100 year primers for your artwork?
Gesso vs. plain acrylic primer 

Mollecular Bond - 100 years - go Gesso
When done, don't forget to clear coat!


Don’t use house paint - ever – if you are serious about your artwork and want your work to last.

Practical folks recommend ordinary acrylic primer vs. the artist types recommend ‘gesso’.

Gesso on canvases gesso on board etc.
Gesso creates a surface that fills in the pores of your canvas, covers it smooth so when you paint you can just paint right over it. 

Raw canvas and many softer materials requires a “barrier” or the paint won’t handle properly, will sink in and eventually rot the canvas.

Gesso is a white or colored coating for the preparation of the surfaces to be painted (canvas, cardboard, paper, wood...). It dries quickly and has a light matt finish which improves the adhesion of the paint layers. ...

Gesso is an important art supply to get your canvas ready for painting. You can purchase gesso ready made from any art supply shop. Gesso is very similar to white acrylic paint, only thinner. It dries hard, making the surface more stiff. Gesso prepares (or "primes") the surface for painting, making the surface slightly textured and ready to accept acrylic paint. Without gesso, the paint would soak into the weave of the canvas.

History: “Real” Gesso (which means ‘gypsum’ in Italian), is primarily rabbit glue and gypsum. Modern “gesso” used today is a plastic polymer. Acrylic paint technically needs no “gesso”, but adheasion and having a smooth prepared surface is a plus. Oil and egg tempera paints should be used with their traditional gesso formulas, and not acrylic “gesso”. Acrylic “gesso” is too flexible for these paints.

Student paints are an inexpensive alternative. They have cheaper student Gesso. House paint is designed with very cheap pigments. House paint does not need to last much longer than a decade. Student paints have less pigment then their more expensive pro paints, and sometimes may have lower quality pigments, but any from a reputable manufacturer are designed with lightfastness and stability in mind and are better than home paints.

See how long it takes to get a board ready. using a Gesso Spray Gun it takes less than a minute and the surface will be smooth. We recommend at least a 2.0 tip set Gravity for small canvas and 2.5 Gravity for larger canvas.

Painting Gesso is a lot of work. See Video

If you don't spray and want a smooth surface brushing is even more work. To make a really smooth coat, use sandpaper to gently sand in between each layer. Make sure the surface is completely dry before attempting this!
Using a quality spray gun sanding is unnecessary unless you want a glass like surface then just a little sanding will do.

Why not use spray cans? by the time you add up your cans you might of well invest is good equipment and sprayguns work better becuase you can use thicker Gesso formulations and still get control of your surface quality.

Do i need a big compressor? No. Low CFM Spray Guns Operate on smaller compressors. Plus For small canvas you can use a 4CFM compressor, larger canvases a 5 or 6 cfm will work well. Here is a nice one from Costco

 

How many layers of gesso will you need to properly prime your canvas? It depends on your personal preference. Try a canvas with one coat of gesso, then another one with two, and maybe even one with three. Note the difference in how the canvas feels and in how it accepts the paint. It's generally a good idea to coat the canvas at least twice, to ensure that you've covered the entire surface.



How about a realy cheap gun? Gesso is thicker than most material. most spray guns sold at do it yourself stores are not designed to handle this type of material. or they will require more air than a 110v compresso can run on.
