Just a simple facade project, a adobe chapel for the sinners in Borracho Its a leftover peice of 1/2" thick foam core, Precision Plastics door and round window, wood dowels and a couple of school “Build a Mission” detail parts, the walls are coated with Gesso and acrylic paints still needs a bit of weathering but it looks neat.
pretty kewl!
Neat.
What is Gesso?
Gesso is the Italian word for “Board chalk” (akin to the Greek word “gypsum”), and is a powdered form of the mineral calcium carbonate used in art. Gesso was traditionally mixed with animal glue, usually rabbit-skin glue, to use as an absorbent primer coat for panel painting with tempera paints. It is a permanent and brilliant white substrate, as long as it is used on wood or masonite. This mixture is rather brittle and susceptible to cracking, thus making it unsuitable for priming canvas. In Geology, Italian “Gesso” corresponds to the English “Gypsum”, as it is a calcium sulphate compound

Well, as every school boy knows:
"Rabbit skin glue has been the binder of choice for water gilding wood frames for about as long as there have been frames. The reasons are numerous but there are three very important factors. First, rabbit skin glue is strong. It is in fact one of the strongest adhesives know to man. When gilding wooden chair and table legs, gesso made with rabbit skin glue is used because it can take a kick and still live to tell about it. Rabbit skin glue has the unique ability to distribute pressure through out it’s structure when it receives pressure instead of cracking. This renders the materials it makes burnishable. Secondly, rabbit skin glue is hygroscopic, it reacts with moisture. The gesso it makes will react to climatic changes along with the wood insuring a durable bond. Third, rabbit skin glue reacts to heat. All mixtures made with rabbit skin glue must be applied to a surface warm. When diluted rabbit skin glue is blood temperature it is a thin liquid that can penetrate the wood surface. When a warm aqueous mixture is applied to a wood surface the fibers of the wood swell and open aiding the penetration of the glue into the surface creating a wonderful bond between the object and the finish.

Bruce,
Thank you! I had no clue (seriously)!
I wasn’t much of a school boy;)
Yea, what he said…
Also when applied with a broad brush can be textured and stippled like a stucco finish, not for outdoor finishes, strictly indoors, but then being an innie I can cheat on finishes alot more the outies.
