Questions and Answers
This Casein Gesso was formulated by the Sinopia Test Kitchen and is manufactured in house. This versatile chalk ground is ready to use directly out of the jar at room temperature. Apply with a brush or roller onto panels, canvas, paper or any sculpture. Apply in at least two coats. Allow surface to dry overnight before sanding. This primer is the ideal surface for laying down bole for watergilding or painting in media that requires an absorbent ground, such as: encaustic, egg tempera, borax casein and watercolor/gouache. Once applied and cured, the casein gesso forms a permanent water insoluble working ground.
Q:
I applied two coats and let it dry for 24 hours. The third coat softened the previous two. Brushing it on created bare spots where all the gesso was pulled off the substrate. The gesso settles and filled in again, but I wonder if coats must cure completely before applying more? (I thinned it just enough to allow brushing.)

A:
It sounds like you applied more layers too early, before the first two could cure. After two layers, you should wait 2-3 days, before applying more layers or sanding.

Q:
After 48 hrs after application on hardboard it still comes off. Am I doing something wrong?
Asked by:
Kay Ara
- 8/7/2022
A:
Applying any type of paint onto hardboard can potentially pose problems, because the surface is either too slick, or the glues that hold the particles together can offgas and slow or stop the drying and/or curing process. It would be best to treat the surface first with a layer of shellac, in order to give the surface tooth and to prevent any chemicals from leeching to the surface.

Q:
I’m hoping to try all 3 of your gessos (black chalk, chalk, & casein) on MDF board that’s been sealed with GAC100. I’m wondering how much I’d need to cover panels that are 18x24 & 24x30 inches? Ideally I’d get the 4oz size for all 3 to try them, but would that be enough to cover a smaller 18x24 panel?
Asked by:
Kiara
- 2/24/2024
A:
We recommend going up to the pint quantity for the mentioned panel sizes, since all of the grounds require 2-3 coats.
