Bought some tempera off a glass shop thinking this stuff would be good on a paint job. But it cracks, notably on my sealed EPS blanks. Haven’t tried it after a hot coat, better this way?
Should I cut it with an acrylic resin, etc? Thinner coats seemd to help, but eventually those showing cracking.
Really funny, becuase on the paint jug it says, “doesn’t crack”.
…hello man, I think the problem is in your technique; I mean, first you should use an airbrush and not a brush.
Apply a coat to “kill” the whitness then apply a few more (depends on the colors and the desired effect), drying between hands with a hairdrier or heat gun (be careful)
The coats are thin and you should thin out at the point you can paint with the airbrush; so not so liquid and not so like it comes in the can.
The tempera colors are like the art stores.
Always on the foam or on the sealed coat; do not work on the Hot coat.

Thanks
thanks reverb.
I’m green to airbrushing, but will likely get into it after the resounding call for it with this paint. Thin it with what? I’ve heard acrylic finishes and water, etc.
I thin my spackle with acrilyic resin (made by Quikcrete for strenghtening concrete) instead of distilled water. Added benefit here is it’s really white, undetectable on the foam and stays whiter under heavy sunlight (did a 30 day test on a south facing deck).
I just want to brush/squeege a solid color on the board and not have it crack. What paint does this while not attacking the foam or compromising the bond to the glass?
uh, well, I think the answer is sealing the blank with a pigmented resin and just donate the paint to a school?
…please read again what I say in the other comment.
There s no better way to paint on foam or on a sealed coat than with an airbrush if you want flat deep color without adhesion problems in the lam.
So, if you do not have an air compressor, better leave the board White.
If you do not know how to paint, will be even more difficult and with too many hassles to use color on the resin; even more with epoxy resins if you are a rookie.
Still you did not answered me about how to put the A E in your nickname
See the picture
Acrylic paints. Tempera paint is for Pre-school finger painting. You can eat that crap! Remember Kindergarden art? Same paint. It cracked too!
Thin with water. Acrylic works good too. It does help the paint bond with foam. Tempera paint has no binders. That’s what makes it bond and stick to the surface.
A good quality airbrush is a combination of airbrush gun control, properly mixed paint consistency and flow.

Good luck, Barry
cool thanks.
Hahahha!
But…there’s no way Bestemp (makers of large-scale tempera) still use eggs to make this stuff…or yes? --F#@k me if that’s true. Has to be acryillic based or some chalk medium now. Michelangelo made tempura direct from eggs. Today: it’s gotta be a lab chemical…
awesome work. really cool.
Barry is right and his work is tight, but tempera paints really work fine for painting surfboard foam, and really all you need is a stiff brush, and a bit of technique, and you can be successful. Still his paint work blows away mine so the best advice is his.
Before I started spraying boards, I was thinning good quality acrylic house paint and using a roller. Use the best quality roller with shortest nap you can find… 1/4" will work. A cabinet painter/artist taught me that. Two thin coats got good color and no cracking or bonding issues. This was over sealed EPS.
Hi Vaeske-
All the guys have great advice. I airbrushed for many years back in the Eighties and Nineties but not too many EPS blanks back then. We use Tempera paint all the time on EPS blanks now, the main trick is to not put it on too thick. I was always told to mix the paint to the thickness of whole milk. It’s best to put on thin coats and let it dry between coats. You shuold be able to brush the paint and not get cracking just don’t get it on there too thick.
Best of luck-
Brad
A good quality tempera paint will last forever. Some of the oldest painting known are egg tempera paints. Ever see photos of those Roman ruins with the murals on the wall? Maybe those Roman and Greeks had really really talented kids playing with their finger paints. ( no offense intended Barry )
I have mixed tempera with an acrylic binder. Seems to work just fine. However just thinning with water seems to be just as good. The quality of the Tempera colors are great. They have nice sheen and softness.
If tempera is what you have you can make it work. That’s basically it. If your putting the paint on so thick that it cracks, that’s what I would call operator error. The best paints we can’t even use without a spray booth and permits, but silly old kindergarten tempera, the kind the special kids were eating does the job, and unlike lots of crap in this industry is relatively safe in the right hands. Not necessarily the best, but good enough. Like Terry Price at Cerritos College used to always say: “Quick and Dirty.”

Cool. Noted Thanks everyone.
…hello Barry Snyder, tempera and acrylics are what is used to paint Surfboards.
Here in this forum are lots of guessers; long timers that now are retired and many shapers that in reality never painted a board or painted couple or glassed a few boards, etc
so only few boardbuilders that still live from this labor; like you…and me too, so to still have a shop open the builder needs to do the things right…more if it s a custom shop, like you have…and I have…so I wonder why do you say that about tempera colors.
85% of my boards are colored, I airbrush several days in a week or in a small % I put pigments and tints on the lam. About 12 years ago I used exclusively acrylics from Dutch land BUT the Reds, Greens, and other intense colors almost all the time tried to bleed me, so I started to use temperas most of the time. In the last 10 years a order my colors directly to a small color factory. They make those colors used by the children in the school and the colors that you can paint your body, etc and those ARE NOT exactly the same as a tempera composition, have some subtleties, that makes for a different product.
All these sound a bit rude but this is not my intention, but may be Im pissed off like Huie or Ghettorat.
-Hello Monkstar1, thanks seems the poster do not have to response me, I do not why, but he eluded the answer…
However, I do not know which is the “OPTION” button…?
To bad there’s not an “option” button next to your name.
Reverb, I don’t really have a problem with Tempera paints. It does work. It’s just not the same quality as acrylics.
Because Tempera has no binders, it does not stick to surfaces to well. It will work for limited uses like solid sprays. I do some pretty complex tape-offs. Multi layers. That means alot of taping on the paint directly. A good quality acrylic can be taped on all day! I don’t like to fix paint that has been pulled up or off.
I do use Tempera. Like these.
Best-temp. Day-Glo.
I use these paints mixed with Acrylics.
It is cheap priced.
However, Nova paint is the best paint I’ve ever used. Durable as hell. Acrylic.
Thats how I get such dark black colors.(I do alot of black!)
Use whatever works for you.

Barry is right Nova paints for surfboards rock, and given a choice that’s my preference. And he is a top rate or rat, (hoodrat) craftsman. Kind of like me and the Skil 100 that’s the best, but a piece of 36 grit will work too with a bit of effort. Anyhow, I am not mad, maybe Huie is, I don’t know? Barry is my friend, and if he hasn’t figured out who I am he will. He rocks, and he paints boards better than I could ever imagine myself doing.
