Just got some epoxy pigments and started mixing them to match colours on ding repairs. But not so easy as I thought. Pigments are thick sticky goo in small pots. I need to make orange. Use a toothpick to put a blob of yellow in the resin, then another one to add a blob of red. Not the right orange. Need more yellow. Cant put the stick thats been in the resin back in the pigment pot so another stick. cant get all the pigment off the stick. Next batch tried using a gloved finger tip. Messy. Smear it on the side of the pot and try and mix it into the resin. Need some more. Off with glove another glove. More pigment. Then another glove. What a waste! There has to be an easier way to do this. Put pigment paste in a syringe without getting it everywhere? There is surely a simple way. Help!
put it in a squeeze bottle.
A color can never be mached perfectly unless you still have some of the origional reson left from the lam. The rebuild wil also affect the color as it wont be pristine foam. Get some acrylic paint and apply to the cured and sanded q-cell mixture and realize the glass will throw it off a bit blue and the resin will yellow over time.
Now you know what some lowly employee at the the local supply house goes through pouring pigment out of gallon jugs into smaller containers so that you can pay $10 or $20 for a two to four ounce jar .
The easier and proper way is mentioned above.
You will never match a ding with pigments because you cant blend it. Do as above mentiones..but heres a bit more detail.:
1) fix ding
2) spray ding white with sprayer water based paint., go buy a little hobby job sprayer. Painting white will make the final paint coat a lot easier to match and cover.
3) glass, hotcoat, and sand ding smooth to 220
4) paint ding with color that batches board. If you need to do pinlines do that too. Do all the color work you can
5) now spray over the area with UPOL 2 pack or some similar from automotive store clear urethene. In a pinch you can use Krylon clear gloss etc.
6) Buff and shine out.
mixing colored resin: Colored resin will never match because you have a varried thickness of resin..ie., red epoxy real thin will look like pink.....red epoxy real thick will look like blood. But paint is paint.
Colored resins or epoxy is only for the initial build of the surfboard. You will drive yourself crazy trying to match for dings..It will never work.
My computer has a program called “paint” on it. If you click custom colors you will see a big chart full of colors, and it makes it easier(at least for me) to mix colors cause I know how much more or less I need to get the final color. hope this makes sense. good luck
Much useful information thank you. Much to think about.
I have a set of artists acrylic paints - can I use those thinned with water? With a brush? Put them in an air brush?
What about acrylic spray paint in a can? Can you put resin over that? Or is preferable that all colours are water based acrylic of some sort?
I think I got the idea of mixing pigment into the Q-Cell from Moura / aka Lord of the Dings but he also uses a spray gun.

If you do decide to do the colour matching, I posted a reply in the following thread link that might be useful…sooner or later :).

Cheers,

You can accurately match color but, you need a good idea about color, I had a laminator who was the absolute WORST at mixing color (Atomized knows who).
A customer brought me a Hobie with deck panels, they were wake surfing and it was kicked into the prop, it slashed the one side of the nose to shit, had to replace the foam.
The deck panels were a red-orange, got everything glassed, sanded, taped off, mixed up the red and yellow, took a drop of the uncatylized batch and put it on the sanded / feathered part of the panel and floated a few drops of acetone over it, this mimicked the look after glossing. Added a few dabs of yellow, did the same test again, added a bit more yellow, repeated the test. After about a dozen tries it was not visible against the background color, shot the color and feathered it in. When glossed you could not tell the color had been repaired, although you could see half the nose had been replaced, it was Jamma Kekai’s board, I had to do my very best
