Shooting ICA Polyurathane8/17
I have a large China Cabinet to finish made from stained Crotched Mahogany.
I will be using an ICA sealer and poly..
my rep told me to shoot the sample with a cup gun. which took me back a bit, as I have almost always shot Ilva and sayerlack with a Kremlin air asst.
anyone have advice in shooting a high built, cut and polished finish using ICA?
I can use a pot, cup or Air asst..
input would be appreciatED
only benefit to using the cup gun would be easier to clean if it sets up on you. the air assist would give you the best result for laying it out and atomizing the product.
Seems like it would be pretty expensive to mix enough product to spray a sample using the Kremlin unless you have a gravity feed attachment. The cup gun will be fine as long as you pay attention to the wet film thickness as you spray. You can then duplicate the job using whatever equipment you want to use.
I always used polyester to build a high gloss polished job then applied the 2K urethane as a topcoat for ease of buffing. If you have UV capability you can do the entire process in a day.
What ica product code are you using? is it 2 component or mono component? I have used it with a kremlin but you will risk microbubbles if you lay it on too thick and orange peel if too thin. You have to watch your humidity that it is not too dry and you do not want to dump a lot of air flow on it until it dulls out. too much air all at once will not let the product flow out on the surface while drying and you will get onion skinning.
7 days minimum dry time before polish minimum.
its a dual component 436-1395, Lucido polyurethane. And a 876-9068 Ora Verde Pu hardener.
My coworker sprayed it with a CAT grav gun and it had micro bubbles all over it.
so my question to Dave is, In sprayin a 9" x 6' china cab....what would be the best rig to use?
I must apologize,
I shoot the verde from chemcraft quite often, I shoot it out of a conventional pressurepot, I get issues from time to time in my airless with microbubbles. I reduce the sealer 15% with their medium polyurethane reducer, And reduce the topcoat 10% with the medium polyurethane reducer. Lays out beautifully.
I was thinking of using a binks 2.8. pot with a DeVillbiss transtech.
I have a 1.4 to a 2.2 tip set up. and have aircaps to make it hvlp, lvmp and conventional..
do I want high pressure for good atomization or do I want to dial the air down to 10-20 psi?
I use a binks 2.5 gal pressure pot, with a 1.8mm tip gun. The pot pressure is 12-15 psi. The specific gun i use works best at ~20 psi. It is a Devillebliss FinishLine HVLP, but every gun is different, you'll have to play around with the settings on your gun for best atomization.
I once had a kremlin pot gun that wouldnt atomize unless i had ~60 psi going to the gun.
Thanks for the advice Tyler. Ill mess around with my rig and work something out.
I appreciate everyone's input
hope you are not just wearing your half mask to spray this.
