Hi Jim, Provided you didn’t apply a solvent based varnish to your original then it’s fine to apply gesso and go over it again. If a solvent based varnish was used it will need to be stripped off before any acrylic gesso is applied. If an acrylic varnish/medium was used you can apply gesso with no problems.
Due to the nature of oil paint, one cannot simply apply acrylic Gesso over the surface. It will not adhere properly and, over time, will peel away.
Similarly, how do you cover old paintings?
- Cover the old artwork. Paint over the original artwork with a few coats of white paint/primer.
- Mark the centers. Use a pencil to mark the center of the canvas and the center of each side of the canvas with small dots.
- Straightedge template.
- Transfer the pattern.
- Tape off the stripes, paint and repeat.
Similarly, you may ask, can you paint over a used canvas?
The key to reusing an old canvas is preparing your canvas properly. Your best bet is to lightly sand the painting, to even out the surface, then paint over the whole thing with primer. You DO NOT want to paint with acrylic over oil or oil over acrylic, because that is a recipe for flaking or peeling paint.
Can you paint over a store bought canvas?
The best way to deal with a pre-used canvas is to apply a gesso coating over whatever is printed or painted on the canvas. Then you have a fresh support that won’t be impacted by what’s underneath. If there’s any of finish over the printing, like a uv coating or protective gel, the gesso should cover that.
What is a substitute for gesso?
What are the alternatives to gesso? You can prime a canvas with acrylic mediums, clear gesso, or rabbit skin glue. If you work with acrylics, you can also paint directly on raw canvas without priming it first. Oil paints require a primer to protect the canvas from the linseed oil found in oil paints.
What is the difference between gesso and primer?
So “gesso” refers to the water based grounds, that is, the traditional hide glue/calcium carbonate or the modern acrylic polymer variety, while “primer” is the name reserved for an oil based ground for oil painting.
Is gesso really necessary?
Whether or not it is necessary to paint upon a surface primed with gesso depends upon which kind of paint you are creating with. If you are using acrylic paints you do not need to use gesso. It is absolutely necessary for oil painters to create some kind of barrier between their oil paints and the raw canvas material.
Can I use primer instead of gesso?

Do I need gesso for acrylic painting?
A common question regarding acrylic painting is if you need to use a gesso primer. Technically, you don’t. It provides you with a nice, slightly more absorbent surface to work on, especially if your working on board or raw canvas, but for a pre-primed canvas it’s unnecessary.
Is there clear gesso?

Can I use white paint instead of gesso?
Gesso is not only a better surface than white paint but also gives some texture to the surface. But what’s more important, if you don’t use gesso, the canvas will soak the painting and you will spend more paint.
What is gesso paint?
Gesso is an important art supply to get your canvas ready for painting. 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.
Do you need to prime canvas for acrylic paint?
If acrylics, then the answer is no, you don’t really have to prime the fabric in that case as the gesso that is used to prime canvases is actually an acrylic paint which serves to protect the fibers of the fabric and give paint a good surface for adhesion.
Can I layer acrylic paint?
