Paint Problems and Causes Guide

Peeling, bubbling, cracking, chalking, mildew, stains and uneven sheen: what causes each and how to fix them properly.

Most paint problems have a cause beneath the paint, not in the can. Peeling often means moisture, dirt or a glossy surface that never gripped. Bubbling can come from heat, moisture or painting over a damp or dirty surface. Cracking and alligatoring happen when layers are too thick or the surface moves. Chalking is a powdery film on older exterior paint that signals aging. Mildew grows in humid, shaded areas, and stains bleed through when the source is not sealed. Uneven sheen, called flashing, comes from patchy preparation or roller technique.

Fixing the symptom without the cause brings the problem back. Peeling paint needs scraping, sanding, spot priming and sometimes a moisture fix before recoating. Mildew needs cleaning and good ventilation or sunlight. Water stains need the leak repaired and a stain-blocking primer. Cracked or alligatored paint may need stripping. In Nashville, humidity and sun combine to stress exterior paint, so a quick inspection each year, with cleaning and caulking, can prevent larger repairs. When the cause is structural or involves a leak, we say so plainly.

Questions

Paint Problems and Causes FAQ

Why is my exterior paint peeling?

Moisture, poor prep or a glossy base are the usual causes. We scrape, prime and repaint after addressing the cause.

Is mildew harmful to paint?

It can stain and degrade paint. Cleaning and addressing humidity help prevent it.

Can I paint over a stain?

Not directly. Use a stain-blocking primer first, and fix the source of the stain.
