You Asked – Thickening Acrylic Paint

Today’s question comes from Jeff

Jeff Writes:

“I work with acrylics. I enjoy painting thickly with Impasto only the various gels and other thickening mediums are becoming too expensive for me at this time. Are there any other ways to add body to acrylic paint? Perhaps with substances one might find around the house? I read in various book that one could mix joint compound, sawdust, plaster, corn starch etc. with acrylic paints.  “

Do you have any information that might help Jeff?  Please leave your response in the comments box below.

    I have used fine sand. It makes the paint thick, but of course always leaves some visible structure. But it works pretty fine. Never forget to clean the brushes extra carefully though, because otherwise the sand ruins them.

    You could try a product called Whiting which is available from some hardware stores and some art stores. Also, jolting compound will work to a degree, but only if you use a little and bear in mind that it dries very quickly.
