Hello folks, kirk, and Jayson are here with kirk giordano plastering. Today
was n going to repair this deteriorating concrete wall. I guess in order n to repair a concrete wall that's deteriorating,
you've got to know a little bit about why the concrete deteriorates the wall. There are
many reasons why concrete material the carbon dioxide in the air can deteriorate concrete,
rebar too close to the surface can get wet because it's porous and corrodes then helps deteriorate concrete.
the fluoride in the water
can deteriorate like this actually is a little bit more than the three I've
mentioned of course I'm not here to explain why concrete deteriorates. I've just given you an
idea, if you want to really know why, Google it, they can answer it a hundred times
I looked at this right here and I figured just from looking at it it was about 110 years old
and I also can see by looking at it closely that fellas about 30 years ago did stucco they did
just what we're going to do, but some of it came off, so I advised the fella who only put pressure
washer with 3000 psi which he did they did a really nice job Josh Jason will show it to you
soon they did a great job and they took off a lot of it however I came in I tapped it with a hammer,
and there's still a lot that's gotta come off, so the fella that owns this says, I don't want to destroy the integrity of it or rebuild it
so I'm going to tap off a little bit more
I'll show you how we repair it, also too, concrete it very similar to stucco they are both made with Portland
cement aggregate water, stucco we add sand as the aggregate, in concrete its rocks, can be quarter-inch half-inch that's that's the only difference.
anyhow but we're prepared to do today is pound off or knock-off gently any of this stuff and then we're going to pressure wash the loose stuff that
I have to get all this out otherwise our new work blown in here so we're going to pound off some of
the loose stuff pressure wash that to remove all this and we're going to hit it with weld creat
I'm probably going to come back tomorrow and do the actual cement fix to this and I'll freehand
everything we're going to beat up some of these corners and try to salvage everything that we can
we're gonna get set up guys and working pretty high up on it wall here so I'll have a harness
with my scared self, looking down here it's. big drop, Anyhow when we get to that stage we'll show it to you. we're going to get
to the fun stage now, we try to remove the loose stuff and here's where it takes a
little bit of practice in order to get the loose stuff you could go by sound basic.
this right here that's lose this iffie that's solid so it
is loose like this best thing is to take a claw and pull it out of here, this does take a long time
well it says again I don't want to remove the whole thing we don't either,
but we have to reduce them tell us who did the last work I give them out 30 years in class, so we
want to do as well or not better like areas like this solid, solid, solid I can see a buckle here
Move back, and that's how we determine this area inside here,
solid moose. You can hear the difference. Hopefully, you folks can hear the difference,
so anyway, after we remove all this now, I'm going to crush your wash just once more. He
did a great job with 3000 psi, but I want to hit on let's get all this loose stuff off,
then we apply the bonding agent, which I'm gonna double up.
All right, guys, we got that nasty worked out of all the breakout. This one color is the absolute
worst I'm talking about earlier with an aggregate like a dinosaur. These rocks in this concrete,
right here would point out that rebar close to the surface corrode a deteriorating business.
This is right on the surface, we had a few other things here. Still, its nothing that we can't handle , anyhow Jason
viola anyhow. I am going to clean up this mess, then you will pressure wash it to get all the
dust off of this; unfortunately, come on top of this roof here, we can just relax and reach
over. That's how I was able to get down. I'm not on the ladder. Just reach it down comfortably.
that way, we get good here fun we've got super-rich mud plus we have accelerators
I will stop down six inches in some spots and I am going to complete
I could take it to throw it in there like that I'll be doing the whole all the heavy
6-inches patches just like this I wanted to set immediately now where I can keep moving
we're gonna give the hot Sun, so we're hustling now
but actually, the ability to get in this corner okay I get it I generally put some
on here this is a really hot mug, so I got to get rid of it in five minutes,
so I'm going to put some bulk here Oh a little bulk out of time guys a little bit take it
sure how I get my take it here working a hot sun too,
so it makes a difference for when this sets alright okay for Darby now be doing
a lot of leather do this I'll put it about right here squeeze it down the line these
corners up I'll take this guy here pull it straight up just like that.
Anybody order a pizza?
Give that guy a tip. We're going to take lunch, and afterward, we'll come back and show you the
completion of this alright guys now that I got this one portion here sponge fluid everything a
lot of water now to give me the stucco finish that they originally have anyhow I hope you
learned something about deteriorated concrete and how to repair my name's Kirk I am with
Kirk giordano plastering, we thank you for watching and as usual guys, we'll see on the next one.
