Why is my paint leaving streaks?

Author: scraper  |  Last update: Wednesday, August 12, 2026

Paint is usually streaky because of uneven application, a nearly dry roller, or trying to stretch a single coat too far. Common culprits include pressing too hard (squeezing out the paint), using low-quality tools, or brushing/rolling over paint that has already begun to dry.

How do you fix streaky paint?

To fix streaky paint, lightly sand the dried surface with 220-grit sandpaper to remove surface ridges, wipe the wall completely clean of dust, and apply one or two thin, even coats of high-quality paint.
