hi guys Kirk and Jay here with Kirk Giordano plastering several weeks ago we did a video
with commercial style stucco work so I had a lot of questions in that video I want to try
to answer a couple of those if I can right now what we're doing is when I mentioned commercial
it's the rules are different to residential and now I'll show you a little bit about what we're
doing if you can take it down here this is three point four mesh wire and the decks had an issue
so they're taking all the doors out putting a new deck and what my buddy is doing is he is putting
it all back together so I agreed to help him out I owe them a little bit of time in what's that Santa
Giordano pays his debt anyhow well what you first have to do is find your studs so all these little
red marks are studs over here with this three point four mesh it's kind of a drag because we
got a hang screed so we got to screw everything in with Dewalt screw guns or whatever type of
gun you want to use to go in the metal here it's not wood here I can tell by the structu laughs and
struck the last is pretty good stuff I can tell that since they're using this there has to have
a different kind of structure and it did because I just peeked under there one of the see right here
we have gypsum board and over here we have dens glass dens glasses fire ratio it's yellow it's
fire and water proof but you can't just stucco over it you still have to do the two layers of
paper and wire what are what are the questions a couple weeks ago fella says well what's all that
plastic all this plastic right here there's a lot of plastic under the paper back thirty years ago
when I was Union I remember having to put that what that plastic simply means is you put your
plastic and you let it hang about here then you put your drip screed on we do all the cement work
over the course of a month sometimes two and at the end of the job we cut right under that drip
screed and that plastic holds all the cement so it doesn't get in the corners the plastic is just
for that guys great question though anyhow let me take you guys around here and show you some
of this stuff again struck the lath here three point four mesh here and what what we do is we're
using templates templates just a piece of wood put piece here put a piece here find your studs
then you set set this underneath and in back of the paper now we screw into the studs then we put
two more layers of paper under this put new wire and put it down and that's real time-consuming
we don't have the luxury of the wood a few floors below they do have that luxury where it's all wood
instead of the steel studs and den this glass anyhow moving right along here you can see what
all these windows grace on grace on grace they pulled them all out they put them back they use
the existing grace here and now we're tying the the new to the existing newsy flashing on the top
stainless steel let's see we got one here alright give you an example of what we're doing here this
is pretty pretty time-consuming and but absolutely necessary they've already put this piece of I core
right here over their own flashing and by the way we even had to have a guy come here and use
a towel they scraped all this down with a tool than a towel to get all the residue off otherwise
this grace won't stick to it and after say what they have here is our job is to not only counter
it their flanges here but what we're doing is we're sticking the grace to the grace on top of
this z flashing and then the two layers of paper actually go under here you fish it back and forth
all the way up as far as you can get it here then you cut it right here in this way there could be
a pinhole or a screw hole somewhere here that they myth this way if they're safe rather than
sorry and the fella what are the fellas says men you guys sure burn through a lot of that grace is
that necessary well the people who are redoing this I think it's absolutely necessary because
tenants here they got to move somewhere while all this workers in progress so this stuff is
cheap compared to problems what I was telling folks here is I'm given some instructions is we
have a key in here in this frame right here some of the guys when I first got here we're putting
it right here and that's a guy overlap the frame a little bit say if you just look at this and you
figure a half-inch over the frame stick it here this way you can go into that key there we have
it so that this area back in this key here is done really well I'll share once more you kind
of look at it and go over the frame about a half inch that way that key gets done really well and
again the two layers go under here it's a it's a pretty time-consuming thing guys but this is
just laughs it's still a couple coats to cement and then to make matters even more difficult is
inner corners we got inner and outer corners with expansion joints now we can go 7/8 of an
inch these expansion joints here are seven eight seven inches commercial guys the rules change
with commercial to residential normally I did a video way back when and I was showing half-inch
expansion joint ons at three no kailath or Davis lath but for commercial again the rules kind of
changed so what we're doing is we're placing a 7/8 expansion joint directly over the paper and
wire then the three point four goes up to that a lot of ways to do expansion guys and lastly I'll
just show you this one last thing here back up in this corner J okay here's the real tricky part for
us it's a bit of a drag they went with 7/8 right here expansion so we've got to match that all the
inner corners on all the decks everywhere this this building is loaded with expansions inner
and outer ever you name it it has it so we we we graced the corners anytime you're going to put a
inner expansion joy and we just basically follow that and the scuppers again these
are we're putting a Jay trim around the scuppers mighty easy five inches up five and a quarter up
seven wide notch out your bottom it's on this drip screen real easy I can not just the three corners
on one solid piece in about two minutes so anyway guys some of those questions you have feel free to
email me and it asked anything I doubt many of you viewers are doing commercial work but we used to
do a lot of it when I was Union way back early 80s anyhow guys my name is Kirk I'm with Kirk Giordano
plastering Jason on the camera and as usual folks we thank you for watching this I guess you call
it instruction on how to do commercial stucco and as usual guys we'll see on the next one
you
