PU vs. Epoxy Surfboards
Which One is Right for You?
If you’re looking to buy a new surfboard, one of the biggest decisions you’ll face is whether to go with PU (Polyurethane) or Epoxy (EPS) construction. While both have their advantages, they offer distinct differences in performance, durability, and feel in the water. So, which one is right for you? Let’s break it down.
Key Differences Between PU and Epoxy Surfboards
| Feature | PU Surfboards | Epoxy Surfboards |
|---|---|---|
| Weight | Heavier | Lighter |
| Flexibility | More flexible | Stiffer |
| Durability | Less durable | More durable |
| Best Conditions | Bigger, powerful waves | Small, mushy waves |
| Environmental Impact | Less eco-friendly | More eco-friendly |
| Cost | Typically lower | Slightly higher |
PU Surfboards: The Classic Feel
PU surfboards have been the go-to choice for surfers since the 1950s. They feature a polyurethane foam core, coated with polyester resin, and reinforced with a wooden stringer for extra strength.
Pros of PU Surfboards:
✔️ More responsive and flexible for better maneuverability in critical waves.
✔️ Feels more stable underfoot due to added weight.
✔️ Traditional ride preferred by experienced surfers.
✔️ Repairs faster with polyester resin.
Cons of PU Surfboards:
❌ More prone to dings, cracks, and water damage.
❌ Heavier, making it harder to carry and paddle.
❌ Less environmentally friendly (polyester resin emits more toxins).
Best for: Advanced surfers looking for a classic feel in powerful waves.
Epoxy Surfboards: Lightweight & Durable
Epoxy surfboards use an Expanded Polystyrene (EPS) foam core, covered with epoxy resin, making them lighter, stronger, and more buoyant than PU boards.
Pros of Epoxy Surfboards:
✔️ Lightweight and easier to paddle.
✔️ Extra buoyancy helps beginners catch more waves.
✔️ More durable and resistant to dings and cracks.
✔️ More eco-friendly than PU boards.
Cons of Epoxy Surfboards:
❌ Some surfers find them too buoyant or “corky.”
❌ Stiffer flex reduces control in powerful waves.
❌ Harder to repair than PU boards.
Best for: Beginners and surfers looking for a durable, easy-to-ride board in small-to-medium waves. This is the more popular build within Florida!
