Hi guys kirk and jay here with Kirk Giordano plastering today I want to show you guys is
proper ways to pressure wash and the pressure washer we use I have several and they all have
different purposes guys let me show you what we got here okay this fella he wants to do a mural
on this he wanted a steel trowel finish meaning as smooth as possible then they're going to paint
some pretty designs on here now the retaining wall is made of cinder block the cinder block
is about 70 years old so there's a lot of ways to clean this guys I'm going to show you the
simplest way you can come out here with the water hose and wire brushes and spend half a day to do
it or you can have some electric pressure washers which you'll spend another quarter
of a day or just use a high-powered gas pressure washer like the one we have here with turbo tip
that really cleans it the fastest anyway what do we got here say for example we got a whole
lot of efflorescence everywhere and we got moss growing all over this there's so much Moss dirt
dust and grime that the camera is not going to pick it up I can't even hardly see it but I do
know one thing I want my finish to adhere for this retaining wall permanently 30 years from
now I don't want to get a call from still alive it's a Neikirk some of that plaster you put on
came off the only way it's going to adhere permanently is if we clean this properly so
that's what we're going to do I'm going to take you back and I'm going to show you a couple of
machines hopefully we don't get drowned out by my own pressure washer we got going on
all right over here I'll just chase that notice does about ten or 20 different electric machines
some of them range from 800 psi to about 15 to 18 they're okay they work well for a lot
of uses cleaning cars motorcycles and stuff but a gas-powered one notice I got the gas-powered one
way over there why because it's too loud it'll drown me out but that gas-powered one puts out
three thousand psi and the tip I have on this particular nozzle excuse me Carl Carl has been
doing this this is this tip right here is a turbo tip now it creates a lot of extra force and what
we want to do guys is we want to etch this if say for example this was painted or a lot of
people call me as the Kirk I have a house that's painted or block wall that's painted how do we
remove it do we sandblast them glass hasn't been done in California for about 20 years
that I'm aware of so what we use is this right here about 3,000 psi if for example the wall is
painted and you're trying to get that paint off and you can't see it coming off at least this
will etch it so then you apply a bonding agent and that's that's good enough where the plaster
or skim coat will adhere or even a color coat if you're doing a house on a painted surface
I'll show you a little bit what this does okay now as you see it's going in circular motion
and all I'm going to do is continue to go here I'll start from the top work my way down where
it's got efflorescence I'll do the best I can but you see you see how it's picking off the MA
and by the way guys if when I hit the brick I hit it with a fan like this if I hit this brick
too close it'll it'll score it we don't want that either so that's the proper way anyway
that's that's the proper way to do this guy for all your folks who called me and you have all
this paint all over brick block rock and you say gee Curt can you pressure wash it off we can but
I usually unless unless I know if there's letting that I can't pressure wash it therefore I suggest
you folks go to Home Depot or Lowe's and you rent a pressure washer that has at least 3000
psi especially if it's a painted surface and an etching you won't be able to see the etching but
at least our bonding agent on an etch surface when you properly clean it allows our next coat
to adhere strongly okay guys now that that is pressure washed well I give you a couple other
tips that I didn't think about as I was actually doing it a gas-powered one and you guys can rent
these anywhere it has way more psi pressure pounds per square inch than an electric one bar none that
I'm aware of now there's another tip to guys unblock what I did is I hid it this way then I
came back and I hid it this way and the last thing I'm going to point out guys is we're gloves wear
goggles cuz stuff can go in your eyes and under no circumstances touch the tip a few years back
my daughter Madeline was pressure washing some walls for us and I said baby whatever you do don't
touch that tip half hour later she'd come running up she says hey dad looked at me real serious and
says she could wear those band-aids you have and I said you touched it didn't you so common curiosity
means you want to touch it but believe me guys with this particular pressure in this so called
turbo tip it will take the meat off of your finger down to the bone don't do it Oh Kirk says don't do
anyway Jason and I thank you for watching and as usual we'll see you guys on the next one
you
