How to Paint Interior Walls : Step by Step

The process is quite easy, and with only these three steps, it's manageable to have your walls painted to your desire. If you do not have any experience using a sprayer before, you might consider trying it on a different surface before starting on the wall. Once you have understood how it works, you can begin working on the walls.

If you are planning on painting the walls, you will have to cover the ceiling. Paper can make the perfect cover. Also, include the windows, door, and any other surfaces you don't have to paint.

After you have successfully covered all fixtures, follow the following steps:

Step 1. Preparing the surface

Before painting any surfaces, always clean them thoroughly, preferably using a cotton cloth. Cleaning ensures no dust and stain is left on the wall surface that might affect the painting outcome. To have the best finish, fix any dents and flaws on the wall, the surface should be as smooth as possible.

Step 2. Prepare the paint

Preparing the paint for use on a sprayer is different as compared to that of using color- brush and a roller. Make sure the paint is way thinner than that of using a brush. Always follow the manufacturer's guidelines so that you do it right. (source)

Step.3. Spray painting the interior walls

Always start from the corners when holding the sprayer from a safe distance. Work your way to the rest of the wall making equal strokes. The edges can prove to be challenging, and you can hold the sprayer at an angle to cover all the areas on the corner, paint one wall at a time without moving to the next. For you to effectively paint interior walls, hold the spray paint machine at an angle of 90 degrees.

To get an even and smooth finish on every section, make sure you overlap the strokes before moving to a different part. Before moving into the painted room, give the paint enough time to dry. Allowing it to dry is crucial as wet paint easily gets dirty. In case you need to do a second coat, follow the same steps.

Spray painting the ceiling

If you plan only to paint the ceiling, ensure you have covered the upper side of the wall to avoid runs. Just like on the wall, make smooth overlapping strokes. The ceiling should take you less time compared to the walls.

To avoid getting paint on your clothes or face, hold he sprayer in a way that is not directly on your head. The pressure on the sprayer machine should be even, start with low pressure and slowly increase until it feels right. If your ceiling is around nine feet high, which is the average height, you will not require a ladder.

What Should You Spray First Between Walls and the Ceiling?

When painting using a brush or a roller, it might not affect the outcome no matter what you choose to paint first. However, when using a paint sprayer, you should always start with the ceiling before you paint the interior walls.

Before you proceed to the walls, make sure the ceiling is well dried. Starting with the walls could have you repeat the walls, which can be tiring, especially if it's a different color. (source)
