Hi guys Kirk here with kirk giordano plastering, I got a question for you guys how many of you guys
know what the name of this sheathing? See this new sheeting right here? This is new plywood obviously
the new sheathing here, but do you know what this is that's called many things like Wynette
sheathing, it's called Berkeley lath sheathing, it's called old redwood or cedar resin-treated
sheathing, how about just for the sake of this video we call it old Lath and plaster sheathing?
What it is, is, it was in the 1900s to about 1920 roughly, don't quote me on that.
And you put the paper on the studs then you put this sheathing on top to stabilize everything. it's kind of like well,
it stabilizes the whole house, it reinforces it this again is new plywood, and they also have the
OSB plywood, the idea is to stabilize the house with on the studs anyway, how do you tie in to
this stuff here? I get asked this all the time by homeowners, so I think the most common term
is Berkley sheathing lath, from the 1900s to 1920 so we'll just call it that. I was looking at the
foundation now this is a tough foundation because it follows the contours, the grade it goes in and
out, in and out, now I looked at this I told the homeowner, I said this is, Alameda structural
huh, he said, how did you know that? I know Alameda structural, they go way above beyond codes.
they got flashing here goes all the way down it covers the mud, so before they put this concrete
counter flash it then they counter flashed it with L flashing here, with a slant so that the
water runs off. Tom Carroll foundations is also as good as these guys thought I'd throw him a
bone as he's my buddy. How do we, how would you guys drip this out? well I'll give you a few tips guys
because this is a tough drip situation, what does the drip screed do? This is a drip screed it's a weep
or a drip screed, it means the exact same thing. We have to protect the mudsil,l this sill plate
has to be protected. so we are going to protect it. I'll show you right here we're flush right
here we don't need a weep screed, because we were to put a weep screed, now look at all this metal
what's the purpose? We have three pieces of metal the water technically supposed to go through the
stucco, go and drip out harmlessly through these weep holes or drip holes. But it's not necessary
and by the way guys, the stucco we use is it's not very porous, some would say waterproof in
fact, I've watched about 20 videos and they all say if done properly stucco's waterproof. I look
at it as it's water-resistant, so do the best you can with you paper and wire it. That way you're on
the ball and you're sure. Okay, just for the sake of showing you guys how to do this. All right, number
one we got here's the Berkeley lath, Or lath, and we have the new plywood. Okay, we're going to
cut a piece, this piece here should pass this by an inch technically and it should pass the other
direction. We want to protect the mud sill, so we're going to drop the bottom of this at least
an inch, so just for the sake of say, getting it on there, we take a torpedo level or what other
level you got, and let's make this guy straight. Okay, there we go we're straight and, boom, there it is.
Now what I did earlier is, I cut a little piece here, and I cut a 45 so that it could match
up, and this one was a little bit short, so we're, no big deal, just cut another piece guys, that's what I
did because that's what I want, I wanted to land on top of it. if it can show, now I'm gonna put a
staple in here. Okay, that's simple stuff, guide let me go over here and I'll show you what what
is more difficult. And of course, we've got to put paper in here, you got to go through a ton of caulking
guys. So we'll get to that here's the complicated part of a little bit more difficult part for
you homeowners, because we even have a hard time with it sometimes. Now notice these guys.
The only cardinal sin I've seen them do is they stapled this down. I just took a screwdriver I loosened
it because I want to go underneath this. Alright say for example, now what we want is because we
have this and get out my own way, because we have this vertical we've got to protect this mudsill.
This sill plate mud sill has got to be protected so what I'll do generally is I'll figure out where
I want to go with this, and I figure about well kind of right there, and what I do is I'll put
one staple dead center, that's where I want it now I'm gonna take torpedo, put it on there get
it level. Okay, we're a level here, and put a staple in it now, I want to bend this down, so I cut this
screed here, and I'll cut it about right here, now guess what guys it'll bend, blam, Okay so now that's
bent, notice it's bent and it's stacked where this is intact, here so the next thing
I want to do is put a weep-screed onto that and we get the next screed on here, and we just keep
doing that we put this one on we've come down here we put this one on we put that one on but
I'm gonna jump ahead you guys, don't really want to see them let me do that stuff there let's jump
ahead to the next stage and then I'll show you some other things paper how do we do the paper
once we got it all drip creeded out, that drip-screed gonna take me an hour guys you really don't
want to see that but I'll show you what we do now notice there's no plaster, stucco in these
keys, why? Because we took a screwdriver and got it out, plus the vibration of breaking it out has got
it out, well also notice this, this fellow's got a Z flashing right here they're protecting their
own plywood with a Z flashing then this Z flashing goes in back of this old lath and plaster so what
we're gonna do and this is really time-consuming. so I'll just show you one piece of what we try to do
is. We go into the groove alright so we're going to go in this groove right here and go back and forth
let's just get into that groove and once we're in that groove hold it down the best you can and
put a staple in it put in the groove you might say well how does that waterproof it? Technically there
is my heavy, this is two-ply paper behind this old lath and plaster it is like a thirty-pound paper I
know it because I could see it in different places now we smooth this down right here we'll take our
knife utility knife hold it down and cut it right there it doesn't have to be perfect this is melt
two layers of metal no but then once we're done here we're gonna wire over this but here is the
key this key right here has got to be filled with a polyurethane caulking now this is the
caulking I prefer we're gonna see if I can go on the other side because it's the whole car to get a
whole length on the other side so it's easier to explain rather than me take 20 minutes or paper
this whole thing so we're gonna jump over there and I'll show you that part all right guys give
me a couple more tips this is probably the best tip I can give you as far as there's old lab and
plaster you take caulking okay good caulking when it's cold you're gonna want to swarm it's a drag
to get out of the tube now every caulking gun got this where you puncture the seal inside this is
useless for any polyurethane caulking especially this one take a screwdriver and you cut a big hole
he this you don't want to skimp it's not like carpentry stuff you you poke this you poke it
5-10 times you get that so this stuff can really squirt out why because I've broken about at least
30 of these guns right here with this hulk like grip, I mean you grip it and it won't come out
especially if it's cold right now we're in the Sun so it's coming out. but this is the key to
putting a lot of waterproofing in here we got a lot of things going on here guys in fact we're
just in the hot Sun over there we couldn't do it so we're retrying it on this side to show
you how important this caulking is I usually bid an extra hundred bucks on something like
this because I will go through a case of this 24 tubes I've already just on this little area here
I've gone through about well these six tubes here's the key to this old lath-and-plaster
you take this polyurethane caulking and you get it in there you squeeze it. I do not advise
any of those cheap interior caulking's that they say 35 years for insides, you don't want that guys.
This stuff here is waterproof it stretches it flexes you could take three drops of this and
put it on two bricks and those bricks will remain forever, bond like a loving relationship. they'll
just stay there forever, Okay, now we'll take this one here and we'll go on this vertical and this is
how you waterproof this stuff if you don't if you don't use this good caulking or any polyurethane
caulking you will be screwed guys and make sure you open that tip up with a screwdriver forget
about this little pin it's useless then what you do is you'll take some paper and get it in there
guys because if you push it in there tight it's gonna hold that paper in there sometimes when
you're when you're doing this stuff it'll have the tendency to want to come out it'll pop right
out so now it's sealed this stuff I mean it is a sealing this is a construction sealant meaning it
seals everything, we seal all our penetrations and everything that's the biggest tip I can give you
as far as this now we're gonna wire the rest of it and we'll show you the completion when
we're done and by the way I was showing you these screens earlier how you doing you can see them now.
Okay guys, brief summary of what we have done today the back the sides we'll just go ahead and show it
to you real quick tying this stuff in and yes we used a lot of caulking on this particular job your
best friend is come on over here for a sec Carl is a torpedo level with a magnet because all of
these foundations you put one staple and then you bend it flex it around your next bestest buddy is
paper just a piece of paper wrap it about four times and when you caulk this take it go with
your hand tight because another worse and get miss Sikaflex all over you pain in the arse
okay I don't know he is about 20 tubes something like that but for the fella who keeps calling me
saying look Kirk stuck is waterproof so what you want to make certain anyway guy caulking is cheap
compared to a callback was like 150 bucks for a box it's cheap compared to one callback you call
kever eating you caulk here you caulk around your vent you caulk around your pipes and we're using
a construction sealing you caulk your joints you here caulk your paper joints all the way
around pop your corners on oh man we got a lot of you guys here and all kind of people you're still
picking that up Lou we come around here we talk all the tops we talk anyplace that is tied into
there's busy cleaning up anyway we go around here careful now it's like a maze watch where
you're walking, Carl. Okay, yeah we had a chimney too but oh here it's more the same stuff guys
the chimney where we have that old lath and plaster we use a lot of caulking, caulking caulk the crap
out of it guys, caulk the mess out of it because you don't want it to leak and personally my, my
thoughts on this old lath and plaster I've seen so many houses with at least 50 houses and if
you paint your house every 10 years this stuff will last you forever. I mean I'm talking a thousand
years but if you neglect your house for say 25 years then the weather starts beating it up or
you have things that are leaking in your fascia boards, your wood is rotten that's how the stuff
starts to go, but this Berkeley lath or just old lath and plaster. That stuff will last forever as
long as you maintain it, sort of like your body, anyway my name is Kirk, Carl on the camera and of course we
got Lou over there whining about stuff as usual. we thank you for watching and we'll see you guys
