good morning folks Kirk here with Kirk Giordano plastering, what we're going to show or actually explain
today are cracks, I did this wall a month ago and we've done everything up to specifications on
this a sheer wall we did a scratch coat we allowed that to set we hydrated the scratch coat we Brown
coated it a week afterwards and we hydrated the brown coat now I still got some hairline cracks
however these folks sheetrock after all the stucco was done if you're gonna sheetrock sheetrock prior
to the brown coat you can sheetrock when we have the scratch coat on but vibration causes cracking
not sometimes but every single time if you're pounding on a wall inside or outside you're
gonna cause hairline cracks on new or existing stucco so the point I'm making today is do the
sheetrock prior to the second coat of stucco and absolutely before a color coat anyway these these
cracks are very hairline and it's early morning I'm here before the Sun comes on there if I allow
the Sun to come up say 4 o'clock this afternoon and we are in Orinda what will happen is these
cracks will shrink so if I caulk and when they're shrunk the next morning they'll widen and it will
be like I did no good I'll have to come back ok a lot of people say Kirk every time I do
cracks repair you can see the line they do make more flex more flex has got it's it's a mortar
stucco and repair with sand in it so it's got sand in it it's rubber and this is pretty good
stuff personally I'll go with the Sikaflex the polyurethane because it's even better now what
I'm gonna do is I'm gonna show you how to match well I'm gonna show you how we match finish where
it's sandy okay I'm filling this up and what I'm doing is I'm putting my caulking in side the crap
I'm squeezing it inside the crack and now what I'm going to point out is guys like me do the stucco
and then do the talking when the caulking is done say if I just go to one like this
this is a can you zero in on this hand oh yeah get close okay this will show but now if I use
my whole hand and I rub it like so now I'm rubbing it then going in circular motions
these circular motions here will blend in and I've done this at least 500 times not only some
of my work what other folks work because call me all the time for craft track repairs track
repairs and there you have I mean I've got on this edition we've got maybe maybe 10 or 15 of
these I expected a lot more if they've done the sheetrock afterwards you're always supposed to do
the sheetrock prior so I mean there's there's many many many reasons a house will crack engineering
structural settling rain but this particular one is the sheetrock so again my advice is always do
the sheetrock prior to the scratch coat if you can if you can't well do it prior to the second coat
otherwise that second coat will crack vibrations anyhow that's that's what I wanted to show you
folks because I'm already here and I've gotta do a few of these little cracks and again it's early
morning that's the best time to do crack my name is Kirk I'm with kirk Giordano plastering, thank
you folks for watching thanks Dan for doing the video we'll see you guys on the next one.
