How do I tell if my board is epoxy or poly?
How to tell if a surfboard is epoxy or PU (poly)? Epoxy surfboards are opaque and more durable than PU surfboards, which are more fragile and have a clearer resin. Epoxy surfboards are lighter and more rigid than PU (or polyurethane) surfboards which are more traditional in construction. Softboards are generally easier to handle due to their larger volume and buoyancy, which makes paddling and staying on the board easier. However, hardboards require more control and technique to surf more smoothly.With their increased buoyancy, epoxy boards are more difficult to duck dive, and for some surfers, feel too light when cutting through the water. They have less hold in the rails, less flex, and less memory foam making them stiffer and harder to turn.
