How To Fix Cracked Acrylic Paint On Canvas: Methods

To fix cracked acrylic paint on canvas, there are several methods that can be used.

One method is to use sandpaper over the cracks with circular motions. Depending on how big your painting is and how many cracks you have, this step could take some time (source: Acrylic Painting School).

Another method is to apply a white acrylic paint that has been thinned with a little bit of water over the cracks (source: Quora).

You could also try sanding the affected areas and overpainting with oil paint using mineral sprit acrylic (MSA) varnish as a medium (source: WetCanvas).
