spray painter question
Wilmoe
I am in a confused state as to which way to go. My wife suggests using a paint
brush but I know there must be a power tool.
I am painting cedar shake siding with exterior primer and latex top coat. I
have a Wagner 505 airless sprayer with diaphram pump that seems to have given
up. I suspect the gun but can't prove it for under $70. And I could be wrong.
This unit does not seem to be sold anymore so I am hesitant to invest $$. I
also have a Sears (probably Wagner) airless hand held sprayer. Fortunately it
doesn't work either. The noise is unbearable. For both of these units I tried
thinning the paint. In fact I thinned beyond the paint manufacturer's
recommendation.
What can any of you say about the air compressor run guns? Porter Cable even
has a couple of gravity feed units where most of the others are siphon feed. I
have a PC CF2600 2HP 6 gal. pancake compressor whose manual states a 50% duty
cycle, anything in excess of running 30 minutes per hour is "misuse" of the
compressor. Will this type of gun exceed by compressors capacity?. Has anyone
used a gravity fed gun? I loaned my compressor to a guy that used it to spray
texture material and it exceeded the 50% duty cycle to be sure. The texture gun
was gravity fed but I think texture mud is a different animal from latex paint.
Plus the hopper was probably two gallons.
Also. are even the $300-$500 airless piston pumps (Graco I think is one brand)
as noisy as those hand held beasts? Maybe that is the benefit of diaphram over
piston?
Any suggestions would be appreciated.
Thanks

Listen to your wife, I've been to the movie.
I lived in a house with cedar shake siding for over 25 years, forget how
many times I painted it, but it was a bunch.
If you want to spray, you need some serious equipment, not toys.
Something like a DeVilbiss JGA with a remote pressure pot, for example.
About $400-$500 depending on how good a shopper you are.
That JGA needs at least 15 SCFM to operate properly.
That means a 5HP, 2 cyl compressor with at least a 60 gallon tank, add
another $700-$900 to the pot.
240V electrical connections, hoses, regulators, etc, another $150-$200.
Now you are approaching $1,500 and no paint on the house yet.
You will repaint about every 5-7 years if you live in the rust belt like I
did.
If you spend $50 for a good 4" brush, buy a new one every time you paint, it
will take you 150 years to amortize a $1,500 investment.
Ya can't get there from here.

......and in reply I say!:
Those little airless guns are crap. They are noisy, they spit, they
jam. I believe that airless spray stuff starts to get really usable at
pro level (US$1000?)
Any spray system needs _meticulous_ cleaning every time you use it.
Unless used fairly frequently, they will get gunked even then!
The compressor you have will struggle to keep up with any decent air
gun, but you may be able to use the little store-bought jobs (results
unknown!). Don't believe the air requirements they tell you. They will
be very optimistic. Your compressor will give maybe 5-8CFM at the
lower pressures most guns work at.
As far as 30 minutes in the hour, simply don't use it more than that!
Use a roller or brush. The job takes a bit longer, but you don;t have
to worry about wind, and cleaning up is a lot easier, with mistakes
being a lot less disasterous.

Buy or rent an airless pump. It's the only way to spray latex IMO, and you
can put a ton of paint on in a real short period of time (so much that if
your not watching you will go through a five very quickly). You can also
get extensions for spraying up under the eaves......no ladder work! And
with the right spray tips (and there's plenty) you can spray just about
anything you want, e.g., varnish, lacquer, oil.

My recommendation is to go and rent a REAL airless spray setup--the kind
that's designed to work with 5 gallon buckets of paint and will spray
just about anything. As rental tools go, they tend to be kind of
expensive, but the lack of hassle is well worth the cost, and it'll be
way cheaper than buying one. And how often are you going to need one?
Rent it.

As far as I can tell the ONLY folks that LIKE the cheap,
Wagner airless paint gun are the guys that actually do the
commercials. When I started looking for a sprayer, I spent some
time checking out the Net, and, found very few positive remarks.
In general, if you have to thin paint to get it to spray, that is
a BAD thing, as paint is a fairly complicated chemical mixture.
Thinning it will cause serious problems with its resistance to
slumping, adhesion, protective abilities and life.

Hum...I suspect that while a good paint gun could be run by
your compressor, I fear that the speed and results will not be happy.

I had a couple of buildings (one 10x18 and one 20x40) to paint
this summer, and, I picked up a Graco pressurized paint sprayer from a
pawn shop for $300. It was "pre-painted" in that it was covered by
a thick layer of white paint. However, it cleaned up very nicely, and
once I put a new nozzle on the gun, worked great. It does have some
pressure problems, in that it will only go up to about 1500 psi
(instead of the 2200 or so it is rated for). However, for the latex
paint I was spraying, this was NOT a problem. I REALLY like and
recommend either buying or renting one of these units for house-sized
jobs, as you will end up spending more time moving the ladder than you
will actually putting paint on. It does a GREAT job of laying down a
smooth, even band of paint, with minimal overspray and, will do it
fast. The unit I have is rated a 1/2 gallon of paint a MINUTE -
which, if I could move that fast, would be about 250 square feet
per minute. All told, to shoot the smaller building with primer
(covering the inside, and outside) took me a couple of hours.
shooting the finish coat on the outside surfaces alone took
about 45 minutes. It would have taken longer had I been a bit
neater, but, not much.
In short (too late, I can hear you saying), Rent one of
the commercial units for the weekend, make sure you have enough
paint to do the job; make sure you have quick access set up
for it, and, it should go VERY easily. I would recommend
taping up the windows, etc, with duct tape and plastic the
day before you paint. It will make life simpler.

LMAO! That is a VERY good point. Actually, one of
the more amusing bits about these units is the number of stickers
and warnings they have all over them and in the paperwork with them
talking about how easy it is to squirt big chunks of paint under
the skin. It may LOOK like a small cut, but, there will be a
big ball of paint under there, and, if you hit it JUST right,
it can blow right through your hand.
I LIKE it!

Heh heh heh. It's a good thing OSHA hasn't cut them
back to a "safe 10psi max" pressure, isn't it?

I'm painting a 1000 sf house, inside and out. I originally rented
a Graco Nova machine at $60/day from Sherwin Williams, but decided it was
more cost effective to buy a sprayer. I bought a Graco Magnum XR5
at Home Depot for $398, along with a 30-inch extension wand.
It's great -- pumps something like a quart a minute, has a 12-inch wide
dispersion pattern, and works nicely.
These things spray so fast you have to move very quickly. I can do a
10x16 foot room, including the ceiling, in about ten minutes.
To get this sort of performance out of a compressor-driven machine you'll
need a very big compressor, and you'd probably need to thin the paint.
I recommend you buy an airless sprayer instead.
Cleanup on these machines is a pain -- that takes a lot longer than the
actual spraying does. Also, the machine compresses at 3,000 psi.
You want to keep the spray tip pointed away from you at all times --
apparently it can inject paint into your veins, which results in surgery
and sometimes amputation.

Oh yea...I meant to mention that as ANOTHER benefit
of an airless sprayer....there is almost NO overspray. Some
huge percentage of the spray ends up on the wall - like 95%
or so. What little does show up does not show up as a fine
mist (as can happen with air-type guns) and float. Instead
it is more like little globules that bounce off the surface
and fall directly to the ground.

Yep, painting time is about zip, the prep time is now the limiting
factor. We need the equivalent of the airless sprayer for masking tape
and drop cloths. :-)
I got that sprayer at HD a couple of years ago during Christmas when
they had their 10% off everything sale. Used it to paint a stucco
fence. Finished the whole thing, inside and out in one morning.
Limiting function after prep was moving the paint and sprayer and
refilling the buckets. Andrew's right though, cleanup is a royal pain.

Reminds of my old man telling me about when air-powered grease guns
first came out. Guys kept clearing blocked tips with their fingers,
and then needing the finger removed. The grease simply went into the
tissue.
...and some very unpleasant stories about what guys did with air hoses
when they first came out too...fatal

I believe that Life should always have four dimensions,
not just three. My wife agrees but cannot understand
that it takes time to achieve this.

: it out yet.
Not as bad as I expected -- I get close to 400 sf coverage per gallon.
As Dave Mundt's post said, most of the overspray falls to the ground as
teeny pellets. However, if you're spraying a whole room, the air wil get
pretty thick with paint mist.
You should wear a good respirator with both organic vapor cartridges and
the cotton (I think) prefilters. After the first two rooms I
took out the prefilters and saw they were coated with paint, so switch 'em
often.
I also wore a diposable Tyvek overall (not critical), and eye goggles.
That was the worst part -- when painting the ceiling some paint droplets
will fall into your eyes, so these are important, but they get covered up
fast enough that you can't see what you're doing all that well. Covering
them with saran wrap helped (and changing the saran wrap often).
