Winter can be harsh on leftover paint. Many homeowners store paint in the garage or shed without realizing those cold temperatures can ruin it.
Why Cold Temperatures Are a Problem
Latex paint is mostly water. When the temperature drops to freezing, the water inside begins to separate from the rest of the contents in the can. Once that happens, the paint may not mix back together the right way. Oil-based paint handles cold weather a little better, but it can still break down when temperatures fluctuate.
Common Storage Mistake
Garages, sheds, and outdoor closets often get below freezing at night. Even one freeze can cause:
- Lumps
- A grainy texture
- A sour smell
- A paint film that will not smooth out
Paint that freezes more than once is rarely usable again.
Better Places to Store Paint
The goal is steady, warm temperatures. Good spots include:
- A hallway closet
- A heated utility room
- A basement shelf (off the floor)
Aim for an indoor area with a comfortable, stable temperature.
How to Tell if the Paint Is Still Good – Good paint will:
- Mix easily
- Look smooth
- Smell normal
If it stays chunky or smells “off,” it’s time for a replacement. Using damaged paint can lead to peeling or uneven results.
A Simple Rule: If you’re not sure the paint survived winter, it’s usually safer—and cheaper in the long run— to replace it or call a professional for advice before starting a project.
