Can I use watered down liquid foundation with an air brush machine?
In theory you can really use any foundation through an airbrush, but for best results, yes you want to use something formulated specifically for one, and here’s why: In order to pass through the gun without clogging, the foundation needs to be of a very thin consistency, and most ‘regular’ foundations are too thick or viscous, even the sheer ones, for this purpose. In order to get them through, they need to be cut or diluted with something (either water, alcohol, or 244 Fluid which is a Silicone Liquid). The problem with doing it this way is this: when you water down a product…you get a watered-down product! You get a foundation that is no longer performing the way it was designed to be used, as both the coverage and the longevity have been compromised. Think about it this way: when was the last time watering down anything improved its quality?
