The Key Differences Between Exterior and Interior Painting

Painting your home is a great way to give it a fresh and updated look, both inside and out. But did you know that the process of exterior painting has a few key differences from interior painting? If you're thinking of tackling a painting project for your home, it's important to understand these differences in order to ensure the best possible outcome. Here is a look into what makes exterior painting different from interior painting.

Preparation

One of the key differences between exterior and interior painting lies in the preparation process. When painting the exterior of your home, the surface must be properly cleaned, scraped, sanded, and smoothed before any paint is applied. This is because the exterior of your home is much more exposed to the elements, which can cause damage to the surface over time. On the other hand, when painting the interior of your home, the preparation process is much simpler, as the walls and ceilings are generally in better condition.

Type of Paint

Another difference between exterior and interior painting is the type of paint that is used. Exterior paint is specially formulated to endure severe weather conditions, such as rain, heat, and cold. It's also designed to resist mildew and fading. In contrast, interior paint is not designed to withstand these conditions, as it is only exposed to normal indoor conditions. Additionally, interior paint is available in various finishes, such as matte, satin, and gloss, while exterior paint tends to come in a limited range of finishes.

Application

The way in which paint is applied also differs between interior and exterior painting jobs. When painting the exterior of your home, it's often necessary to use a brush and roller in combination with a sprayer, especially when dealing with textured surfaces. This allows for a more even application of the paint. When painting the interior of your home, a brush or roller is usually sufficient, although a sprayer can be used to speed up the process.

Timeframe

Finally, the timeframe for exterior and interior painting projects is often different. Exterior painting jobs can take much longer to complete, as the process of preparation, application, and drying takes more time due to weather conditions and the size of the surface area to be painted. Interior painting jobs tend to be much faster, as the interior of your home is protected from the elements and can be painted regardless of the weather outside.

While both exterior and interior painting projects can be wonderful ways to update and refresh your home, it's important to understand the differences between the two before beginning a project. From preparation and type of paint to application and timeframe, the process for exterior painting is distinct from that of interior painting. Keeping these differences in mind will help ensure that your painting project is a success.
