What is a VANEOMETER? #PaintersCare

What happens here

The host addresses the risks of cross-contamination when using the same paint sprayer for both oil-based and water-based paints. He explains that residual paint from one type can harden inside the sprayer (hoses, filters, prime valve), causing blockages and damaging components if a different type of paint is then introduced. He strongly advises against this practice unless a thorough, multi-step cleaning process (mineral spirits, acetone, fresh water) is performed, which is time-consuming and often impractical.

Goal: Understand the risks of cross-contamination and proper cleaning protocols for paint sprayers.

Tools and materials

  • Acetone — Cleaning sprayer components
  • Fresh Water — Final rinsing of sprayer
  • Mineral Spirits — Cleaning oil-based paint from sprayer
  • Paint Sprayer Graco — Discussing cleaning and maintenance

between spraying oil based paint and water based paint through one spray pump um highly highly not recommended so when you're using the same right they do but they clean up with different yo products so one cleans up with water one cleans up with if it's oil basically the process of contamination yeah cross contamination is what you get and every time you know you're switching back and forth what we found out is very quickly over time is the cross contamination starts to harden paint on the inside of the hose in also places where it starts to settle like in your intake tube it also starts to clogged filters really fast so your gun filters and your and your mana pool filters start to get clogged when you cross contaminate your pumps you have to have a really thorough thorough cleaning process in order to cross can not to have cross contamination and so for instance you know when you're cleaning out your pump and everything there's always a certain portions of the internal workings of the pumps they like the back of the filter they're very into the filter the water never goes on the manifold filter never goes completely all the way through it and so some paint using will sit back in there or your water so it's water now the next time you run oil-based paint you there it's gonna go through there it's gonna harden that you know that water or that paint that's in there or vice versa and orbitz oil-based paint that's left in there and the water goes in there hits it and so what happens over time you'll get your those bits and pieces and stuff settling getting hard starting to break free and it starts to clog your your prime valve or we started when we started using oil-based and water-based in the same pumps I can't tell you how many times we're going to take the thing prime valve out and little tiny hard pieces of paint we're getting stuck in the prime valve and when you take a prime valve apart that's you know it's a pain so is one of them harder on sprayers any other you don't know well like oil based products you know when you're cleaning with paint thinner and stuff and so the internal workings are never going to corrode and rust with these pumps they're stainless steel but we notice we took tore apart I'm a great go sprayer after only three weeks at using it and not using any type of pump protector or anything in it internal workings were corroded and rusted in a great go pump 395 so and that was water-based so you have to use like and cost protector we…
