  • 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 often resize just to fit the size of the wood I have on hand. I agree this is a no win situation because of the various software, hardware differences plus the skill level of us, the end users. Even providing the patterns in a digitized format will no fix this because of the reasons I already mentioned....

          John your original post is a valid question. It is a simple thing to put in the original scale assuming that it was on the original drawing. As a minimum the size of the material required can be stated, although that has been a confusion for folks that have built the clock projects. I field a lot of...

          Maybe nothing has changed ? But is there anything that can be done to make it easier. The very large projects are difficult to copy over several pages and put together properly. I believe in making improvements and not preserving the status quo.

          I enjoy the challenge of cutting a project...

          This is not a problem with the magazine for my issue.. It is a problem with the book having resized the drawings without giving the actual size.

          I do again apologize for my post.. I cannot use the right words to explain it.. so maybe someone should just remove the post....

          Reading these replies, I am still trying to figure out what the problem really is. I haven't noticed changes in how they publish recently and I don't think I ever had trouble making copies of of the patterns I want to cut.

          How did you copy the patterns 10 years ago? What has changed?...
