So I have painted boards before, all of which have been BASIC’s brand acrylic on top of the finished hot coat then sealed with clear auto enamel. They hold up real well and evry couple of years give nice touch up spray just from wear and tear. About to finish up a longboad blank out of PU foam, was thinking about trying to paint on the foam this time, nothing crazy just simple lines most likely. Using UV resin, and would prob seal with clear acrylic, then lam over with some hardener added to help it kick. Or could go with the standard top coat after sanding. Not so much worried about methods, just curious to see which way ,and results you guys/girls enjoy more.
Surprised that the basics are holding up. They do not have much in the way of UV protection in the paint.
Well one of the boards the bottom is painted, and the one with the top painted gets stored in a bag, and since I ride in the northeast not to many days where it is just baking in the sun,
Most blanks are painted foam, a few do as you have been doing, on the sanded hotcoat. Just about any flat acrylic paint sprays well onto foam. I have used lots of flat house paint purchased at Home Depot. Never had a mishap. Tempra and artists acrylics work well also. The best red I’ve used (and still do) is the tempra from Walmart. Plenty of options. Nova and paint purchased at places like Fiberglass Hawaii and Foam EZ are favored by those that frequent this forum/site. FLAT only. Strain and thin as necessary Dry throughly before glassing.
Thanks MC ding - Once I get my camera fixed hope to post some pics. Dont have a fancy pic phone.
OK jolly mon. Just keep that hairdo under a towel.
Forgot to ask I know some people have some had some issues with orange or red paint under the UV resin, the catalyst should circumnavaigate this though correct? Ill be doing black too but probably a really thinned out almost opauge color.
Does not compute … “black + really thinned out + opaque”?
Cutting the black with some Gray and white, over the foam for about 1 inch thick lines. Giving it a more stone, then black acrylic paint look.
With deep dark colors you can get a little crystalization. Sort of a sparkily affect in the glass. You can seal the paint with some acrylic sealer and this may help or minimize crystalization. No guarantees. I got a couple of pastel EPS and Epoxy boards back form the glasser that had slight crystalization. You had to look really hard to even notice it though. Very common. PS Darker colors; reds, yellows, oranges can sometimes slow the UV set. A little catalyst takes care of it.
thanks for the help guys I will let you know how it comes out.
Cool! looks good.
…you cannot apply a gloss coat onto a clear coat…
Sorry I ment laminate coat. Got the two lam coats down yesterday, Then it started getting too windy for the uv cure, and now getting hammered by some snow. That Uv stuff retains a sweet funky smell for a little bit thats for sure. As soon as the sanding coats are done and the fin box is in ill try to get another pic up.
