Hello folks, Kirk here with Kirk Giordano plastering.
how many of you homeowners have seen this lath before how many of you know the name
of it I don't even know the name of it we call it a redwood resin-treated tongue and groove
or keyed exterior sheathing it was come out in the late 1800s to about 1920 1925.
I read online that this one fella started calling it his in 1920 but it's been used a lot sooner
than that anyway how do you tie this in now the homeowner said Kirk how you gonna do that then the
contractor said Kirk how you're gonna do that and I thought you know there's a lot of good examples
on these two windows I've showed this before but not in such great detail because you see
right here we got a humongous hole and right here the wood is compromised I mean there's a big hole
here generally you have a 30-pound felt behind this then this board goes on top of that so the
contractor said well what do we do here and I said man you gotta tear the whole thing off and
he looked at me so it's all you're [ __ ] me no I'm just kidding man anyway I'll show you guys
what we do these keys these are keys right here we like them clean when we can find them clean but
they don't know we don't always have that luxury say for this big hole right here what we do is
we clean out that key you can blow it you can do whatever you want get it out of it I'm just going
to show you a small section and then we're gonna go to another window that I've already done okay
we take our two layers and we go up as high as we can staple that off now we find our key this
key right here is the one I'm gonna use because that's the lowest one we kind of get a feel for
it we take a brand new blade on a sharp utility knife I just put a new blade in here the blade
is dull it'd be here forever okay now that we've got that done you see our wood is in a key it's
in the key right there do I need to pop staples not really but okay we got a hole right here what
am I gonna do that hole I'm gonna put I'm tall urethane call in that hole so as I caulk this
piece here in this particular caulking it is it's a polyurethane caulking and it's it's a real drag
if you get it on your hands because unlike the cheaper ones that you can clean up with water
you need denature alcohol or thinner but you get what you pay for this stuff will last forever once
it's covered here what I'm gonna do is I'm gonna take a half a tube of this stuff fill this up then
I'm gonna paper from here to here and put another bead of caulking here I'll show you over here cuz
we're done okay guys I'll show you with a window I already did all right I just did a spot over
there and now of course you have to cover the entire thing otherwise water will go in those
little holes now I spent about 15 minutes right here just brushing these keys out with with this
and the contractor actually got rid of the keys here why do you do that because he thought well if
you get rid of the keys isn't it easier to caulk that and yes and no because how's it going buddy
we can do this what we want to do is seal this tar paper to the wood lath in itself and again
this caulking I'm using is also a sealant it and here's everything to whatever you're using it will
here bricks to bricks even that's how strong this stuff is and where you have the key right here
just put a little bit more fill that whole gap up fill that gap up just like that you fill it up
okay down here where I cleaned out my key I just fill that up and what that does is it fuses this
paper to this old wood laughs and again the old wood laughs does have or should have a 30-pound
felt behind it if it doesn't that just means it's deteriorated but we do the best we can with what
we have to work with lastly I'll point out the tops you notice we don't mess around he got a Z
flashing up there it's the sides are done when you get to the very top there's always a piece of wood
just show you this because I can alright so as you take the wood and our paper is gonna cover
their paper it's gonna go about right to here as we go to the top here now we're looking for
a key so this key up here is the one I'm gonna use my paper is gonna go into that key right
there I'm gonna tack it down and I'm gonna put another fat made of polyurethane caulking there
and that will that's how you laughs this stuff here anyway guys my name is Kirk I'm with Kirk
