I've read and heard of gesso on classes, in the chat room....what is it and how is it used? I haven't had the opportunity...I don't think.....of having used it or need to use it....so, what does it do? Is it necessary for acrylic painting?

Gesso  Way better than I can explain it. ;)

And it's not needed under acrylics, not if you have a ready to paint on canvas as you buy them in the art store, they have 2 or 3 layers of gesso on them already.

Thanks, Germa.   Soooo...if I put gesso over a dry, painted acrylic, can you repaint it? It's a sealer? "Hider"?
What do you use it for with acrylics? Is it to paint over?
I'm just curious as I hear people who have used it in conversations in chat and on the oil/acrylic lessons.
Thanks, again.

why would you put gesso over a dry acrylic painting?

Acrylic gesso is used for priming canvas - without it the paint would sink into the canvas.
It is also used for priming board and paper and provides a tooth for the paint to cling to.
It is not a good idea to gesso over a painting. Most canvases come pre-gessoed and some artists add more coats to get a smoother surface.

Note that when a canvas says triple-primed it means 1 coat on the back and 2 on the painting surface, not 3 on the painting surface.

All of the above!  And - you will hear about Gesso a lot in mixed media.  Artists use it on their paper or journal pages as a base to create on.  Since journalling is such a hot thing right now, Gesso seems to be talked about quite a bit.
