While a bleeder will help atomize the paint, if I understand correctly, it also creates less pressure behind the paint, since some air is always escaping So here's my thinking, based on zero experience: The paint is also supposed to go on with ONE pass, which is an extra problem.īut the good part: This is multispec paint, and it's being applied to 3-dimensional acoustic diffusors, so the one thing it does NOT have to be is flat & smooth. The paint is NOT supposed to be thinned, though I will take a chance and thin it a little bit, and maybe also add a little Floetrol. I will be spraying very heavy Multispec latex, with a 9.5 psi 4-stage turbine, so I'm already on the edge. I need to decide if I should use a bleeder or a non-bleeder for this job. Well, I still have one big decision to make, maybe you guys can help if you have the time to absorb this: Last edited by Allan Speers 12-02-2021 at 1:52 PM.
MULTISPEC PAINT MODS
It might have worked, but when I added up the cost of all the mods I needed to do, it made sense to just buy a different turbine. There's also this interesting "HVCLP Adaptor" dingus, which claims to increase pressure at the gun on marginal systems: I found a thread adapter but it was crazy expensive. Unfortunately for me, the Turbinaire MiniPro I was going to use has a 7/8" outlet, whereas that Apollo valve (and almost all other turbines) use 3/4". To safely use a non-bleeder gun (like the Accuspray 10, 19C, etc) on a turbine that was designed for a bleeder, most folks recommend adding something like the Apollo relief valve to the turbine's output connector: But I'm just guessing on how they work. I guess maybe these open when the motor starts to get hot, to cool it, but close again so as to keep maximum pressure to the pot for as much as possible.
Jason, you are correct, but evidently the more expensive turbines are designed for non-bleeder guns, and thus have some sort of air escape valve internally. I assume most good guns can do the same, with the appropriate inlet plugs. Capspray's guns can easily be switched from bleeder to non -bleeder, evidently for this exact reason. But of course then you need an extra-powerful turbine. Interestingly, I read that bleeder guns can actually be better for atomizing thick latex, due to how the air moves through the pot.
MULTISPEC PAINT PLUS
Plus I have the Turbinaire CS bleeder, also set up with large flow components. I'll also have 2 non-bleed guns to try (The Accu 10 and the Maxum II) if I get a large needle-cap set for the latter. Yes, I will definitely experiment & practice first. Last edited by Allan Speers 12-01-2021 at 2:05 AM. I also see that in a 2012 post here, member Mike Mesner mentions that he had an adapter from Turbinaire to allow him to use a non-bleeder gun with his Turbinaire system.Īre those still available, from some other manufacturer? (I assume it's just some kind of bleeder valve that would go inline with the hose, correct? I read that on older Fuji turbines you can actually drill a hole in them, to let air always pass over the motor, but of course mine is not a Fuji. I do have a 93-025 regulator, (Which is called the 3600 in the users manual, for some reason) but AFAIK that's for use with a compressor, correct? If this is purely a non-bleed gun system, is there a way I can use it with my turbine? Is that what it's for? To let air escape when using a turbine that has no relief valve? The pot itself has what seems to be a pressure relief knob. This is a non-bleeder type, correct? (I am somewhat clueless right now about HVLP) I bought the Accuspray #10 separately, and again have never used it. My Turbinaire system is designed for a bleeder gun.

I'd rather not thin the paint as that could compromise the "multispec" look, but I will if I have to. They recommend a 4-stage system, but that is out of the question. And I have to spray several gallons of it. Unfortunately the stuff I'm about to spray is Rustoleum Multispec, which is water-based but very thick.
This turbine is only 3-stage, rated for 130 CFM 6 PSI. I also have a huge assortment of tips & needles for the Accuspray gun.
MULTISPEC PAINT SERIES
I also have an Accuspray Series 10 gun, with the mini regulator & gauge. The basic system is a Turbinaire Minipro Plus, with the original CX gun. I've been away from doing projects for a long, long time.ĭoing a project this week which requires my using an HVLP system which I bought long ago, and never used.
