Oil-based enamel usually takes 24 hours before it is dry to the touch under normal drying conditions. Normal oil-based paint drying conditions include low humidity and air temperatures above 21.1 degrees C. Many painters open doors and windows and then set a floor fan to blow the air around to help speed up the process. Adding a paint drying additive is the quickest way to speed up the drying process without adversely affecting the finished product. Darker pigmented paints dry faster with the use of a paint drying additive.
- Skill level:
Things you need
- 1/2 cup measuring cup
- Paint drying additive for oil-based paint
- Mixing stick
- 1 gallon of oil-based paint
- Stir stick
- Floor fan
Mix 1/2 cup of paint drying additive per 1 gallon of oil-based paint, and stir it for several minutes using a stir stick. Mix the additive into the paint before the paint is applied to the painting surface.
Open all doors and windows. Set a circular floor fan up, and point it away from the surface to be painted. This will ensure the warmer air above the surface mixes with the cooler air near the surface.
Check a thermometer to ensure the temperature is above 21.1 degrees Celsius. Apply the oil-based paint to the surface.
Tips and warnings
- Air should never be blown directly at drying oil-based paint, because the upper surface will dry faster than the lower surface and cracking may occur.
- Always wear a paint respirator when working with oil-based paints to protect your lungs from harmful vapours.
