How to Choose The Best Primer Spray Gun
As stated earlier, choosing the best primer spray gun is not going to be a simple task. If you have never purchased a spray gun in the past, then you need to know how to choose the right model for you. Luckily, I have compiled everything you need to consider when purchasing the best primer spray gun.
Cleaning Options
You will quickly learn that different primer spray guns will have a different cleaning procedure. Note that some are difficult to clean while others are simple to clean. For starters, avoid the models that have to be completely disassembled during cleaning.
Although cleaning an entire sprayer is ideal, you will spend a lot of time assembling and disassembling the machine. You are better off with a model that can be connected to a garden hose for faster cleaning. However, if you have the time, then you can always go for the other models.
Warranty
You have probably noticed that primer guns are quite costly when compared to other spray guns. Well, what would help you get peace of mind while using your expensive gun is an extensive warranty. It can be quite frustrating when your sprayer breaks down on the very first task.
Understand that having a warranty gives you some kind of safety net. Generally, look for a model with at least a one-year warranty when shopping around for the best primer spray gun. It would also help if you purchased a spray gun with several replacement parts.
Adjustments
You need a lot of controls when buying the best spray gun for primer. Note that a lot of primers will come with different thickness. You will, therefore, need to change the speed flow and paint flow constantly depending on the type of primer.
If you are thinking of using your sprayer for multiple projects, then the adjustable features will always come in handy. Having a versatile model ensures you get value for your money. Note that every project will need different speed and paint flow settings.
Weight
When looking around for the right primer spray gun, you have to consider the weight. Note that you will have to hold your gun for long durations at a single time. A heavy gun will require frequent rest breaks which will impact the quality of the finish.
However, note that a lightweight sprayer will not be ideal for a large project. This is because you will need to frequently fill up the paint cup. Understand that a powerful sprayer will always be heavy due to the motor size.
About Primer Spray Paint
Primer spray paint is used to prepare wood, metal, or canvas before painting. Note that the primer functions as a sealant before you can start applying the paint. When used on wood projects, a primer spray will help avoid an uneven finish. There will be even penetration on the bare wood, thus ensuring a high-quality finish.
Note that primer spray paint is also used on metal surfaces to increase corrosion resistance. Understand there are many different types of primers specially designed for different types of surfaces. You must, therefore, choose the right primer for your project.
Some of the benefits of using primers include the following:
Increase spray paint adhesion
Improve corrosion resistance
Ensures you get a smooth and even finish
Smooths out uneven surfaces

What size nozzle is best for primer? ›For example, primers are usually thicker than the accompanying paint so you should use a 1.7 or 1.8 mm tip to prime most surfaces. Most painters will stay in the range of 1.2 to 2.0 mm unless the paint being applied is specialized.
How many coats of primer should you spray? ›You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
Is it better to spray or roll primer? ›The easiest way to ensure an efficient application of primers is to spray them on. The material is atomised and applied to the surface precisely with reduced spray mist thanks to WAGNER technology. You also save time and effort as there's no need to laboriously cover large areas with paint rollers.
Do professional painters use spray guns? ›When it comes to speed and ease of use, using a paint sprayer is the way to go. This is the main reason why so many professional painters use them. But for those looking for quality, nothing beats a roller. It offers a more even finish, a superior texture, and adheres much better.
What spray gun is better gravity or suction? ›Gravity feeds require less air pressure to atomise the paint, providing the direct benefits of lower overspray, less paint wastage, and a greater level of control for the painter. Thanks to these advantages, the gravity feed gun typically delivers better finishes.
What is the best pressure to spray? ›What is the best air pressure for spray painting? Again, it's essential you check your specific model's recommendations, but your HVLP spray gun PSI will likely sit between 25-30 PSI for something like using an air compressor for spraying cars, rising to 40 PSI in some cases where higher atomisation is needed.

How many coats of 2K primer should I use? ›
Apply the 2K primer :
Apply 2- 4 coats allowing a flash time between coats of 5 to 10 mins. Thinning ratio's can change depending on the spray gun set up. Once the primer has dried wet sand with Grit P600 prior to applying the 2K colour coat.
Because primer is thicker than body paint and clear coat, it is recommended you use a 1.8mm tip and air cap when applying primer.
What is the perfect nozzle height? ›Lower Layer Height: It is recommended that the layer height should not exceed 80% of the nozzle diameter. So, if the nozzle diameter is 0.2mm then the maximum layer height should be 1.6mm. Thus a smaller nozzle means a lower layer height.
What PSI should I spray primer at? ›I like to use 26-27 psi for base coat and single stage enamel and 28-29 psi for clear coat. Sometimes, your spray gun will show that you need to set it up to 10 pounds of pressure.
What is the difference between 1.3 and 1.4 tip spray gun? ›For the spraying of the entire car, a 1.3mm nozzle is recommended. The 1.4mm tip is ideal for primers and metal coatings because the droplet size allows the particles to be oriented automatically, thereby eliminating streaks and spots.

Is tapping or spraying better? ›Tapping. Whether you should spray or go for one-taps with Vandal depends on the situation you find yourself in and especially on your positioning. Vandal's spray is pretty chaotic on its own, so in long-range encounters, one-tapping will often be just better.
What are the disadvantages of HVLP spray gun? ›Disadvantages of HVLP paint sprayers
Since there are lower pressures involved, the painting speed will be slower. Because the lower pressure means that high viscosity paints are not handled as well, you may find that you have to heat the fluids using the circulating paint stove.
While air spray guns use high-pressure air to finely atomize fluids, HVLP spray guns spray fluids softly with air pressure reduced to around 0.05 to 0.1 MPa (7–14 psi).
What PSI do you need to paint a car? ›Look for a minimum of 15 PSI, with some applications, such as clear coat, better-suited to 20 or 25 PSI. HP: For auto painting, a 10 HP compressor will typically suffice. However, higher HP compressors may operate more efficiently and can be used for other tasks.
What wind speed should you stop spraying? ›Pest control operators need to be aware of wind conditions at the time of application, as some conditions are not ideal for spraying pesticides. Ideal spraying conditions are at wind speeds of 6–19 km/hr, which equates to a Beaufort number of 2 or 3.

What happens if nozzle is too close? ›
The nozzle is too close/far from the sheet
If the nozzle is too close to the printing bed, there won't be enough room for the plastic to come out of the extruder. By having the nozzle too close to the print surface, you will essentially block its opening, so that no plastic can be extruded.
If your nozzle is too close to the bed, it will plow through the filament, causing a rough, uneven surface. You could have thin patches where the plastic is being pushed into the bed surface. It may be difficult to remove.
