Is PU or epoxy better?
The main difference between this type of material and the epoxy systems is in the molecular structure of the two, which affects how the molecules fuse together during the curing process. Essentially, polyurethanes have a higher cross-link density than epoxies, making them more durable.
Does EPS float more than PU?
EPS foam is much lighter than PU, which makes for a great option for the surfers that love to take it to the air. They are easier to whip around quickly, which makes them great in the air as well as on a wave that lets you perform quick, snappy turns.

To answer your question in short order, Yes, surfboards do loose their “pop”, sort of like skate boards, and yes, the older a surfboard gets, if ridden, with or without a “buckle” or ding, will become “less stiff”, (less responsive) because of the natural breakdown of the materials it's constructed from i.e. natural ...

How can you tell the difference between epoxy and fibreglass?
The most significant difference between the moulded epoxy boards that we tested and fibreglass boards is that you know that an epoxy board from a particular mould is exactly the same size, shape and weight as the next one.
What volume board should I ride?
As a general rule, a beginner should be riding the equivalent of 100% of their body weight in volume. I.e. A beginner weighing 80kg should be riding a surfboard around 80 litres in volume. Alternatively, an experienced surfer can ride a surfboard that's 35% - 40% of their body weight in volume.
Is polyurethane the same as resin?
Polyurethane resins are synthetic resins that have two-component systems using a combination of resins and hardeners.
