Practical Sailor checked out a selection of coatings for inflatable fabrics to see which one would best stand up to the tests of time on the water—and under the sun. This review of their application, abrasion resistance, and adhesion is the first report in the long-term test of these coatings.

“Best Choice for Hypalon is the Polymarine Flexithane. It’s pricey, but it was a top performer in this round of tests.”

“The Best Choice for PVC is Polymarine’s other coating, Superflex.”The Superflex is priced at the high end of the spectrum, but its cost is somewhat more palatable given its top performance.”

To determine the paints’ abrasion resistance, testers dragged a 320-grit sanding block across each panel three times. Atop the block was a two-pound weight, and it was dragged using a string so that each drag had a uniform amount of pressure on it. Paints that showed very little or no scuffing earned the best ratings, and those that showed considerable scuffing were rated Poor.

Flexithane and Superflex’s performance scored ‘Excellent’.
