Things You'll Need:
- Fan
- Japan dryer
-
Step 1
Check the humidity level before you start painting. Ideal humidity for drying enamel or any other paint is between 60 percent and 70 percent. Paint might take an extremely long time to dry when the humidity is higher than 90 percent.
-
Step 2
Use a dehumidifier or turn on the heat or air conditioning to help speed enamel drying time. If you are using a lot of paint, the evaporating, drying paint will raise the humidity levels higher.
-
Step 3
Pay attention to the weather forecast, and don't paint outside if rain is expected within 12 hours.
-
Step 4
Paint when the temperature is above 60 degrees Fahrenheit. Avoid painting in direct sunlight or in dry temperatures higher than 85 degrees; this can make the paint dry too quickly and cause blisters in the paint.
-
Step 5
Open windows and use a fan to create air movement, which speeds paint drying time by evaporating the moisture from the paint film.
-
Step 6
Apply paint in two even coats instead of trying to paint one very heavy coat. A heavy film of enamel paint will dry much slower.
-
Step 7
Add 2 to 4 ounces of Japan Dryer (available at most paint and craft supply stores) to oil-based enamel. This can reduce normal drying time by half if the temperature and humidity is also conducive to speedy drying.
