Q: How are the ingredients different between the casein gesso and casein bases? Is the casein gesso more opaque?
A: The three different products only differ in the amount of White Pigment that is added to the formula.
1. Deep Tint Base: contains no white pigment.
2. Light Tint Base: contains some white pigment to work in conjunction with any pigment that gets added to the base, in order to brighten the color.
3. Casein Gesso: contains the maximum amount of white pigment, for maximum brightness and coverage (opacity).
Q: I use clear acrylic Gesso for making sanded pastel paper/boards as it has very fine grit, does this product have any fine grit qualities?
A: No, this gesso does not have a gritty quality. You could take our Casein Deep Tint Base and add some sand or pumice to achieve a gritty texture.
Q: If used on stretched linen or canvas, could casein gesso go directly on the stretched fabric (right now I am using traditional gesso -- I like the Utrecht brand which has a very soft, smooth finish -- over a ground of rabbit skin glue)?
A: It would be best to size the canvas/linen first with rabbit skin glue.
Q: how much is gallon of casein Gesso?
A: The gallon is $85.00. If you look on the product page, there is a toggle bar where you can select the size. Once you have selected the gallon size, then the price will automatically update and you add the item to your shopping cart.
Q: Would casein gesso be too rigid for stretched canvas?
A: The Casein Gesso works on canvas that has been stretched taut.
Q: Is there a lead white version?
A: No, there is no lead version. Our Silverpoint Ground would probably be closest in consistency. You could also add some lead white pigment to our casein base, which is available in the Milk Paint section.
Q: Where can i find a tutorial on how to use casein gesso to prepare an icon board?
A: Any panel needs to be prepared in the same manner as with traditional gesso. The panel needs to be sealed on all sides with either rabbit skin glue, shellac or PVA. For a full tutorial on panel prep, please visit our bole page:

Q: The piece I’m working on has an existing coating described as an acrylic based, burnish sealer. Can I apply the gesso over this after sanding?
A: Yes, once you have created some tooth on the surface with sanding, you can apply the Casein Gesso over the existing panel.
Q: How long does the casein gesso last after opening the jar?
A: Ideally the gesso should be used within 2-3 months, but can stored in a sealed jar for up to a year.
Q: I am using your milk paint before applying size for leafing.
on wood panels.
Should I be applying gesso to the wood first?
The work is for indoor use.
i am painting on the leaf with "oils" that can be cleaned with water.
by Gamisol. The label does not say alkaloid. It says oils.
A: You can apply the Casein Gesso as a substrate for the Milk Paint, but it is not necessary. We do recommend sealing the panel with something like shellac first, before applying either the gesso or the milk paint. Once you have applied the milk paint, you may want to buff the dried surface with a cloth, so that the paint is less absorbent and thereby better suited to hold the gold size for your leaf.
Q: Hi there,
I am looking for a more absorbent gesso to use on wood panel prior to applying gouache. I've had issues with gouache lifting very easily from acrylic gesso (it slides right off, and I can't layer it at all or build up opacity), and I also prefer to seal my panels with cold wax which doesn't adhere to acrylic. I am wondering if gouache will adhere well to this gesso? Also, does this gesso require some kind of sizing prior to application to protect the wood? If so, do you have a recommendation? Finally, do you make it in a "clear" gesso? Thanks so much!
A: For your project we would recommend our Casein Absorbent Chalk Gesso and Silverpoint Ground. It is slightly more absorbent than the standard casein gesso and will make a great substrate for your Gouache Paint. Once you have applied your gouache paint, you can seal the painting with cold wax, as long as you let ground cure for 3-4 days after application. We do recommend sealing your wood panel with shellac, before applying the ground.
Q: I see no reason why this product couldn't be used to actually paint in Casein, as an under-painting for oils. It seems that powdered pigments and/or watercolors could be
mixed with it and it would flow similar to Borax Casein. What do you think?
