Do Not Re-touch Drying Paint

What happens here

A critical rule for achieving a flawless finish when brushing or rolling is to apply the paint, ensure it's laid out correctly and evenly, and then absolutely *do not touch it again until it is completely dry*. The painter stresses that if you miss a spot or notice an imperfection while the paint is still wet or tacky, wait until it fully dries before going back to hit that spot. Re-working paint that has begun to dry will almost certainly result in visible roping, brush strokes, or other undesirable textures. Paint that has started to coagulate or become sticky will not smooth out properly.

Goal: Avoid imperfections by letting paint dry completely before any touch-ups.
