howdy folks, Kirk and Jason here with Kirk Giordano plastering, today I want to go over
a topic I did about two years ago. it's a scratcher now with that scratch your video man I got a lot
of questions that I didn't think of when I did that video anyway this is a scratcher I've been
in the trade since I was 20 I'm going on 59 next month it's over 40 years anyway I've never heard
anybody call this by its proper name scary fire like well that fire is blazing it scary scary
fire SC AR I fi er why because it's a stupid name but if you type in and folks say Kirk I
can't find the scratcher well I did my own search and I typed in scratcher and it showed people
scratching themselves like if they had fleas or showed lottery tickets or it showed those things
that cat scratch so this you'll never find it if you type in scratcher type in scarifier now what
I generally do when I worked Union we we were fast with these things I would tape them prior and what
that means is just like this we we start our day I put the the groove where I want it come back over
it with the tape and this way it kind of gives me an idea of the depth now you can scratch anywhere
between 1/8 to say 1/2 inch if you want now that's that sealed that gives me an idea where I want to
the death it's kind of like working inside if you have if you worked inside years and years
ago or you're redoing old lath and plaster the old cedar laughs its spaced about 3/8 of an inch apart
and so the the plaster it goes through those keys and it mushrooms on the back well what we're doing
here is not going to go through any keys nor is it gonna mushroom through the back but it's gonna set
in the keys and that forms a mechanical bond act actually quite stronger than say a bonding agent
we're real and here's all you do guys you're gonna go horizontal now the question that was asked to
me was hey Kirk when I see guys who are showing in the UK or other places that the scratch marks
are wavy and or vertical now guys here's what I've been taught now some people will do like
this and notice that tape is the tape is us it's stopping it so it's not two things if you want to
make pretty designs like this guy I don't think that's any harmful but the idea is to scratch
it horizontally hear that tape acts as a guide so I don't have to take a sponge flow and by the way
what you can't see is the fact that we're just put about an inch and a half of mud on this and it's
already setting because it is a really hot day but to keep moving on and explain a couple things as
far as the directions of a scratch mark and the proper terminology to find these guys here in our
description in almost every video we have Amazon site you just click alright guys lost my earpiece
anyway in our description in every video we do you could you can just click on the link there and it
shows you the best ones to buy at the best prices one important thing is that folks don't realize
unless you're in the trade is hydration when this sets for two days of course we do same-day stuff
we're gonna do this wall today but if it sets for you homeowners in two days now you hydrate it you
soak it you soak it so much that the water stops absorbing and it just runs off then you put your
new stucco over the existing stucco it goes in between the scratch marks that creates a
mechanical bond a natural mechanical bond between a porous stucco and a new stucco that they just
together absorb together you have no stronger bond than that you not even any other bonding agent and
besides the bonding agents are used for putting stucco or concrete over painted surfaces right
now this is not a painted surface we're going over wire so as we go over the wire it's important to
to know why how and do's and don'ts and things of that nature we're about to take lunch then we're
gonna come back and put our second coat on this but that's advanced stuff guys one last thing
when I worked Union just to prove a point okay now say this wall was like this I kill time and I'd go
and big humming I was walking between scalpel and you can't really see that but it says USA I
remember the guy said alright man who's doing all this USA crap the idea is get some lines on there
that way when your mechanical bond your next coat goes on it it absorbs in those grooves so
it's not so critical guys whether or not you're going wavy or you're going exactly horizontal
mess is it's not that super important but I say go horizontal and never go vertical anyway guys
I thought I'd explain that because we've had a lot of questions on on it and remember if
you're going to type it in on Google to say the right were scary fire a CA are I fi er something
like that anyway we thank you for watching and as usual we'll see you guys on the next one by
