Figuring out how long to wait between coats of paint depends on several factors, like the type of paint used, its application, the temperature and humidity, and ventilation in the room. If you're rushing to finish your paint job in one day with multiple coats, knowing the wait time between layers is essential.
How Long Should You Wait Between Coats of Paint?
It is typically safe to apply a second coat after four hours for latex paint and 24 hours for oil-based paint. Latex paint is dry to the touch in about one hour, while oil-based paint is dry to the touch in about six to eight hours.
Why Paint Recoat Time Matters
One of the surest ways to ruin paint is to apply subsequent coats before paint recoat times have elapsed. When you apply later paint coats too soon, you risk:
- Streaks
- Skinned paint peeling off
- Bubbles
- Tiny pits
- Large pockmarks
Tips
Damaged paint cannot be repaired while the paint is wet. Wait until the paint has dried, then sand it or apply a smoothing surface treatment. Finish by painting.
What Dry, Recoat, and Cure Mean
Each coat of paint must dry before the next coat is applied. There are three distinct time frames with painting: dry time, recoat time, and cure time.
- Paint dry time, or dry to the touch, is the time it takes for wet paint to become tack-free and dry to light contact.
- Paint recoat time is the time it takes for paint to be thoroughly ready for another layer of paint.
- Paint cure time is the time it takes for paint to fully harden so it becomes washable and more touchable—a process that can take weeks, depending on the season and climate.
What Affects Recoat Time
- Time: All paints require at least 30 minutes, even in ideal conditions.
- Type of paint: Water-based paints dry faster than oil-based paints.
- Temperature: 72 degrees F is optimal.
- Humidity: Maintain a humidity level of 40 to 50% for best paint-drying conditions.

Recoat Time for Water-Based Latex Paint
The average recoat time for water-based latex paint is four hours. Water-based paint should be dry to the touch in about one hour.
Paint binders hold the color pigments together. Flat paints have fewer binders than glossy paints. Binders in these formulations also translate into longer drying times.
The flatter the paint sheen, the faster it will dry. Glossy paints take the longest amount of time to dry. Eggshell and semi-gloss paints, since they are in the middle of the paint sheen scale, represent average paint drying times.
| Paint Types | Drying Time | Recoat Time |
| Flat or matte paint | 30 minutes to 1 hour | 1 to 2 hours |
| Eggshell paint | 1 hour | 2 hours |
| Semi-gloss paint | 1 hour | 2 hours |
| Glossy paint | 1 to 1-1/2 hours | 2 to 2-1/2 hours |
| Primer | 30 minutes | 1 hour |
Recoat Time for Oil-Based Paint
The average recoat time for oil-based paint is 24 hours. The paint should be dry to the touch in six to eight hours.
Oil-based paint is more durable and takes longer to dry than water-based paint. Water-based paints dry considerably faster than oil-based paints because the water evaporates to let the paint dry. Oil-based paints contain no water.
Though oil-based paint may feel dry after only a few hours, it's best to wait a full 24 hours or more before applying additional coats.
Factors That Affect Drying Times
Even if you're painting indoors, the temperature of the room and the surface you're painting affect drying and recoat times. Always apply paint within the temperature parameters specified by the paint manufacturer.
Temperature
Most water-based paints will optimally dry in a room at about 72 degrees F with average humidity. Oil-based paints will dry best in room temperatures above 50 degrees F but under 90 degrees.
Humidity
Colder temperatures and excess humidity slow the drying time for water-based paints since the paint's water needs to evaporate to dry.
Ventilation
Circulating the air with a fan on low quickens paint drying times. Letting in fresh air through open windows helps the paint-drying process unless it's too cold, hot, or humid outside.
Tip
Oil-based paint oxidizes and hardens, which differs from water-based paint, which dries via water evaporation. Add a siccative, an oil-drying agent containing linseed oils and alkyd resins to accelerate the hardening process of oil-based paint. Japan drier is the generic term for these types of catalysts.
Application Methods
Whether sprayed, rolled, or brushed, the mode of paint delivery affects the drying time between coats.
- Sprayed paint applies thinly and evenly, which makes it dry to the touch in as little as 30 minutes and ready for another coat in as little as one hour.
- Rolled-on paint or using a paintbrush are heavier than spray paint and take the longest time to dry between coats. The use of different types of rollers may also slightly affect drying times. Always wait for the complete drying and recoat times before applying the next coat.
FAQ
How long should paint dry before putting furniture back?
Latex interior wall paint should dry for at least one hour before putting the furniture back. One hour is the dry-to-the-touch time recommended by most paint manufacturers.
How do you make paint dry faster?
Increasing the temperature and improving the airflow can make the paint dry faster. Add a space heater to a room to help the paint dry faster. Placing a room fan in a door or window will increase airflow and speed up the paint-drying process.
How long to let primer dry before painting?
Primer should dry for about one hour before applying paint. Primer may dry to the touch in about 30 minutes. But let another half-hour elapse before applying paint or another coat of primer.
What will happen if a second coat of paint is applied too soon?
If you paint a second coat while the first coat is still wet, liquid, and pliable, you risk creating pulls and streaks in the soft, gel-like material. Bubbles and pits form. Everything below the topmost layer of paint is still wet, so rolling or brushing the paint rips up the dry skin and mixes it in with the wet paint.
Can you wait too long between two coats of paint?
Wait as long as possible between two coats of paint—up to a point. It's OK to wait seven days to add a second coat of paint. However, if you wait too long, factors such as dust, UV rays, and more can change the color of the paint and impact the look if you add a second coat.
How Much Does It Cost to Paint a Room?
