Howdy folks Kirk and Jason here with Kirk giordano Plastering.
today I want to show you about caulking in the description usually I'll do a video and describe
what we're doing but in the description there'll be a long drawn-out description of why stucco
walls crack after like 40 years and being in the trade you know just be about ten paragraphs is
why it'll answer every question that I won't answer right here see this wall right here
it it's blended into the concrete so concrete is normally three inches thick and it's pretty
strong we're stuck with one inch stick so when it rains it lifts the house and when drier conditions
occur it settles and when it settles we get this kind of hairline cracking and they've talked us
a couple times and it keeps cracking so I told man I'll just put some more flex in there and by
the way guys there's about 20 different Caulkins with sand in it and yes you are paying for sand
and caulking this one here is more flex because it looks like it looks it has a sand and it's
the right sand to match this particular finish now what I was telling him is we can go ahead
and we can fix this right here and fix that and fix this crack here but what happens is a lot of
times it'll buckle in a buckle because something's got to give either three three solid inches or one
inch so you're just you you you tap the wall oh let me see you hear me I see a little bit of oh
okay I see why it's cracking now oh it's cracking because they've got stucco on stucco you know what
guys that's not a great idea but at least this is where the weak spot is Wow okay I open a can of
worms but that's okay is nothing we can't handle generally what you do hey babe wait one second I'm
gonna wire brush this and I'm gonna take some of that mud you got right there and fix this
okay, melon just gave me some mud here now. We're doing an addition in the back,
so we have the mud already mixed, and plastering guys is all about
improvising if you find something that you just didn't expect. Oh,
here it is. I didn't expect this, so this is also why you get buckling to getting back to the crash
and by the way guys what I had to do here is a wire brush it and I hit it with a bonding agent
otherwise this do Portland cement is not going to adhere what I'm gonna do now is just put a little
bit right here just because there furth out and I'll get back to what I originally was showing you
guys and that is crack repair and again in this video I'll have you right now we're getting ready
to go home and I told the owner that I fix these cracks but there's a lot of Caulkins with sand in
them so the sand actually makes them more stable and and to what you want to do is a really good
deep fill this stuff up and again I'm using more flex but there are so many different caulking in
fact a lot of people say hey Kirk what about the caulking is that are made for grout and now I'll
say you could use those caulking but they're the grout is finer sand so when you're trying to match
this stuff here you can see it's a very heavy sand and like this crack here that I originally
was starting to point out all you have to do is put it on there something like this guys I don't
know if the camera even shows it but this is a hairline and paint will like fill that paint will
flood those that crack so what I'll do is we'll we use this I like to use more flex because you
can use your hands some of the caucus you see us use for stucco like the Sikaflex two one A's those
are polyurethane adhesives so the polyurethane adhesive sealants the professional-grade stuff
you can't use your hand like this it just it won't it won't go in it won't you really can't
float with it basically and when I say float I mean you can't float it in because it's it's
too sticky so you want something that it's more of an acrylic what's an acrylic it's just water
base so these acrylics right here the water basin you can put it on like so take a take a float and
just bring the sand down the aggregate again yeah you're paying for expensive caulking with sand in
it but it looks a lot closer to the stucco then the actual stucco itself or the the smooth I say
a lot of guys that will use the smooth and that if you use the smooth caulking guys you'll have
a smooth patch in it it just won't look right there's a lot around here but I don't want to
show other people's work so what I'm doing now is I'm just because I had to improvise and stucco
is all about well all the trades are all about improvising you see something that's wrong fix
it fix it and I just now spread this I should give this about 15 minutes but we're getting
ready to get out of here it's been a long day so I'm gonna finish this up right now and again guys
in the description if you have time and you're wondering man why do walls crack I'll tell you
40 years some are in the description of why all stucco cracks it's a long long summary but you'll
find it if you have any questions about cracking it will answer them because I've been doing this
a long time anyway guys that's that's how you repair cracks there there's nothing to them
I'm gonna go ahead and finish this crack right here because they used a silicon guys you're
not supposed to use a silicon because if you use a silicon and use your finger it shows and then
you can't paint silicon so anyway guys my name is Kirk Jason on the camera we thank you for
