In this three-day workshop we will look at the application of a thin paint “Imprimatura” layer with thick paint “Impasto” using acrylic colours, plus mediums, Heavy Gel and Molding Paste to extend the paint’s thickness. “Imprimatura” colours will form the foundation colour (thin) layer that will accent the top expressive thick layers. Using Heavy Gels and or Molding Paste creates a painted 3-dimensional surface. This can be built up with brushes, palette knives or any other form of scraping tool that an artist wishes to use. Either representational painting or abstraction can be successfully arrived at with this technique. Artists from Soutine to Tom Thomson relied on thick undulating brush strokes applied over Imprimatur coloured foundations for their personal image expression. Canadians Jean-Paul Riopelle and Harold Klunder both used this technique with palette knives, scrapers and brushes in their abstract works. If you don’t wish to be a finicky or realist painter, then this technical approach is a suitable technique to discover. Through instructor demonstration, Power Point slide show presentations and practical application, students will be introduced to this versatile painting process.
