HOW TO CLEAN A Titan Wagner or Graco Airless Paint Sprayer after oil based paints.

What happens here

The first step in flushing is to run the remaining oil-based primer from the hose. The presenter pours the used, dirty mineral spirits from a separate container into the 'dirty' bucket. He then transfers the sprayer's intake pump from the main primer can to the clean mineral spirits bucket. With the pressure setting lowered significantly (from 2200 PSI to a lower setting to avoid splattering), he runs the spray gun into the original primer can to reclaim as much of the oil-based primer as possible. He continues this until the primer starts to visibly thin out, indicating that mineral spirits are beginning to flush through. He emphasizes maintaining contact between the metal spray gun extension and the metal can to prevent static discharge, which could cause a fire or explosion with flammable solvents.

Goal: Remove the bulk of oil-based primer and ensure safety during flushing

What they say

Hide

right here in the grass. So, now I got about a half a gallon of mineral spirits in this clean bucket. I'm going to transfer my pump over to the bucket and begin the process of cycling it through my hose. So now my f my hose is full of the o the oilbased primer. So I want to run that out. I'm going to continue running the mineral spirits through here until I can see the mineral spirits or the the primer start to get thin and then I know the mineral spirits are starting to come through and then I'll start running it into my dirty bucket. One thing that's important to know is static dish static discharge could actually cause a fire or an explosion. So, in order um to not have it happen, I want to have my extension or my gun touching this metal can so a spark won't transfer from here to the metal can causing a fire explosion. So, I always like to keep my extension touching this can while I'm unloading the product and cleaning the sprayer.
