These are our picks for the best indoor paint sprayers in the industry. You can decide what’s right for you and start painting away. But wait – are you still a little confused as to how you should go about choosing the right paint sprayer for your indoor painting project? Then look at our guide on how to choose the right paint sprayer for interior walls.

Know the types of indoor sprayers – Airless, HVLP, Pneumatic

You may be looking for the right paint sprayer for your interior walls. In case you’re wondering how to go about this, here’s a quick guide to help you purchase the right spraying system for your needs.

Airless Sprayer

An airless paint sprayer works by pumping paint at high pressure through a long hose and out the spray gun’s tip. The pressure can be up to 3000 PSI. These are generally fast sprayers. And they easily atomize coatings without the need for significant amounts of thinner. 

The tip of the machine is designed to break up paint into small droplets. Different tips work with different materials of varying thickness. The size of your sprayer’s tip also determines the fluid delivery of the device. Airless sprayers pump paint directly from the can or bucket, so you can keep spraying without having to transfer paint from one container into another.

Airless sprayers cannot be adjusted in terms of pattern or amount of paint – therefore, you get less control over your fine finishing needs. But you can always use a fine finish airless tip for the best results with an airless sprayer.

HVLP Sprayers

HVLP stands for High Pressure – Low Volume. This is a device with which you can spray with ease and control for smooth, professional-looking finishes. The device uses either standard high pressure compressed air or externally fed HVLP turbine air to break up the paint of the material you want to spray. It can also use compressor-assisted externally fed turbine air, although this is less popular.

HVLP guns feature either siphon guns or gravity guns. In siphons, a suction would be created by the flow of air past the reservoir, and this would suck out the fluid and split it into particles. Gravity guns use gravity to draw the paint downwards and combine it with a high-speed engine jet. HVLP guns work at low pressures, between 10 PSI to 20 PSI. They can spray a large volume of paint with minimal waste.

HVLP guns also have 3 features – air pressure, paint flow, and fan size. These are usually adjustable to varying degrees and give you a lot of control over your device.

Pneumatic Paint Sprayers

These sprayers use compressed air to break the paint down and spray it over a surface. These give a nice smooth finish. Between these 3, they use the most paint and tend to be a little messy. But these are also the most affordable.

What should you look out for in a good interior wall paint sprayer?

Now that you know the different kinds of spray guns, you should know which features to look out for to give you that perfect finish on your interior walls.

1) Power Source

What’s more convenient for you – a cordless interior spraying system? Or a corded one? Check out the power source required for the system you’re looking at. It could be electricity, battery-operated or even gas.

2) Size of the project

Assess how large your project is before choosing a system. An airless sprayer would be apt if you have a large project to get done quickly. But if you have a smaller interior paint job and you want to pay attention to details, like doors, or add splashes of color, then you should opt for an HVLP spraying system.

3) Size of the paint sprayer

Do a quick once over of how much space you can allot to store your system. Accordingly, choose one that is at a convenient size for you.

4) Weight

A durable and lightweight sprayer will be ideal for interior wall painting jobs. You can choose a heavy professional model too, if the scope of your painting job is large.

5) Capacity

Your sprayer will come with a paint cup with a capacity of half-quart, full-quart, or 1/3rd quart normally. There are different sizes of cups one can check out.

6) Adjustable Models

Ensure that the system you’re looking at has adjustable fluid control, air pressure, and fan size settings. If it’s airless, look out for adjustable pressure controls. This will help you use different paints and materials with the same system.

7) Filters

Indoor sprayers with inbuilt filters may cost a little more but will save you a lot of effort, time, and even money in the long run. This will also limit the clogging and reduce the cleaning time.

8) Portability

Paint sprayers usually come with either of these two mobility methods– they can either be moved around in a backpack or on wheels. If your project requires a lot of leg work, ensure you choose an easy system that you can move with ease.

9) Quick Cleanup

You wouldn’t want to waste hours on cleaning up your system, right? Try looking for painting systems that can be taken apart easily. Many also have easy to clean guns – all you would need to do is attach a garden hose and flush it out. Find out how to clean your spraying system before purchasing it.

10) Price & Warranty

Keep a budget for yourself and choose a paint spraying system that best suits your needs. And check out the warranty options on whichever unit you select. Some are a year-long, some go on for 2 years, and some come with certain terms and conditions.

What are some accessories that will help me in my indoor painting projects?

1) Nozzles and tips

There’s a wide variety of spraying tips that can be used for different materials. The width of the tip will decide how thick a material it can spray. All tips come with varying orifice sizes and fan spray widths. You can recognize these with the 3-digit marking found on the tip.

Smaller openings (13 and lower) are suitable for acrylic and top-coat paints, while 17 is for thicker materials such as primers and lacquers. Keep extra tips with you.

2) Hoses

You can use longer hoses or extensions to reach higher areas. There are certain hoses for nooks and crannies. Make sure your hose is firmly attached to the machine. If you’re painting a large area, get a hose that’s at least 25 feet long.

3) Protective Gear

Get masks, gloves, or even a full-body suit if needed.

4) Extension Rods

You’ll be able to access harder to reach spots and paint large areas.

5) Filters

You can get extra filters so that you can use the extra pair if you are cleaning or drying one pair. You’ll save time and reduce the wear and tear of the filters.

How to Paint Indoor Walls?

  • Assess the size of the walls you want to paint.
  • Select the right paint spraying gun
  • Buy good quality indoor paint
  • You may have to thin the paint, depending on what spray gun you’re using.
  • Also, mix your paint to avoid any blobs.
  • Wear protection, such as a face mask.
  • Clear your work area of any objects.
  • Remove all the furniture and cover whatever is left. Mask your windows and lighting.

FAQs

Can I use a paint sprayer for indoor walls?

Yes, you can. These are good to create a professional finish in very little time. They are said to be around 10 times faster than a roller.

Why should I choose a paint gun over a brush or a roller?

Brushes and rollers require a lot of effort and energy to use. And a lot of time, as well. A paint sprayer is easy to use, saves you time, and can help you get into those tricky nooks and crannies from a distance. You won’t have to bend or move your body as much, so you’ll have a higher amount of accessibility. 

Further Reading: Paint Sprayers vs Brushes

What are the disadvantages of using a spray gun over a roller?

Paint sprayers create more overspray than rollers do. They are generally more expensive.

How do I determine how much paint I will need for spray painting my interior walls?

That depends on the dimensions of your wall and what kind of coverage you’re looking at. Calculate the length and breadth of your walls, or the length and height, and you’ll be able to get an estimate.

Do I need to clean my sprayer after every use? How do I do this?

Paint hardens and can also contain many impurities. You should ideally keep your sprayer as clean as possible before you intend to keep it back in the shed or wherever you store it. Some would need you to disassemble the body and clean it with water. You can attach a hose to the gun in other spray guns and flush out any remaining paint.

Which paint sprayer for walls don’t need diluted paint?

You’re looking for a system that has a turbine powerful enough to break up thick paints without thinning them. You’ll also need to look for a system with the right tip or nozzle size. There are certain powerful airless sprayers you can use without diluting latex and other heavy materials.
