Hello folks, Kirk and family here with Kirk Giordano plastering, I'll answer a question I get
asked quite often. Folks will see our videos and they'll say geez, I think this fella here knows
what he's doing, and after close to more than 30 years. I do know what I'm doing, as far as flashing
and counter-flashing and what you can do what the city says it's okay what the city says, "no
guys," that's not gonna fly. You take for example existing from porch or rear porch and I do this
all the time. There are about 20 different ways to do this, but which way is the best? And which way
will the city say will say, okay guys, that's cool that'll work said we'll sign you off on an inspection you take
the existing porch here that's a brand new shear wall. The whole house has been redone so how
do you flash properly where the concrete meets the plywood? I'll show you which way we're gonna
use, and by the way, there's a lot of different ways to do this one of the best ways is about the way
I'm gonna do it right now. Okay, we're gonna take a staple gun our corner right here we're gonna
flash this corner we're gonna get it watertight. and a lot of times guys these don't want to fit
That's okay, we just fish them in there. For sake of explanation you grab my little hatchet
here. The funny thing is, the homeowner here I've done about 10 different jobs for him, and he
brought this out today he says, Kirk what kind of flashing are you gonna use I said well I'm
gonna use a metal flashing, because I can't use caulking! While we're at this guy, I'm gonna
show you what papers you can't use and which ones you can, so he says well I hear this flashing
here is pretty good, and I said, yeah "how about that?" Most of the flashings cannot be exposed or
the caulkings and I said I showed him this box right here, I said I beat you to the punch, man.
So he's smiled because I just opened that box I said I was I bought this box here because I used
different caulking for different things, I said I'm going to use the exact same thing, this Moistop
here it's butyl-based, what does butyl base mean? it's the same mineral that they put in windshields
a glue-ish type of thing. And it is allowed to be exposed, so we take caulking and what I do guys
is I'll poke it a whole bunch of times to expose a big hole, now what I'm gonna do is back here I
already did this one piece of flashing so what we want to do is fill this up we fill up the gap
a lot of inspectors don't want to see caulking but we could only fish that metal down so far, I
mean it's just it's going to hit a nail. It's gonna hit something, It's gonna hit a nail a staple, and or
the concrete is too tight against the house now what I did is, I had the luxury earlier is i shimmed
it. What does that mean? Because it was so tight I took a couple of my hatchets and I pounded them
in here for 10 minutes, and what that did is it moved the shear wall back, we'll see just how far
back in a minute. All right say for example now you don't want a whole bunch of little
flashings and I am going to counter the flashing with a drip screen so what I'll do first of all
is I'll put one piece in here and the idea guys is to try to eliminate a whole bunch of little
pieces. If you can, you can't always do it. Okay, now that one's in there, nothing is showing, why?
and guys if you're gonna use a gun, wear glasses, a staple can shoot out. Okay, now for example this
is a 17 gauge, this is 17 gauge will my gun go through two 17 gauges? Usually not, so we have the
1 there, and then this flashing here, for the sake of code, they usually wanted on new construction.
2 inches, but we don't have that luxury here this is existing we want it to be about a 1/2
inch because it's not all that pretty to look at that metal, in there, so there's a half-inch. I'm
not certain if this gun will go through both of these. In fact, sometimes it does sometimes
it doesn't. but I got a piece of wood there I got nails for that anyway I'm gonna go back up
top here and show you how we get that a little bit. Baby, give me a hand right here, sweetie,
Okay, now this piece earlier I was saying I had a bunch of shims in here and that was to separate
the plywood from the concrete, we did the best we could and see we can stick this guy in here
too. Perfecto-Mundo. Okay, we want to get this in and usually, It'll teater, you put it on one side
that teeters the other side and with those shims it works out real well, "perfect baby," pass
me the gun, please. Okay, now that we got this piece in here thank you three I'm gonna staple this off,
here's a good reason, there's a reason that I like to use a smaller piece here knowing that
we're going to put counter it with a weep screed this is a weep or a drip screed they both mean the
same thing now this guy here as I put it on here I only want I'd say about a half-inch monk most a
half inch is fine actually the homeowner wanted me to drop it down like this I said, inspectors
not gonna let me get away with that he's gonna flag it and I have to come back and redo it so
we always got to have some kind of a gap, guys, and what I'll do is I'll just use my fingers
for example. Okay so that's where my fingers say it is and that would be about a half-inch, half
inch is acceptable for existing work. Now we have an expansion joint there. And it's the same metal you
got metal here, see all these flashings right here, I get asked a lot of people say can you
use a Dupont straight flash, here it's butyl-based? No, can you use the membranes of the peeling sticks? No, can you use the
papers as ten different papers? No, why because they're gonna be exposed to the weather and elements for
what a hundred years, so let's get back over here now, and do one thing, when you have two flashings
countering each other, the biggest drag is, how to do you, how do you use a nail or a staple to do here.
Okay, a staple won't go through two seventeen gauge metals, so what I'll do is I'll look for
a stud because it won't it won't flex as much. But I don't see a stud so I'm gonna put it right here
at the bottom, and that's how you lose a thumbnail, by doing that if you miss and lastly we got one
more piece going here and this one is going to be stapled on or nailed on just like this, and
now the paper goes over this and that's the way you do existing concrete porches, front porches
back porches that are the way to do it this moist stop here is a pretty good product, I thought I'd
show it, because the homeowner was, he brought it to my attention this morning and last thing Jay says
that's the way to buy a house right there, he, says "Thanks, mom and dad," because the mother and father
helped him to buy the house. Anyhow my name is Kirk, I'm with Kirk giordano plastering, hope
this explains just a little bit about how to flash existing porches or back porches when you tear all
the stucco or siding off of a house. Because we do this often. Thank you for watching we'll
see you guys on the next one.
