hi guys, Kirk and Jason here with Kirk Giordano plastering I want to show you folks today is
fellow who L in the house he called me says G Kirk I got a brand new color coat separating from the
wall and looks like there's a lot of efflorescence what is efflorescence that's just the residue
or after it starts to dry the salt bleeds out but that's not what's causing this what looks
to be a fluorescence efflorescence usually porous products to concrete cinder block this is painted
so I looked at it I said well it looks like you had a fella come out here and just do this within
2 years ago and I'm not sure if it's an acrylic because it has a sheen to it but it looks cement
ish as' to me also if as you're right they did a cement Isha's finish and then i painted it a few
months later anyhow what I told them is well it's separating from the the house the cement ish this
finish is separating from the painted surface so I said well just by looking at it I can't really
tell you what's going on there I have to do at least one test spot I said best case scenario is
you'll do about will do it knocking you hear this that's the finish coat that's separated hitting
the painted surface hollow sound here different here you can you can hear the top coat so anyhow
what I told them is let me pull off one area and and I can see already what's what's going on now
first time I was here yesterday I was just looking at it and I try to come up with an idea of what
what's happening and usually I don't tell folks see here's what you got until I could at least
do a a sample on it he told me said well Kirk I got a guy who said he'll remove the whole lower
half for 900 bucks again I don't normally discuss price on this but to prove a point he said I got
a guy says he'll come he'll remove the whole portion of the wall 900 bucks and redo it and
then I just repaint it that's not a bad price cuz I told him 450 to just do some spot work
but I wasn't certain how far it would go now see the rest of thats pretty pretty hard why did this
separate in the first place let's go to a spot that I just left two minutes ago you can see the
efflorescence happening here and again listen for that hollow sound solid hollow okay getting back
over here I told him I said she tell me something did you did they pressure wash the house he said
no they they put some blue stuff on it and they just did the finish and I thought man okay the
guy he wasn't a stucco contractor right he says no I wasn't a stucco contractor because if he was
a stucco contractor he would have known through this product here it doesn't matter what bonding
agent or liquid lath as we call doesn't matter which one you use is about 20 nothing sticks
to a dusty surface not even an acrylic finish it won't stick to a dusty finish how do I know this
finish was dusty well there's the bonding agent on the cement tshis finish itself and plus the
cement tshis finishes a quarter inch thick another big no-no you don't want to go that thick that's
almost I thought they were browning but anyway now that I see what's what's happening here to these
areas now I can tell them G over there I come to a stand point so if a fella tries to take the whole
bottom off not all going to come off it's going to come off in patches here and there and you
just have to patch it if you tear the hole if you try to tear the whole bottom you're going to end
up with what I have over there even pressure washing is not going to do it some areas have
adhered well some have it we're on the southwest side where it gets all the Sun and so it's being
baked on and if we're in the middle of summer and the guy says well what's the worst-case scenario
is I said worst-case scenario is it's going to continue to buckle and pop here and there on
this wall you might get lucky over there and the idea guys is always pressure wash a house first
if you're going to do an acrylic you pressure wash then you use that acrylic primer if you're
going to use a cement tshis finish you pressure wash then you use whatever type of liquid lath
or bonding agent you prefer I'm going to go ahead and wrap these up because I see what I needed to
see here in order to even bid this job but I'll show you how we do that - okay guys for the sake
of putting it back together what I'm doing is I'm getting all this dust off and then a lot of dust
on this wall so that proof well the owners told me that they didn't pressure wash you guys have
got to wire brush it well and it faceted pressure washed in wire brush a whole house and with the
pressure washer you kind of score it just like what we're doing here so all I'm doing now that
I found out what's going on here is putting it back together and as long as there's dust here
nothing will adhere to dust no pain so I get that I get the can of this and I'm actually just since
I took this apart I promised the fella I'd put it back together once I knew what the heck was
here because he may say gee Kirk I want to go with that other guy and have them try to take
the whole wall apart and what my experience in the past is if you do something this goofy and
believe me I've had 15 guys working so you can't watch everybody sometimes get into this stuff it's
really hard to just say I'm going to take it all off it could be chiseling for days here or
pressure washing and not all of it come off anyway what I'm doing is I'm just matching what they have
here now this material I'm using is it's a heavy grit 16 20 there's three types of material there's
smooth then there's fine or smooth which is also considered fine then there's medium and coarse
they have coarse right here the heavy grit it's called again 1620 so all I'm doing is temporarily
matching this because they are going to paint this it tends to drag right now but that's okay just
take it here and feather it in give it a little little drag like they did they actually when they
did this they applied it floated it then textured it I'm doing it this way because I can and all
this is going to come off anyway just again needed to know what the heck was going on here anyway
guys we're going to do a color code cementitious or acrylic or a paint job you've got a pressure
wash your house well usually 3000 psi if you want to see which pressure washes we prefer we do have
videos on that too where we show what pressure washes are the best for that and just put how
