What size tip is best for spraying clear coat?
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.
Do you need to thin paint for a sprayer?
Yes, the latex paint does need to be thinned. Even though latex paint is water-based, it is thicker than the oil-based paint varieties. The thick latex paint needs to be thinned to be able to spray a fine mist of paint. Before applying your paint, it is a good idea to test out the paint’s viscosity.
Is it worth getting a paint sprayer?
The use of airless paint sprayers is particularly worthwhile in large areas because the advantage of the higher working speed. For a long time, the rule of thumb used to be: use a paint sprayer starting from a 3-room apartment and to paint everything smaller than that roller and brush.
What kind of paint do you use for a spray gun?
Latex paints are the most common type of paint for spray guns today.
What is the difference between HVLP and LVLP spray gun?
LVLP is an acronym for Low Volume Low pressure which means that it uses less air volume (5-18 CFM) then HVLP (10-25 CFM) and lower air pressure (10-30 PSI) than a typical conventional Airspray gun (35-60 PSI). LVLP guns have large air passage like the HVLP guns but the air caps have slightly smaller holes.
Are LVLP spray guns any good?
LVLP spray guns are better than HVLP spray guns because they produce few defects. This is because air bubbles can be produced in high volume which can cause a lot of defects. The LVLP uses low pressure and a thin nozzle which allows a low volume of paint to be pushed out of the gun.
What happens if you put too much hardener in paint?
Thru some experimenting, I found that too much hardener makes the paint more brittle so again, I stick with what the manufacturer recommends.
What happens when you put too much hardener in automotive paint?
Incorrect mixing ratio: If too much activator/hardener is used, or if the correct ratio is not properly mixed, defects may appear in the finished dried paint film. Environmental conditions: Excessive heat or humidity during application and curing can cause surface imperfections such as cracking.
Can I spray clear with a 1.4 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.
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.
What pressure should I set my spray gun?
Setting the air pressure to about 28-29 PSI for clear will ensure you having great flow out. Most HVLP spray guns will use 10-14 scfm at 40 psi. This is volume of air pressure per cubic foot.
