We are using Sherwin-Williams PVA drywall sealer & primer. We will then use 3 seperate paint products, in their respective rooms/surfaces.

We have:
Emerald interior satin, in light Grey.
Super Paint interior satin, dark Grey
Eminence ceiling paint

the machine kit came with a 15" extention tip, a 4' flex whip, a 515 orifice spray tip, 25' hose, gun, Airless machine and pump armor storage solution. 

I am a skilled trade worker, in many construction/maintenance trades.

I have always painted with rollers & brushes. this job, being so large, 1st time surface coat, and our personal custom build forever farmhouse, I wanted to save some time, and do it right.

people I have spoken to say spray all surfaces primer with machine. then, use machine for ceiling paint only, but roller paint the walls.

anyone who I mention spraying walls to, says I need to roller behind sprayer... that kind of defeats the purpose of spraying, in my opinion.

why does no one use it to spray the walls, and if they do, what is purpose of rolling them after?

also, any general tips on use would be greatly appreciated.

I have watched some YouTube videos, and I have a brain, so I get the basic concept, but I am looking for additional firsthand experience. also, any specific cautions or suggestions.

>why does nobidy use it in interior walls other than ceiling?
Cause it looks like shit, is rough as shit, takes just as much time when you have to tape off anything and don't just have an open fresh construction environment. Yeah essay, spray four coats and then run your hand over it. Feel that? That's shit.

is it a bad idea to PRIME the walls with the sprayer?

you say painting walls with sprayer would leave a rough finish. it stands to reason that priming the walls would also leave a rough finish.

will the topcoat of paint carry the rough primer texture through, or cover and smooth it?

I'm about to spray the inside of my pole barn within probably the next couple weeks. Not sure of the colors yet. Probably white ceiling, off-white or gray walls, and white trim. With all the casings around the poles, it's just too much to cut in by hand.
In my experience, when spraying interiors, it's always back rolled after to give it that texture from the roller. I don't know if I'm going to bother or not. Maybe just on the top coat, idk yet. Depends how the sprayed finish looks.

It's a nice machine. The smaller handheld Gracos have a plastic piston that drives the entire pump. These fail frequently. Plus they're similar in price and need refilled three times on one ceiling. 
I just sprayed a house with the Magnum. It's a lower power version and I send paint out pretty much full blast on the dial. I carry a roller in case of overspray, but I'm not back rolling the entire house. I've already had to skim coat and drywall the entire place because it was all textured plaster. Back rolling gives you guaranteed uniform texture. Your airless sprayers are great for no bs throwing out paint, but they will not be surefire with fine trim and cabs. Generally on cabinets I'm competing with factory baked on candy shells. The best I can get straight out of an airless will have some texture unless I polish it down with wet sanding. 
It's definitely nice to pull paint straight out of the bucket onto the walls. I didn't have any overspray issues over the last entire house. We went ahead and painted before trim doors and floors.
--- 2592068
Like all spraying try to maintain uniform distance as you go. Watch your starts and stops. I will feather out on stops. Everything you don't want painted anywhere close needs to be masked. I tried to spray walls once stopping 3ft down and overspray still climbs and viginettes the ceiling paint. The airless sprayers will leave quite a bit of paint dust that drifts down. It is easily wiped off, but in the world of interior construction people want you to do their maid service as well. 
PVA is perfectly fine to run. They're supposed to shoot poly and tuff hide as well.

spraying walls is complete nonsense unless you dont have doors, windows, cabinets, or anything else in the way

>>2592053
This anon gets to the heart of the issue, which is that what makes airless attractive for fast high volume painting is also its biggest weakness:

>airless sprayers are great for no bs throwing out paint

>It's definitely nice to pull paint straight out of the bucket onto the walls

The nature of how they literally throw paint is optimized for using paint with little to no conditioning that mitigates texture issues; try to make the paint less likely to hold that texture and flow better and starts to sag at the volume its put out at, try to lessen that volume via tip size or standing back and the paint starts drying on its way to the wall, and holds texture again.

Back rolling lets you even the texture in a way thats not really possible with spray equipment in a room, in a booth you can shoot an object's surfaces straight on as you move around it, the shape of a room means corners can never be approached this way and the resulting air currents interfere with the application. 

Doing it doesn't defeat the purpose of an airless, backrolling doesn't involve the steps of loading the roller and applying its contents to the wall and repeating that process over and over, which are most of the time involved with roller application. It's like having to roll a pre-made pie crust to the thickness your recipe calls for vs making one from scratch.

2/2

Bottom line is that airless alone sacrifices finish quality for speed of application by less skilled labor who are blowing paint all day, every day in production environments likevtract housing. Even really skilled painters who know the ins and outs of how to tweak paints for best finish results run up hard againt their limitations and either use something else altogether or use another method to get better surface results.

If you want a relatively cheap and easy system for better quality finishes and some speed advantage, look into HVLP...not only is the raw finish quality better than airless, they're better suited for an individual homeowner situation where you aren't applying dozens of gallons of paint a week and might need to do more than paint just walls.
--- 2592103
these things are retarded. 

you are going to use 50 percent more paint, thats a shit load of money

you will not save any time after you account for the masking

you now have to wear a respirator

oh and now that your are done spraying you still have to roll it or it will look like dog shit,
--- 2592134
>>2591938
Sure, I guess you could spray it for primer. But just make sure to sand the walls and hand sand the edges before you start topcoating.
--- 2592157

sprayed entire house interior yesterday. it took less than 2 hours. that's 1380 sqft of ceiling, and also all of the walls. no idea how many total sqft that is.

primered every surface, walls and ceiling. then came back and painted ceiling with sherwin eminence ceiling paint.

looks good.

rate the machine 10/10

wife will go out there today and start painting walls with roller.

only primer used sprayer. paint will be done with roller and brush.

>>2592602
wore respirator for 95% of the time. the 10 foot section between the corner and the doorway shown in photo was the last 5 minutes of the day. I doubt that I or the dog inhaled enough latex to come near the damage done to my lungs during my *former* 22 years of smoking cigarettes.

Ok anon, I have the x5, it can barely spray thick stuff like duration, but great for all the things you listed. But I had to upgrade to the low pressure green tips, keeps the spray pattern more consistent. Put paper down on any finish floor. Then you should prime everything, then do ceiling, spray trim, then just cut and roll the walls like normal. This minimizes blue taping everything. I like texture on walls from a roller. I bought a power roller for it and I love it, rolled ten gallons with minimal effort. Lots of people hate them, I understand why, but you really need to be rolling 10 gallons to make it worthwhile. Good luck anon

Pro paint contractor here. If I'm doing interior work, I pretty much only break out the sprayer for cabinets or staining. Thing about spraying walls is you need to back roll anyways, just roll the walls, it's not that hard or time consuming. I find a sprayer to be more useful for exterior work.
--- 2592877
>>2592871
thank you!

awesome input.

we will probably be painting the exterior of our current house when we put it on the market in a month or two. we just painted it last spring, but want it to look fresh for sale.

I had planned on using the x5 for that, but good to hear from pro perspective.

when we rollered exterior last spring it was a 3 day project. we did scrape and Caulk and some minor repairs as well, but definitely a good 2 solid days of painting. 

hope to make a 2 hour touch up with the x5.
--- 2592901
You forgot a negative with the sprayer.
Cleaning is so much of a pain in the ass that I just threw mine out when done. No need to store that fucker either.

What people don't understand is that sprayers aren't the end all be all. I initially bought it to paint walls that had 4x8 sheets of wainscoting for walls instead of drywall. Worked great and didn't have to worry about the crevices, x5 paid for itself. But the prep work/cleanup is tedious at first but eventually gets quicker. I've only used the thing 10 times in 4 years. But it really comes in handy if the situation is right

Can ‘t you use it as a pressure washer for your car? I think they are over 100 psi.
--- 2593179
>>2592901
Not just a pain in the ass but so much paint gets wasted since the hose walls retain it and it all has to be flushed out.

Not a big deal if you are painting house after house after house with multiple 5 gal buckets of the same color, but just to get the paint from the bucket to the tip commits you to tossing $10-20 in paint down the drain during cleanup no matter what.
--- 2593189

Good point. I looked at home depot the other day and you can buy a gallon of paint for over 100 smackaroonies! WTF. I can get blown for less tan that.
--- 2593379
>>2593179
Yeah, there's a reason you typically only see pros with sprayers, and like I said, I'd rather just use a roller and a brush if I can. Prep can be a huge pain in the ass, cleaning is a pain in the ass, maintenance is a pain in the ass, but if you're already booked out for exterior jobs for the warm months, they're definitely handy.

>Bought Picrel. Building A House. Painting Interior Ourselves. Never Used One Before

I never used one before and had great results.
I got the extra 50' of line and an extra tip incase it wore out. It didn't. I ran about 40 gallons thru it no issues. Make sure to clean it really well after each use and use the pump armor fluid storage fluid when done. I also got an extension tip for doing far away places like the roof eves. Very pleased with it.

Clean paint is a key, don't get any shit in the paint, you don't wanted any clogged spray nozzles. 

be rested, its a work out. Take some anti inflammatory pills before you start so you can work thru the pain.

I've paid 80 for cabinet paint before. I know Sherwin wasn't giving me a contractor discount. I'm also not entirely convinced of noticeable jumps in quality past a certain price point. Other box stores sell brands owned by Sherwin for much cheaper per gallon.
--- 2593955
>>2593951
i only use durations by sherwin williams, its the best shit there is. Its is 60 a gallon. But if you need to do a touch up 7 years later that shit is going to match.

Also here is how a friend of mine got the discount. He did actually used to be a painter and I was helping him paint his house. He just walked in and said hey Im about to buy 2 grand worth of stuff. EIther give me the contractor rate or I will just go to the next town over. They gave it to him and, if they say no I will just keep calling different stores untill I find one that will give it to me. They gave him the discount.

$80/ gal doesn't even cover the cost of primer for truly high end interior paints, Fine Paints of Europe gets $135 for 2.5 l of primer and $155/ 2.5 l of their EUROLUX Interior Matte...

Their oil based line is $175/2.5 l or just over $260/ gal. And you'll need thinner, $25/ qt. or $60/gal.but you have to buy 4 gallons at a time to get that price and it "cannot be shipped into: California, Connecticut, Maryland, Michigan, New Hampshire, New York, Rhode Island, Utah, Delaware and Maricopa County, Arizona."

Is it worth it? Not to most people but it meets quality and consistency standards that nothing at SW or its competitors can match, and if you want something like a dead flat sheen you have to go with something made to those standards. It's overkill for most people, just like a Rolls Royce with carefully bookmatched wooden paneling inserts lovingly massaged to a rich glow is overkill.

And as paints go, that's not even close to being expensive, pic related.

When spraying the ceiling spray cut the corners first going at a steady pace then fill in the rest. I highly recommend going back with a roller on ceilings if you want uniformity and if you ever need to do a touch up on them they will blend better. Paint wise use pva for primer, promar 400 on ceilings, cashmere or promar 400 for the walls and super paint for trim. If you’re selling you don’t need the high end stuff. Take it from someone who has work as a painter for 14yrs and house flipper for 8.
--- 2594721
i was advised this is good for outside if you need to worry about over spray, but i suppose it can be used inside as well

Much like Moon shoes this things are too good to be true. They are dog shit you can never really get the right amount of paint on the roller. Normal rolling is still faster and lighter than this monstrosity

just a question,

if you know the hose contain 1 gallon of paint couldn't you hang the pump into a bucket with 2/3 gallon of water and use the water to pump out the rest of the paint.

a bit of paint is lost as a safety margin so you wont spray water on the wall. 

BTW its done this way in robotic car painting, the controller calculates the amount of paint needed to finish the car and then pumps water/surfacant into the hose to empty it.
only a few spoons of paint are lost when the robot flushes its hoses after the job. then the next color of paint is pumped into the hose.
--- 2599174
>>2599066
It doesn't work as much like this as you'd think. The water you draw in seems to mix in the motor. So it's pretty guaranteed to waste at least half of the leftover.
