1.5mm, 1.6mm-Multifunctional nib suitable for primer and single-stage paint. However, thinner coatings pose a risk of orange peel because they cannot be properly atomized. These sizes are also ideal for varnishes. 1.7mm, 1.8mm-1.7mm is the minimum size that most primers should use.

What size tip should I use to spray primer?
First, examine the coating that will be sprayed. Heavier coatings will require a larger orifice size than lighter ones. 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.
Can you spray primer with a 1.3 tip?
For spraying clear coats on small parts and projects, we recommend a 1.2mm tip. For spraying a whole car, a 1.3mm tip is recommended. The 1.4mm tip is perfect for base coats and metallic as the droplet size allows the particles to self-orient to eliminate streaking and mottling.
Can you spray epoxy primer with a 1.3 tip?
I’d try the 1.3. If that acts funny, the 1.7 would probably work but you’d need to spray faster. I spray my epoxy with Harbor Freight guns that have a 1.3 tip if I remember correctly and it’s done fine.
What size tip should I use to spray epoxy primer?
1.4-2mm
What is the recommended tip size for spraying TotalBoat 2-Part Epoxy Primer? The recommended spray nozzle size for spraying any of the TotalBoat 2-Part Epoxy Primer products is 1.4-2mm. This applies to all conventional and HVLP guns, including siphon and gravity feed setups.
Can you use a 1.4 tip for primer?
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.
Should you thin primer to spray?
Can the primer be diluted? If it is on the thick side, you should dilute it to ensure effortless application with your paint sprayer. Then pour the primer into the paint container.
What causes orange peel in paint?
Orange peel is typically the result of improper painting technique. It is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular or applying excessive paint.
Can you spray clear coat with a 1.4 tip?
The 1.4mm tip set up is ideal for use with base coats, clear coats, single stage, primers and other light to medium and some heavier viscosity paint coating materials. The 1.4 mm is a very universal tip size.
How soon can you paint over epoxy primer?
1) recommend waiting 24 hrs before top coating, but depending on temp can be sooner. 2) Up to 7 days after epoxy can topcoat without sanding or scruffing. no additional primer required if the surface is good.
Can you spray epoxy primer over body filler?
46 Epoxy primer must dry for one hour and all metal work must be completed before starting the body filler process. Applying body filler over epoxy primer provides maximum corrosion protection for the metal. Apply filler within seven days of applying epoxy primer to maximize adhesion.
What do you thin epoxy primer with?
Adding 5% lacquer thinner to epoxy reduces epoxy’s compressive strength by 35%. As such, it’s no longer suitable as a structural adhesive. Adding a solvent can extend curing time, making your work unpredictable. Adding a solvent can cause the epoxy to shrink and crack over time.
How do you know what size spray tip to use?
To Choose The Right Tip For Your Spray Project, Follow These Recommendations: Choose a tip with an orifice size rated for the paint or coating you’ll be spraying. Light coatings such as lacquers, stains, and enamels require a small tip, while heavier coatings such as texture require larger spray tips.
Can I use spray gun for primer?
A HVLP (High Volume, Low Pressure) spray gun uses a high volume of air going through the gun to atomise the primer instead of high pressure. The low pressure coming out of an HVLP gun applies much more primer on the vehicle instead of in the air. So you save paint and save money…
What size tip should I use to spray polyurethane?
013 – 015 Medium
Spray Tip Chart – Sizing Guide
| Material Type | Tip Size | Material Thickness |
|---|---|---|
| Polyurethane | 013 – 015 | Medium |
| Solid Stain | 013 – 015 | Medium |
| Low VOC varnish | 013 – 015 | Medium |
| Interior Latex | 015 – 017 | Medium |
Can you spray primer with a 1.7 tip?
First, examine the coating that will be sprayed. Put simply, heavier coatings will require a larger orifice size than lighter ones. 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.
What PSI should I spray base coat?
When spraying base coat clear coat systems, you want to spray at 26-29 PSI. You measure this PSI by pulling the trigger and letting air flow through the tip of your gun with your dial or digital readout saying 26-29 PSI.
How do you know if paint is thin enough to spray?
Here’s what you do:
- Pour the paint into the bucket.
- Add ½ cup (118 milliliters) of water for every gallon of paint.
- Mix thoroughly.
- Check the thickness by running the paint through a funnel. If it flows freely through the funnel, you know the paint is thinned enough.
Is it better to spray or roll primer?
All the time you saved in preparation will be lost in how much longer it takes to roll on paint. Regardless of the preparation time, you can paint a wall many times faster with a paint sprayer than with a roller.
How many coats of primer do I need?
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.
How much thinner do I add to primer?
For spray applications on construction or home projects, begin by reducing the primer by 10 percent. This would call for adding approximately 3 oz. of paint thinner to each quart of primer (32 oz. x 0.10 = 3.2 oz.), or roughly 13 oz.
