I have a Fuji unit but I haven't tried latex. They say latex is hard to use with HVLP.

I've not had problems with overspray. I would cover anything within 4 feet of where you are spraying and you should be fine.

Steve,

I have the larger Apollo unit, I believe they are very similar.
That said, what I do know about my Apollo is that I would have to use a larger opening/needle in the gun.

As to the covering, personally I always assume Mr. Murphy is stalking me, :o :o :o,    so how much more will a little plastic cost?
(you could always curtain off a corridor to work in.)

ps. be careful of any venting, either central air or heating you have going.......which you might consider shutting down for the operation.

Ok, thanks

btw, I have the Fuji 4 with the standard needle (it s the blue)

Fuji site say i can spray latex with it otherwise for large surface i need to buy new needle (just for that I wonder !)

so covering about four feet , should be enough ! , maybe what I might do is to use the gun to cover corners and hard to reach places and use a roller for the rest !

do you thinki should prime with some shellac???.... (i paint white latex over it)

I have the Apollo 800 and I seem to get a lot of over spray when using poly or laquer.  It seems to fog my garage pretty well. I'm probably doing something wrong, I've tried adjusting flow and pressure and still seems that material is being wasted.  I have not shot latex with it.

Ji Steverunner,

HVLP systems are around 80% efficient, meaning 80% of what comes out of the gun winds up on the work piece and 20% goes into the air as overspray.  If you are shooting into box corners like an in place bookshelf you will have more overspray, perhaps more like 30 to 40% while shooting into those corners.  Plan accordingly.  White latex must be thinned to shoot well and the best products are those made for that purpose (often called flow control products at paint stores).  Distilled water will work but white is notorious for being hard to one coat so the manufacturers often lace their products with way more titanium oxide just to help coverage.  Overspray will get everywhere but will dry quickly in the air so a lot of your mess will be dried small dust like particles.  You will need a way to evacuate the area spraying that much material per coat so you should look into renting the kinds of blowers meant for drying out flood damaged rooms, preferably one with a long large diameter hose to get the exhaust to and out of a basement window.  Erect plastic walls, floor and ceiling around the project and buy a good quality full face mask designed for organic solvents plus a particulate filter.  Calculate the amount of paint required from the coverage info on the can and add 30% for the amount of material that won't make it onto the project.  Know that 30% of that total will wind up in the air an in your lungs and eyes if you really well protected.

Hope this helps.

   Steve,

          i have the Graco 4900, but that's not why i called. Anyway, as for spraying latex paint in your finished basment... Remove all electronics you don't want to be really dusty when your done. Drop/mask the heck outta everything you would prefer not to have atomized paint particulates on...in other words be major careful the stuff flies everywhere, if you have valuables remove them.perhaps the idea of spraying a little in the corners and rolling the rest is the best idea.Also, for those in the know latex paint needs to be reduced 10% in order to reduce viscosity to flow thru the sprayer I use paint-mate some use flo-trol some use water it's cheapest and seems to work fine.Keep it outta the HVAC sytem too.
                                                                                                                                              Dan/painter

Over here (in holland) what we refer to as latex is a paint exclusively used to paint walls. It has a matte finish
and it would look real ugly on anything but a wall.
Is the latex you mention a waterbased paint suited for wooden surfaces?

Just curious

There are many white coating that are not latex...try reading www.target.com and look at their white coatings. More expensive but sprayable.
   I would rather rent an airless sprayer for the day or weekend and coat the units in white latex.  Buy a couple of plastic drop clothes and cover enverything and spray. You will be surprised how fast you can be done, primer and finished coats and a super fine finish. Good paint stores rent them as do the big box.
