Primer Spray Gun Buying Guide

A primer spray gun needs to be able to stand up to hardcore use with viscous coatings. Responsible for laying down the foundation of every surface — from walls to automobiles. These machines are a fundamental piece of preparation equipment.

These heavy-duty machines must include some essentials — such as:

  • Perfectly-sized primer compatible nozzle.
  • Adequate power.
  • Be effortless to maneuver.
  • Adjustable settings.

Why Use Primer Paint?

Essentially, primer is a ‘flat’ sticky paint that will adhere well to your base medium, as well as fill in any small indentations — meaning, that when you apply that final topcoat, you’ll achieve a flawlessly smooth finish.

Hence, a primer spray gun is called upon to lay down this ‘blank canvas’ in readiness for further coating jobs. Primer should be used on almost every painting project — wood, previously painted dark surfaces, metal, and coated brickwork.

How To Choose the Best Primer Spray Gun

When it comes to selecting the perfect primer spray gun, you may have to read between the lines to fathom out if it includes all you need to provide that all-important base layer.

Follow me as I go step-by-step through each crucial component you should assess before parting with your hard-earned bucks.

Fatigue Icon

Nozzle Size

Make sure that your primer paint gun is fitted with the optimally sized nozzle. As a general guideline, orifice measurement should be in the region of 0.015 to 0.017 inches (1.7 or 1.8 mm) to avoid clogging.

Don’t forget, nozzle size also determines the diameter of your fan pattern — so you’ll need to take the size of your project into account too.

While many sprayers include the perfectly sized fluid tip upon purchase, if you find a device where all other features fit your needs, check to see whether other tip sizes are supported.

accuracy

Pressure Output

As primer is a fairly dense coating, it requires a decent amount of pressure to drive it through the sprayer — and ultimately push out finely atomized paint particles. As a general rule, a minimum pressure output of 20 PSI on compressor-driven HVLP setups is recommended by most pros.

However, as all primers are individual products, they may differ slightly in viscosity. For the most up-to-date advice, check the individual coating manufacturer’s guidelines, or take a look at my Paint Sprayer Pressure Guide.

Portability

I don’t think that there will ever come a time where portability is not an important requirement in a paint sprayer — it’s not like you are going to paint your surface and then leave the machine in situ. Hence, a primer spray gun that’s easy to move will be more manageable.

If you’re considering a handheld unit, this isn’t so much of an issue. Yet for larger machines — a lightweight unit, wheels, and built-in handles are features that maximize portability.

input impedance

Adjustable Settings

Many modern-day sprayers incorporate a whole variety of adjustable settings. And they aren’t bells and whistles just to look pretty.

The ability to dial up the volume or pressure output to complete a job rapidly is advantageous — you don’t want to go at a snail’s pace if you’re an experienced sprayer, and vice versa. Plus, when completing smaller-sized projects, being able to tone down the output is paramount.

input impedance

Ease of Use

Let’s face it, we all want an easy life — why complicate things? Hence, why would you want a sprayer that seems like it requires a college degree to operate? Even the most accomplished professionals will appreciate a machine that’s straightforward to use, set up, and clean.

Look for user-friendly functions for both pre, during, and post-task. A great example of this is the PushPrime feature found on many Graco devices — at one push of a button, priming commences.

Compressor vs Inbuilt Motor

Further down, when you check out my nine of the best, you’ll notice a mix of compressor-driven and inbuilt motor machines. Consider which is best for you. Naturally, this will be dependent on job size and type, and also the frequency of use.

However, a unit with an inbuilt turbine can sometimes keep costs down — as you don’t need to invest in a separate external compressor. That said, if you already own a compressor for other power tools, then perhaps it would be money better spent on a plethora of spray guns.

How To Use a Primer Spray Gun

Using a primer spray gun may seem like a formidable task, but with a little determination, preparation, and my handy how-to guide, you’ll be spraying like a pro in no time at all.

As there are so many different surfaces you can prime, I decided to focus on straightforward kitchen cabinets. However, the technique is pretty much similar for most other base mediums.

What You Will Need to Follow This Tutorial

Before you start, make sure that you have everything to hand to ensure that you achieve the best results.

  • Primer spray gun.
  • Primer.
  • Floorcloths.
  • Screwdriver.
  • Stir stick.
  • Sandpaper.
  • Cleaning cloths.
  • Water.
  • Masking tape.
  • Coveralls or old clothes.
  • Personal protective gear — mask, respirator, goggles, sprayhood.

How To Spray Kitchen Cabinets with Primer: A Step by Step Guide

Step 1: Preparing Your Furniture and Workspace

  1. Start by choosing a spacious, well-ventilated area and lay down your floorcloths.
  2. Place your cabinets in the center and set about removing all the doors and handles that may be present. It’s a great idea here to attach hardware and screws together with masking tape and label them.
  3. Sand all the surfaces of the cabinet frame, doors, and any drawer faces. Remember — go with the grain when sanding, as this will reduce any scratches.
  4. Once you have completed the sanding, wipe the surfaces down with a damp cloth to remove all the dust. Then allow it to dry completely.

Step 2: Start Priming

  1. Put on all of your safety gear and set your sprayer up — following the manufacturer’s guidelines.
  2. Start spraying! Maintain a distance of 12 inches from the cabinet surface for optimum results. Another handy hint for the best results is to spray in the same direction of the wood grain if possible.
  3. Pass each previous spray stroke by at least fifty percent to ensure even coverage.
  4. Typically, most primer manufacturers recommend two coats. So, follow the instructions as to how much time to leave between coats before you progress to the second application.
  5. Once you’ve finished applying the second coat, allow it to dry completely before moving on to your topcoat.

Step 3: Finishing Up

  1. Once you’ve finished with the second coat of primer, try to clean your sprayer as soon as possible. If you let residual paint dry in the unit, it will be harder to clean in the long run and could cause long-term damage.
  2. Once your final finishing coat has dried, reattach all the hardware, doors, and handles.
  3. Tidy away any floor cloths.

Conclusion


To finish off this all-encompassing review, let’s take this opportunity to extend your coffee break and quickly recap.

When choosing your ideal sprayer, keep in mind that primer is pretty viscous — ensure the nozzle size is primer-compatible. Also, ask yourself whether the machine has enough grunt to lay down this highly-demanded base layer.

Furthermore, a lightweight portable unit is central to accomplishing your task — it will allow you to move around your project effortlessly. While adjustable power and paint output settings will provide more control — resulting in a perfect finish.

So, as the saying goes, fail to prepare, then prepare to fail — the best primer spray gun will guarantee that failure is just another word in the dictionary.

Primer Spray Gun FAQs

Q: Can You Use Primer in a Paint Sprayer?

Yes, you can. Using a paint sprayer to lay down primer will deliver far better results than a brush or roller. The whole idea of primer is to seal surfaces, reduce imperfections, and provide better topcoat adhesion — creating a blemish-free finishing layer.

Q: What Tip Do You Use To Spray Primer?

As a general rule, between a 0.015 and 0.017-inch nozzle is best for priming. However, as there are different viscosities of primer available, it’s usually best to check the individual primer manufacturer’s recommendations.

Q: What PSI Should I Use To Spray Primer?

You need a pressure of at least 20 PSI to spray primer when using an HVLP machine.

Q: Do You Have To Thin Primer for an HVLP Sprayer?

It depends on the individual HVLP sprayer. Many models may require some dilution of primer to prevent clogs. However, specifically designed primer spray guns such as the Iwata LPH440-181 Primer Spray Gun can handle most primers without thinning.

Q: What Size Air Compressor Do I Need To Spray Primer?

There are two figures to take into account when selecting the correct sized air compressor — PSI and CFM.

As mentioned in the question above, you need the pressure to be at least 20 PSI. As for the CFM, it depends on the spray gun. Some sprayers will have a rating of less than 10 CFM. However, the industry suggests using a compressor with a rating of at least 12 CFM.

Q: How Many Coats of Chalk Paint Should I Use?

Generally, two coats of chalk paint should be sufficient to provide even coverage. However, if you’re coating something dark, it’s possible you will need to use three — depending on the effect you’re trying to achieve. If a rustic distressed finish is your aim, two should be enough.
