I just ready to start glassing two blanks and was informed that paint can be used as a pigment. Because of using EPS, I’ d like to pigment the resin white to try hide some of the blemishes in the blank. So to my question, what kind of paint should be used? Any specific things to avoid? thanks dave (I am not able to buy any true resin pigment around here, therefore i am looking for an alternative)
the internet is a wonderfull thing order pay and 4 days later its at your door. Good luck…
I have wondered this same thing… can you use acrylic paint as a pigment? Why do you say “Don’t use paint”? Does it mess with the reaction? Resin doesn’t harden completely? Brittle? Weak? What’s the draw back? Does it behave to same for both epoxy and poly?
I doubt acrylic paint will work. Never tried it, but common sense tells me that it won’t. The binding agents are different chemical makeups between acrylic paint, and resin.
Not sure if it would work in epoxy, maybe because they say you can clean it up with soap and water, but again, I doubt it.
BUT, feel free to test anything you want. the best way to learn is to try and fail.
Oil paint might have a better chance, but with resin pigment being relatively cheap and readily accesible via the web, why would you want to.

DON’T mix paint and resin.
DON’T mix solvent based (oil based) paint and any kind of resin.
The vehicles are different. If you don’t know what vehicle is with respect to paint, that’s another reason not to do it, unless you like to waste resin.
That said, you can paint the blank using water-based paint, then glass it. However, know that the bond between the glass job and the foam will be weakened. Also, know that the glass/foam bond is the first thing that fails when a board breaks in two. Weaken that bond at your own peril - heck you can always make another.
Whats goin on,
Tudors model paint will work as a substitute for resin pigment.

Hey Charlie,
Can you explain a little bit more (or point to a good source of info) about:
“The vehicles are different. If you don’t know what vehicle is with respect to paint, that’s another reason not to do it…”
Also, concerning your comment on the foam/resin bond being weakened by a painted blank, does that imply that any sort of on-blank art work (sprays, brush-jobs…etc) weakens the bond (and therefore the board)? I could see how that might be the case as you’re saturating some level of the blank with paint rather than resin, but is that only the case if the paint is laid on too thick, or a general rule even with light sprays/brush jobs?
Thanks,

Good thing I read this before I went along, I was told a a boat supply store that paint would be fine to use…guess not. So this Tudors model paint works fine? Ill have to test it out. Thanks Dave
I was told way back when that model paint would work as a pigment substitute also. Never tried it though. Model paint is oil based, and I would guess that at best, it would weaken or change the chemical curing process and have negative effects on anything it was used as pigment.
Between fiberglasssupply and foamez you can get good pigments that would be cheaper than model paint in the long run, and delivered to your door.
