Key Features of the Best Primer Spray Gun – Buying Guide

Best Primer Spray Gun

The requirements of professionals, DIYers, enthusiasts, and occasional DIYers aren’t the same. Therefore, to make sure you target the right product so that you get the best value out of your money, check for the features and form factors that are given below.

Adjustability:

As different painting and priming projects require different outcomes, having a good primer gun with adjustable settings will come handy for your projects.

Look for a sprayer that features adjustable spray patterns so that you can select a preferable pattern to get the work done more efficiently.

In addition to that, the ability to increase and decrease the material flowing rate is another great feature for both professional and DIY projects. This allows you to adjust the spraying speed for different surfaces. You can increase the speed when working on larger objects, and reduce the speed for more work surfaces that require detailed finish.

If you are on a budget, and want to go for a sprayer that requires an air compressor to run the tool, make sure the air flow is also controllable from the gun itself. This will provide you great convenience while working with different materials.

All-purpose vs. Specific Purpose Sprayer:

You will find primer sprayers of different types. All-purpose sprayers are great for DIYers who want versatility, and the ability to use the same sprayer to paint, stain, and prime various types of objects. Considering the price, having such a sprayer will add great value to your money. However, these sprayers handle one or two tasks well, and the rest of the tasks don’t even come close to low-paid professional projects.

As far as applying primer is concerned, using an all-purpose sprayer, make sure the sprayer handles primer materials well. It should be able to flawlessly spray materials of different thickness. If the sprayer requires you to thin thicker materials, make sure it sprayers well after thinning.

On the flip side, there are spray guns only specialized at applying primer on different objects. Professionals mostly prefer using these tools. You can achieve professional level finish using such a sprayer. Also, projects that require more precision such as automotive projects, can be handled with great results with a sprayer that is designed primarily for primer coatings.

Ease of Cleaning:

As primer, paint, and stain materials are messy, you need to clean the sprayer from time to time to keep its performance optimum. The best is to clean the spray gun after each use. However, not all units offer this, meaning some models are difficult to open, while some are much easier to open and clean.

And, there are people who don’t have much time to take care of the cleaning each time after using the sprayer. Cleaning less often isn’t bad as per your sprayer manufacturer instructions. Some spray guns require less maintenance, and there is nothing wrong if you clean the fluid canister less frequently.

Then, again, having an easy to clean sprayer is always recommended. If you prefer cleaning it after each use, be sure to get one that allows you to connect the sprayer to a water hose. This is the most easiest and convenient way to clean.

Variety of Nozzles or Nozzles:

Those who are looking for a versatile primer spray gun to handle different projects, make sure the package includes some extra nozzles or nozzles of different sizes. Some spray guns come with 3 nozzles that can be used for applying light, medium, and thick material in detailed projects or in a wider spray pattern for larger work surfaces.

Overall Durability and Longevity:

Hope that you have no intention to purchase another spray gun for applying primer within a few months. So, make sure you invest in a tool that got solid construction as well as has rust and corrosion-resistant protective properties. Rusting is the main issue that you might face using the tool, which can significantly reduce the lifespan of the sprayer.

Apart from the construction, you can use manufacturer approved protectants to combat rust and corrosion, and increase the lifespan of the metal components of the sprayer.

Portability and Weight:

As primer spray guns are handheld tools that people work with, it’s important that the tool must be lightweight so that it’s possible to work with it for a long period. If you end up buying a feature-dense but heavyweight sprayer, after using it for a certain period of time, your hand will strain and fatigue. So, the sprayer gun should be lightweight, thus, it’s easier to hold and comfortable to work with for extended periods on large projects.

Frequently Asked Questions

Conclusion

In search for the best primer spray gun, I kept it quite straightforward, and listed spray guns that are exceptionally well when it comes to apply primer coatings. Some models might not be able to handle painting or staining that well, but you will be disappointed by how impressively these tools spray primer materials be it thin or thick.

Again, look for versatility if you are tight on budget. For professional projects, it would be better to stick to sprayers that are primarily designed for applying primer. Anything that comes along with, would be extras.

Good luck for your purchase and priming projects.
