I bought a Magnum airless paint sprayer to paint the exterior of a house. I'll be using latex paint (probably Behr from Home Depot).

I'm wondering which quality of paint would work best in it. Behr paints are available in three quality tiers, and I know from experience that paying a little more for the second or third tier is worth it. The paint is much less runny, which makes it easier to work with when brushing and rolling.

But with the sprayer, I'm wondering if it would actually be better to have a cheaper, runnier paint. It seems like a thicker paint would have a harder time coming through the sprayer.

Thanks in advance for any tips on this.

    I have not used an airless sprayer, but I do know that some people use a product called Floetrol as an additive to make spraying some paints easier. As you're researching paint and spraying, understand what these additives are best used for and if they can help you. – JPhi1618 Mar 21 '18 at 13:25
  • I have a budget brand airless paint sprayer and it has no trouble with really thick 'outdoor' latex paints. I don't think I've ever even turned it up to full power yet, so I doubt you'd need to deliberately choose a runnier paint. – brhans Mar 21 '18 at 14:39
  • Are you sure it's really runnier...maybe...not..stirred..fully? "Runny" is not a factor on quality. My aircraft grade paint is quite runny even mixed for brush, and it outlasts Rustoleum by 6:1. – Harper Mar 21 '18 at 17:32
  • Don't think it is the quality as much as the type. When I rented a sprayer the dealer warned me not to use oil based. – Marinaio Apr 2 '18 at 20:59

I use an airless sprayer and all I do is thin out my paint with either water for latex or paint thinner for oil base. I use Glidden paint and have sprayed them all, Oil base, Latex, Acrylic Enamel, and every sheen as well, and really the only difference I have seen is using oil base, I use the thinner because it helps the sprayer not work as hard. I have a Magnum sprayer also and been using it for over 3 years now. Make certain you tear the gun down and clean it thoroughly every time after spraying paint. You'll thank me for this if you keep it clean clean clean......and strain your paint.. that's a must. this will help the internal filter on your sprayer. those things get expensive if you have to keep replacing.

Could try a quart of each type of paint and see how well each one does on a wall painted a darker color. I've heard Olympic brand paint at Lowes does pretty well and Ace hardware's line of paint works pretty well. Walmart sells recycled paint online for 11/gal as well that I've had pretty good results with.
