What is the difference between latex and oil-based paint?
Short answer
Latex (water-based acrylic) paint dries fast, cleans up with water, has low odor, stays flexible and resists yellowing. Oil-based (alkyd) paint dries slowly into a harder, smoother film but yellows over time, needs mineral spirits for cleanup, and has strong fumes. Today latex is the right choice for most walls and exteriors.When latex wins
- Interior walls and ceilings
- Exterior siding and trim (flexes with temperature swings)
- Anything you want to recoat the same day
When oil or an oil-like finish still makes sense
- Stain-blocking primers over water stains, smoke and knots
- Some high-wear trim, doors and cabinets, though waterborne alkyd enamels now give a similar hard finish with easy cleanup
- Over existing oil paint, if you'd rather not use a bonding primer
