Thread: Weak glass?

    "..... if you go custom, and you get it EXACTLY how you want it......"

    I think he about summed it up with this line.

    A gloss coat is not stronger than a sanded finish. Gloss resin is purely cosmetic. There is no reinforcement (fiberglass) in it. It adds weight and gives the sander/polisher something to make shiny without hitting weave. You are probably just thinking gloss is stronger because most glossed boards (longboards etc.) have heavier glass jobs to begin with. It's the weight of the glass and number of layers that makes the board strong. That and certainly as Brian said Epoxy Resin is stronger and less likely to delam/crack/spider crack than polyester resin.

    The general rule with surfboards and just about anything else performance related:

    Cheap | Light | Durable

    Pick any two you want.


    Wayne might not agree but that is the TRUTH!

    While that may be true that there is no fiberglass to reinforce it it does add an extra layer of glass that is not sanded and therefore more structurally sound before it punches through to the foam. My gloss coat board is a 5'10" so it is not a longboard but is def heavier than a modern sanded finish shortboard and much harder to chip, ding or break. To the OP modern finish boards are not "crap" but they are designed to be lighter and like was stated anything lighter tends to be weaker. It's a trade off and only you can find your happy medium. I will say I have snapped 5 "potato" chip boards and 0 gloss finished ones.

    Yep, firewire, coil, tuflite, sunova are all epoxy boards. So are keahana, hydroflex, xtr, eps. I think most of the labels are epoxy boards these days? I dunno, haven't had a major label board in more than a decade.

    Polyurethane (PU) foam is glassed with polyester resin or epoxy.
    Polystyrene (PE) foam must be glassed with epoxy resin.

    Epoxy can be weak ash!1 too. I think it has more to do with the manufacturing process and glass schedule in the end than what kind of resin was used. I have an EPS blank/epoxy board with a 4/4/4 hexcel schedule. It's super light weight but the thing can't take a hit. Deck looks worse than any of my pu boards. What do I know though? I like a 6/6/6 glass schedule or even 4/4/4 on top 6 on the bottom for a really durable ride.

    A lot of the boards made overseas/mass produced have garbage glass jobs. Look for a signature on the bottom of your board.

    My Phil Taylor longboard I rode over a boulder surfing Montauk on a new moon low tide, slight pressure dent on the bottom NO real damage! I was sure it would be ripped open! Durable boards make a world of difference!

    Ok, so people have been saying epoxy boards are stronger, but I just remembered that the Haydenshapes fiberflex boards use epoxy resin and EPS core and I've heard people say that those ding really easily, sooooooo...

    Are you sure your 5'10" Glossed board isn't glassed with heavier/more glass, ie 6oz? I get that an extra layer of resin adds a bit of physical buffer from the glass itself, but it's proven that the strongest resin/glass ratio is 50/50, so adding a gloss coat on top of a good sanded hotcoat gives no strength benefit, and the impact resistance is negligible (gloss resin is pretty soft so it can polish out easily). The gloss will give you a little more physical buffer and waterproofness, but at the cost of noticeable weight.

    If you want more strength in a shortboard, go with more/heavier glass, rather than a gloss coat.

    This ^^^
    Gloss = appearance
    Glass = strength
