Mdub, that's a good point. Thing is I've been spraying trim packs and doors with a 310 and never had any sort of problem. It was just with breakthrough and cabinet coat. I even tried a 212 and it did it. I think it's a good idea though to try it with a 415 or something bigger just to see what would happen. Dont know if I'd be able to spray cabinets with something that big though.

I had a time with some breakthrough a week or so ago with a 212ff. I strained the paint and the situation vastly improved, although my gun was giving me spitting fits by the end of it. (Gun is about shot, so I ordered a new one for next time)

I've never used an x08 tip for any sort of paint. Lacquer, maybe. I used one once for some semi transparent deck stain.

Despite the spitting, the cabinets turned out pretty well for painted oak with no grain fill.Worn-out packings and fingering pattern?-20200208_142207_1582267671407.jpg

We added the crown before painting and there were new counters, backsplash and flooring coming afterwards. I'm interested to see the final outcome, as it's my first set of blue cabs.

Anyway, these were done with a 212ff on a titan 440i. I'm guessing around 2000psi, but lacking a pressure readout, I usually have the dial on the border of yellow and green for breakthrough.

It turns out both my gun and pump filters were in a bad way, but I hadn't used the thing in so long I didn't have any spares handy. I suspect that caused some of the issues. I had 60 mesh on the pump and 100 on the gun.

I can't see how packings could cause what you described, unless they were completely shot. The pump should be able to easily keep around 2000 with pretty worn packings. If they were that bad, the pump would be running all the time just sitting there and paint would be coming from somewhere it shouldn't.

Anyway, I just posted all this mess because I just did the same exact thing with the same exact equipment.

Looks like some fine finishing Paramount. Nice to see others shooting cabinets and with the good old 440. Thanks for the input too. One thing you mentioned I haven't considered as the gun filter, I'm running a white which I believe is a 60. Maybe I'll look into a finer filter there.

I was shooting some ppg Ultra hide on a rental turn around today, and just for the sake of science I pulled out the 308 tip. Came out looking great. So I'm not sure what the deal is with the Breakthrough and cabinet coat but there is something going on with my setup when it comes to those products.

I think someone on here has mentioned that those urethanized products in particular don't like going through the smaller orifices. There may be something to that, because other standard latex paints seem to go through it all right. Maybe I'll set up with a bigger tip and try some breakthrough when I get a chance.

Since I ordered a new gun and filters for the 440i, I decided to use it to spray some crown on our current project.

New gun, new 60 mesh on the pump and new 100 mesh on the gun.

This was ppg speedhide sg. I strained it and the seal grip that I used for primer. Existing finish looked to be satin impervo or maybe some pratt and lambert oil.

We scuffed it up lightly with sanding sponges and wiped down with damp microfiber cloth.

Night and day difference with the new gun and filters. I used a 210ff. I usually wouldn't bother masking and spraying such a small thing, but it was a terrible built up crown with dentils.

The one noticable thing that I had somewhat forgotten is the 440 has a bit more pulsation than I am used to. My go to airlesscos are pretty on target when you set the pressure. That said, it worked ok for what I was using it for. I had the pressure dial slightly below the yellow/green spot on the dial. If I'm recalling correctly, this sprayer has never beenWorn-out packings and fingering pattern?-20200224_205115_1582621034853.jpg re-packed. It is pretty rarely used and may have a couple thousand gallons max run through it in 8+ years.

The pics are only the main lobby, but we had more of the same crown in other areas that we were able to knock out this evening/night.


Banker's hours are great, unless you are working in banks opposite banker's hours.

*I have never divined why some pictures are sideways and some aren't, but it's 4am and I'm not that worried about it at the moment.

Just had to take my titan apart yesterday cuz it got a clog under the ball from the crap! Even w/ the red fine filter mesh & straining before spray it still makes its way in...& its always right when you get into the swing of things

I have an airless that currently whines and runs on when under higher pressures. I assume that it because dried paint is not allowing the ball the seal properly. When I crank it to a lower pressure it doesn't run on and the piston is quiet. I'm not sure how to fix it. I'm glad that it can be fixed however.

Time for a repack they will include new upper and lower ball in the kit. Make sure to inspect the lower ball seat when you go to repack. They are reversible if one side is worn.

Yep it can always be fixed -Maybe time to take it in & get repacked?

If you wanna take it apart & aren’t sure how just youtube “model + stuck ball” or “model + wining under high pressure” , there’s prolly someone thats done a video on how to repair it.

Mine is super simple- just a friction wire clamp holding the tube in, a few bolts,and the entire siphon area is apart. Always grease up the O rings with specific lube after clean too.

Sometimes the just ball gets stuck. Have you tried giving that area a tap w/ a wrench or rubber mallet to see if makes a difference?

I can usually tell its gunna happen when the pressure feels abnormal & it takes longer to prime. Tapping it only works for awhile tho, eventually you’ll need to get it serviced or take it apart & clean out whatever’s causing it to stick.

If that doesn't work,get a bigger wrench or mallet. Increase tool size until problem is resolved!
