Hello…I’ve a 9’ EPS with the usual 6/6+6 glass job. It’s a great custom board, but after taking more than a few hits from the lip, I’m wondering if I should add a #4 to the bottom; I’ve noticed a few shapers/glassers here add that extra strength to their EPS boards.The other part of this question is, will adding an extra layer of glass after the initial lam be as strong ? Thanks
Wouldn’t do it myself, but yes, you can add more cloth later. Just like a ding repair, you would sand off top resin. Sand until you just kiss the existing cloth. Epoxy over existing epoxy. Resin over existing resin. Resin over Epoxy might seperate.
I did it on a board i make for a friend that it found too light. After good cleaning I sand top coat with my orbital sander and 40 grit then lam, no problem, this board is 3 years now and take serious lip of hollow hossegor beachbreack.
I did it again the same on a board (not from me) with a poly hotcoat on epoxy lam, well sanded to see waves of fiber but it’s separate after an impact.
