How Long Does It Take to Paint a Room?

Last updated on May 8, 2022

In short, it takes 3 days to paint an average room from start to finish. Read on to find out how we’ve come up with this answer.

When you want to paint a room, you have the option of doing the job yourself or bringing in a professional. Whatever decision you make, you probably want to know how long does it take to paint a room. This choice is important because it will determine when you can use the room again.

This is often a rush job, as many people decide to renovate while still living inside the house. You have to remove the furniture and then put it back in place. Painting is then a disturbing period, which will last more or less long. However, the drying time between two coats and the final drying time varies depending on the type of paint and the color chosen. For example, it will take longer if it is oil-based paint than quick-drying wall paint.

A part is considered to receive two coats of paint in a standard estimate, but this is not always the case.

So how long does it take to paint a room?

You will see that it is not easy to answer this question.

Indeed, before embarking on this renovation process, do you know how many people you will solicit? What process are you going to use? What is the type of paint? The number of layers? The surface of the room?

It is all of these factors that will determine the time required to paint. 

It takes an average of three working days to paint a room; this takes into account the drying time and the room’s preparation.

The Surface of the Part to Be Painted

The main factor to consider when estimating the approximate time to paint a room is the room’s size. Indeed, if you repaint an average size of 9.29m², the paint drying time is shorter than for a room twice as large.

The number of pieces you paint is also a factor, but not only. If you have one room and small painting projects in that room, it might take the same time as three equally sized rooms.

Consider that depending on the paint used. A standard 13.38m² room will require a paint drying time of approximately six hours between coats. Plus, windows, doors, baseboards, and crown moldings will also add time.

Estimation of the Complexity of the Work

If you’re tackling a custom painting project, it can’t be compared to a simple paint job. The job is not the same, whether it is a simple large, flat surface or more complex painting jobs. It is very important to estimate the drying times to know how long this work will last.

Look at what needs to be done for the preparation phase before being repainted. Whether the ceilings or walls need to be repaired or cleaned first. This would add additional time to determine the time needed to paint the room.

Tray ceilings, vaulted ceilings, or coffered ceilings are also a time consuming and expensive painting task.

You will find that the preparation and cleanup take longer than the actual paint job in many cases.

The Choice of Paint and Tools

When you want to repaint a room with a professional look, you need two coats of paint. This is something you should keep in mind, especially if you are covering a dark color with light-colored paint. The same applies if it is a repainted or primed surface.

In contrast, a ceiling usually takes only one coat of paint. The time for repainting is, therefore, shorter.

The tools also make a difference in how long it takes. They can make a difference in paint drying times. When you want faster results, an automotive spray gun and good water conditions are key factors. The rollers provide an even, smooth and thin layer without streaking. When using a paintbrush, you may spend time fixing streaks and inconsistencies, which will add to the paint drying time.

Drying Time

Many people wonder how long it takes for the paint to dry.

It depends on several factors, such as the room’s size or the type of paint used. This is because the drying time of enamel paint or oil paint lasts between six and eight hours. But latex paint dries much faster.

Temperature is also a factor to take into account. The drying time indoors or outdoors is not the same.

If you are looking for the ideal paint drying temperature, the cure time for oil paint varies between 4 and 32° C. However, it must not be too hot for the exterior paint to dry.  

In general, you should avoid extreme temperatures. It is important that it is neither too hot nor too cold. Humidity also plays a role in the paint’s drying time and speed.

The more humidity in the air, the longer it takes to dry.

When the humidity level is high, the paint takes longer to dry. When you want a faster drying time, the humidity should be lower.

Skill and Experience


If you’ve never painted a room, it might take longer than hiring a professional painter. When you hire a professional painter, it takes much less time than when you paint a room yourself. Because he is familiar with the various stages of these jobs, from preparation to finishing.

Indeed, a professional painter knows that he has eight hours a day to prepare the room and paint the room as well as the ceilings. It will be finished within that time, although it could take you two days or more. Therefore, skills and experience play an important role when trying to estimate the required time to paint a room.
