Weather and or Moisture Resistant Barrier, retrofit window, stucco wall
Howdy guys and gals, at this home the homeowner had retrofit windows that have a 2 inch flange that is supposed to cover any imperfection when install correctly. We improvised to stop any water that could seep into the area where the flange meets the framework.

Hey Kirk thanks as always. This is the best practical use of Z flashing I've seen. Great tip and very much appreciated.

After getting tired of working with SikaFlex with my hands and dreading the clean up after, I found that using the back of a plastic spoon to work in the caulking works great! I go to the 99 cent store and buy a box of small spoons, large spoons, and spoons for soup for larger gaps to work in and smooth out the caulking. Results come out great, good time saver, and I just toss the spoon out after I'm done and no clean up! Groovy hat by the way! -Mark from San Diego
Hey bud, I usually use my discarded paper or any stick lying around. But for this video I used my fingers to prove a point. Good thing I ware work cloths. I like the spoon idea because I always have them in my truck and they will flex. Thanks for the tip.
Have a great day!

Hey mittsdad. I somehow lost your comment. After a fella called me and said about 10 of the flanges were leaking 15 years ago I decided the flanges are so brittle that it was best to caulk for strength and waterproofing and simply install the Z flash on top.
Have a great day!

Wouldn't you want to leave the bottom un-caulked to allow for drainage? I'd presume the old window frames water plane is still good, you just put plywood over it?
Evening Jacob Johnson, under normal circumstance I don't caulk bottoms of windows that have been installed properly.
But with either old existing wood windows or in this case no flashing prior to window installations I have no choice, no caulking it would leak.
Have a brood evening

My house has no sheathing. It's just paper, wire and stucco, with the window put in on top of the raw opening, Amazingly enough, no rot. But how would I approach flashing from this aspect. The stucco is very hard to peel back without destroying it. How much of an overlap should I go for? Thanks.
Hello Scott Johnson, when I first stated there was no shear wall on homes as a rule it wasn't required until 1976?
But anyhow you only have the space of one and a half inches to work with to stay on a stud then youre back in between which we call the stud field. it takes a ton of time to break out just right.
A good tip is a lot of caulking on the tie ins.
Cheers!

I have a client who has a home constructed from a product called Cempo, which is a building block consisting of recycled concrete and styrofoam. These blocks are approximately 18" tall, 48" long and 12" thick with hollow cells similar to CMU. These blocks were stacked in 4 foot lifts and grouted with concrete and rebar in the cells. The windows were installed without head flashing, but they are recessed into the stucco wall approximately 1.5". The stucco was applied directly over the Cempo without any building paper. Further, the parapet walls are rounded, and were not flashed before or after the stucco was applied. How can the windows be flashed, and any suggestions on flashing the parapet?
HI David Thomas, the windows should have had the flashing installed prior to the window installations, If this can't be done at this time, the other option is to apply sikaflex polyurethane caulking to the surrounds and or use a peel and stick membrane.

I discovered something a long time ago when working with Sikkaflex. If you get a cheap $2 bottle of Isopropyl Alcohol from local drugstore, it's very easy to clean your hands of sikkaflex. If you dip your finger in it, you can smooth the sikka flex without it sticking to your fingers. If you cut yourself on the job, boom, same Isopropyl alcohol 70% or 90% doesn't matter, whatever is cheapest.
Hi Kimosabe, this is a good tip,,
I used to clean the stucco off my body with this Isopropy Alcohol, bad idea, now I use absolute or the purest vodka I can find.
Best wishes,

Is it standard to have to use so much caulking? Does the window Co. intend it to be installed this way? I haven't replaced a window or know much about this sort of thing, it just seems to me that there is an easier and more cost efficient way to do this. I mean no disrespect. Great video's BTW
Evening Diamond Dude,
excellent question, glad you asked.
The amount of Caulking was much more than I would typically use for windows properly installed.
Generally with a typical window installation,with a proper nail on flange, you place your paper or peel and stick membrane crosses the bottom of the window, then place the vertical sides over the bottom flashing with the paper next to the sides, the top of the window is then flashed with a plastic or metal Z flashing.
This same procedure should be done when installing inserts or retrofit windows also.
On this fellas home the flashing was left out or missed,
We improvised by installing the flashing after the retrofits were installed and used a caulking design to fuse the paper to the flange as we had to improvise and make certain they would not leak.
Best wishes,

Why would one wear a black hat in this weather?
Evening, it was in the truck so I hired it,
cheers,

Because he can
Wow, what a hack.
Howdy, Garrett, who told you?
Just the first name is all I ask or was it the hat?
Cheers,

Hey Kirk. Why didn't you put any peel and stick membrane on the sides and underneath the window fin like in the bottom. As always thanks for your super educational videos.
Good Morning Leonardo, dude, good question, it was too hot, I felt the sticky part would have hit the wall and stuck tight to avoid this fight I used two layers of paper to get as far as I could and caulked the meeting of paper to the window flange.

Kirk Giordano plastering Inc. So if it wouldn't be for the heat it could of be done? Thanks for you fast response.
Good Morning Dude, absolutely, what this video does not show nor did I explain was it was over 100 degrees in the shade.
I would have had to try and shimmy the peal and stick back and forth until it reached the frames, it would not have happened, a mans got to understand his materials as well as extream heat.

I bought instruction from stodoys and I build it very very cheap.
We're the windows installed over the old frames, jump frame install?
Good am Kirk love watching your videos, am learning a lot.. so thank 4 that..
If you go by code, the way you are doing it , it’s totally wrong.
Question Kirk. Should you leave some weep holes at the bottom of the window in case water gets behind the tar paper then it has a way to leave and not back up into the window opening?
Good shit!
Hey Kirk! Hope all is well I was watching this video of yours and realized something. I remember you mentioning I’m another video that you don’t usually put any sealant below any windows. The last video I saw you sealing only the top of the window and not the sides.
Thanks again for always uploading great videos!
Y wouldn’t you take those windows out stucco wall then retrofit with caulking on top of stucco no leaks garuanteed
