howdy folks Kirk and J here with Kirk Giordano plastering today what I want to show you folks
is a question I've gotten asked quite a few times especially with architects expansion joints now
I did a video with expansion inner corners 2 months ago it got a bunch of hit people asking
what's the best way to put them on the outside and I explained it on email and I typed slow so
I thought I'd explain it visually and show you because this is a lot faster for me first of all
we're working for him fella tom with iron wood construction and tom is a contractor engineer
he decides make repairs special specializing in a Berkeley Oakland area where houses are fallen
he he rebuilt the foundation put like 20 tiers rebar and all kinds of bars and back of this wall
to shore it up now I was here yesterday we were a laughing this and Tom of course comes out and
says hey Kirk I want to put some expansion joints in and I thought you would you architects are all
alike you always want an expansion joint says Kirk I'm an engineer okay same difference but
anyhow I said we don't need any expansion joints on this project because we have windows and doors
wearing when I when I took my test and when I work Union we do a lot of expansion joints now
25 years ago when I got my license it was every 10 feet without a door or an opening we would put in
expansion joints for commercial what Jay Jay just took his license what three or four years ago what
what is it okay well that's 144 square feet it's the same anyhow I told him you don't need any but
in an engineer he said well gee can you put a few anyhow so I thought okay how do you want them tom
that's my question this is what do you mean you're the stucco guy you put you know how to put them
I said oh man I know how to put them and I'll put them every which way I've taken seven eighths and
put them directly on paper then we've taken the wire we've cut the wire and write it in I've taken
1/2 inch like this and put them over the wire which technically gives you the seven eighths
anyhow I said how do you want to because I don't want to do this twice and he says well you're the
professional you do it now for you folks out there who might clicked on this and want to know how to
do expansion joints what I you can call the lath and plaster Institute you can go to google and man
you can spend forever there where you can do what I did I haven't put any on in a few years since I
was doing a commercial project I called Charlie Charlie's at close building materials located
in Hayward I said Charlie you've been in business since 1967 like 40 years you sell the stuff what
are your requirements and Charlie is just a fountain of knowledge he impressed the crap
out of me he didn't know who I was I just said I'm a stucco guy what's the proper way to aling
these and Charlie says ok what you want to do is you want to do your wire stretch out your wires
and then you want to go half it you want to place it directly on top and I said Charlie I'm going to
use a pneumatic staple gun is that okay he says Kirk or he didn't call me Kirk as he didn't know
who I was he said listen they just did a bunch of tests in LA simulating earthquake damage and
it proven that if you staple it it lasts a lot longer when they simulated earthquake damage if
you if you put this on say we put this on and we use nails the heads of the nails popped off so
he says not only do you put it on the wire but you use staples to attach it and Charlie knows
he went on to explain commercial 40 years ago how they used to do it if you're going over block or
brick 3/8 of an inch instead of half half-inch any information you guys need and again Charlie
didn't know me from Adam but he was willing to take his time out and tell me exactly how
current codes are today and what he recommends Charlie had closed building materials inhalers
anyway I want to show you what we did over here we already did an expansion joint that's an old
style window here we got a new new modern window what I'll generally do guys is we put one at the
top up there and we're just going to follow it down I'm going to put one more on this what I'll
generally do guys hopefully I got some air left in my gun because I turn the compressor off because
it happens to start each time I get ready to show this theirs easiest way guys you just lay the top
on and it should line itself out unless you were through it in a truck and they got all bent up and
I've done that where we thrown it in the truck and just threw all kinds of crap in it alright
once you got it where the top is put a couple staples put you level on it now and level it
out most of the times are accurate but not all of the time by the way guys you can't cut this stuff
for you best way to cut if you're doing a whole bunch of these I would have brought my chop saw
with a metal blade and just cut them because it doesn't clean if you're trying to use these good
luck I mean I do it all the time but I put my bad end say like on the bottom here I'm going
to put my bad in because they're going to build a deck here so the bad end won't matter anyhow
you staple it off guys look at it make sure it's true plumb and level these are called expansions
of control joints are they necessary no not on this particular house we're doing it for
because old Tom wants them and we do what we're told usually anyhow guys I'm sure I might have
missed a few things about expansion joints but oh here's another thing this has tape over it
so when we mud it the mud won't go in here but if it didn't have tape like in the old days we
just take a trial and scrape it right out so after we do our two coach or even a color then we just
scrape pull the tape off right here just peel it right off and again they're expansions or control
joints you can call it either way they control the movement of the house anyhow guys my name is
Kirk I'm with kirk Giordano plastering, I thank you for watching if you like what we do should
subscribe please as usual Jay and I thank you for watching and we'll see you guys on the next one
you
