A high-quality paint sprayer can save you a ton of time, get you professional looking results, and be easy to use.
Paint sprayers also are much better at reaching corners or small details with ease and an even layer of paint. Not to mention that with proper care, they save a ton of mess and last longer than brushes and rollers.
Interior Wall Paint Sprayer Guide
Let’s cover the two main types of paint sprayers and how they work.
Airless Paint Sprayers
Airless paint sprayers work by pushing paint from a container through a flexible hose and out a spray gun. This spray gun has a fluid pump that does not use air.
The pressure and spray nozzle size determine how much paint is sprayed at a time.
Airless spray may sound like a complicated technology, but it is actually used very often.
The most common household example of an airless sprayer is a shower head.
Graco, one of the leading paint sprayer manufacturers, describes the technology like this:
In the depiction of spray from a gun, high pressure forces fluid through a small nozzle (spray tip). The fluid emerges as a solid stream (sheet) at a high speed. When the solid stream hits the air, it becomes disrupted. This disruption breaks the fluid into fragments initially, then ultimately very small droplets that form the spray pattern.”
Airless sprayers boast speeds up to 10 times faster than brush painting while producing an even coat of paint.
They can also be used on a variety of projects, including interior and exterior walls, painting furniture, and more.
HVLP Paint Sprayers
High Volume Low Pressure paint sprayers, on the other hand, use air to push paint from an attached container and skip the hose.
Paint Zoom describes the way HVLP spray guns work as follows:
The paint is delivered by means of a cup which is attached directly to the spray gun. There are three different kinds of HVLP spray guns, gravity feed, pressure feed, and siphon feed.
The siphon feed spray gun uses pressurized air to create a siphoning action at the nozzle. The siphon feed spray gun has the paint cup located below the nozzle.
Due to the difference in atmospheric pressure, the paint then moves towards the vacuum area and comes out of the cup. The atomized air pressure determines how much fluid is sprayed by the paint sprayer.
If you want fast application then you are looking for a spray gun with a higher atomized air pressure. However, higher atomized air also means more overspray. The siphon feed spray gun is not efficient because it does not give you enough control of the atomized air pressure and therefore you cannot control the amount of paint being sprayed.”
Which is better for interior walls?
HVLP sprayers work for interior wall projects, but they are really best for smaller scale projects like painting furniture or a small accent wall.
For a lot of space to cover on larger projects, airless sprayers are the way to go.

Paint Sprayer Tips and Tricks
As with any painting project, make sure to prep the area you are painting:
- remove all artwork, furniture, etc from the area you are painting;
- remove light switch and outlet covers to ensure you won’t accidentally paint them;
- cover the floor and any trims you don’t want to be painted.
Even the best paint sprayers may have some over spray mist, so it is best to protect surfaces you aren’t painting thoroughly.
Clean the walls. Moisture or dust can seriously mess up your paint job, so make sure you clean the walls first. Most of the time a simple damp rag will do the job, but there are also cleaning products on the market for serious messes. Let the walls dry completely before applying paint.
Also, fix any previously existing paint drips by sanding them down and repair any unwanted holes in the wall before painting.
Make sure you have all of the necessary safety equipment, such as goggles, gloves, respiration mask, and safety ladders. Have a brush or roller handy to quickly fix any drips or imperfections.
Always practice with your paint sprayer before committing it to your interior walls. Old cardboard boxes are a great place to test out your paint sprayer and make sure you have the hang of it.
Clean your paint sprayer (no more than two hours after use) thoroughly every time you paint with it to maximize its lifespan. Soap and water will work for most types of paint, but oil-based paints will require the use of mineral spirits to clean properly.
Investing in a great paint sprayer is a must for any Do It Yourself fanatic. Consider your budget and storage space when shopping for your paint sprayer. Care for your tool properly to ensure that it will last for a long time.
