Why does my clear coat orange peel?
Orange peel is typically the result of improper painting technique, and 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..
What size tip is best for spraying clear coat?
1.2mmFor 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.
How much psi do I need to spray clear coat?
26-29 PSIWhen 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.
What CFM does a spray gun need?
0.3 to 12 CFMA spray gun normally operates from 0.3 to 12 CFM. It also means that you need a compressor which provides from 4 CFM to 19 CFM (both for touch – ups and undercoating). Notably, an air compressor with low CFM rating isn’t recommended as it could cause uneven paint flow, or paint splattering.
What is a pressure feed spray gun?
More specifically pressure fed spray guns that utilize a pressure tank with dual regulators. A dual regulated pressure tank gives you precise control over pressure of fluid both to the material and to the air that breaks the material up (the atomization air).
What size compressor Do I need to spray paint?
12 CFMWhile some air spray guns have a rating of lower than 10 CFM, we’d recommend your compressor CFM for spray painting is at least 12 CFM.
Are LVLP spray guns any good?
Our top pick for the best LVLP spray guns is the Campbell Hausfeld Paint Spray Gun Kit, Gravity Feed. It is durable, lightweight, and has a variety of applications. If you want a budget-friendly option that is still efficient and long-lasting, then consider the SPRAYIT SP-352 Gravity Feed Spray Gun.
What size tip 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.
Why does my HVLP spray gun spitting?
Spray guns spit when air is being introduced into the fluid outside of at the air cap. … Fluid Nozzle – The first area to check if your spray gun is spitting is the fluid nozzle. A loose fluid nozzle does not properly seat in the tip of the spray gun and causes air to enter the fluid supply resulting in spitting.
How much psi do you need to spray a car?
10-15 psi when trigger is pulled for base coat is what most say to set your gun at. Personally I spray at about 17 psi when spraying base coat and 20-25 for clear coat using the low volume low low pressure spray guns. The normal scfm that these guns use is 5-7 scfm cubic foot per minute. Volume of air used at 40 PSI.
What does 10 psi at the air cap mean?
It should also be pointed out that the 10 psi at the air cap is pretty much generic to all hvlp guns. That 10 psi is a MAXIMUM air pressure recommended at the air cap.
How many coats of clear is too much?
We send a test card with every order, so use this not only for your color match test but to get a feel for how the clear coat sprays. Practicing on another surface before you start on the vehicle will help you avoid applying too light or too heavy of a coat. Plan for 2-3 coats.
How big of an air compressor do I need for a HVLP spray gun?
Most hvlp guns require around 10-12 or more cfm’s. You can purchase spray guns that only require 3-6cfm’s but you can purchase a compressor for what they cost.
How long do you let base coat dry before clear coat?
You want to give about 15-20 minutes in between base coats and then about 20-30 minutes after your last base coat before you apply the clear coat. If you wait 48 hours, the base coat will be too dry and the clear coat will have a harder time sticking to it.
Should I wet sand before clear coat?
Wet-sand the base coat before starting the clear coat. Wet sanding makes the surfaces smoother. … Once the base coat is smooth and clean, start spraying on about three to four layers of clear coat. Do not scuff the base coat beforehand.
What PSI should I spray paint at?
The working range is between 15 and 50 psi, with smaller patterns requiring lower pressure. No two sprayers are likely to agree on the same settings, so it’s a matter of personal feel. Some typical settings: 15 to 20 psi:Airbrushing, touch-up, shading, sunbursting, and thin finish materials.
How much pressure does a HVLP gun need?
HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure (10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.
How long can you wait to spray clear coat?
30 minutesClearcoat Spray Paint Allow 30 minutes after base coat color has been applied to apply the clear coat. Apply 4-5 wet (but not dripping) coats waiting 10+ minutes in between coats. Each coat should be dry to the touch (not tacky) before moving on to the next.
Do you need a regulator on spray gun?
It’s a good idea to have a regulator on or close to the gun, to mitigate any pressure drops in your system across air lines, and to be able to tune your gun’s spray pattern based on the type and viscosity of material you’re shooting. … Regulators are relatively expensive, and they mount to the hose junction of the gun.
