Any views on how long it takes a PU board to lose its spring. Is this an urban surfing myth? I've often wondered.

Been riding a board with a Burford blank for about 5-6 years. Probably ride it about it about once a week at least, It's pretty yellowed up now (sun drenched from living in the back of a car).

Interested to know your views lads.

Once the deck's sunk so much that you've lost 2litres + of volume ;)

I think the stringer and type of glassing has the most effect.

I reckon it would vary considerably based on a whole lot of shit

It’s not an urban myth though. Polyester resin brittles out over time, you can beat up the foam core through repeated impacts and pressure, and little leaks here and there from minor fractures in the laminate will assist that foam breakdown.

There’s no way back from it though, once a board goes it goes. Epoxy resins definitely help protect a board from the process

Cool, thanks Nick. Yeh my deck is caving under my back foot. Might look at an epoxy board.

PU cores last a lot longer than EPS cores though.

I'm really not sure about that whole PU board losing it's life thing.

I've got poly boards 20+ years old that surf fine.

Few years back I was marooned without a shortboard....it was the great winter of 2007 and I'd snapped all my shortboards. A mate said I've got an old McCoy under the house that you can take.
It was more ding than board but I made it watertight and got it back in the water..........fcuking surfed unreal for the rest of the winter. That board was made in '95......it's still under the house waiting it's next go out.

well yeah that's why PU/epoxy is generally the go

they definitely break down, it's just a matter of how often you surf 'em and all that other stuff. I have 20 year old boards that go fine too but I don't surf 'em even once a month.

I understand that is a technical and scientific reality but for the life of me I can't find any practical proof of it in terms of my "lived experience".

PU/Epoxy gets just as trashed on the rocks, dents just as much and I can't discern any difference in feel on a well ridden 5 year old board between it and PU/PE.

I might not be sensitive enough to detect the difference or there may be confirmation biases or placebo effects at play.

With polystyrene/epoxy you can put in a stringer, 6oz on the bottom, a 6 and a 4 on top and still have a board as light as a PU with only 4 on the top and 4 on the bottom :-D-:

Well the other obvious factor is exposure to UV light. That rots fibreglass and resin and makes foam collapse. It's funny that spray painting a protective coat hasn't become a thing on Poly Boards.
Always find it funny to see boards sitting naked on backpackers balconies for months.

Are you talking about painting the blank or the glass?
Grant Miller told me he paints his blanks white to slow the yellowing process.
All the Tuflite boards I’ve seen had painted glass.

painting the blank white can interfere with the chemical bond between resin and blank.

keep them out of the sun when not surfing.

two things.

It sucks water (scientific fact).
And it doesn't ride as well as a PU core (subjective reality for many people).

I was thinking about painting the glass. Does tend to make you rash more but hey the boards last longer. It does show how conservative manufacturing processes are that they haven't really addressed this.
