- Check the weather forecast before starting the job. Rain or high wind can cut a day of painting short and ruin what's already been applied. Exterior latex is fast drying, but it still needs time to dry before it gets hit by rain. Oil-based paint definitely needs curing time; check the manufacturer's recommendations. Paint when temperatures are above 50 degrees Fahrenheit and below 85 degrees Fahrenheit. Heavy rain or high humidity on a newly painted uncured surface can cause blistering.
- Set the ladder up on flat ground. For more about ladder safety, see our Ladder and Scaffolding Buying Guide.

Paint on homes built before 1978 may contain lead. Check with your local health department or the Environmental Protection Agency if you have questions or concerns.
