In art, an underpainting is an initial layer of paint applied to a ground, which serves as a base for subsequent layers of paint. Underpaintings are often monochromatic and help to define colour values for later painting.
Alligatoring is patterned cracking in the surface of the paint film that resembles the regular scales of an alligator.pplying the topcoat before the undercoat is dry may also cause alligatoring. Alternatively, the natural aging of oil-based paints as temperatures fluctuate causes constant expansion and contraction that can result in a loss of paint film elasticity.
