Paint spraying a ceiling


We are finishing our basement and will need to spray our exposed ceiling black. I was thinking of renting a sprayer locally but how hard is it to use the paint sprayers with latex paint? Is that something that is unrealistic to pick quick just for a ceiling?

Paint spraying a ceiling


If you are spraying an "open" ceiling(floor joists and what not) then spraying is about your only option. Rolling or brushing would take for ever and probably not get everything like a sprayer would. They are pretty easy to use, pretty much stick the hose in a bucket of paint and go to town. The most time consuming thing is masking off everything you don't want over spray on.

Paint spraying a ceiling


Sprayers are commonly used for spraying latex paint. How big is the ceiling? Spraying out a ceiling is easy for someone with spray experience, but you might be better off just rolling it.

Having said that...if you choose to rent the spray rig be sure to get thorough instructions from the rental place on how to use it. IF THE CEILING IS SHEETROCK: You generally want a 50% overlap on each pass, and it doesn't hurt to have someone come along right behind you with a roller (as long as it's not a popcorn ceiling), rolling in the same direction you are spraying.

I would probably give it 2 coats; the first one going wall-to-wall the length of the room, the second going wall-to-wall the width. It really depends on the direction of the room's primary light source (usually windows, but maybe not in a basement) as I like my final coat to be parallel to the light source (also true with rolling).

Just my 2 cents.

It's not Sheetrock. It's just my exposed joists under side of sub floor, pipes etc. I though rolling or using a brush would take forever. We were going to paint the ceiling before we painted any walls as a precaution. Just wasn't sure how hard they were to use and if I'd have to thin the paint.

Honestly, unless you want to spend a bunch of time learning to spray, mask, clean up a rig, deal with tip clogging etc- I would rent a painter with that spray rig- AKA- hire someone to do it.
It will be much less of a hassle.

What type of primer should I used on exposed ceiling with a mixture of galvanized pipes, wood joists, wires etc? Would an oil or latex primer be more ideal?

Just one more reason to hire a painter.
They would know for sure.

Paint spraying a ceiling


I tried contacting a few painters today. So far all I've heard is project is to small. Won't take it unless they paint walls too. I'm perfectly capable of painting walls though and don't want to hire that out too. What's wrong with trying to learn?

Nothing at all wrong with trying to learn.

Hard to believe you can't get someone to do it. Must be a rich town with lazy overpaid workers :-)

A typical airless sprayer moves a lot of paint fast - really, really, really fast. They can handle thick latex paints just fine. But it also creates an absolute fog storm, and by far the majority of your time will be spent masking, covering, and cleaning up.

An HVLP sprayer puts less paint in the air, and more on the surface, so the masking/covering chores won't be as hard. Or you could even try a LVLP sprayer, although it will be slower and you'll start to lose the advantage of a sprayer (speed.)

That question doesn't seem to make any sense - not sure what you're asking.

HVLP is different from airless. My local Sunbelt has this model for rent for $15/day.

That one claims to do latex paint without thinning. Some of the less powerful ones require latex to be thinned.

For spraying an open joist I think an HVLP will not push enough material- would take forever. Airless is the only way.
Id prime it with a good sealer like Zinsser 123, first a fairly fast coat so it wouldn't soak up forever then a thorough coat.
Lots of angles, one technique would be to walk through doing one angle, then next etc.
Wear a full carbon respirator, cover your body too.

Google How to spray with an airless and read, watch learn.

If the room is 20x 25 how many gallons would you estimate? Initially I just guested five as a starting point.

I would think 3-4 gallons, depending on how efficiently you sprayed (for example how much you oversprayed previous paint as you come at it from different angles.) There can be a lot of waste with airless sprayers, including what you clean from the sprayer/hose.
