I bought the Earlex Spray Station Pro HVLP and used it for the first time this weekend. I need some suggestions

Problem:
Spray was splotchy, seemed like it was not atomizing enough.

I adjusted the flow (back knob) it got a little better
finish ran through the cup in about 40 sec
Used Polyurethane and stain (all in one) it stinks but that is what I am stuck with

Any help/suggestions are appreciated, other than sand it down, stain and then finish by hand :)

PS: I posted with over the weekend and seemed to go through, but never showed up. Crash or do the moderators no longer like my posts <grin>

That poly/stain combo leaves a lot to be desired, IMO. Before you spend a lot of time trying to figure out what is wrong with your spraying technique, I would try experimenting with a different type of finish.

what needle size are you using? Straight from the can or have you tried thinning it at all?

Not sure what needle, I’ll have to check, but I did try thinning it a bit. Should I try to thin it more? How thin can I go?

Charlie – I agree the poly/stain combo is crap. I would never use it but that is a lone story.

Snowdog, I have to agree with Charlie’s comment. I have tried to put on the poly/stain combo before and did not like the way it looked. I ended up tossing out a couple of quarts that I had opened rather than continue to use it. And a short time later my wife (who can’t resist passing up a sale item irrespective of whether she needs it or not) happened to be in Lowe’s and bought another couple of quarts on the clearance stand. Since they were on clearance the items could not be returned. I thanked her, of course, but ended up getting rid of them as well.

I have the same spray gun and have found it to be pretty good at applying finishes but I have limited my spraying to oil stains, polyurethane (50%) and shellac. Your finish should spray but I would not try to spray it directly from the can. You should be able to thin it up to 50% and it should spray better.

I sprayed like a pro my first time out with just poly… no problems… I do have problems with stain/poly mix just brushing it on…so don’t use it…then again I don’t stain much … I prefer timber that has its own color..
and remember to strain it…

Yes to do spray application well need enough exercise.
But i am sure that you can do that.

To spray with HVLP gun actually is about the same with air spray gun. If you already familiar with the air spray gun then you can do the HVLP as well as the air spray. Check the viscosity of your material, make sure it is in the range where your spray gun works.

How to use the spray gun

Good luck
