What Size Tip To Use To Spray Orange Pell Youtub

Spray-Gun Technique to Forbid Orange-Pare

The correct force per unit area settings should do the trick. March 18, 2005

Question
I'm at my wits stop. I go orange skin with every setting, and every blazon of finsh practical. I've gone from a 94 air nozzle to a 91, high pressure to low pressure and thinning my lacquer, polyurethane, varnish, to not thinning. Is there anyone who is getting great results using the Binks

From contributor R:
I have used Binks Mach 1 for years without trouble. Have you tried a retarder instead of thinning? Orange peel is usually from drying to fast.

From contributor 1000:
Binks Mach i SL is a nifty gun. What product are you spraying and what are you lot thinning with? What viscosity are y'all spraying at? What are your pot force per unit area settings? Try your viscosity about 25 sec Ford #iv (20 sec Zahn #2) with nigh 10 lb fluid and 40 lb air with the gun feed flow about 1 total turn open and experiment from in that location. That should get you in the.

From contributor A:
My Binks Mach 1 became a super gun when I installed the special kit that regulates the air pressure that pressurizes the quart cup. Assuming yous're using a quart loving cup, the kit allows you to punch in the pressure on the within of the cup independently of the atomization pressure. Cup pressure should exist a fraction of atomization pressure, but is usually the aforementioned. This can atomic number 82 to overspray and orangish peel.

Don't count on your Binks distributor to know nearly this. Mine didn't, so I went to the Binks website and plant the parts. When I gave him the part numbers, he ordered the kit and it was easy to install. It makes the gun a fiddling heavier, only not so much as to make you lot want to remove information technology.

From the original questioner:
I'll check out the Binks site for the kit and give that a try. I don't recall that the judge that is below the handle gives y'all the info that you really demand though.

From contributor B:
If you�re getting orange peel subsequently all y'all've done and so I would bank check your gun to see if the air vent is blocked.

From Paul Snyder, forum technical advisor:
Start by making sure the viscosity of the end is right for the needle/nozzle/air-cap you lot have on the gun. If the finish is besides thick, information technology won't atomize well. Use a viscosity loving cup to measure out the finish and thin as needed. Here's a description of using a viscosity cup - Measuring Viscosity.

So brand sure the gun is atomizing the terminate well. The terminate should break up into tiny aerosol when you have the settings right. If the stop isn't atomized well, the spray design will look more like the picture beneath on the left. Good atomization looks like the picture show on the right.

If y'all're still getting orange pare once y'all take the gun atomizing well, make sure y'all're keeping the spray gun the proper distance from the surface and moving at the right speed to maintain an even wet coat that'south not too thin or thick (wet mils). If yous're still getting orangish peel, then adding retarder should take care of it. In that location are some tips to eliminate orangish peel at this link - Eliminating Orange Peel.

When everything is working right, the sprayed surface should look almost similar drinking glass when it'south moisture.

From the original questioner:
I'chiliad thinking that my problem is that I just don't understand how to ready up the air pressure. What practice you recommend the pressure at the air compressor should be? I have ane of those small knob controlled regulators at the base of my gun. What exercise yous recommend I ready that to? I realize that the settings are unlike for different liquids, just I demand a starting indicate.

From Paul Snyder, forum technical advisor:
After thinning your finish to the proper viscosity, try this to get started;

* Open up the cheater valve at the bottom of the gun handle all the fashion and leave it there.

* Set the air pressure to the gun at 35-40 PSI.

* Spray a few exam shots and suit the fan width to about 7" wide at 7" - viii" from the nozzle.

* Spray some test spray passes on cardboard, craft newspaper, or scrap boards and conform the fluid menses until it atomizes well. If you're getting large aerosol, plow the fluid downwards.

* Now turn the atomization air downwardly to the lowest setting that yet gives you adept atomization with minimal overspray.

If you use a wider fan pattern, you'll need more fluid and more air force per unit area.
