Painting Plan


If we are talking about a lot of trim to be painted, then I would go ahead and spray and not worry about the overspray flashing after you paint the walls. If there isn't much trim to be done, then i would just brush instead.

Good Luck!

Spraying has its place. The last time my California home was painted it was sprayed and looked great but I was selling it. I have mentioned before I usually sub out spray work. No color changes. It was empty until I leased furniture on a short term basis to stage and sell it.

Wagner would have the consumer believe they can spray anything with a Harbor Freight handheld thing, or a cheap toy of their own making. It does not work that way.

My direct experience is in the fine and commercial art world and I would never trust just rinsing out $400 worth of airbrush on rare instances where I sprayed acrylic latex with just water. Even so I went through a fair number of needles and spray tips on a regular basis.
come on SDS If your not smart enough to remove or protect furniture in that situation you shouldn't be painting and as for the rugs, how would you protect them from splatters and spills when using brush and roller? And Wagner and airless are 2 different animals as is air brushing.
Let me say up front spraying is not, let me repeat NOT, the answer in every situation. But in a lot of cases it is an easy and very good alternative.
As with paint and tools in the last few years spray equipment has come a long way. With the new tips and guns you can control overspray, not eliminate, a lot better. Just as with the new tapes and masking gear it is nothing like it used to be.
Sorry I said I didn't want to start an argument so I'm done.

There is a big difference in sprayer types, with regard to overspray. You mention a 213 tip, so I assume you're talking about an airless sprayer. They can send massive amounts of paint into the air and surrounding areas. With a HVLP sprayer it's a different story. They send more like tiny little globs of paint rather than a mist, and it also comes out slower. It's funny to watch how slow you have to go with some of those sprayers in the infomercials compared to airless. But HVLP (better quality than the infomercials hopefully) are more suitable for interior use (in an occupied house.)

Just to clarify, with the new fine finish tips you can go down to a 2" fan add a whip hose and you don't get massive overspray, in fact you can use it to paint trim in place. And my experience with HVLP is unless you are willing to put out over a grand or more to get a 4 or 5 stage turbine they are only good for small projects. You have to thin the paint so much the heat from the turbine dries the paint too fast and you get really uneven sheen. Also the cheap ones should work for finishes other than paint since they are a lot thinner.
These FF (fine finish tips) are green and have their own tip guard. When you purchase an airless sprayer they usually come with a 517 regular tip. This means a 10" fan and the hole is .017 diamater this tip puts out a large amount of paint, whice is good if you are painting a house, but not so good for close work. These tips are all made by Graco.
What I use on exteriors is the new Titan whice has 2 tips in 1 You can shoot a 10" or 12" fan, then when you get in close like to a window or soffit you turn it 90 and you get a 6" fan. Turn it another 90 and it will unplug the nozzle.

Painting Plan


since we are talking about tips... I tried a 113, 213, and 313 each at enough pressure to get a good spray pattern. Each tip had a width at least double what it should have been at 12" from the surface and sprayed WAY too much paint. No matter how fast I moved I had runs. I ended up having to spray all the trim and doors with a 113 tip at about 18-20 inches away or else the paint would run. What did I do wrong?

I used a Graco Magnum DX with Graco tips and Behr semi-gloss paint.

Thanks,

David

Did you thin your paint? With airless you should not thin at all.
Did you have the pressure up too high?
Were these new tips or used?
Any of these could have caused your problem, plus moving too slow, HVLP and some of the other types of sprayers you need to move slowly with airless you need to move along pretty good.
David I don't know if you are familiar with the way tips are sized or not. The first number in the tip size, say 5, you double that and it will give you your fan size. In this instance it would be a 10" fan at 12" from say the wall. The next number say 13 is in thousands the size of the orifice. Let me say here that there is most definitely a learning curve.
My suggestions would be don't thin, check your pressure, go to appliance store get some large pieces of cardboard and practice your speed, and for trim and doors I really like the FF tips. Hope this helps.

Sorry for the slow reply, we've been super busy. I did not thin the paint. I speculated that the pressure was too high but any lower and I was leaving tails. The tips were brand new and I was moving as fast as I could with out spraying paint everywhere. As far as the tip sizing goes, I am familiar. The 213 was easily spraying 6+inches wide and the paint went on too thick even moving fast. I ended up using a 113 from 18 to 20 inches away from the surface and sprayed light coats. I got it done and it looks great but I knew there was something wrong and wanted to figure it out. I think next time I am going to try a 211 or a FF tip like you suggested.
