, sail covers, outdoor covers, outdoor furniture, cockpit cushions and enclosure curtains. Marine Grade fabrics are 46” wide, but select colors also come in 60” width. These fabrics are exactly the same, just wider.

Sunbrella SeaMark®

Sunbrella SeaMark 60” fabric is completely waterproof. This performance solution-dyed acrylic has a color-matched PVC backing on the underside, resulting in a fade resistant, waterproof laminate that can withstand extreme conditions. SeaMark successfully combines the look of canvas and excellent colorfastness to create one long-lasting marine fabric. To add visual interest, there are two SeaMark products that feature a different color on the underside. Choose Sunbrella SeaMark for marine tops, waterproof seating, marine covers, tonneaus and awnings. When working with this fabric, the PVC backing on the underside should always face inward and the acrylic side should face outward.

Sunbrella has a lot of great acrylic fabrics to offer and hopefully now the choice between them will be a little less daunting.
