Painting the interior of a house is an essential home improvement project that can change the appearance of your entire home. However, the question that most homeowners ask is, “How long does it take to paint a house interior?” The answer to this question depends on various factors, such as the size of the house, the condition of the walls, and the painting technique used. In this blog post, we will cover those factors that affect the duration of painting a house interior project.

Size of the house

The size of the house is the most critical factor when estimating the time it takes to paint a house interior. The larger the house, the more time it takes to complete the project. For instance, a small apartment with just one bedroom can take up to two days to paint, while a larger home with multiple rooms can take up to a week or more. Therefore, the size of your house should be the first consideration when estimating the duration of your house painting project.

Condition of the walls

The condition of the walls is also a crucial factor in determining the time it takes to paint a house interior. If your walls are in terrible condition, you will need to factor in additional preparation, which includes cleaning, sanding or patching up dents, and cracks. Proper preparation will ensure that the paint adheres to the walls correctly.

If your walls have a smooth surface, they will require fewer coats of paint. In contrast, if the walls have rough or textured surfaces, they might need more coats of paint to cover them entirely. As a result, this will add more time to your painting schedule.

Painting Technique

The painting technique you use can significantly impact the duration of painting a house interior project. For instance, if you decide to use a roller, it would take less amount of time and effort compared to using brushes. A roller helps to cover a larger area at a time, which speeds up the painting process.

On the other hand, using a brush requires more intricate labor to cover any intricate details such as edges, corners, etc. Professionals would recommend using a brush for places where a roller wouldn’t fit, providing more quality and precision. Additionally, you will need to take breaks when painting with brushes to avoid cramping.

Number of Coats of Paint Needed

Generally, one coat of paint is usually suitable for most walls. However, in cases where you are changing the color of the walls or applying a new layer of paint, you might need multiple coats of paint. The number of coats you require will depend on your preferences, but keep in mind that the more coats you add, the more time you will need to complete the project.


In conclusion, there’s no definitive answer to the question of how long does it take to paint a house interior. Various factors can affect the duration of the project. For homeowners, several aspects are considered to be time-consuming such as the size of the house, the surface state of the walls, the painting method used, and the number of coats of paint required.
