Before applying your best color paint on your interior walls, you often recommend applying a suitable primer. But it also involves taking into account how long it will take for the primer to dry so you can start painting. That is why it is usually better to use a quick-drying primer and get started painting right away.
On wood, most latex primers take 30 minutes to an hour to dry to the touch. Nevertheless, most primers, on the other hand, require 3 hours to completely dry before painting. It can take up to eight hours for oil primers to dry. Generally, the majority of manufacturers suggest waiting at least an hour before painting over the primer coat.
However, the approximate drying time is determined by;
- The type of primer you use.
- The room temperature
- Humidity level
- The painting’s target surface
If the temperature is warmer and there isn’t a lot of moisture in the air, the primer would therefore dry faster.
It is vital that the primer completely dries before beginning your paint job. Some factors to consider that influence the dry time of primers include:
Primers that Dries Quick
- It dries to the touch in 30 minutes at a room temperature of 77°F (25°C) With 50% relative humidity.
- In addition, you can recoat or top coat in one hour with latex or oil-based paint.
Be aware that application in low-temperature, humid, or poorly ventilated places will alter the amount of time it takes for anything to dry.

- At a room temperature of 70-80°F (21-27ºC) and 50% Relative Humidity, it dries to touch in 5 minutes
- And can be top-coated in 30 minutes with latex or oil-based paints.
Before using strong solvent-based topcoats, let the primer dry for at least one night for the best results.
- At 77°F (25°C) and 50% humidity it Dries to the touch in 30 minutes
- Then you can recoat or topcoat after 1 hour
Primers that take longer to dry
- It Dries in 60 minutes
- You can recoat in 2 hours
To achieve the desired results, allow the primer to dry completely before painting. Depending on the temperature and humidity, this could take up to 3 hours.
- It takes 30 minutes to dry to the touch at 70°F (21°C) and 50% relative humidity, an hour to handle, an hour to recoat
It is important to note that: For maximum protection, apply topcoat within 72 hours of application and wait at least 7 days for full adherence and hardness to develop.
Types of primers and its overall drying time
primer type | Drying time |
Oil-based primer | They take between 30 minutes to 4 hours to dry |
shellac | Takes between 30 and 60 minutes |
Self-priming paint | Takes an hour to dry |
Latex primer | They usually take less than 1 hour |
Note Better: The overall drying time is widely determined by the different brands and products, as well as other aspects. As a result, always follow the instructions on the container and consider the circumstances that will affect drying time.
Factors Affecting the Time It Takes for Primer to Dry
Below are factors that determine the drying time of primers.
1. Temperature
The ideal temperature for a primer to dry is about 25 degrees Celsius, or 77 degrees Fahrenheit. Lower temperatures increase the drying time of primers. Therefore, the temperature must be maintained at or close to the recommended level.
2. Humidity
Like temperature, humidity should also be maintained at a specific desired value. When the humidity is high, the primer is exposed to a lot of water vapor, which means the time for the primer to dry is longer as the water content takes longer to evaporate.
Lower humidity, on the other hand, reduces drying time. The ideal relative humidity level is frequently around 15%. You can use a dehumidifier to control humidity and achieve this level.
3. The type of primer that is being used
Different primers from different manufacturers have varying drying times. If the manufacturer uses oil instead of water, the primer takes longer to dry. Therefore, water-based primers take less time to dry than oil-based ones, which is why they’re a good choice if you want your paint job finished quickly.
4. Primer application technique
To achieve faster drying times, apply your primer with a paint sprayer, which results in a thinner coat. However, applying a primer using a brush results in a thicker coat that takes relatively longer to dry.
5. Whether it’s an indoor or outdoor project
When the primer application is carried out outside, you have less control of the conditions. Mostly, the drying time is at the mercy of the elements. When the humidity is high, the primer will take longer to dry. Similarly, a wet day will see longer dry times. Therefore, when applying a primer outside the house, choosing a day with favorable conditions is essential to ensure fast drying.
6. Ventilation status
The ventilation in your room can lower and increase the drying time of your primer. For fast drying times, ensure the windows are open and use a dehumidifier, or fans, to increase air circulation, which gets rid of any humidity and increases the drying rate. Additionally, dust and particles in the air should be removed as they attach to the primer when drying.
Tips on how to make primer dry faster
To help speed up drying times, follow these simple tips.
1. Use a primer that dries quickly.
A fast-drying primer can save you a lot of time and hassle, but not all primers are created equal. Depending on your project and how much time you have, there are different things you should look for in a primer.
If time is of the essence, you’ll want to use an epoxy or polymer-modified acrylic latex primer that dries quickly. These primers aren’t ideal for every project—for example, they can crack when applied over oil-based paint—but they get color down quickly if you don’t have time to experiment with other options.
2. Make use of a hairdryer
Using a hairdryer set on high will help accelerate how quickly your primer dries. This way, you’ll spend less time waiting around and get to painting sooner. The result is that you save time and still have beautiful walls or cabinets.
3. Improve air circulation
The key to a quick-drying primer is allowing plenty of airflow. Be sure paint won’t be touching any surfaces that won’t be painted, as that will slow drying time. If you can, roll or brush your primer coat on a day with good airflow so it dries quickly. And remember, the better ventilation you have in your workspace, the quicker it will dry.
Improving ventilation will not only make you feel better while you work, but it can also help prevent overspray from settling on objects and furniture around your home. While you paint, keep doors and windows open as much as possible and place fans in nearby rooms or open windows so fresh air circulates throughout your home.
4. Apply a thin coat of primer.
A light coat of primer will typically dry in an hour, whereas a thick coat can take up to 24 hours. Applying thinner coats of primer is always recommended if you want to shorten the drying time between applications.
Note better As with any painting project, it’s essential to be aware of conditions (weather and humidity) and adjust your timeline accordingly.
5. Maintain a low humidity level.
The paint you’re using is likely intended for indoor use and won’t hold up well in a humid environment. Excessive humidity can also have adverse effects on your health; avoid high-humidity locations if possible, and do what you can to keep humidity levels low. In some cases, it may be necessary to use a humidifier in combination with air conditioning, but there are risks involved even then.
6. Be aware of weather conditions
Weather conditions, such as temperature and humidity, can affect how long it takes your primer to dry. If it’s cold or humid out (especially both), you may need to allow extra time for your primer to dry before painting; if it’s hot outside, you may be able to paint sooner. If painting outside, consider choosing a day with little wind and good weather
Think about what conditions are forecasted in your area on days you plan on painting, and plan accordingly.
Frequently Asked Questions
What Happens if You Paint Over Primer Too Soon before it dries?
Applying primer creates a barrier between your walls and any paint that might chip off or peel in future years. It can turn lumpy and peel off if you don’t give your primer enough time to dry before applying paint.
These are liquefied primers because they become so soft from moisture in the air that they liquefy.
There are two ways to prevent that from happening, and both involve increasing ventilation in your workspace. First, set up a fan or install an air conditioner if you have one nearby; either will help decrease humidity levels and increase drying time.
Second, use a spray-on primer instead of a brush-on one—the thick coating will ensure even coverage and no room for error on your part. In addition to drying issues, other potential problems include creating bubbles on the surface of your paint or causing streaks in its finish when painted over too soon.
What will happen If you skip a step in painting prep and try to paint over bare drywall
Nothing happens if you skip a step in painting prep and try to paint over bare drywall. You’ll be disappointed when your nice, new coat of paint doesn’t stick, but at least you won’t damage your walls in any way.
However, if you skip priming and go straight for a topcoat without letting that primer dry entirely first, there’s a chance that some of your new paint will peel off with it.
Although relatively rare, it does happen! Remember that a good primer takes longer to dry than just about anything else on your wall—but once it is up to snuff, you’re ready for whatever comes next. Now get out there and repaint something!
Conclusions
In conclusion, there are good options for the type of primer one would require depending on the wood project at hand, even when the consideration is the period necessary for the primer to dry to apply paint.
The drying time of a primer also depends on other factors such as humidity or the type of wood. Therefore, it is advisable to maintain the other conditions as suitable as possible to achieve swift drying.
