Topic tags/keywords: earlex 5500 spray finish spraying poly

So, I have an Earlex 5500 and I’m spraying General Finished water based poly (gloss white). I’ve sprayed this before with what I thought was success but it was on a VERY small project. Well today I am spraying a much larger project and I’m spraying it in the basement. I put up some thin plastic paper on the walls and tarp on the ground. It’s obviously not air tight but I thought, for the most part, it would be decent enough. I went to spray and here are my issues:

1) I don’t know if I’m not dialing in the gun properly or what, but because the turbine pushes air through the gun and out the nozzle at all times, I feel like I’m getting A LOT of overspray. I can see the white mist getting pushed out and onto the plastic. I had set the gun to basically “closed” from the front nozzle end and from the rear where you adjust the amount of paint and i only opened each relatively slightly and I’m using the round spray pattern as I’m spraying baby gates which have thin spindles so I thought it made sense.

2) There is a layer of white dust EVERYWHERE in my basement now. It settled VERY quickly and I’m going to have a ton of cleanup to do after I’m done spraying. How do I prevent this further aside from the obvious, spraying in a dedicated booth or outside.

Any insight as to how these issues are dealt with normally would be greatly appreciated. Spraying is relatively painless but if I have to deal with these issues each time I spray indoors I’m going to have to switch over to brushing as this is not ideal for my situation…

Generally, people use a good exhaust fan to pull the over spray out of the room. Another option is to make a portable, folding 3 walled structure with a partial roof and a fan centered in the center wall. Set it up in your garage with the garage door open. Put a furnace filter in front of the fan to keep the spray off the fan blades. Jeff Jewitt, and probably others, has described this arrangement in one of his books IIRC.

Art, I do have his book and saw the setup but didn’t get a chance to do it for this project. Is there a particular type of filter I need? I know they have different MIRV ratings etc but which would be best for this application? The cheap 4 pack so it can be easily replaced without costing too much? But then there is the question of that being enough to keep the paint off the blades…

Matt, I use furnace filters that come in a 3 pack. I don’t recall the brand but they are nothing special. The reason is that the spray will clog the filter, so I use cheap ones and replace them often. I used 2 filters initially, but didn’t think I was getting enough draw with a 24” window box fan, so now I only use 1 filter at a time. If the fan dies I am not too concerned because it was only about $20 at the borg maybe 4 years ago.

Thank you Art, I’ll give it a shot next time I’m spraying. I’m also going to construct the booth that Jeff jewitt describes in his book for next time as well.
