I did an abstract foam stain with red tint, black pig and clear in suncure lam. looked good. today I put on the glass (the abstract completely cured) and lammed with suncure as I was pulling the resin it started to become pink (resin). did I mention the rails were left untinted, well not anymore. why did this happen? is it something in the suncure or the tint or something I’m ignorant of that I did? please help. this is someone else’s shape, but he’s ok with the mistake. just don’t want it to happen again.
glassing sux just put it in to a shop to get done next time.
you may have used a little too much red pigment. red is sooo tricky. i learned that this weekend.
oz. to a qt., right? I got a yellow on the top that I havent glassed yet and dont want the same results. any help?
not so sure about the ratio. maybe someone can chime in. i use a thick pastey pigment. i never measure the amount, just use my eye. watching it run off the mixing stick gives me an idea of the opacity
mix doesnt matter its done and looks good. I’d just like to know why it’s bleeding.
Too much red in the red tint areas. Next time don’t use red straight. Mix it with a bit of resin before you start your abstract mixing. I’ve seen dark blue tint bleed too, but red is the worst.
I am not quite sure that I understand what you did but reds and blues are very tricky.One thing I might mention is that I always add a little bit of catylist to my resin when using suncure,sometimes UV rays are inhibited by pigments.But you said it cured so its a tough question.Keep on plugging…R. Brucker
UV Cat cures from the top down and can have the appearance of being cured on outer layer, but not fully cured under that layer. Adding pigment only blocks UV rays from reaching below the outerlayer. Probably appeared cured but wasn’t. Jono
I mixed 1/4 oz red tint in about 1/3 qt of uv res. + 1/3 qt. uv res in a different cup + tiny bit of black in another cup. catalyzed the three cups. swirled the black in the clear. poured the lot (two cups) on the taped foam (inlay type 2"from rails). squeegeed. set out in the sun (remember I used mekp too) for about 10min. set over night and all day in the hot shed. cured and cured. layup the glass and like I said as I was pulling from the middle the resin it was turning pink and bled over the rails. hope that helps
Howzit J.R., Greg called it, you should always mix your tint or pigment with a little resin on the side before adding it to your lam batch resin,That’s how I was taught to do it. Aloha, Kokua
i dont understand
Huh?What?Now I’m confused.So you did it on the foam before glassing right?If so why? R.B.
Howzit Mr. Clean, sounds like he tried to color coat the foam before the lamination. To bad he didn’t realize he could do the color in the lay-up. Doing abstract pigment lams used to be a lot of fun back when I had people ask for them. All he did was add extra weight doing it that way. Aloha, Kokua
by abstract you mean like acid splash? or kinda a marbilization? if so yea i like doing them too. it saves the pain of painting, and speeds up production.
yes, that’s what I did. why, cause that’s what the shaper wanted me to do although I did try to pursuade him to do it on glass. he had done it that way before but mainly with opaques which never bled during glassing. Greg made a good point in saying that when you do a foam stain you seal the foam therefore use less resin in the glass. so, minimal weight gain. I’ll post a pic later if I can figure how to do it in the thread.
There was an article on veteran artist Sam Cody in a past surfers journal showing him doing a foam abstract on an Evolution board…he was doing it in acrylic. R.B.
Howzit Mr. Clean, I did an abstract paint job on foam a while back, Kinda tricky getting the paint have the same result as with pigment but it came out just fine. To tell the truth though I think doing them with resin and pigment is easier. I’ve got a pic of the painted abstract board in my files so i’ll see about posting it soon. Aloha, Kokua
