Spencer Bates Posted December 21, 2011 Report Share Posted December 21, 2011 I'm in the process of finishing a project and I'm using my new earlex 5500. I have already sanded down the first coat of finish because of this but I keep getting a weird splattering texture. I thought it might just flow out nice and even but it remains in the dry finish (oil based paint, thinned with acetone). I am wondering what I'm doing wrong... I'm trying to get a nice perfect surface but it isn't happening for me... Any thoughts? Quote Link to comment Share on other sites More sharing options...
dwacker Posted December 21, 2011 Report Share Posted December 21, 2011 Sounds like mixing issues. What is the viscosity? Don Quote Link to comment Share on other sites More sharing options...
Spencer Bates Posted December 22, 2011 Author Report Share Posted December 22, 2011 I just thinned a batch of it down about 15% and it runs through the viscosity cup in about 65 seconds. I have a 1mm needle as well as a 2.5mm. I was previously using the 1mm... Quote Link to comment Share on other sites More sharing options...
dwacker Posted December 22, 2011 Report Share Posted December 22, 2011 The 5500 comes with a generic guideline sort of viscosity cup and it is pretty much useless. I would get yourself a real viscosity cup. The machine is really more so designed to spray a fence or outdoor furniture so getting a perfect finish is going to require that your finish is thinned just right. Their generic viscosity is not going to cut it if you're looking for a furniture smooth finish. Don Quote Link to comment Share on other sites More sharing options...
AceHoleInOne Posted December 22, 2011 Report Share Posted December 22, 2011 Try the larger needle and nozzle. 1.0 is for thinner type finishes. -Ace- Quote Link to comment Share on other sites More sharing options...
dwacker Posted December 22, 2011 Report Share Posted December 22, 2011 I asked a buddy about your viscosity cup. He says it fairly close to a ford #4. So at 65 you are way to thick. If its thinned down as far as you can go then you need a bigger needle. With a pressure cup you should be about 1.8-2.5 Don Quote Link to comment Share on other sites More sharing options...
chicks82 Posted December 27, 2011 Report Share Posted December 27, 2011 the 5500 does not like to spray thick material. it will orange peel on you almost every time. what kind of finish are you using? Quote Link to comment Share on other sites More sharing options...
