Gloss Resin used instead of Sanding Resin - Oh Dear?!

General Discussion

Hi All,

I think I just did a bad thing…I ran out of resin when finishing my 9’5" stealth noseriding longboard so I grabbed what I had to hand, which was a Taupo Gloss Resin made by Seabase to which I added the right amount of Wax in Styrene and MEKP.  Basically I tend not to bother with gloss usually and so have not used it and when I ran out of sanding resin I used gloss instead - it has set up real nice and looks sweet, but I just want to know how this might affect the board - if at all.  Will it make it more brittle etc?  I have one coat of gloss left so I could double up to make it less brittle…

Also  if I leave it unsanded and unpolished (it has set up real smooth) then surely this will be OK and prevent wicking right - polishing and sanding without machines is just such a bummer??

It looks totally rideable and I reckon I just need to get in the water - or am I nuts?

I am an amateur builder and am not totally hell bent on perfection so I can live with this error of judgement as long as my board works.

Any knowledge would be appreciated.

You may very well leave it as is (i.e. without sanding) but you will have a small “ridge” along the rail where top and bottom coats meet and probably some more weight, too. Also, even if you think that it’s real smooth, it’s actually not. Just running some 320 or 400 grit paper on it will show you all the micro-irregularities that you don’t see right now. BUT such micro-irregularities are really nothing compared to pieces of wax that your board’s bottom will almost invariably collect when you slip it in her bag the wrong way, for instance. So… The real problem can be weight because all unnecessary resin should be sanded. Of course, hand-sanding and polishing is hard work (and doesn’t lead to a great finish either…)

Well, harkening back to the ''Balsa Era'' we only used one resin.   Gloss resin.     We did the lamination, the hot coat, mounted the fin, and did the gloss all with that one resin.   So, I don't think you should lose any sleep over it.    Sand it, gloss it, and go surfing.

Hey Balsa thanks for your comments.  So the wax will flek if not sanded is what your saying - so basically I should bite the bullet and sand and polish in order to avoid the wax causing problems and to reduce weight (it does seem a little heavier than anticipated).  And yeah I get it about the ridge - that has happened.  

But in principle the fact that I have used Gloss resin instead of sanding resin should make little difference as long as I sand and polish it right?

Bill - thanks for your reassuring message.  If there is one thing I have learnt in surfing, and in particular board design, it is to respect the voice of experience and you clearly have that in abundance.  Thanks - I will do as you have said.  Since 1958 man - respect!
