[06] Gesso Instructions

TRADITIONAL GESSO Proportions

POWDER:

  • 1 part calcium carbonate (aka marble dust, limestone or whiting)
  • 2 parts calcium sulfate (aka gypsum or pottery plaster)

GLUE:

  • 6 parts water
  • 1 part rabbit skin or animal hyde glue (approximately, but follow proportions on your package)

To cover 10 medium boards, I use this formula:

  • 3 tablespoons powdered rabbit skin glue
  • 2 cups water

Mix glue and water and let  combine over low, indirect heat.  Apply a coat of glue to boards and let dry.  Remove all but one cup of glue from heat and store for later use.  In remaining cup of glue, sift in:

  • 2 cups POWDER (see above)

Once powder settles, gently stir. You’re looking for a watery consistency if you plan to apply in many coats with sanding in between.  Pancake consistency if you want one coat.  But, bubbles may be a problem.  Adjust consistency using reserve glue stock if needed.  Be cautious to replenish water if it significantly steams away.

I have a 10-board gesso kit available in the online store.

NOTE:  Before applying gesso to your board, seal all sides of the board with a coat of the hyde glue mixture.  This is referred to as “sizing” and will help control moisture absorption.  This bit is left out of the video.

  1. I watched your program for the first time tonight. I was wondering where you buy the animal hyde glue, calcium carbonate and calcium sulfate? Thanks.


    • Kathleen, sorry, I missed this comment! The animal hyde glue or rabbit skin glue can be found in most high-end art supply stores online. I purchased my last batch at uTrecht. I also sell it in my online shop http://www.delgadoarts.bigcartel.com/product/1lb-rabbit-skin-glue 1lb/$12.95+shipping. The calcium carbonate & calcium sulfate are much harder to find in smaller quantities. I buy a 50lb bag once ever couple of years from our local pottery supplies store, New Mexico Clay http://nmclay.com/ .
