What are you using to colour it? If its a paint or ink maybe the water in it is causing these bubbles. It might be an idea to try a powder depending on what kind of colour your going for, or if you want it opaque or transparent. You could use some weathering powders if you have them, but they may clump or create a murky effect. Concrete dyes also work well and are great value for money due to the large quantities in a tub versus the amount you need. In the UK I recommend Wickes concrete dye.
What kind of resin are you using? Polyester resin often need a top coat of a different type of resin to fully set, they can remain tacky to allow the next layer to grip. Not too helpful if you hadn\'t planned on another layer but it can be covered over with epoxy glue.
Whatever type your using try mixing the colour in one part of the resin before mixing the two parts together and leave it to settle. This should give the resin time to release the bubbles added when you mix the colouring agent, then mix the two carefully trying to avoid further bubbles.
Edit, I\'ve just seen you\'ve mentioned which resin you used sorry.

I usually use a two part epoxy resin available at most hardware stores. No matter if you stir it together, or \"fold\" it together, you will always have at least some air bubbles.
As far as how long to leave the foodsaver vacuum machine on, it will go until there is no air left in the canister. Sometimes a few seconds, at times I have had it take up to 2, to 3 minutes. Heat buildup can be a problem, but only after a longer time period in vacuum mode. To avoid this, just vacuum it once, let it cool down, then vacuum it again. Unless the resin is quick set ( less than 1/2 hour cure time) you should have enough working time.
Coloring: you can use a tiny amount, I mean like a drop or two of ink in whatever shade you wish. Just DO NOT ADD any dry retardents, thinners, glazes,etc...90 % of the time, these will have a bad reaction to the resin, and muck up the finished product. Hope all this helps
Just remember to try it out on a few small projects first so you dont destroy all of your hard work right off the get go! Good luck! Peace!
