Hi everyone, I just made a new longboard for my brother. Took it out for a first surf last night, rode great but this morning I noticed four pressure dents already. The deck almost feels soft in some spots. Construction is pu foam/poly resin 2- 6 oz top, 1- 6 oz bottom. Board has glossed and polished. I suspect too much resin at one of the stages, maybe gloss. Anyone had this problem? How do you make a real strong board while still totally wetting out the cloth so no weave is exposed? Thanks.
advice i have from a reliable informant, which i plan to use on my next board, is this; prior to lamination, take about a half pint or so of lam resin, thin it to the consistency of water, using styrene, catalyze, and paint onto the deck of the board. then, after it sets, laminate as usual, etc....
new board should be done in about 2 weeks, and i will report as to how this works or doesn't work.

Foot wells. The pro's don't like a board if it don't get some foot wells the first few go-outs!
How long did it cure before taking it into the water? Also, different foam densities will dent more or less easily. A 2 x 6 oz glossed and polished deck, correctly cured, should not dent so easily except if your brother is really heavy or if he regularly knee-paddles (in which case the dents should be pretty much localized.
Thanks for the reply Balsa. Yeah it's weird because it was several weeks between when the board was finished and he surfed it. The waves were pretty good and the board took a few beatings but I don't think it should of dented like that. I'm trying to see if I made a mistake somewhere along the line that caused it to be weaker than usual.
Soft foam??> I have a fish made from light longboard foam, and 2x6oz deck, and 1x6 bottom. It's over 2 years old, and the deepest dent on the deck would be 1/8mm at most, which i think is great considering i've hit it with my head, elbow, knee, ankles plenty of times haha.

hmm.. maybe you took off too much foam from the deck side?
PU blanks are harder at the shell and softer in the inner core therfore shapers plane as little as
possible at the deck side and plane most of the foam from the bottom.
might be your case..
hope it helps,

a)the blank was junk
b)as Lee said above,took too much off the deck. Most likely,the blank.
Sunburst,
What brand of blank was it and what density was it as denoted by the color code. I.E. Red, Blue, Green, etc.
