The Balsawood boards that I built and still do are glassed in Polyester resin. That come out really clear. Balsa does not have any oil in it so you do not need to use epoxy. When using exotics you have to use epoxy because the wood is so oily. I would think that these boards were glassed in Polyester. However Bert would know best as to what he used.
dont use polyester resin under any circumstances!!!
the core is styro on sunovas
and polyester resin will melt it
it will seep through any small holes and damage the core bigtime
the boards are deffinately epoxy
so make sure u use epoxy resin only for repairs
and dont use solvents at all (like acetone) as not only being a poisonous they will also melt the core.
don t know about the gloss but id say it prolly polyurethane or acrylic
btw
bert doesnt post here very often or at all lately
My Balsa’s are chambered. I was refering to glassing solid wood not EPS core… EPS requires Epoxy. Sorry for the confusion.
no worries mate
i just imagined meltdown
Thanks Paul for keeping it straight!
i have been making balsa ,carbon, full epoxy samwich boards for 3 years and windsurfers for 7 so i hope by now i know a thing or two about composite construction . the reason behind my bert question is to see if there is a faster way to repair his boards . i would be happy to stop repairing them all together but its hard to say no to everyone who brings balsa boards to me cause there great boards and there is no one else i can send them too .
on the point of polyester on eps ( polystrene) yes it can definitely be done i have made a few short boards what you need to is apply at least 6 coates of bondcrete its like water down pva glue , it forums a barrier between the foam and resin .
you end up with a very lite board but because it has no stringer and its polyester unless you use alot of glass they do not have compression strength and will fail in a short time
hey kaos
bondcrete eh?
hows the peel strength of resin to the boncrete
i might like to try it to seal my eps blanks
would you recomend??
when bert use to post here i remember that he had mentioned that some of his boards are finished in 2pac urathane, i believe that the brand was upol…
just passing through …
anything numbered before 1712 was ciba geigy epoxy lams , epoxy filler/hot coats and automotive acrylic clear (the sludgy stuff when you sand it )
1712 to around 2900 was FR 251 from F&R sales in welshpool as lam and various coats , then finished with a home blend polyester finish coat as a gloss , 2900 through to 3150 were epoxy lams and a 2 pac finish …
they are the basic resins you would find on the outside when doing a repair …
once the repair is finished and sealed , even an automotive single pack acrylic will give a nice shine when buffed , it just scratches a little easier …
can i send a truck load of customers around ???
pm me your address and phone number if you want some more work …
will give you tips on appropriate techniques if your interested …
heard west oz has been smoking this year ???
ive been scouring the coast over here in search of a left with a lip that actually throws when you think it will , but i have yet to find one …
lost in the land of endless rights , bright city lights and working nights …
