Can a cracked oil painting be repaired?
Repair cracked oil paintings. Repairing cracked paintings restores them to their original state. The process, which can be done at home, involves strengthening the surface with a beeswax and damar resin mixture that prevents further deterioration and glues the paint to the stronger base.

If the lower paint layers contain more linseed oil than paint applied on top, the top layers will tend to dry sooner. This may cause cracks to develop.

Why is my painting cracking?
Cracking occurs in acrylic paint pours when the top layer of paint dries faster than the underlying layer. As the bottom layer dries, it pulls at the semi-hardened skin on top and when the force is too much, a crack is created. Newly formed cracks will continue to widen until the paint is fully dried.
