Get the best of both worlds: the industry-leading clarity of Silmar® 249A and the convenience of UV-cure technology. Manufactured in Hawthorne, California, Silmar has been the undisputed choice for professional surfboard builders since 1961.

This UV-Cure Laminating Resin is formulated to give you "infinite work time." The resin remains liquid and workable indoors, allowing you to perfectly saturate your fiberglass and pull your laps without a ticking clock. Once exposed to direct sunlight, it reaches a hard cure in minutes.

Product Highlights:

Premium Clarity: The gold standard for clear, professional surfboard finishes.

UV Activated: Does not harden until exposed to sunlight or a UV lamp.

Tacky Cure: Specifically designed to cure tacky for a superior chemical bond with your hot coat.

Convertible: Can be converted into a sanding (hot-coat) resin by adding a polyester surfacing agent.

Shelf Life: Guaranteed 1-year minimum shelf life.

Pro Tip: Perfect for garage builders! Take your time getting your lamination perfect in the shade, then simply walk the board into the sun to "freeze" it in place.
