Need to dilute house paint to use in Preval Sprayer

My friend and I are painting some electrical conduit PVC for the spot lights we are putting up on his house. His house is being painted first.

The paint sample is Sherwin Williams Color to Go Acrylic Latex (pics)

We will be applying this paint (after the parts are primed) with the Preval Sprayer system (pics).

Requesting some guidance on the proper dilution mixture ratio and what dilution agent to use (I think water but not sure).

Does anyone know anything about the quality of the Preval spray system?

Suggestions, alternatives (other than a different type paint or base of paint) or comments please

I find PVC very hard to keep straight and use EMT for most of my conduit work on a house.

Why not put the conduit up first and paint the whole thing at once ?
You would use water to thin the paint but go real easy as the paint will run very easily on a smooth surface like PVC.

he wants to use pvc instead of EMT.
He wants to paint the conduit first so that the house is painted and then the conduit put up afterwards so all surfaces under the conduit etc are painted and so he does not have to go up on a ladder and paint by hand under the conduit etc.

long story this is what he wants to do

PVC is dirty pipe. Make sure it's good and clean or the paint won't stick well. I'd almost recommend a quick sanding with a light emery cloth or maybe a scotchbrite pad.

PVC primer will be needed, then just paint with brush.

If you try to thin out to use in sprayer it will never cover.

When painting PVC with latex you need to prep the PVC first to insure that the paint will adhere. This can be done by scuff sanding, using a liquid deglosser or adding Flood's EmulsaBond to the first coat of latex. If you have to thin the paint to get it to atomize you'll have to apply multiple coats, letting it tack up between coats. IMO it would be better to apply the paint uncut with a mini roller.

This is the primer I have, it's old, probably 25 years, cant even read the name but company is Graham/Hooker and looks like they are out of business now.

Ive used it on vinyl pipes, shutters, and front door side light trim.

Note, it's solvent based, not latex, so it etches the vinyl for the paint to stick.

NEVER had an issue with paint sticking to this!

Need to find something comparable, check out a real paint store, they have the real stuff.
