howdy folks kirk and Jason here with kirk giordano
plastering, today I want to show you something new a new material in fact you know we do youtube
videos we got 850 or so with about 50 million views a lot of people ask me questions one of the
questions i got asked coincidentally about a week ago he's a kirk what's new in the plastering
industry from the last 20 or 30 years and i thought ah well there's quite a few new things but
today in particular we're going to be going over uh brick cinder block you can call it but this
is brick when you go over say retaining walls whether or not they're solid concrete whether
or not the texture none of that stuff matters as long as you use the right material i'll tell
you a material that we're going to use today and they don't even have this at my material yard
west side building supply is where i've been going for 40 years i take my truck in there i said boys
load that thing up and they come with a tractor they load a ton or two of sand they put 30 40 bags
on the truck because you guys if you watch what we do you can see our truck it's a monster truck
with 11 foot bed and it'll hold a lot of weight anyway this particular material this is
funny because this is going to be rambling guys i'm not going to show you immediately
so if you think dang i don't want to hear just skip way up forward i'm going to uh
explain about this bag we've done about well we do a lot of work where other people
do the lath and then i get to the jobs and we're ready to go and they say kirk would you
use our material and i say you know i'm not familiar with that material we're familiar with
i'm familiar with um say hydraulic cement such as eisenhower rapid set there's no um portland
cement in that it's hydraulic cement you're not supposed to mix portland with that i'm
familiar with that i'm familiar with the 690 bmi with fiberglass in it and lime it has a lot of
lime i'm very familiar with that i'm familiar with lehigh's premium plastic cement i use that often
because i like it this stuff here we've gone to enough jobs and we've loaded up about 20 bags and
i said guys i can't use it a buddy of mine had a job i said well i'll tell you what man and he had
some bags i said i'll i'll apply it because i've been hearing good things about it so i want to
tell you what's what i know about it and i just i used it a few times and i thought damn
that's some good stuff anyway it's called um uh what are we calling this stuff green core green
core usa now they say it's green and there's a lot of reasons why it's green uh meaning it's good for
the environment but anyway this 80 95 that does not mean the sand grit the sand grits for a lot
of our materials the finishes are 20 30 30 30 and 16 20. that doesn't mean the sand grain what that
means is this 80 pound bag will put out as much as a 95 pound bag in our trade for the last 50 years
all the bags come 94 pounds so they're kind of trying to say that for this 80 pound bag will give
you as much as a 95 pound bag and there's a reason why and it's true okay now this stuff here it sets
just like say an eisen wall a rapid set you can do back to back coat and you can go over a wood
house say it's got lath on it metal lath and it's uh two ply paper and it's going over a substrate
of wood you can go over that two coats same day it's a very fine sand in this it says fine
because the sand is fine what i like about this it's portland cement with slag you say what the
heck is slag well slag is a terminology of um iron you you heat the iron up and the excess is
called slag and they use that slag for say roads dams and what it means is it's
permeable it's kind of like lime except it's different a little bit different i personally
like it i'll tell you some more stuff now because i'm starting to ramble but here's something
when we're working inside i want a mud that is like whipping cream what kind of muds are like
whipping cream guys struck the light you mix that and you can put it two three inches thick and
it's very very light it's called structure light now all the rest of the interior plasters like
the veneers or any of the i mean you take veneer you take imperial those are like butter those are
cool you take tape and mud those are cool that's like butter you take the hot muds like usg or fast
patch when you mix those and it comes in 20 40 60 90 hour and a half mud you mix that it's like
butter those are okay but that structure light is beautiful when you apply it this i found is
the same similar it's beautiful to apply because it's very fluffy and you can go thick i'm going
to give you an example here we just did these this tile here and yeah this took us three hours
to do jay and i and the towel okay picture this look how thick this is the guy said guys can you
include these towels i said man you're attacking on an extra hour and a half two three hours okay
this comes out about three quarters of an inch we had to put a bonding agent on it this is weld
crete on concrete it's funny people say why do they call it sacred why they call it weld crete
why do they call it um quick crete the the last name crete is like concrete so that's telling
people this is a product you use with concrete anyway so the weld creed is this blue stuff is
that's that's what's in that five gallon barrel right there weld crete because they're trying to
get the terminology like concrete meaning the two go hand in hand one's uh this is concrete with
cement over it and then the bonding agent anyway getting back to the tile this tile when we put
sikaflex on it stick it on there and then embed it with mortar this is what we did right here and
this is still green meaning uh we just did this how thick is this and how good is this material
the material's about an inch thick meaning that's pretty thick kirk you're the best very
thick we had to put these on butter each one then cover them all up then clean these and
then come back with a rag and butter that up and now i'm going to take a steel trowel and go
over this five six times and the steel trowel has got to be wet otherwise this is gonna drag
yeah i'm playing around there only because i can getting back to this material i want to show you
i'll tell you some other thing about it because i'm about to spread it so i'm going to spread it
and it's good if i'm going to introduce a material which our yard doesn't even sell and i had to go
all the way to home depot to pick it up and load these bags individually like i haven't done that
in about 15 20 years that's how good i think this product is and no they don't subsidize me or pay
me or anything i'm just i like the material i used it only four times and i thought dang this stuff
kicks butt anyway that's a slag cement i'll tell you just a couple little things about it since
i'm going to be using it i've printed these this morning the iron used to produce steel and the
malted slag converted to cement-like material by rapidly cooling it with water this rapidly cooling
called quenching creates a glassy granules which is then ground into a fine powder known
as slag cement slag cement is what this is this is half slag and half portland so that
makes for an exterior whipping type cream and again i've used every cement on
the planet guys at least 50 times each this one is a new one to me but i really like it
because it's fluffy and you can play with it it's light i'll tell you something else it had i mean
i don't want to read all this stuff to you but i printed it this morning and i was reading that
jay was driving to work today and i was reading it i said hey jay check this out it says slag cement
requires literally nearly 90 percent less energy to produce than portland cement according to
the slag cement association yeah there's a slag association uh substituting 50 slag cement for
portland cement reduces greenhouse gas emissions by more than 40 and lowers the embodied energy
of concrete by more than 30 percent do you guys know what that means me neither i'm an applicator
not a scientist but i'm reading through all this stuff and i i got an idea what that means it means
it's beneficial and i don't want to bore you guys anymore with all that stuff because that was quite
a bit let me show you how well this stuff spreads and yeah we just did all the hard stuff that took
us three hours because jay had to hold the tiles and i i mutted them then we both had this what
we're trying to do is a hard steel trial finish can you do a hard steel trial finish with any
cement no you cannot guys if you could i would know how to do it because i'm an expert in this
stuff uh i'll show you how easy this stuff spreads now it's just jay and i here today my brother
lou he's on holiday okay guys i'm gonna show you how how easy this stuff spreads because we can
generally i like to use these green scoops right here and i'll take it out of the bucket myself if
i were to put a board in sand i'd be way up here you take your scoop wet it first guys
then our mud is here and my my little uh my drain right here we've had to pressure wash
all this i forget to tell you guys all these little details we pressure washed this and
of course within a minute this filled up so these don't work it took us forever
another hour and a half just to clean up the swimming pool that was created
so we got to tell the people hey guys that's your your stuff is broke we didn't
break it we haven't even started yet and we tried fixing it for about an hour anyway that's
a whole nother story but i'm well aware of this oh i don't want to put my foot in it ah okay here
we go now look at this stuff it's usual cement you can't kind of do that with it's uh this is the
equivalent obstructor light so it's very fluffy okay going over this that's a thick that's a
thick finish right here this is a heavy skip trial finish it's called a 16 20 skip trial finish that
means it's a heavy aggregate now to go over this It takes a little bit of practice
all right now. So now watch this unless you're familiar with uh plastering,
you say I don't see any difference. Hey jay, can you pass me my congo trowel? Please,
I got it. It's right here in the bucket; I'm using that 16. Gotta have
my 20. okay, I've got my 20. Normally with other cement, all I can use is that
16 because this is not so heavy. It's got that slag in it, and slag is very lightweight, okay so
what we're doing guys, is we're putting another coat on here, and he wants a steel trowel finish,
so a steel trout finish with sand and cement guys I've been doing stucco a lot of
years and I'll tell you one thing with stucco I mean exterior cement
plaster stucco render the same thing with stucco you could only steal trowels
so smoothly because it's got sand in it it's not like an interior tape and mud
which has no sand so when you're working with materials that have sand in it you've got
to know what you can do and what you can't do. Now here's what I'll do, guys. I'm
showing you how effective this is, and it's sold at home depot. All our weekend warriors
watch what we do that's the only place they go because often people call me to say kirk, I can't
find this with that material, and I'll say, dude, that's because it's sold at the plastering yards
get on your computer and google plastering yards near me that's only where place you could find
some of the materials we use however this one I believe is sold not only at home depot but
at least two okay now notice what I'm doing. He wants a steel trowel finish, and I tell
him too how about a float finish, meaning we put it on and then we'll float it for you. So
this is well. I prefer a steel chop finish. I'll say do you know that is we'd have to skim the wall
come back and do two more coats of Santa Barbara, and I explained it to him. He says, well uh, you
know what, you're pricing it out of my range. Maybe that's a sand finish you're talking about I
can live with. I thought about this material, and I said, you know what, man, I'll go ahead we'll
do it, uh well actually jail do it because this is jay's job we'll do it. We'll use uh the green
core, and of course, he says what's that, and I thought you guys just heard me explain I thought
never mind man we'll just do it uh so here's what we're doing, so we're taking the trial. We're
coming down now, notice that's pretty smooth already now this is without me coming back see
what I'll do is I'll let this set a little bit. Okay, that buck is done. I'm
going to the next bucket. and no doubt um jay's going to have to mix up some more,
and while he's mixing up some more, I'm gonna take it just to the corner um, that's all we're gonna do on film, take it right
to that corner, but if you guys are doing a house and you say you're not that good you're an
apprentice or a homeowner, and your skills lie elsewhere you just go to home depot and get
this material because talk about user-friendly it was the most user-friendly so far of all the
materials so to answer that one guy's question last night I said well I've got a video where I've
got a job we're going to be doing is jay's job uh we weren't planning on doing a video,
but we'll do we'll video it just to show you the material you see it's getting hard
this stuff is it gets hard uh it's uh it's on a set time guys so generally what
you do is you mix up only what you could use and say for us uh we know what we could use
and whether or not we're mixing with a mixer or in buckets like what we're doing i tell you
we're in san francisco we're up like 30 40 steps to do this and we're using a milwaukee drill
that's battery operated so you notice how hard it's getting already this is what i'm talking
about there's no way i could have did that with jay's help even unless we had a material that is friendly with us meaning you know we
got skill but you don't want to burn out muscle and if you guys have a hard time thinking
man i did that my arm is killing me at the end of the day you try this stuff um it works
well so i'm done jay we're gonna need another another two buckets when he gets back what i'll
probably do with the last bit of mud is finish this top and go to the corner i'm gonna
show you how easy it is to finish this or well we make it look easy because we have a lot
of time in but you guys will too once you try this material you'll say wow that stuff spreads
easy because it's like whipping cream even when it's getting hard like this this has a set time
of about same as bit by same as rapid said same as eyes and wall about 40 minutes so that's
about what you want guys you don't want to be spending all day waiting for it to set you want
it to you dictate the sec time you dictate it not the wall anyhow mud jay just mixed me up some
new stuff and because we're on a time limit this right here is gonna set a little slower
than the rest of this but the time limit i'm talking about is we are far from home we are far
from home and we didn't anticipate putting that the tile in right there which added close
to two hours for our day and i want to beat the daylight, I mean, I don't want to have to come
back tomorrow, so I'm going to hustle right here and just uh finish off this one wall and
show you guys a couple other little things because nothing's worse than where we are,
uh the street is so narrow it was tough to get here then we got yelled at by about five
different people because they're building four buildings on this one narrow street is so
narrow if I took you to it you'd say wow how did you get that big truck there well it wasn't
easy anyway um I'm gonna show you just a couple things right now and note yeah this is different
set time than what we just did, but not much only about uh say 15 minutes difference
okay now what I'm gonna do is get my top It doesn't always work out, guys, but that's close enough. So you get the
top like so, and you come back here. and get it now You just go over it a couple
times, and it will line up that cap will line up. It takes a little
bit of practice but it all lines up. You have something stubborn like that
says, no man, I don't want to cooperate. Make it cooperate okay, so now this is going
to sit for 15 minutes. I'm going to take the trial and come down on it like that, and
that'll pretty much finish it because again, we're uh, we don't care about traffic. However, we
are far from home. We care about not finishing and coming back the next day because of that nonsense
right there okay, let me show you just one last thing, guys. You can envision the results because
we've already got the results done all right now. This is a new mud, so this got to be
taken about a half-hour. This is almost set, so we're going to just feather
this into the existing. feather into the existing Nothing to it if you know how to
do it. Hey, that rhymes, okay. one more my hat's off to green core
because i like this material of course i got to tell my material yard
dude you guys better start selling this stuff otherwise i'll have to find a mature yard that
does because last thing i want to do is load my own material i prefer to go to material yards
and have them loaded up and we get our sand i guess i didn't say which is you know you try to
cover all the bases of a material then people ask me well what about this what about that so this we
can add sand to it guys this has got its own sand in it so all you do is you mix you mix
bags there is no adding sand to this uh it's it's pretty user friendly i mean if
you're at say home depot and you're looking for a good material that's about as good as you're
gonna get if you want something that's uh at home depot also and you're in a hurry and you
want thicker sand you can get rapid set stucco rapid set i've done enough videos with rapid set
and explained it uh if you guys have questions too by the way if you have questions if you're on our
site all you gotta do is everything man how do you mix that stuff you put how to mix rapid scent
how to mix um green core how to apply green core how to mix it won't be done yet
because not on our channel because this is our first time actually uh using it
for somebody else we've done it a few times but we haven't videoed anything yet with this
particular product anyway there it is guys and that's over extremely heavy skip trial finish
that brickwork over here it doesn't matter if it's a chimney whether or not it's a brick
wall if you got loose bricks they're all coming out just go over it you don't have to tuck each
individual brick put this over it or put rapid set or any of the other products but i specifically
like this stuff because it is airy and fluffy and even a strong arm like mine gets tired
every once in a while so this is lighter all right guys we'll show you the conclusion
just because we can and we still have a half hour daylight left anyway this is a two coat base
coats finish and most people say you cannot do a steel trowel base coat finish can't be done
but jason loves doing them i don't particularly care i tell people hey look we'll do a base coat
we'll come back and do two other santa barbara or finish coats with 30 30 sand that's like silica
or fine talcum powder anyway with uh with a two coat system with this particular material you're
able to achieve this of course my arm feels like rubber right now and that takes a lot to make my
arm feel like that because i'm so used to this jay's only gripe was he says oh i put the
tile too low i said man i can't notice that kind of stuff just by eyeballing these i
think it's absolute perfection and here's uh the seat we got rid of the so-called bird
baths this had a huge it would collect about a gallon of water we just got that out anyway guys
it just shows what you can do with two coats but you better have a lot of material knowledge
in with the material knowledge is so much longer to learn than the actual plastering anyway
this is jason's favorite he loves doing these hard steel trial finishes my name is kirk
jason on the camera and he spread half of this we thank you guys for watching and as
usual we'll see you guys on the next one hi folks jason here and i'm here to tell you
something you probably already know that like most content creators on youtube my dad and i
are members of the amazon affiliates program what does that mean that means that we can show
and link you to some of the most commonly used tools in the plastering trade on amazon
like our hawks and trowels scoops floats and some of the other things our battery
operated tools for breakout and cutting etc now if you buy those tools from those links we
earn a small percentage of that that allows us to keep making these videos and keep putting
out quality content for you folks to enjoy once again folks we thank you for watching
and i really enjoy all your comments if you guys like this video please click the

keep making these videos for you my name is kirk and jay we thank you for watching and from the
entire giordano family we'll see on the next one.
