What PSI should I use to spray primer?
A general rule of thumb is: Heavy-bodied primers and primer surfacers work best when you use a nozzle size of 1.7 to 2.2. Basecoats should be sprayed with a 1.4 to 1.6 nozzle. Clearcoats should be sprayed with a 1.3 to 1.7 nozzle.
Can you spray high build primer over epoxy?
Epoxy doesn’t really fill and neither does etch, that’s what’s the surfacer is for. Epoxy doesn’t need to be sanded, and you can apply your surfacer or filler directly over the epoxy as long as its within the recoat window. High build and regular Primer: You ‘ll be using build Primer when doing body work.
Does epoxy primer need reducer?
To prepare the epoxy primer, shake or stir the primer, and thoroughly mix one part primer with one part catalyst. To reduce any film buildup, this one to one ratio can also be cut with a urethane-grade reducer or comparable solvent solution. This can also improve the overall flow of the primer mix.
How much psi should a spray gun have?
How is the pressure feed gun balanced for spraying? 1 Using control knob on fluid regulator, set fluid pressure at 5 to 10 psi. 2 Using control knob on air regulator, set air atomization pressure at 30-35 psi. 3 Spray a test pattern (fast pass) on a piece of paper, cardboard, or wood.
How much PSI is in a spray paint can?
The maximum pressure for an aerosol can is typically 10 bar (145 psi ) at 20 C (68 F). Therefore, a fully compressed air duster will exhaust air about 10 times the can volume.
Will high build primer fill pinholes?
Any high -quality automotive primer will cover and hide the scratches. Pinholes are not so easy to fix. Pinholes are the tiny voids, bubbles, and pits caused by air that got mixed into the dry micro. Unfortunately, primer is very thick and does a horrible job of filling pinholes.
Can I use epoxy primer as a sealer?
Use it For a Final Sealer – A cool trick we’ve been doing for the past few years is using our epoxy primer as a final sealer before our base coat. Simply reduce it 50 percent and lay a coat or two down to seal up all of your work and have a nice surface to lay your base coat over top of.
Can I paint directly over epoxy primer?
They recommend a sealer over the epoxy before the paint. They said that you can paint over the epoxy, but best results would be with a sealer.. with no issues. I do scuff it when it sits longer, like overnight.
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.
Is epoxy primer safe to spray?
When an epoxy primer is sprayed and is airborne it should be treated with the same respect as a 2 pack paint. Required Protection: If you’re spraying (or near someone spraying ) epoxy primer then you need full respiratory protection. Check with the manufacturer of the primer to see what you need).
Can I spray epoxy primer at home?
Epoxy primer isn’t as dangerous as hardened top coats but you still need good protection when you’re spraying so keep the mask handy and use fresh cartridge filters when you spray. I spray in an attached garage. The door between the house and garage is metal so I seal all edges of the door with duct tape.
What do you thin epoxy primer with?
Method #2: Thinning Epoxy Resin Using a Solvent Solvents like denatured alcohol, lacquer thinners and acetone. All of these solvents are easily available and also do a great job in lowering the viscosity. Also, these solvents evaporate quickly and are unlikely to become trapped in your cured epoxy resin.
What can I use to decrease epoxy primer?
Clean good with lacquer thinner. I don’t think acetone or mineral spirits are strong enough for epoxy. I always reduced epoxy with lacquer thinner.
Where do you apply epoxy primer?
It can be applied on steel, galvanized steel, aluminum, fiberglass, wood, asphalt, and concrete. Prevents rust and corrosion. The main job of epoxy primer is to protect materials against rust and corrosion. A two-part epoxy primer contains zinc phosphate, something that enhances its corrosion-inhibiting properties.
