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

Watch on YouTube

What happens here

Place the sprayer's intake pump (also referred to as the pump or hose that draws material) into the 'clean' bucket containing fresh mineral spirits. Engage the sprayer to begin cycling the mineral spirits through the hose and out of the gun. Direct the output of the spray gun into the 'dirty' bucket. Watch the discharge carefully; you will see the oil-based primer or paint being flushed out, gradually thinning until only clear mineral spirits are visible. It is critical to keep the metal extension of the spray gun touching the metal 'dirty' bucket (or another grounded metal can) during this process to prevent static discharge, which could lead to a fire or explosion.

Goal: Remove oil-based primer from the sprayer's hose and gun

Tools and materials

  • Airless Paint Sprayer — Operating the pump and spraying cleaning solution
  • Clean Bucket with Mineral Spirits — Supplying clean mineral spirits to the pump
  • Dirty Bucket — Collecting flushed dirty primer and mineral spirits
  • Spray Gun with Extension — Directing the discharge during flushing

What they say

Hide

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.
