Oil Paint Cleanout

This is definitely quite a remedial question, but since we started our business three years ago, we have never used anything other than latex paints. It's becoming increasingly clear that if we're going to continue growing, we're going to need to expand the paint lineup. Cleaning out the machine is obviously not a science, I'm not worried about getting it done properly. I would just like to hear a few of your processes. In my mind, I picture myself going through a large quantity of product during clean out and color changes. Can you confirm this and / or offer any expertise to streamline this process with as little waste as possible? Thanks in advance.

i just remove the paint bucket and place a clean bucket with mineral spirits on the machine and flush the paint out with the mineral spirits. clean the filter and make sure the filter bowl is clean at the same time. that's about it. if your going to go back and forth between oil and latex I would advise against any "hot" thinners. anything in your machine will soften and release causing issues, none of them good.

You will have nightmares changing a latex machine to an oil based machine and back and forth. As NC said the solvent in the paint will soften up the paint on the suction hose no matter how much you clean it. You really are better off sticking to one type of paint or get extra machines for the oil based

That is the best advice you will ever receive. Another option that helps is have another pickup tube, hose and elbow for each type of paint.

Here we have water based paints, toulene, or acetone. I have never had trouble switching between water and toulene, but the acetone and water is a real mess. To make the switch, you have flush the machine with toulene. Since there is not much asphalt here, the toulene paints are the best for me.

You shouldn't be having any problems between water base and acetone, you can mix acetone into a water based paint to speed up drying since acetone is less hydrophobic than toluene.

Have ever done this change. If you mix actetone paint and water based is turns to a goo and clogs you lower pump and elbow. Then you have to clean the goo out with the paint still in the machine.

Yes. When you clean the line with acetone there shouldn't be any problem as acetone itself can be used in both types of paint. At least I would assume he is cleaning out the fist type of paint first.

I'd pay good money to watch you perform this action on your machines as you say and see what happens! LOL It's quite simple. You clean the Solvent/Acetone based paints with Toluene followed by flushing and storing with mineral spirits! IF you are using strictly latex, then Water, Hot or Cold Water, can be used to clean. For a good clean, putting hot water with soap helps! Then you store with the Pump armor that Sherwin Williams or Graco sells! Take care of your machines and they will take care of you! As far as just switching a machine back and forth between Solvent/Oil base to Waterborne/Latex if you use acetone YOU WILL HAVE PROBLEMS!

I agree with having dedicated machines for latex and oil, and if you can afford it, one of each for each color for both solvent and waterborne. (8 - 3900's) For me I'd prefer to have more machines dedicated to solvent/oil base because the product is better and you can charge more.

experience goes a long way in machine maintenance. I switch between oil and latex all the time with no issues, but ive been at this for 30+ years and know exactly what im doing as I would imagine straightline does also. how is the end product better if you have properly functioning machines? you lost me here. you charge more because you have more machines? do I need my boots for this thread?

As I'm retired so you won't be spending any money unless you want to watch me work the remote for the tv. Acetone won't cause an issue but toluene can. Acetone can be mixed with a water based paint because it will mix with water and doesn't break up the surfactants that surround the acrylic particles of the resin, toluene doesn't mix with water and does break up the surfactants. I wouldn't spend extra money on mineral spirits, it's unnecessary. If you're storing for awhile just us used motor oil.
