Hey guys - I’m looking at spraying some exterior aluminum residential windows/frames and am curious what product you have had success with.

They are the factory windows from the late 90s and have never been painted previously. I’m leaning towards pressure wash, SW emerald urethane with Emulsabond mixed in first coat

Thanks all

Emerald Urethane would work well in that application. Be sure to scuff the surface with a sotchbrite pad before painting. I would not recommend EmulsaBond additive.

Don’t know if you are still working on this project, but did this same thing yesterday. *We had to spray them in place.

Heres what we did:

1. cleaned metal parts on windows (used 409 spray, no reason, just had some on hand).
2. Scuffed surface using maroon scouring pad.
3. Rinsed w/ clean water.
4. Masked-off window and surrounding areas.
5. Sprayed w/ Graco 9.5 and #3 fluid set.
6. Used SW Emerald Urethane (package consistency -no thinning).

edit: I would be curious to know how others would typically handle this. We don’t get a lot of calls for this type of work.

Looks great would basically do the same other than we use worn fine grit sponges rather than scotch brite. Minimal masking and spray HVLP. Working on a similar job right now big 10ft windows and have to scrape silicone off every single one first and pray for the best.

#3 needle is a bit small for emerald straight from the can though looks like you had a good pattern.

They’ve reformulated it recently.
I tried it thinned and un-thinned, and felt I was getting good atomization without thinning.

I would also do about the same. I wonder whether you've ever considered just allowing overspray onto the glass, coming behind later to razor it off? It's generally fast and easy. I've never done that but I ask just because I saw some cabinet guys do it once. They showed up with a glass transom with the whole thing sprayed out. Installed and then scraped the glass clean with razors. Only might or might not be a time saver.

How is the flow rate with the #3? Seems like it would be coming out pretty slow, no? Have you sprayed with #5? Will be spraying the same UTE on this job in about a month
I was getting good coverage with two passes: one pass get the inside bevel, and the second pass to get the the outside profile. I was focused on getting good atomization, and less concerned about paint flow.

Only tried #3 this time.
In the past I tried a #4, which definitely sprayed more product, but the atomization was not nearly as fine.

I'd rather tape. I don't mind taping/masking. I will admit that I did not know what to do with the channel between the sides of the upper window and the casing.

Some of those windows would be a real PITA to access without a lift or scaffold. All can be done, but would be very slow going. Other than the scenery and wildlife, I don't envy you @cocomonkeynuts

It's too late to get a lift, by the time one is able to make it up here there will be snow. For now ladder work and finish with a lift next year. And yes it is a PITA I spend a lot more time scraping old silicone off than anything else but I'm hourly on this one so:coffee:

Btw all the lumber is finished with shipnshore
