Why Paint Jobs Fail

CRACKING AND SCALING:

This is a serious paint failure and is usually caused by build-up of too many coats on a surface, or by applying paint too thickly. The surface splits and curls back due to a hard surface and softness underneath. This does not occur if the proper primer and finish coat are applied evenly and the primer is given enough time to become hard and firm before finishing.

When scaling is bad, all old paint should be removed before repainting.
