Don’t laugh..what is gesso

If you paint the gesso with acrylic you loose the whole purpose of using a gesso surface in the first place. You do get black gesso that can be used instead.
Right you are! I know there are black and other colored Gessos out there. Was just a suggestion for making use of what Joe had on hand.
 
I watched a guy use automotive heavy primer to prep a cloth canvas with , For MDF board I find it faster to just use primer like I would for a metal panel
 
I’m going to prime some mdf tomorrow at work. I must spray 5 gallons of that stuff a day...lol

Gesso is more absorbent than Primer and it will seize the canvas. On MDF you don’t need the Seizing (shrinkage) property.

On claybord they used rabbit skin glue to accomplish the same with canvas but again with MDF you don’t need that. That is why we have been using PVA glue instead.
