Hmmm never tie-dyed so you can shoot me down if you like, but don’t you have to set the dye for it to take… soaking or [shudder] boiling your shaped blank to get the dye to take seems like overkill to me!
What are you thinking, pass the joint to some else and try to focus and a logical solution.
I think it would be hard to get a tie dye effect straight on to the blank or into fiberglass cloth and is just asking for trouble.
The best result could be achieved much easier by doing a cloth inlay
Use a porous cloth like cotton and as long as the dye (dylon??) is waterbased and set, you shouldn,t have any problems.
Wash it a few after it’s dyed, and do a test with an off cut to be on the safe side.
you should be able to find plenty of info in the aechives and the prosess is not too different from normal laminating, finish with a pin line over hot coat. to tidy the out line up, do a gloss coat (I just love gloss) and you’ll have a stunning psychdelic board
Opps, i’m not sure what happend here, seem to have replied twice, I think that some of your psychadelicness must have rubbed off on me, they say the short term memorey it the first thing to go.
The tie dye pattern comes from putting a stone or hard ball into a fold of cloth wrapping dye risistant string behine this, once the dye has set the string and stone are removed to leave the classic tie dye patten.
So this physically imposible to do this to a blank, theoretically posible to do to fiberglass cloth, but could easily be done by cloth inlay.
DanB asked if he could lam the deck first because he was doing a cloth inlay,
Soulstice gives a good discription of how this is done.
psychadelic jokes aside, (the double post was a genuine mistake) I swear this all makes sense.
What was the question again? is tie dye ever a good idea? does it have mind warping effects?
Edit - sorry spilt hairs chips, the the computer didn’t bring your photo up, I wondered why you left such a large gap,
that marble effect looks sweet now I can see the photo, to be honest my train of thought usually takes a pritty random course, and my mates are constantly winding me up about it, probobly being paranoid, see what tie dye does.
It comes out very transparent like a candy finish… I add the Rit dye thinned with 99% pure isopropyl alcohol to epoxy that is applied to dyed bamboo or balsa veneer panles just to seal the dye previously applied to the wood … This stops any bleeding of color outside of the veneer skin… You could thin / mix the Rit with xylene (sp) instead of iso alcohol I presume, but I can’t readily buy it in Canada, must be healthy stuff??
There’s only really 2 ways to thin or turn Rit powdered dye into a a liquid tint, and that’s by mixing it with either hot water or an evaporating solvent like alcohol…Water seems to be out of the question in my mind… So quick evaporating solvents used to leach the color out of the powdered dye seem to be the only logical option… …Unfortunately adding alcohol to epoxy results in a brittle epoxy mix…
I’m not sure what happens exactly, but I think the alcohol dilutes / desolves some of those critical petrochemical plastisizers, and they evaporate out of the epoxy with the alcohol… This is the reason I only use dye tinted alcohol sparingly when mixing it with epoxy (wood) sealing coats…And the majority is removed with the squeegee…
Adding any form of pigment to natural clear epoxy reduces it’s ultimate strength imho… But can be done obviously…
In response to the O.P.'s question: I’d imagine you could use alcohol thinned Rit dye to tie-dyed fiberlass cloth prior to laminating , don’t know about doing it on the foam… I think it would end up going muddy as soon as you were to start speading out the laminating resin onto the glass though… The cotton fabric inlay suggested above seems most practical…
Cool idea though… Give it a go…
Resinhead: Good one!! love it… I cut my finger with a razor blade doing a cut lap on a crimson red dyed bamboo skin… It blended in fine, so I left it alone…")
I would approach this a little different. I would find tie dye fabric or tie dye an old thin cotton sheet like they did back in the 60's. With the cloth, I fould do a fabric inlay. I do this all the time with Hawaiian print fabic.
