how much tint?

General Discussion
1

I am glassing a long board with foamez resin tint. How much tint should I use per side?

 

2

What tint have you got and what color do you wish to obtain? PE or epoxy?

3

I have the foamez tint in blue and green. I am glassing with epoxy. 6oz bottom and 6+4oz deck with cut laps.

Should I glass it with that schedule or instead tint a 4oz layer on each side plus a clear 4oz on bottom and clear 6oz on deck?

Doing the color first and then free-lapping clears over might not be a bad idea if you're inexperienced. Cuts will be easier and when you sand you won't hit your color. It won't be the lightest possible glass job, but that may not matter to you. How you sequence things also depends on your color scheme, what are you trying to get?

I would like the glass to be light, that might not be possible if I have to lam twice per side. I was going to butt the two cut laps together under the pinline then at least one extra 4oz of clear on the deck to cover the seam and free lap it on the bottom. I am not that inexperienced, though I have never done a tint job. It will be two clean colors, they will not overlap.

What would be the best way to do the tint?

How much tint should I use per side in the epoxy? I think it will be 12-14oz of resin per side, or a little more.

OK, that's called an ''inlay'' when you do color inside the cutline of the first side and then clear over. I kinda figure that's what you were doing, and that's the proper way to do it. Tints vary, so it's hard to say how much to add to resin. It needs to look fairly dark in the bucket when mixed, as a thin layer will lighten considerably. Maybe someone else who's used those exact tints in epoxy will check in....

by using epoxy you will be traping yourself in a corner..

usualy with epoxy you add the tint after the resin and hardner are blended

so you cant double up the mix and save half for the next side

therefor you must carefully measure the tint you use for the first side

and mix the same for the second side

you will waste some epoxy when you lam the deck inlay but oh well,,sacrafices must be made.

do the bottom in 6oz with tint then 6oz inlay then 4 or 6oz clear over the deck (I would do 6oz)

thats all I got

"How much tint? "

before you mix the resin and hardener  prepare a scrap piece of cloth attached to a flat piece ot EPS or any other stuff

that would give you a white backgroud.  

then mix your  resin+ hardener for at least 2 minutes and then  add small amount of tint.  drop some tinted resin on your scrap test panel  and see if you like  the colour.  

 if not , add some more tint....and so on...  with epoxy you got plenty of time anyway and this process takes

just over half a minute so you'll be fine.

so to your question " how much" ..    this much !!!

:)

good day , don't forget to post pic's huh

I’ve only ever used polyester, but I’ve been using the Foam E-Z tints and I feel like I read on there that you should never go above 1 oz. per 16 oz., which seems like way too much tint to me anyway.  I usually take the small cups (used for hardener and catalyst) and add tint about 5 to 10 cc at a time and have found that by the time I put close to 15 cc in there it’s right at the color that I want.  The first time I used tint I probably got pretty close to 1 oz., and it seemed like it took much longer to harden, and then was way too gummy when sanding.

 

Don’t know if epoxy is much different, but I think since it’s just color tint the numbers should be the same. 

So: ~ 15 cc/0.5 oz. tint per 16 oz. resin

 

If I’m completely wrong, set me straight, por favor.
