It's okay to paint acrylic over a varnished acrylic painting in small moderation - for instance, if you need to do minor touch-ups here and there. All in all, as long as you are only touching up small areas with acrylic paint, then it is perfectly fine to paint over a varnish acrylic painting.
Lightly sand all the wood trim using a 220 grit sandpaper. This should help break up the varnish and give the primer a solid base to adhere to. Vacuum up as much of the dust from sanding as possible. Then, wipe down each surface with a tack cloth to ensure no dust was left behind.
Annie Sloan Wall Paint can be used on previously varnished or gloss-painted surfaces, but it will not have the same adhesion as Chalk Paint®. Chalk paint adheres to furniture beautifully without the use of primer and (usually) no sanding. A quick cleaning is typically all you need.
Starting in a corner of the painting, dip a lint free cloth into the turpentine and gently rub the surface of the painting. The varnish should come off on the cloth – but remember to keep a close eye on the cloth and stop if you see colour coming off.

How do you remove water based varnish?
- Pour equal parts of lacquer thinner and denatured alcohol into a small empty paint can.
- If the finish comes off easily, you can remove the entire finish with the alcohol or thinner; paint and varnish remover isn't necessary.
Apply varnish remover to a cotton ball, cotton swab or soft cloth. Gently wipe down the wood in small sections to remove the original varnish. Some paints have a varnish applied to them to protect the paint over time. Eventually, the varnish starts to break down, which results in yellowing of the paint.
All you need to do is start with 150-grit sandpaper and sand the entire surface. Once you've done that, move onto 220-grit sandpaper and repeat. This should remove the varnish. An orbital sander will make this job much easier and quicker if you're removing varnish from a flat surface.

White is the worst colour on which to start painting.
In acrylic and oil painting, white is the highlight colour. It is the brightest, purest colour you will put on your canvas, and we generally save our pure white for the very last step to add that pop of brightness.- 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.
