- Does tinting resin during laminition weaken the board?
- Is there any kind of tint that weakens lams less or at all?
- Cheapest/best place to buy tint online?
Sorry for all of the questions im newish. Thanks.
Yes, too much tint or pigment will alter the curing of resins and render them weaker or even rubbery. Just a little dab will do.
Pigments tend to affect resin curing more than tints do.
To dial in the color you want just mix a little tint into the resin (before adding catalyst) and spread a bit of that colored resin on a scrap piece of foam. The color will look much darker in the mixing bucket than on your board. Add a little more tint at a time to get your desired color. The add the catalyst.

Thats a great idea! I also forgot to add I will be using epoxy by the way.
Tints can be used with epoxy. Just be sure your resin and hardener are thoroughly mixed prior to the addition of any colorant. Remember, just a dab will do! The less you use to achieve the desired saturation the better. The reason is that the more you add the more the resin is diffused. So be frugal.
I'd like to see a study done on whether or not tinted boards snap more often than clear boards. Maybe someone could get a grant from kahuna obama and do a little research on the subject.

Maybe on a micro level...but most surfboards built with color have extra steps that make them stronger.
You need to learn about how basic shortboards are built vs longboards like Cooperfish..........
You also need to learn about "tint" vs "pigment".....and airbrush........The color work does not make the surfboard weak or strong......

I was thinking about spray painting the board white after lamination and then putting the hot coat on or would that chip too easy.
Pigments in epoxy will make them rubbery, not so much in poly. In epoxy you really have to use quite a bit to get the rubbery effect. This can be a good thing if you want a bit more flexible epoxy in certain areas..like tail sections and what not. So if you plan it out you can get a different flex pattern with different amounts of colorant.
But if you are just doing a surfamabord den you should be ok with the standard glup of glop in da epoxy.
If you are putting it over EPS, your biggest challenge will be epoxy in the voids between the beads. if colored epoxy gets into the bead voids, it will show up as a darker area, because of the depth of epoxy saturating in...subsequently highlighting the beads with little dark rings. So if you are planning on doing an EPS blank with epoxy my recommendation would be to seal the blank first with a slurry of epoxy and microbaloons, or babby talc powder, not spackle or DAP FastnFinal . Using Epoxy will seal the voids with clear and give you a nice even surface for your color. (This is a must do if you are doing a tint, opaques not so much)
