How are artist paints differ from building paints?
Building paints generally are mixed using readily available pigments of primary shades plus black and white which are added to either an Oil, Alkyd or Acrylic Base. Depending on whether the paint is used for interior or exterior, and relative to the amount of wear and tear on the paint, it could contain Teflon for wear ability, UV filters to prevent fading, etc. The polymer used in commercial Acrylic paint dries considerably slower than that used in Artists Acrylics. This is actually a blessing, that I've used to my advantage over the years. It's handy to use a white acrylic enamel interior paint for mixing with Artists acrylics when working on skies, water, or any large areas that require blending as it gives a smooth transition. Have done this for years. Artists pigments, depending on the quality of the paints you are using come from a variety of sources, everything from rocks, to plants, to fish, to bugs, and the list goes on. Depending on the source, some of these pigments are very rare and very expensive, making it uneconomical to use in commercial paint production. Hope this answers your question and hopefully gives you a couple of ideas that you might use.
