Hello everyone, Kirk to Jay here with Kirk Giordano plastering.
today I want to answer a question or actually quite a few I wrote them down but just through
the list of where there's too many things to read the question is do you need paper see right I'll
show you guys something and a lot of folks always ask me about this I'm gonna lift up this to plight
this is two layers of paper now we have plywood then we have concrete here and the question is
one a very lot is do you need paper to cover concrete if you're going to stucco it no in fact
you couldn't do paper over concrete cinder block brick or any other cement Isha's substrate if you
tried because here's the reason why no paper is necessary can you use some peeling sticks
absolutely you can use a peel and stick peel and stick won't adhere to concrete unless that
concrete is dust free very very clean anyway I'll show you why you can't use paper guys okay this
magnet right here now this magnet I stick it into my little jar of concrete screws and you see that
okay now the magnet is to put concrete nails into cinder block concrete brick rock stone you name it
what we do is that magnet right here holds holds the half-inch a concrete screw and you can't use
a hammer guys I mean you might think oh man I'm gonna use a hammer this won't work guys you got
to have us a little sludge and basically this is made like this so you don't lose a fingernail how
many finger nails have I lost quite a few okay see what you do is you put this like so tap it
and then after you tap it and get it started pull it off and one or two hits only you keep hitting
it it'll just destroy it so by the time you do this over paper that paper is gone it creates
a huge hole so I'll tell you this is more of a an explanation video on you folks who are call
saying how do we apply stucco cement plaster same thing over concrete walls cinderblock or anything
that's say cement tshis like rock stone and have I done this a lot of times let's just say I've got
close to 40 years in this one trade and yeah we did a parking structure where it took 30 tons of
sand that's like 200 bags of stucco over concrete it was a parking structure and anyway we where do
we do the stucco this way I mean what we do if if your concrete is not perfectly clean if it's
perfectly clean say you can just missed it just sort of wet it if it's dripping wet you can't
put the stucco on it because the stucco won't adhere because it's dripping wet so what you
do is you wet you wet the concrete like say for example if I'm doing a whole house it's
all concrete I'm gonna wet it the day before and then I'm gonna wet it in the morning cuz we don't
want the water dripping because the stucco won't adhere if it's too dry we can't get a mechanical
bond what's best a mechanical bond naturally wet stucco too wet concrete that's done already like
this that's better if you put wire sometimes the wire affects adhering forever if you're going to
do wire though see this this blue stuff here this is well decree weld crete is a bonding agent it
kills the suction sometimes on concrete but what it does is it allows cement Tisha's finishes to
stick over say block concrete cinder block and all the rest of those things right now what I
we're doing something here that's kind of odd now we have plywood and it blends into the concrete so
what I've done is they have the this peeling stick here and so what we do is as long as we're past
this wood we're good so I'm I'm about six inches path so I put this paper on it now that's good
I couldn't go ahead and stucco this and of course a lot of people's believe it or not they say why
do you need the wire well it's just no wire the stucco can adhere to nothing you can't put stucco
on paper and expect it to adhere to just fall right off here's what I did I pre-cut a little
piece and two guys a while I'm on this subject it's covered trying to cover a lot of bases might
confuse the majority of folks but what kind of wired can you use people say this eighteen gauge
and seventeen is not what they use in other parts of the country well that's what they use here in
California and it's my opinion the best we've got a lot of different kinds of wire this is for
soffits it's called rib lath and they also have another wire for soffits for ceilings it's called
three point four or diamond mesh both of them are good and I've heard people say well the diamond
mesh rusts it'll rust if you take the stucco and you keep stucco and over and over you remove the
galvanized finish on either anyway that's that's why it'll sometimes rust but it's galvanized for
a reason and so it doesn't rust what I'm gonna do is this is uh I've got all if you did you
name the wire I got it on my truck but for the sake of explaining different things about wire
stucco nettings and what metals you can use this is rib lath designed for feelings that have studs
every two feet that three-point-four is designed for ceilings every 16 inches so it sags more okay
why am i using this because because I can it's on my truck and I don't have to use a lot of concrete
nails so basically I'm gonna to do this in here alright so now I'm tied in stuck wire to wire it's
tied in guys now I'm gonna put a couple staples alright now here I am bending over to prove a
point guys that it really doesn't matter if you cut it off or if you just put it in there in
fact I was on a job site a month ago and we were opening the wall for exploration and somebody use
chain-link fence it was a chain link backs and uh notice at all Wow they really ruin this I said not
really a chain-link fence will work but for the sake of showing you what what I'm talking about
almost all wires can work guys a stucco netting is great if you get the the stucco nettie and
say that is like we call it chicken wire why do we call some stucco netting chicken wire because
chicken coops are 20 gauge wire it's also used for tile it's a very fine wire this stuff here
this is made for soffit ceilings and can it work yes yes it can work perfectly I'm just getting
this right here because we don't want the stucco past the wood we want the stucco to not set out
okay so this is all concrete now we're guys I know whether the wood is here's the wood out that any
wood there's the wood okay now here do I need to concrete nails guys not really because I've
already put bonding agent there but for the sake of explanation I'm going to take this guy here
I'm going to take my I got a whole bunch of these magnets you just put your concrete screw why is
it only a half-inch have you guys ever tried to put a one-inch nail into concrete good luck you
blow the concrete out so this is just a half-inch nail and so you just put it and remember tap it a
couple times and if it goes through like that do it again you can't always get this right the first
time in fact sometimes it takes ten tries you get it here okay now that's that's tight so if
I put my cement plaster here that cement plaster is going to adhere to the concrete by weld crease
the bonding agent will make it it here did I need that bonding agent no but for the sake of
explanation I put it there because I usually like to go overboard rather than under anyway we're
going to go ahead and plaster this and I might go through those notes and find any questions
I might have missed because I was gonna answer a whole bunch of questions with one video one thing
I want to show you guys is a lot of people call me it's a cookie use the wrong trowel I've been using
these child's for well over 30 years when I first did some swimming pools look guys there's a these
are little guys these are 16 or 14 inch this is what I use it's got a flat surface here this is a
radius a radius is for swimming pools or concrete the concrete sidewall sidewalks you go ahead and
use this these are 4 inches wide or 3 inches wide the ones I prefer don't have a complete
radius they're just flat here it's just the arcs that are cut anyway I thought I'd point that out
because many people from all over say Kirk you're not a real plaster because you don't use the right
track he'd use any trial guys I could use my shoe anyway we're going to go ahead and plaster
this and but think about any other things I might have missed about concrete and how stucco adheres
I already remembered something before I started plastering caulking guys what kind of caulking do
you want to use on all of this you want to use a polyurethane which ones are polyurethane you
got sick of flex 1a you got moist stuff as long as it says polyurethane there's 50 brands of caulking
net you want to go ahead and use everything was cocked already but this is what you do after you
put your paper you just fuse that together guy this fuse it together get your caulking in there
and make sure that you got a second bead there that way it's your guaranteed no leaks even though
it's already been caught anyway guys thought I'd point that out too because there might be someone
said you is man you guys didn't caulk it or you guys didn't cover the floor I get a lot of calls
like that and they say you guys didn't cover like guys leave that stuff to us anyway as we get done
I'll explain what we did in how to achieve this to the heck of it alright guys it's an hour later
got one inch here two inches on the bottom when you're going over concrete put a half inch at a
time a half inch if you got to go six inches just go a half inch each time allow each coat to suck
up and absorb in then put your next coat yeah and of course another question we get often is Kirk
we're working it's about a hundred degrees well it's about a hundred and three right now has to
be because I'm in the hole right here every time we're in a hole that's when it gets really hot so
if you're working so you're doing a big wall guys and it's a hundred degrees these walls absorb the
heat and now if you don't keep them moist ahead of yourself say you wet the whole job down prior at
8 o'clock anymore 10 o'clock in the afternoon now 100 degree weather it's just baking that wall you
got to hit it again wet it again because that's what this video is about how to apply cement
stucco or plaster or it's all the same stuff over concrete and habited here permanently and what's
the right way the mechanical bond the mechanical bond is porous the walls porous and wet the new
stucco wet and they absorb and that's how they adhere all right guys it's Friday August 23rd
everybody knows what that means that's my birthday it's about 5 o'clock we're in the hot Sun Jay said
