![]() ![]() ![]() ![]() I also do not recommend trying to spray ready made “acrylic clears” over freshly painted acrylics with “wet coats” as the clears also contain small amounts of organic solvents which will craze your previous paint work. They dry to the touch in minutes as they develop a thin skin but can take up to 24hrs or even days or more to fully cure and gain properties of hardness, adhesion and solvent resistance. The 70’s were CRAZY! The trouble is that they are in fact one of the most technical and challenging paints to master, especially for airbrushing. ![]() Yes, I used Humbrols as an unsupervised child. I also re-started the hobby as an adult with these paints. Low toxicity, they have water as their vehicle layer and so thin and clean up with water and are heavily marketed towards beginners. Modern water based acrylic paints are a technological marvel. Have a water vehicle and both thin and clean up with water. Some solvents destroy the properties of paint when used for clean up. Thinning means to thin the paint whilst retaining performance properties.Ĭlean up means to remove the paint from tools regardless of the properties of the remaining paint which is most often then discarded. The important thing to know then is of course the Vehicle or transport medium as this will tell us more about the paint’s properties but also and most importantly, what we need to use for thinning and clean up. The word “acrylic” seems to have become synonymous with water based paints but in fact many modern paints contain acrylic polymers as their binder and this is why it’s so confusing. It’s tricky as some paint manufacturers complicate this by using the word Acrylic that may appease government agencies restricting solvent paints but who allow water based products for example. Vehicle - is the transport for the mix of the above to travel from the bottle to the model and then evaporate. We need something to help them stick to the surface and that is the…īinder - is the substance that (hopefully!) keeps the pigment on the surface and is often an Acrylic Polymer. Pigments - this is the color part and they are fine powders that do not dissolve but are suspended in the paint. ![]()
