How To Spray Paint Indoors

If you are willing to paint the home interior, you need to understand the authentic procedure for efficient results.

Remember that you need to have some preparation to perform the job as you want.

Let’s move on to the step-by-step guide on how do you spray paint indoors without making a mess.

Important Supplies For Spray painting indoors

Before starting, I have collected the following tools and materials. Depending on your expertise and needs, the number of supplies might vary.

Step 1: Prepare The Surface

Preparation is the first step to get efficient and appropriate results. Removing old paint, cleaning the dust, dirt, and debris is important; therefore, I always start project from here. This step is very helpful in removing additional mold or mildew buildup. In my case, that location is the the basement area. I opened all the windows and ventilation to make it an open-air area. It will help to dry and prepare the surface well.

Step 2: Additional Surface Cleaning

Sometimes, the indoor surface gets peeled off, highly damaged, and open to fungus. It’s useless to apply the paint directly in such conditions. I recommend you cure all these problems using a scraper, vacuum, or other cleaning tools.

Step 3: Apply The Primer

Next, I started applying the primer using a brush or roller on the indoor surface. It makes the surface smooth and gives more adhesion to the paint when applied. I left the primer for a few hours to dry it thoroughly.

If you are stuck with primer selection, you can buy a suitable primer from well-known brands such as Rustoleum, Zinnser, and more. You should match your budget and other painting requirements.

Step 4: Prepare The Paint

Afterward, I prepared the paint according to the type you have purchased, i.e., oil-based or water-based paints. Always recognize that the paint should not be too thin or thick; otherwise, it will result in a poor finish.

Step 5: Apply The Paint Via Sprayer

Usually, I held the Wagner 590 sprayer in my hands for interior painting projects. My first step was to test the consistency of paint in a paint sprayer before applying it indoors.

I started applying the paint indoors from one corner in thin layers as it will vanish all the imperfections.

Everyone should maintain a standard distance between the walls and tip of the sprayer and let it dry completely after the first coat.

Wait till the specified dry time of the paint and give a second coat to the paint. Don’t paint too fast or slow; balance the speed, and you are good to go.

Step 6: Seal The Spray Paint indoors (Optional)

Sealing the spray paint indoors adds an additional protective layer to the paint. It makes it stick long and protects it from any damage. The primary benefit is to save the paint from peeling off, flaking off, and fading off too quickly. I suggest not using the room or kitchen for about 8 hours after applying the sealant.
