Hi
Anyone out there help me. I have airbrushed 2 different cakes with food coloring and the coloring comes out of the airbrush blotchy instead of smooth. Is there some sort of mixture ratio I should know about?
Thanks
What ratio are you talking about? I use the airbrush colors straight from the bottle! Sometimes this happens if the little sprayer gets clogged, try to clean it out a few times, maybe something got stuck thelast time you used it?
Are you using "airbrush colors" or the liquid food colors? There is a difference. Airbrush colors are specially made for use in airbrushes. Food colors are not, they are usually pigments dissolved in the medium (water based, or alcohol based or even oil based) and they should not be used in air brushes as they will clog the nozzle.
If that's not the prob, you might have a bent tip on your needle or your airbrush might be dirty (from buildup, not negligence) about every fourth or fifth cake or if you don't plan to use the brush for a while, you need to use the cleaning solution in it and dissasemble the airbrush and give it a thorough interior cleaning.
If the needle tip is bent even the slightest you will have probs with the spotting too. To fix this if it's just a little bent, you take out the needle and carefully run it between your finger and a hard surface (pulling back, one direction only) til it looks straight. Re-insert it and see if that helps at all. If that doesn't help you might need to get a new needle. (not really that hard to find online)
Hope this helps.
ok it's me again. Just had another thought, if you plan on doing a lot of airbrushed cakes, invest in some inexpensive dust masks) The overspray can cause probs in some people. So to avoid probs in the first place just wear one of those whn you are painting.
Safety first.
