hi guys Kurt and Jason here with Kirk Giordano plastering,today I want to show you guys something
about hairline cracking this is a little bit more than hairline cracking but I get a lot of calls
from folks who say gee I have hairline cracking I think I need a new foundation not necessarily
guys this is a lot worse than hairline cracking but I'll tell you guys what it's about because
you might have a similar issue and take oh my god I need a new foundation you don't alright
guys you see right here this big crack right here in this crack what's happening is the ground is
settling when they built this house I don't know 80 years ago they had tractors and the ground
tends to settle you get the rain it lifts it then it settles when drier conditions occur I'll give
you I don't want to bore the crap with you guys but I want to show you how to do this I'll give
you a quick example we did a theater in Blackhawk about 30-something years ago I was working with a
company and we gun did we sprayed it and all the stuck at one on the ground thirty years later I
got a call it's odd and they said hey can you come and tell me why this is happening and fix
it that's I said I already know why it's happening I went to part of the gun cross you know in my 20s
we sprayed it we left all the cement on the ground and as the ground settled because tractors moved
it all the dirt the stucco stuck to the wall and then there was like this much of ground that just
means guys it's typical is normal the ground settles when you have tractor work going on
and that's what's happening here that's why you got this crack here you got this buckling here
because it's locked in guys it got no expansion joint typical we've got cracks along the house all
this stuff guys is very typical and it's normal does cracking hurt the foundation like this not
necessarily it doesn't dance cracking doesn't indicate that there's a structural problem it
doesn't jack up the integrity of the building itself it's just a hairline cracking which is
normal and this is actually quite normal for a building 70 80 years old I'll show you how we
fix it guy okay the guy here had a lot of concerns and I said dude don't worry oh well we'll handle
it what if there's wood rot I said well we'll cross that bridge when we get to it there's a
lot of different things to do if there is first of all you're gonna chip this out guys where are
some glasses tiny chip you can use a hatchet you could use a handy-dandy putty knife you could use
whatever but when you do it if you're hacking away wear some glasses I don't care what kind
of glasses they're like okay we're gonna open this I don't expect to see any wood rot guys oh oh you
know baby I'm not gonna use that thank you you guys could use a tool like boss Bulldog or so you
could just do it by hand guys the the this is so little it's not kind of worth putting stuff like
that together once you get all the loose stuff off guys we're gonna get rid of the dust now how are
you gonna get rid of the dust guys get rid of the dust by while you're brushing and then house a new
stucco going to adhere well once all the dust is gone then you take a bonding agent there are many
types of bonding agent I like this weld Crete I've been using it forever like 30 years or more so the
weld Crete actually will stick to the foundation and then when I put new plaster on it it'll
hold it forever how long will this fix last this temporary fix will last perhaps five years perhaps
15 perhaps two weeks you never know because we are getting saturated with rain it's the record year
it is just raining non-stop we are in February in Berkeley California so we got a lot of rain here
guys just every single night it's raining anyway when when I get rid of all this loose stuff I'm
gonna use a wire brush I'm going to hit weld Creed on it's a bonding agent guys cuz new stucco will
not adhere to a painted finish and again the most important thing is remove all the dust otherwise
even with a bonding agent it's not going to adhere so you want to get all this crap off I'm gonna
take a minute here and I want to get rid of all this loose stuff and all this loose stuff gotta
go okay that's about it when you see me again this is gonna be cleaned out I'm gonna go ahead and try
to remove any excess that I think is on because we don't want to fix it and then the loose stuff
have it occur again so when it rains guys houses lift then they drop when drier conditions occur
and they always do Plus this was a wrong finish anyway this is a - thrown on somebody put a float
finish and they brought out the sand or aggregate probably what I'm gonna do - cuz it'll match
anyhow when we get to that stage I'll show you folks okay guys we are at the stage well I'm gonna
go ahead and submit it over here it was about an inch and a half deep big deal I put accelerators
in it so this is set already figured I get that out of the way and guys if you have a huge crack
this was a huge crack right here see that white that's actually I don't get your fingers in it
it's uh that's I put some polyurethane caulking in it because it's an adhesive sealer and it tends to
flex more so I can cover that up with a cement okay so this right here this is just Portland
cement guys I've Portland cement three times the amount of sand for each for each each mix
basically okay so guys now that you got that done and look at what we're matching that's
a heavy finish so no caulking is actually going to match this guy's got to use a plaster stucco
laughter technically is for the word for interior stucco or submit classroom as a term for exterior
one more little thing now guys when you do this I would recommend you get a like home depot lowes
they sell a product called cement cement all makes it rapidset stucco so a rapidset stucco
it sets in minutes and it's got a heavy sand in it leave a bite in ten pound boxes twenty-five
pounds of big bags all right now that you've got that done guys you take a water bucket
water bucket and a sponge float the sponge float is this should set about 15 minutes to
an hour depending on the temperature right now it's pretty cold but I'll make it work anyhow
okay so you got that down now you got your green sponge float you've got to match this finish and
to here the transition is everything guys if you don't add takes it takes a little bit of time to
transition use the whole float don't use a little tip or so the whole float and get your top first
generally I like to do the top and I'm using the whole slope what happens if I use a tip you know
your gouget so here's the whole float and just like snowboarding guys use the whole the whole
float you want to go somewhere on a snowboard use a whole board okay now I got some residue
here what happens if I keep going it's gonna drag it I got to get this residue off so I'm
back in my float bucket put that bucket on here a little too much water in there but and I gotta
be careful usually I'll just slam it down like this get some of that water off of here because
the water will start this off again we want it to set now okay so with a clean float we know
there in the bottoms now feather in the bottom beautiful feather this bottom and pull it down
now I'm pushing it down guys push it down and then basically now I'm using the flat surface because
I'm pulling the a grit out with this sponge if I use a trowel I push it in I want it to match this
so this is actually a - finish it's thrown on but this right here will match it and again guys the
whole the reason we're I'm doing this is because the fellow said gee the Integrity's destroyed no
guys cracking or this kind of buckling is not really it's it's not going to compromise the
integrity of the stucco let alone the membrane and actually this is just a foundation there is
no membrane so anyhow you make it pretty when it's wet like this it's a little harder to control so
have you folks if you're watching let it dry let it dry I'm taking here this bucket here had half
the water I could slam it against it you don't want to do this because you twist twist these
ends down in this a real drag to make it work here I'm just gonna pull up I'm going to create
this corner and pull into it this already has accelerators in it so that's pretty much dried
then your your finish here pull it up pull it up and then now let's see what I what I've got stand
back look at it and just you need any details you see you say gee look there's a little hump
here there's a ridge here there's a dis that step back look at it and fix it now I can see there's
a couple little things here guys which I'm going to get out blood that's probably going to take me
another five minutes no need to you get the gist of what on saying guys just if you see it give it
some more time to set clean your float with water and make it so it's perfection anyway guys my name
