Spraying (Epifanes) Varnish

[Frenchie3958]

Geoff,

My son has worked for DUFOUR when he was student and at school he learned the good way of applying varnish. The room must be at 25°C/77°F but the varnish needs also to be warm, he explained that he got the same results (orange peel) with a cold place (less than 20°c) or with a cold varnish stored in a cold place. He has to redo the job twice. Check these two parameters and good luck....

Frenchie,

Thanks for the info! I'll keep that in mind.

I'm happy to report that after making a series of changes, that I'm getting excellent results. Based upon feedback from this forum and others, I did the following:

1) Thinned the Epifanes 25% with spraying thinner. The viscosity was measured at 25 seconds in a Zahn #2 cup.
2) Increased the diameter of the nozzle from 1mm to 2 mm
3) Replaced the aircap on the gun with the larger one to match the nozzle.
4) Increased the room temp to 70F

Note that I'm using a 4 stage Apollo 1025 HVLP turbine and a 5000 series gun.

The final result looked just like the factory. I'm a happy man!

Thanks for all of the suggestions.
