Topic tags/keywords: earlex shellac

I have been spoiled for a while using a friends 4 stage HVLP for shellac (sanding sealer) and pre-cat Lacquer. Problem is that he is 15 minutes each way, plus 30 minutes of gabbing. I’m looking to get the Earlex 6003 primarily for Zinnser sanding sealer (dewaxed shellac), seal-cell and armor seal. In looking at the different ones in that price range it came down to the Fuji Semi-Pro. I see in the Earlex 6003 they specifically mention shellac and lacquer, but the Fuji seems to be more about latex.
The Earlex HV5500 seems like it might meet my needs but the info on stages and woodworking finishes seems less, any opinions? (It is $200 less) Not sure how many stages.
For a small shop without a dedicated spray room and breadbox size projects, is the gravity or suction gun more useful? (I have a popup spray tent)
My friend has two feed cups, one with sanding sealer and one with lacquer at all times. He doesn’t clean them after each use and they work fine. Is that common or is that peculiar to his system?
Anyone have experience with the 6003 system?
What is the novice explanation of number of stages and their value?
Steve.

I’ll try and tell you what I know:

First , seal-cell is not meant to be sprayed. All the other coatings you mention are fairly thin with low viscosity. Pretty much any hvlp system will spray them without much trouble.

6003 is a 3 stage turbine and will produce more pressure than the 5500 or a semipro 2. Do you need that, not really. Not for shellac anyway. Air is air for the most part , so what you’re really buying is the gun. The 5500 gun only works with its dedicated turbine. The other earlex guns will work with any turbine, same with the Fuji guns.

As far as top feed , bottom feed, side feed ? Personal preference. I think top feed is easier to clean and I prefer the balance. But, you need a gun and/or filter holder to load the cup cause it doesn’t support itself like a bottom feed. YMMV.

Lots of positive reviews on that earlex 5500 for what you’re talking about doing. No room to grow though if decide to get into color coatings or waterborne heavy solids finishes. Only available with a bottom feed gun.

Put Latex and HVLP out of your mind right now. They really aren’t compatible. Life will be simpler if don’t go there. Bear in mind Latex IS NOT a synonym for waterbased finishes.

The more stages a turbine has , the more pressure it’ll develop. Which will allow you to atomize thicker material.
That’s only part of the equation. The gun , and the size of its needle and nozzle play an equal part.

1. I have to contradict the previous post. I do not know if seal coat shellac is meant to be sprayed or not but it sprays beautifully. Much better and faster than any other method.I think OP already knows that.
2. Earlex 6003 is incomparably better than earlex 5500. It is not only about viscosity, the more stages you have the better atomization you can achieve and better finish. You inevitably run into a situation when you need more pressure to spray a thicker medium and then what ?
3. Some people like suction cups better, some gravity feed guns. They both have pros and cons.
Gravity is more compact and can get into tighter spaces and have less problems with leaking. But you can rotate suction cup up and down more. Gravity feed guns also use all the paint to the last drop. With suction cup you inevitably loose some paint. It might not matter for you but once someone asked me to spray auto paint and that stuff is super expensive. You can easily loose $20 in the suction cup.

The OP referred to Zinnser sanding sealer (AKA Seal Coat) and seal-cell. xedos referred to seal-cell. He said nothing about spraying Seal Coat.

Me, I’ll take a pressure pot any day. You can work at any angle, and no cups to get in the way.

Actually I have an decade+ old Earlex for latex, have painted daughters garage, couple fences and other things. Worked good, but not a small item tool. Only water base paints I believe. That one has constant air flow with the trigger only for the paint.

I was referring to GF Seal-A-Cell sealer prior to GF Arm-R- Seal urethane topcoat where durability is needed. The Zinnser if for when I only want to wax afterwards.

typing – perhaps it was too early in the morning, but I said nothing about spraying SealCoat. Seal-Cell can be sprayed to but General doesn’t recommend it.

Sure more stages are better and more expensive guns are better. But they are also MORE EXPENSIVE. For thin material like Steve is talking about the 5500 is more than adequate, and at less than $300 on sale it’s a great option. If you want to play the bigger and finer is better game; than Earlex will lose every time. Fuji and Apollo kick their tail up and down the block everyday. Twice on Sunday. But at a significant cost.

If you’re spraying big$$$ finishes like auto,then a <$1000 system really isn’t going to be up to the task anyway. And a disposable pressure cup like 3m PPS is going to more than pay for itself because it’s going to squeeze out every last drop from the liner and save you cleanup time between primer, base, and topcoats as well. For larger, single material jobs like a kitchen repaint, Rich is correct. Pressure pot is the only way to fly.

So, if you’re on a budget, and will spray thin coatings like sealer and topcoats, 5500 is quite worthy.

Steve , pursue they latex and HVLP dream if you wish. But the 5500 is not going to work out well for you if you do. Especially your wallet.
