What Does Primer Do for Interior Walls?

What is primer?

Primer is a product that is applied to interior walls in order to prepare them for painting. It can be used on new construction, or when repainting existing walls. Primer provides a smooth surface for paint to adhere to, and also helps to cover up any imperfections in the wall and to protect against peeling or flaking paint.

Why use a primer?

Primer is an important step in the painting process because it helps ensure that your paint job will turn out looking its best. By using primer, you can help improve the overall appearance of your walls and make sure that your paint color looks true-to-life. In addition, primer can help to extend the life of your paint job by providing a barrier between the paint and the wall.

How do I apply primer?

Applying primer is relatively simple and can be done with a brush, roller, or sprayer. If you are using a brush, start by painting the edges of the wall and then work your way in towards the center. For walls that are very large or have a lot of nooks and crannies, a roller may be the best option. Start by rolling the primer onto the wall in small sections and then use a brush to even out the coverage. Finally, if you are using a sprayer, be sure to hold it about 12 inches away from the surface of the wall as you prime. Thoroughly cover the entire wall surface, making sure to overlap each stroke by about 50%. Once the primer is dry, you are ready to paint!

What kind of primer should I use?

There are many different types of primer available on the market, so it is important to choose one that is best suited for your needs. For example, if you are painting over a dark colored wall, you will want to use a white or light-colored primer in order to achieve true color coverage.

In general, there are two main types of primer: oil-based and water-based. Oil-based primers provide excellent adhesion and durability, but can be tricky to work with and have a strong odor. Water-based primers are easier to work with and have less of an odor, but may not provide as much adhesion or durability.

No matter what type of primer you choose, be sure to read the label carefully in order to understand the proper application method and how long it will take to dry.

What else do I need to know?

In addition to primer, you will also need paint, a paintbrush, and a ladder if you are working on a ceiling. It is also a good idea to cover any furniture or flooring in the area where you will be painting. Finally, be sure to open all of the windows in the room in order to ventilate the area and to help the primer and paint dry more quickly.

Now that you understand what primer is and why it is important, you can start the painting process with confidence!
