Painting 33

Ref 970.- Watercolor.- Painting over a modeling paste layer and this one; over cold press paper

 I have been using very extensively as textured ground for watercolors, gouache and acrylic. It works great! When dry it's very, very absorbent and you will have no issues with the paint coming off the paste. I laid down the molding paste after a detailing sketch indicating basically shadows and darker areas, then fix to avoid stains, marks and/or blots, thereafter apply with an spatula the molding paste  let it dry completely (a day or so) you can then mix and slathered with the wc and/or paint above it. The dry molding paste just sucks it right up. for my next painting I paint over it

Your bigger worry is choosing the appropriate support for the molding paste. It ought to be fairly rigid, so the paste stays in place and doesn't crack or chip off. It's a little bit flexible, but I wouldn't take chances. I used Gvarro paper  240 gr rough wc paper, the gouache paint "White & blue" reflections were made with opaque watercolor (gouache) below and above modeling paste which is partially transparent and give the 3D sense when it applied correctly (the tickness of modeling paste is really quite minimal but enough to créate a good job
