Should I Thin Paint Before Spraying?

Yes, the latex paint does need to be thinned. Even though latex paint is water-based, it is thicker than the oil-based paint varieties. The thick latex paint needs to be thinned to be able to spray a fine mist of paint. Before applying your paint, it is a good idea to test out the paint's viscosity.

How do you know if paint is thin enough to spray?

Here's what you do:
  1. Pour the paint into the bucket.
  2. Add ½ cup of water for every gallon of paint.
  3. Mix thoroughly.
  4. Check the thickness by running the paint through a funnel. If it flows freely through the funnel, you know the paint is thinned enough.

Do I need to thin paint for airless sprayer?

They're extremely viscous, so whenever you spray them with a handheld, HVLP, or small airless sprayer, you need to thin them down. ... That's true when you're using anything other than a big airless unit. If you're using a handheld or HVLP system to paint, you're probably going to have to use as much as 20-30% water.
