Hi, guys. Kirk and Jason are here with Kirk Giordano plastering.
today I want to show you guys some interior stuff a lot of people call and say, Kirk, can you
show more interior stuff. We show about one out of ten projects we do. so we're trying to show we bit
more anyway. I'm going to show you some old wood lath, this timber lath or redwood lath whatever
you want to call it guys.
it's old wood lath and it's tacked on the studs every three-eighths of an inch three millimeters whatever you want to say it with, as long as our plaster goes through it's
fine. Now this board right here this is blue board what, what I'm going to do is, I'm going to skim
coat this as I skim coat I'll explain what what we're doing and why, now this gives me a chance
to keep working and do a couple of things at the same time, now this, this blue board I'm covering, oh you
say what is blue board what's gypsum board what's sheetrock, sheetrock is gypsum board
gypsum board started right after the old lath and plaster,so gypsum board technically replaces
lath and plaster now you can call gypsum board sheetrock or drywall means the same thing guys.
Now questions people are always asking me what's the difference between green board blue board and
sheetrock? well as I said a minute ago sheetrock all that is is gypsum, so green board now that's
made for bathrooms or kitchens why? because it's a a little bit more, well it's water-resistant, notice I
didn't say waterproof. Because that's the dirty word in the industry nobody says their products
are waterproof, they say the green board is water-resistant and mold resistant. now you might have
noticed I'm going over a blue board right here what's the blue board for well if you go online
you can spend hours trying to figure out what the heck blue board is for. But technically it's made
for plasters, veneers in particular there's a lot of veneers, you can go with Diamond, Keens just a
a ton of different veneers and no I don't know the names of all of them, but make a long story short
yeah say for example this wasn't blue board and it was just regular gypsum board, you could put
Plaster-weld on it guys, this stuff here, Plaster-weld and it'll adhere any product any tape
and mud you use, any compound you use, any veneer plaster you use, so it's kind of overrated but we
we do a lot of this stuff where we'll skim the blue board or the green board or any of that
stuff, I'll show you something while I'm at it because I got to let this set, now technically
I was going to do this whole bottom here, wrap around we got some weird thing with this pipe
here pipe was showing, so we're just reinforcing it with mud on the top of the pipe then some fiber
mesh on top of that really well get it secured so this is going to have to set for about. We
get one more scoop on here it's gonna have to set for about a minimum of 10 minutes before
I could rod it, but I'll show you something in regards to the blue board since I'm encountering
it on this particular job.all right over here say for example now this fella he's got on his
bathtub here he wants to waterproof the bathtub. Who doesn't? well it's an old-fashioned tub the
surrounds here are just as round as this that does not have the flange that goes up an inch
so, I mean you put the blue board but on it and I said well gee whiz man what are you gonna do
with the blue board, you can't plaster it, won't waterproof it. He says well the guys are coming
they're going to put um say like a Vycore or on here Vycore or is like this peel-and-stick stuff. this is
DuPont's peel-and-stick, it's great stuff it'll stick on to the flange and of course, you got a
perfect flange, that's either with some goo gone or some denatured alcohol, you prep this real
well you stick it here you come up getting back to the blue board. was it necessary for this no
because technically he could have put any kind of board here. Green the blue board, again as I
said earlier it's for veneer plaster, but what they're going to do first is they're going to
put a membrane on here whether they use Vycor by say , what's this grace product whether or not they
use Vycor or some DuPont product it doesn't matter because they're going to put this here
then they're going to screw wire on here then they're going to plaster that but they're gonna
waterproof this. anyway so the blue board wasn't really necessary I see that a lot I just figured
I'd answer that question personally on my own house I just went and I put a plywood then. I
put my Vycor or on it and put wire and skimmed it took me about an hour and it was prepeed for the tile.
anyway getting back to this guy here now we're not really ready for it but say for example you
could use a truck Darby here now you take this wall to this wall and you just pull it up and
that kind of gives you your grounds where you have something in the way such as that light
you just tilt it a little bit oh that gives you your grounds that's all true and plumb right there
and I got all this excess mud that I'm going to put right back in the bucket like just set that
there because technically I still need that to set a little bit now what I could do also is I
can take a big swimming pool trowel now this is my Congo trowel notice guys it's not completely
round its square right here it's straight right here and it's just the corners are arched that's
it but this is flat it's a five inch 20 inch trial most people too big for you guys to
use it but for me I like it because it's like using this Darby here I can take it and I can
come here half take half of this wall and I can take the other half right here say and yeah make
it pretty of course when this sets another five ten minutes I just go back over it and get all the
lines out now to give me a straight finish like that anyway guys we're still busy here I'm going
to take this all the way around here I thought I'd point out because we have blue board in here what
the difference between regular sheet rock blue board and green board actually is anyhow my name
is Kirk Jason on the camera as usual we thank you for watching we'll see you guys on the next one
