hi guys Kirk and Jay here with Kirk Giordano plastering, today I want to talk about caulking
2016 now I did a video back in 2010 and people keep responding to that I said man that's an old
video they've come up with new stuff since then I'm gonna briefly describe what we use and explain
it you guys are you know welcome to use whatever you like here's I mean when I'm doing paper and
wire for the average stucco contractor plastering contractor you want to use this for waterproofing
everything this is it's a Sikaflex 1/8 and what does that mean it's a polyurethane caulking it
flexes it stretches and it seals when we're doing paper over a house and we come to a window we seal
it we seal the paper to the frame or we seal the paper to the electrical outlets pipes vents you
name it and this stuff is so strong you put it on two bricks and you put three drops you're not
gonna be able to pull those apart where there's another product what made your hardware stores
they're not gonna mention any names you can put a whole tube and it says it's designed next day
pull it right apart garbage but these are some of the better project products I've worked with say
okay so the Sikaflex we buy this at the quality yards like west side building materials or true
and wide Bigby lumber you're not gonna find this at Home Depot or Lowe's but you will find their
sister product at Home Depot or Lowe's it's stuff right here it's pretty good stuff the same it's a
construction sealant and this stuff it's a real drag to work with guys I'm gonna show you what
a drag it is because you need denatured alcohol to clean it up or say thinner you can use acetone
you can use any any of these products but they're all carcinogenic so you put that on and if you try
to smooth it out with your hand sticks to your hand sticks to your pants stick to it sticks to
everything okay let's get off of what I use to waterproof most of my jobs with and let's get
on a product that actually is for cracks say say one hour stucco say like this is one of our walls
now this has got a sandy appearance so it's got a texture on it I like this more flex and more
flex when you put it on it has a gritty gritty texture to it because it's made with sand yes
you're paying for a lot of sand in this tube but you sometimes need that this does not have sand
although they do make a product by this company with sand hated it because you can't work it you
can't float it or do anything with it lastly I'll show you and by the way guys if you're repairing
they like us if we're doing a scratch in a brown that brown coat is going to crack each and every
time because it's normal that's the normal drying process so we'll come back sometimes if it's a
painted finish and we'll just put some of this more flex in it match it in and it'll give it
that look that we want and hide the crack that's normal they do make a lot of other crack repairs
for concrete's I use these I've had them they got the mortar mixes you name it I'll show you what
Jay and I use - for interiors Jay does a lot more this interior cracking than I do or into interior
crack repairs Jay's he does a lot of more interior work than I do of course it's on the camera it'll
use this right here it's a 40 year and it's an all-purpose acrylic latex why because this is
easily clean up a bowl I'm going to show you in a minute how easy this stuff goes on and it
cleans up so easy I mean soap and water you clean this up soap and water you clean this up you need
some serious materials like thinner or denatured alcohol to clean that up but each thing has its
specific purpose it's a 40 year now one of the things is we use a 40 year exterior caulking for
insides why it lasts longer I wouldn't use an interior 25 year for outsides but I will use an
exterior or inside it just lasts longer guys so okay what I did the other day was I put a couple
screens together guys and I put a huge gap in it all these Caulkins right here say that you can
go 3/8 max in width and depth so I went one inch and I went one inch wide to show you what happens
if you go thicker than what they recommend what happened does the wall implode no it just shrinks
and you just put another coat another day so this is Sikaflex now that was done yesterday this is
more flex it hardly shrink these two hardly shrink this is the 40-year stuff it shrank a little bit
but that's ok this is used for interiors anyhow the 25-year interior caulking guys or the 35 the
25 will sink less than half of this so you will have to go 2 to 3 coats with that stuff the 35
will also shrink so let me show you this stuff here now this is some nasty stuff and by the
way guys before I forget everybody knows that a caulking gun say how's it cutter you it's usually
in the hand oh you you put it here you cut it boom you've got your cut and most of these guys have
their own poker too so say say like this this gun right here they all have these so they come with
the cutter and the poker most of them I got so many guns it's it's hard to keep up with all this
stuff but let's just say for example here this Sikaflex and man this stuff is so strong but it's
a it's a nightmare to work with guys I'll show you why okay let me get the angle right I'll get
the angle right you squeeze it in you squeeze it in just like so guys now this stuff is what more
professionals use than probably any other caulking I guess because we both I've been using it for
years and years never let me down like 30 years this is the stuff guys but man it's such a drag to
clean up you have two buildings next to each other you want an expansion use this stuff but you will
need denatured alcohol let me get a towel because say like say like something like this all you're
gonna do is use your thumb and clean it up just wipe it on something your thumb everything I'm
wiping guys this stuff it won't come off this this towel here is garbage and not because I'm just
using this it's just a throwing a throwaway towel but you notice everything on my thumb here if I
don't get it off immediately this stuff it's very powerful it's one of the better professional-grade
Hawking's there are but it it has its benefits and that's waterproofing and adhering things let's
go now to more flex more flex I like because it's it's easy I mean if you don't need any say dinner
or denatured alcohol or anything weird like that this stuff soap and water go to the nearest spigot
clean up okay so for example you put that there now this one a clean up real easy I did this the
other day and it shook up a little bit big deal big deal squeal what happens if you use a caulking
and it shrinks up nothing you just put on another coat the next day it makes me laugh well people
say hey I put this on in a shrink Kirke like so put another coat on big deal okay the interior
and by the way this this one here you can float say well while I'm at it guys let me show you
this okay you put some on a piece of wood okay say this had a big ol crack on it and we'll use for
example my sample here as a trowel you put that and your trowel it down now you take a wet sponge
float up alright you take a sponge float and you can sponge that and you can make it you can make
it a sandy finish so if you have a stucco project just bring it up bring out the aggregate bring it
out you cannot do that with the Sikaflex lastly I'll show you what we use for interiors and again
guys we with this stuff here we'll we'll seal the cracks inside our Jason will he does a lot of this
stuff people call me and they say hey gee I got an interior Jay Jay generally will take that job and
go do them because he doesn't mind that tedious stuff actually quite good at it too you can trial
this you could brush it you could float it you could do anything with this stuff here and it's
easy to clean up say for example you say well man I'm gonna paint it and you can just you can paint
it even this stuff here is so easy to work with boom I mean that's done if you had a big crack
and you want to use it put it in a in a crack and then use a trial you can but you could paint
it also for safe corbels or rounded details this one I just did here - you could paint that - gives
a better finish this I put my brush in here I'll throw this brush away because I'll never get that
stick up out of this thing here we use a lot more caulking x' than this but guys but since you folks
call me and say gee Kirk hey what caulking do you recommend for this or that these are the ones we
use and I've been using them quite a few years they've never let me down if a product lets me
down I'm done with it so and again guys these are just a product that I recommend you folks I'm not
obligated to any product nobody endorses us to do anything but we use them we've had great success
over many many years so I thought I'd pass this tip on to you because you guys seem to value my
35-year opinion anyhow my name is Kirk Jason on the camera we thank you for watching and as usual
