  • diluting gesso It always foams

    Everytime I dilute gesso with water it foams.If I use it on a sealed decorative bird carving I have to use a hair dryer to break up the air bubbles or I end up with craters of gesso.I read the you should not use heat on gesso or else it will shrink and crack.I've tried different brands of gesso and the same thing happens.I have used Jo Sonja's flow medium but it does'nt get thin enough.

    I don't think I have ever gotten bubbles when I mix water with gesso?? Are you maybe mixing,beating,stirring a little too energetically? Strange, really no answer!

      You're not using seltzer water, are you? I haven't had any thing like this happen, either, and I've thinned geso down with plain water. 'Fraid I can't help you out on this either.

        Relax, the foaming bubbles are a normal both from undermixing or overmixing. I prefer not to use any water in my gesse-(I use only Jo-Sonja brand)-but dilute it wiyh only flow medium. A good normal ratio is 25% flow medium to 75% gesso. Often, as the gesso gains shelf life, it tends to thicken. You then will need as much as a 50/50 ratio.

        If you insits on useing water as a thinner, then try not to over-agitate.

          I don't have much doubt that I asked these questions to Denny in an email back when I got my Pegas saw from him. But none of my saved emails were transferred over from the old computer to this new one.

          Since what I use mostly is 3/4-inch pine and 1/4 inch multiply which pegas blade would...

          Great work and patience needed to pull off these smaller toys. You did a fantastic job! I really like them.

          I'm curious to know what type of paints you use if you don't mind sharing the brand name.

          Nice precise work Alex, as always from you.

          I also find Celtic these designs fascinating due to their intricacy and geometrical symmetry but I doubt I have your patience to cut them!

          Well done!
