Black paint causes cracking and cupping of wood in direct sunlight. To determine if a painted surface is latex or alkyd, rub the paint with nailpolish remover. To estimate the number of coats of paint on a surface, measure the thickness of a paint chip with a micrometer. The solvents in alkyd primer will raise the nap of the drywall paper, requiring extra sanding before re-coating. Latex sealers do not raise the paper nap and can be top-coated with alkyd or latex.
