But don’t get away so fast because there are some exciting tips and tricks you can use in the painting projects. Stay tuned!
As mentioned above, it depends on many factors to tell how long a paint coat gets dry enough to cover a new one on it. Let’s take a tour to see how the elements affect the dry time between the layers.
How Many Factors Are There to Affect the Dry Time of the Paint?
Climate and Humidity
It is different when you do a painting project in a tropical climate zone versus in a temperate zone. The temperate zone is a perfect area for the painting work as the climate allows the paint coat to be dry within 1 to 4 hours. With this duration, you can finish painting the walls of a medium room no longer than 24 hours.
Moisture plays a vital role in drying things. The temperate area has low humidity in the air, so the paint layer gets dry very fast. On the contrary, it is tropical with a high humidity so it takes time for paint to be dry so early.
Humidity also affects the drying time of the paint like climate, but it is clearer to see. With moisture, we are talking about the condition of the air in the living environment. If your room has a high level of moisture, it’s best to wait for a couple of hours to touch them.
However, we are focusing on adding the second paint layer, so the first cover does not need to be thick. The dry time may vary from 6 to 12 hours. We will explain it thoroughly so that you can have a better insight on the subject.
Type of Paint You Use
Paint type is significant when you estimate the time for the paint to dry. There are four main types: latex paint, oil-based paint, chalk paint, and spray paint. You may guess which one has the shortest dry time – spray paint. Because spray paint has low density and allows the air to get inside and patch. In the ideal condition, it may take about an hour for you to recoat the wall using spray paint which is really fast and convenient.
Latex paint, which is also water-based paint, takes about 2 to 4 hours to dry in a suitable condition. You can apply this paint type with a roll or a brush, so the density and the moisture is at a high level. To make sure the paint is fully dry and ready to apply another coat, you may wait for at least 6 hours.
Oil-based paint is the most humid and moist paint as it has a high-gloss level. You will need patience and carefulness to apply this type of paint on the wall. Usually, it takes up to 24 hours for the oil-based paint to be ready for the second coat. The oil is the main factor which makes the dry time long like this.
Tips for oil paint: when first coating, you remember to roll a layer that is as thin as you can. A thin layer gets dry faster, while you eventually cover a new one over it, so you do not have to put a thick coat in the first place. The second tip is to choose a product with a low ratio of oil and a high amount of pigments. This product will help your work be done more quickly.

The Way You Paint
How do you cover the wall with paint? Do you use a brush, roller, or sprayer? The way you paint also affects the dry time of the product. If you apply a thick coat with a roller or a brush, it takes much time to get things dry. On the contrary, using a sprayer or covering with a soft layer will save time for waiting.
As mentioned before, the paint in a thin layer is in low density and contacts more with air and the environment around. The wind blows and dries the moisture in this layer very fast. A thick layer has much paint and a lot of humidity. Also, the high density of the content will lengthen the dry time.
Do I Really Need to Wait 4 Hours Between Coats of Paint?
According to the information above, the answer to the question is “yes, I do”. To ensure the best result for your project, you should wait enough time before applying the second coat of paint.
It is supposed in an ideal condition with an appropriate way of painting; the dry time of each paint type is as below:
- For latex paint: 2 – 4 hours
- For oil-based paint: 24 hours and more
- For spray paint: 1-2 hours
However, we have some tips to shorten and save more time for your projects. Let’s find out some ways to improve the results and decrease the dry time.
The Best Tips for Painting Between Coats
1 Keep the Paint Coat as thin as You can
As noted above, you will need a couple of paint coats, not just one, so the first coat does not need to be perfect. It’s highly advisable to be gentle and careful when using the roller to create a beautiful and even surface . Doing this will thin the paint lines, and the paint will be drying quicker, saving you a lot of time.
Gently roll the paint and spread evenly on the wall. Remember to make a thin layer and do not paint over the area, which is already done. You can also check how thin a cover is by seeing the color and gloss on the wall. If the color is not too deep and the wall is not shining or glossy, then the first coat is good.
2 Shorten the Dry Time
The main factor to keep the paint wet is the moisture. Reducing the ratio of moisture and you will see the result of your project sooner which will come in handy for big and fast pace projects.
You can use a fan, super fan to create wind blowing and drying the moisture. Using a high-capacity fan and putting it in the middle of the room can also increase the efficiency significantly. You should also go outside while waiting and enjoying the fresh air.
Remaining the humidity at a low level is an effective way, too. The environment with low humidity decreases the moisture in the paint and also keeps the room fresh and bright. For this issue, you can use a dehumidifier to absorb and control humidity in your room. This machine can work all day, so you can turn it on before starting your project.
Another way to reduce humidity is to use an air conditioner. Accordingly, this machine also has a function to absorb and dry out the moisture. It provides fresh air to the room and keeps the moisture at a low level.

Knowing proper ways to paint the wall will increase the quality significantly. Everyone wants a beautiful, bright, and uniform wall, but many of them do not know how to paint the right way. So how to apply a second perfect coat of paint?
You can start painting from anywhere as long as it is convenient for you, but remember to follow where you have painted. In this way, your paint lines are straight, even and you won’t miss any area. Paint in “W” or “M” shape as you do in first coat, do the “cut-in” near the doors, windows, and trims. Paint the areas in the right order you’ve planned, or you will paint three layers in one position.
Preparing a mix of paint before getting into the project is also very important. It helps you see the correct paint color so that there is no difference between the actual color on the wall and inside the gallon. Stir and mix the paint thoroughly before pouring it into a bucket. The paint used for the second coat must be in the same bucket with the one used for the first coat.
When finishing the first coat, you will need to preserve the tools such as paint tray, bucket, stick, brush, and roller. Use plastic to wrap the roller to avoid it from being threadbare. Cover the bucket of paint with a damp cloth to keep the moisture level inside.
You can also clean the brush or roller if you have to wait a day for the wall to get dry. Clean all the tools after each use so that the next time you need them they will be in their best state and ready to be used.
4 Patient! Patient! And Patient!
Patience is the key in any stage of the painting project. When you prepare, you need to get things ready and cover things carefully so that the cleaning process afterward will be much easier. When you are in the process, you need to cover the areas slowly and do not miss anywhere.
