Hello folks Kirk here with Kirk Giordano plastering, due to many emails of folks asking
me how do you fog coat, I'm going to put together a video on a fog coat. Do I fog coat anymore? No,
generally when we do fog coatings for a large wall, where we have scaffold, and there are two guys
on each level in the heat sometimes, you'll see scaffold joint, and when I first started in the
trade 20, 30 years ago I used to do a lot of fog coat to get those scaffold joints out, I do get a
lot of calls from condominiums and homeowners associations, which say, gee, we want a fog coat
as opposed to paint, well if you're going to do any color coat or paint, a fog coat is simply to get out
differentials of color usually anybody who wants to change a color using a fog coat, good luck, but
don't say I didn't warn you, all right can you zoom in, this is a La Habra color chart there's a lot
for color chart, now and it's a lifestyle, lifestyle, what does that mean? well, first of all I'll show
you, this there are a couple photographs that La Habra has it here, in this middle photograph it
has a big wall and it's obvious there's so many variations in the color code because here's your
standard color code mix two pounds and a 100-pound sack or ninety-four-pound sack. we use one of these
per sack for color code but special order colors can come in five pounds could come in nine pounds
I've seen them coming 11-pounds and when you're mixing that much color pigmentation, we are going
to get varied colors, say even small walls even if you're good and you know what you're doing
you put this much color pigmentation into a ninety four pound sack of color code gives you a bunch of
variation some folks love that some folks hate it so what I'm going to do is I'm going to show
you how to fog coat, because I have so many fellas, asking me how to do it, you order a bag of fog coat.
Fog coat is sold everywhere, Close, in Hayward, Alta building supply in Oakland or West-Side, they all sell fog coats take this 25-pound sack, they put the entire contents in a five-gallon bucket,
put three gallons of water, you mix it I'm going to use the drill here to mix that, and then you
let it slack let it sit for 20, minutes and you put another seven gallons so you end up with two full
buckets, back and forth mix that again after you how to mixed up like a milky consistency or fine
it's got it's going to be will real watery, why? because then it goes into something like this, a
a lot of ways you could use it in airless I prefer and folks like me in the industry, prefer to use
these Hudson sprayers, Here's a really important tip, triple screen these with the nylon paint
screeners, because one grain of sand will screw up your whole day, and what happens if you get two or
three grains of sand it comes in the tip here and instead of giving a nice beautiful mist, it'll just
spray in one direction and it'll saturate a wall it just screwup the whole finish, so that's, that's
real important, when we get to that stage I'm going to show you how we fog coat on a wall, and show you
what it looks like and why, and go from there, but, again I showed you how to do all this and when I
might as well show you this - prior to getting out of the wall there because it's kind of dark
on that side when you're misting, it's a good idea to say mist the wall to with water get it
a little wet, yeah, and then when you come to do your first coat and don't put it on real heavy
you put it on real heavy in one spot it's going to be chalky, in you'll be able to take your hand
see it come off so how you really do this is you go corner to corner every corner to corner
you don't just do one little area now you go in circular motions - after I fill this Hudson
sprayer up I pump it up and give it some pressure, then I take circular motion I just go like so, I'll
show you soon enough we do the whole wall then we come back get it again in most cases you can
do two coats usually, I have to do three, in order to get all the walls just perfect perfection now
if you're going to do the three coats like this, it doesn't cover things like this, you ever crack
won't cover that crack, so you're spinning your wheels if you want to fog coat something with a
crack and if you just you think well, gee, I'll I'll fill this with the right color and then
fog it, you're never going to get that bright color out of there it's all coating again, is
it's kind of a lost art, my personal opinion, stucco actually I found in 30 years contrary to
some of the literature that I read, they say it darkens with age, I say it lightens with age, and in fact, I'll
show you over here this color code is about 70-80 years old, anyway I'll show you that, and show you
how once I get everything mixed up how we apply it, and why, okay guys for the sake of explanation
purposes, all hearts, and sprayer is filled with air as much as we can pump it up I'm going to try this
sprayer here my original one failed on me, I won't even go to details, it's too long I'm using a tip that
generally is used for pressure washing because we are going to pressure wash, that's why I have
my tip, but I'm giving you an idea you'd see it go in circles like this and the more times you
do the color comes out a little better each time you don't want to go too heavy now generally what
I would do is I would go to another area on the wall because you don't want to put too much just
like that, I'm going to run out of pressure in a minute and I'ma have to use the Hudson to fill
this back up because this just hand pressure here you see you go over and over it like so and the
color I'm spraying on is actually called silver gray, let me get,t get back to the pumping and I'm
going to give it about 50 pumps left-back again after I pump this guy up again we're using silver
grey, on this and this is just to prove a point generally, you're going in circles like this and
this tip from a pressure washer isn't as good as my original tip so this is how we fog coat
we just keep going in circles and as a rule, I'll hit the entire wall and then come back again but
as for explanation purposes, I'm showing you this the way in every texture, say if you float finish the
wall, you skip trowel, you put a dash finish each one has to be special ordered, I would recommend
if you're going to do this to bring it to the material yard and say special order this color
tell them exactly how you that color the type of sand the texture you use because everyone is
different when this dries here it's going to be uniform it's going to remove this right here it
will remove this light spot and it will blend it all in, but if I was going to do this for real, I
would give this about another half hour and then I come back and I lightly mist it again, one more
time and that is how you fog coat a wall windows doors should always be covered this is a porous
material it won't stick to metal but who wants to clean metal cover everything otherwise you
will be cleaning windows doors even these I even cover these when I do this I haven't done a fog
coat in about seven years and hopefully I never have to do another one, but again enough of you
folks have emailed me and said how do you do it, well that is how you do it and it comes actually
with a different kind of tip but we it provides a lot in our trade if you have any questions on
what I'm saying here if I missed anything email me and I'll fill you in and again I highly recommend
fog coats for scaffold joints only, but there's always somebody says I'm going to do my whole
house and change the color, good luck. My name is Kirk I'm with Kirk giordano plastering, we're
going to get back to what we originally started on this job, we'll see you folks on the next one.
