hi guys Kirk and Jason here with Kirk Giordano plastering, today I want to show you guys some
things because we get asked a couple questions one of them is how much water do you have to put
on a base coat prior to applying a color coat I thought good question and another question I
get asked not too often is somebody will call me they'll say hey Kirk I watched your video and we
did our scratch coat we forgot to put lines in it do we need to tear it all off and I'll say no you
don't need to tear it all off what you need to do is either put a bonding agent on it or hydrate it
well for the sake of answering how to hydrate a wall and hydrate that means wet it down mist
it water it hose it whatever you want to call it guy okay notice how that's darking it's darkening
because this is a cement Tisha's finish and just like a brick which is also submit tissue it will
darken when wet that's the beauty of a brick it lasts forever the color fades in a matter
of 80 years but it lasts forever stucco is the same thing now if you watch this in some areas
it's it's an inch thick we just we did this base coat about a month ago so this is an inch thick
now what's going to happen is the water is going to absorb into this wall quickly in some areas if
we were this to guys if you're in the hot Sun say you're doing a whole house a color coat you want
to hose the whole house down what I'll do is I'll generally look for area I'm going to start with
the color that's what I'll hose down first and then hose the rest of it down and the Sun plays
a factor too but for the sake of this I won't get into that now it hasn't been long but what
you'll see is it starts to dry out the top is starting to dry out the corner is starting to
dry out a little bit now if I were to just take a color coat and start putting it on here it's
not really ready for color coat at this stage I just hit it what I want to do is I want to give
it about 10 minutes and or 15 here's what I'm going to do to guys it I already know this is
going to start drying out what I want is I want this whole I want scratch coat and the brown
coat to be moist and I want it where we apply the color that that inch-thick takes about technical
about eight hours to dry out if I apply a color coat right now it'll dry out in about an hour
because only the top is wet so what I'm going to do guys I'm going to continue hitting this this is
what you guys would do if you're planning to do a color coat you see how it's starting to seep down
here guys that just means that that water this is this is new fresh and it's sucking in right
here one of the most important things you can do when doing a color coat you have to know how to
hydrate the wall properly and what I do is I just keep going here keep going what I want to do is
spend five minutes no I'm not going to put this for five more minutes while you guys watch but
you get an idea and we're going to start other things and I'm going to come back to this wall
and when I do you'll see it's kind of dried out a little bit and I'm gonna hit it one more time
just I'm going to miss it then I'm going to go like that and that way our color coat will adhere
it'll here by suction why is that so important guys well say take a color coat you put it over
a drywall now that color coat over a drywall won't get a good bond so you as fast as you put a color
coat on a dry wall it'll suck up to it and that texture and base coat will be loose it will come
off eventually so you've got to know how to do these things right for the longevity of a color
coat so I'll come back to this and I'll show you a little bit more all right guys it's only
been about 15 minutes but the Sun is starting to shine here so we're going to lose the ability to
show this accurately notice all this right here is pretty dry the water and both the base the
scratching a brown is starting to come down that's what the weep screed is for it weeps out so I can
see this is still wet down below so that's fine what I'll do now is we're we're ready to go we
actually started on another wall but we're going to come here again the same thing applies I want
to put the wall he water on here and I wanted to be able to drip down I want to saturate this wall
I wanted to slowly dry why because I want a good suction for this cement Tisha's color coat finish
we're doing and by the way over there you see Lou he's got the color coat coming that color
coat comes usually in three are three textures this is a heavy texture it comes in fine medium
and coarse so for an example okay if I was to put this on right now what happened okay I'm putting
it on a surface that's too wet but it just shows my time in because I made it work normally if it's
too wet guys it just starts falling down but I'm used to this stuff anyway the water right here you
see it's starting to drip through here and it will bleach out the color right now there's no
color in this it's just pigment because they're painting but you see all that water it's coming
right here and if there was a color in here any of the colors except for crystal white it will
bleach the crap out of that color so the idea now is to wait until all the waters come down
and that does take practice guys I mean it takes sometimes 20 years to 30 homes to learn how to do
this properly so if you make a mistake it takes so Kirk a long time to do that too so anyway I'm
going to scrape this back off because I'm trying to give you guys an idea of when to put that color
coat on and another 15 minutes this wall will be ready how about I just say that and lastly
guys I'll point out something over here where if this wall was painted now what you would need a
bonding agent a lot of you guys say I can't find well Crete anywhere it's made by Larson's guys you
don't need to use Wells Crete I use weld Crete because it's blue and I can see if we missed
an area quick right quikrete they make a good bonding agent Sikkim makes a good bonding agent
but that's only for House sets painted you have to pressure wash first very well because nothing to
here's the dust then you use these bonding agent but this cementation finished we're putting it
over a base coat we do not need a bonding agent it adheres through suction and that's what this
whole video is about how to apply enough water to create the suction we want anyway I hope I didn't
confuse you guys too much but that's there's no simple answer to hydrating these walls prior to
the color coat my name is Kirk Jason on the camera we thank you for watching and as usual
