Im going to do an acid splash tonight after work. I plan to mix about 4oz yellow tint resin, 4oz blue tint resin, 2oz blue tint with white pigment, and pour it into about a quart of clear resin. I will set each batch off before pouring it into the clear resin and then mix it a tiny bit, not blend. Then I plan to use this to laminate the bottom of the board. Is it a bad Idea to laminate with the tinted resin?. Do I need to color the board and then laminate?
You got it about right. I wouldn’t mix the colors, I would pour them in to the clear quart as a drizzle. It depends on what you want it to look like. If you do it your way it’s going to look like colored smoke on the board, The less you stir the more bold it will be. The more you stir the more mixed it will be, and at the end of your lamination pull it will be green.
Better yet, why not mix a quart batch of Blue tint, then add the yellow, and light blue to that base, drizzling it in, or a pour with a small stir. Just remember to set aside enough colors to wet out the rails and get that cool molten rail color flow.

“Just remember to set aside enough colors to wet out the rails and get that cool molten rail color flow.”
Im not sure I follow what you mean here. Are you suggesting to save some of the color and then drizzle the color over the rails, or save some of the mix and drizzle that over the rails?
How big a board are you making? If using 6 oz cloth, a quart will cover a 9’6" tanker pretty comfortably.
I just did my first acid splash last week, after 35 years of backyard boards. I started with catalyzed yellow, catalyzed a small separate batch of red, poured red into yellow and made five stirs with the stick. That was about four stirs too many, the board is mainly orange with a barely visible yellow-orange swirly pattern along the middle. Lesson: MINIMAL STIRRING!
Actually, I was sorely tempted to go up the street and cadge some suncure, I was wondering about pot life a lot, but all went well. Suggest you consider suncure resin and don’t go really heavy on the pigment.
The key to resin splashes or swirls is to remember that the color that hits the cloth first wins! How you treat the resin will determine the outcome. If you mix the colors then you will get a smoke effect like resinhead said. If you pour the resin together and don’t mix them you will larger swatches of color. If you keep the colors in individual cups and then dump them on the board seperately you will get even larger areas of color. You can even get a mixed effect if you mix a little bit and then dump (sprinkle) some of the color on top. And to add to the confusion the way you pull off the excess resin will also determine the final affect.
Resinhead was talking about color on the rail. If you only let the excess resin you pull off the board hit the rail then you get what we call a “muddy rail”. A mix of all the colors that you put on the board. The best way to make sure you get a good clean color on the rail is to splash some of the original colors on it first so the color will be clean and not “muddy”.
A few more.
Thanks for the advice and pictures. Is it ok to laminate the cloth while doing the splash or should I do it straight onto the foam. Are there benefits and disadvantages of each.

When you do foam drags I have found the color is not as crisp as when you do the splash in the cloth. It is a matter of taste.
Right on man, thats the information I was looking for. Thanks. T minus 1 hour and 23 minutes.
