howdy folks Kirk and J here with Kirk Giordano plastering today what I'm gonna show you folks
is we've got two adjacent buildings here and usually it's a garage and a house next to each
other well they had a hairline crack here and the contractor says gee Kirk what can you do
to prevent it my response is well we can put it in expansion corner joint but that is not going
to prevent it what the question should have been is what will you do to prevent it and here's some
of the things I've learned in 30 years and it's Kirk an engineer absolutely not Kirk's a stucco
guy a plastering contractor not an engineer or electrician or plumber anyway I was telling him
I said if you really want that structure not to hairline crack where it joins and he already knew
this too cuz I got here and I see it's done take your concrete drill holes in the foundation here
drill holes in here put some rebar in there tight and then use this youth doesn't see Jason knows
all this stuff use an epoxy to hold that rebar in there after you hold that rebar in there then you
lag bolt both buildings together where you have your studs lag bolt them in there then you take
the plywood from here and you put it over the plywood from the adjacent building now that's
about all you can do if we can go over this a hundred different ways but that's the best you
can do and then makes my job easier where the two structures are tied in now engineer engineer Klee
if that's a word they're structurally sound what I'm gonna do - is we went over the contractor and
I said well Jay Kirk what if I put some flashing here I said you have flashing that's about a foot
and a half no I've got same flash and you've got this stuff here the four - flash is nine inches I
said you know my vertical joints well we do paper and wire we'll do it where it's about a inch and
a foot and a half so I said here's what we'll do we'll take some paper it's about a two foot piece
of paper we'll shove it in here like so and we'll just leave a little bit exposed now that goes in a
foot in the house so that's what we're gonna do on this whole thing I'm gonna take that anything more
than a foot and a half it's overkill so we're in there a foot and a half here I'm gonna take
it all the way up we're gonna take some paper and crisscross it here and by the way guys any of you
contractors homeowners are gonna do windows and doors this is the way you do a tie out you you
break the paper you break the stucco out where you have the paper six inches and you have the
wire at least three inches that way we have a good waterproof sealant and we have a good overlap so
it won't get a hairline crack anyway well we're prepared to do right now is I'm gonna fish some
more paper in here about a foot and a half that's just and by the way I had to take out about an
hour to get all the rocks out of here but it can be done guys if you want to take the time out to
do it we're gonna go ahead and paper and wire this and then this big gap right here to say
gee whiz water's still gonna go in there yes it will but I'm gonna put a polyurethane caulking in
here either Sikaflex or rain buster in here that will seal and fuse this to it that's about when I
get that water perpend data I'm gonna stick this corner expansion in here will that stop it from
hairline cracking right there where the two meet may be but that's about the best fella can do if
you do all those things according to what what should be done so anyway we're going to put this
back together I'll show you it as we're doing it you folks have any questions of course you could
always email me here where I have foundation I'm gonna take my paper down past the mud seal
to about right here and then I'm gonna take my wire and concrete it in here we're going to put
a bonding agent and skim the whole thing that way everything blends in here there's a lot going on
here but try to simplify it and show you some of the most important things because people ask me
often Curt if you color coat my house will it stop that hairline cracking where the two buildings
join no the color coat won't do that that's gonna be hard enough to stop this hairline cracking with
everything done proper so when we get to that stage we'll show you how do it alright guys
we're at a stage now where I've fished that paper in here the longer the camera the better it is for
grabbing these guys right here and all you do is work your way up fish him out pull it out if you
come to fur nails hit it pull it pull back guys get that paper exposed get the wire out of the
way there's another tip if you guys are watching this more than likely you got to do this stuff
what I do is I'll take my gloves I'll cut the tips off see where I'm bleeding already but anyway now
now that we were all sealed in here I'm gonna put paper here and across here I've got a pipe here
what I'll generally do is make a little hook let's see so I'll come here and make a little u-shape
then I'll pull this guy underneath why we do this come on now get under there okay so now we don't
all we need to do is cover this mud seal guys we don't need to cover more than that we need to tie
it in we cut this out right there I'll show you mine one more piece folks I'm not certain what
the heck do from here I cut a piece of paper I generally use my roll tap that roll give
me a straight cut boom come on down put that guy right there now I'm gonna just go over everything
I want a tight corner there too guys and this could have wrapped around but I'm gonna double
my corners anyhow when I come to something like this now just put a straight cut fish in between
it and then with these penetrations we have to put caulking on every penetration what I'm doing here
is just making it a little bit prettier guys and then back the same way cut it here and because I
like to double double my corners and here I've got an expansion joint going it doesn't take
but a couple minutes to actually put a couple more layers of paper over the inner and outer
corner especially where I'm gonna be nailing that expansion joint so I will put another piece right
here is this code and do you know but when I do my expansion joint there I want to make sure that
we're watertight okay guys we're on my second tube of caulking that's a big gap in here and
what we do is we squeeze it in there we just keep squeezing then we go through a couple more tubes
that's okay caulking is cheap let me just keep filling it up guys keep going back and forth I'm
sure we'll burn this tube out also but this is not really what what I was meaning to show you
folks okay just stick that guy there this is what I want to show you guys now when I work Union back
in the early eighties I used to hang a lot of these things and I did I get different responses
from different contractors some guys would say Kirk cut the wire first then install it some guys
would say put it on top of the wire some guys would say oh I heard every contradiction known
to man as far as these if you google it you'll be there all night trying to figure out which way is
the best way as far as on top of the wire on the wood itself on the or on the paper itself there's
no one there's no code for this particular thing I'm doing I'm doing this just as a well I told the
contractor this would help a little bit so that's why I'm doing this all right guys this is the way
I prefer to do it I'm gonna put this on here and by the way two guys I could nail this on I could
use my gun I don't have very much of a flange so let me see if I can catch it a hair get in there
got it this is called an expansion joint and yes you could use an inner outer you can use them on
solid walls there's just no limit to expansion joints the last thing I'm gonna do after I get
this is we take our handy dandy half hammer and push this wire in right here guys I already did
it but we want to push it in my new wire is gonna go from here on top of here and that's how we get
that's about it's as close as we can get to all the requirements necessary in order to do the best
we can so we won't get a hairline crack anyhow guys I'm gonna go ahead and wire this and want
to bother done I'll show you the completion of it okay guys we are at the completion of this no
video on laughs would be complete unless I showed you the last thing the role of wires in a circular
motion and there is no difference between how you put the wire on this way is backwards follow the
groove usually not always and now it's furred out meaning this is against the wall here these every
six inches it's red and it furs it away from the wall so my last piece is gonna go right in here
and I'm basically using a staple gun furry nails are outdated you can use fur and off but you'll
be here forever why use fur nails when the wires salford doesn't make much sense anyway guys that's
that you can do on a corner detail where it's a Jace from house to house or garage to house or
any of those other kind of details my name is Kirk Jason on the camera and of course he actually did
a lot of this we thank you for watching and as usual folks we'll see you guys on the next one.
