okay while back we did a paint know Cody's video industrial coatings video
we had an industrial coatings expert in here that talked about that if you want
to go back and see that video first because the cool thing is he's back and
he brought his equipment so meet Erik Montague professional coatings inspector
Wow oh god I have a painted boat sitting out there it's this tense alright
because it's like you know I could slap paint on this like let's go and it's
like but now we're gonna test that shit out there I think well we'll see if I
did a good job we'll find something positive to say we
better find the truth because it's better easier paint here than it is in
the oceans it's the first thing we do calibrate the equipment yeah so
calibration you have these little standards known standards and their
thicknesses of plastic at various thicknesses of course and we've set up
for the middle one the middle ones 38.4 billions start off by collaborating to
something that you think just gonna in the right range so you get yeah yeah
more accurate yep so I've done that Mme do I get to make a guess about what I
think it is all right let me think that's it that's how you do it's pretty
anti-climatic is it does it just like yeah how's it a verge the readings it
can you just check it each one alright alright so here let's start back here no
I'll call them out is whatever you okay yeah 28 I like that 29 for you know it's
not a really smooth surface so does it read from the paint or does it read it
from the tip it's touching so that transducer has a point so it's
based on that diameter so yeah it's and then okay so within that area okay from
that dress is a point so a little flux a little wave or bump in the paint try and
make it in difference right so that's twenty five six
so the SBC says that for each area you test there needs to be three tests
within an inch and a half area right seen you average those three for a
reading and and it's five areas for every ten square
meters I think it is right you know I'm not actually a coding tester I'm usually
the guy that comes in when there's a coding failure yeah and I'm usually
looking at the steel behind it all right so so it's so I play with this kind of
stuff but I mean there are guys that are nice coding guys where all they deal
with is just Cody right and I mean those guys those guys are bluebird coding
those nice guys tell me you're an amateur geek Cody yeah I can introduce
you to these nice level three guys in Blau all right yeah well let's go around
there's a few more just see how then we actually go here's an interesting thing
so that's that's a reading of 23.5 at that spot right if I move over the
diameter of the transducer yeah twenty four six okay and move again
twenty four zero now that I shot twice because it's a
well for doing seven three I know I expect that because I came over here and
I shot the welds all separate just to make sure so thirty nine eight yeah it's
down low or thirty nine thirty five thirty one twenty six okay twenty-eight
what do you think I I love it you've got a fairly uniform coating
that's the sprayer I don't think with roller woody we know we all go up and
see what the roller do twenty-nine let's do that smart I kept reaching over in
right there forty two thirty three thirty three
thirty eight forty forty forty-one you know what we did we sprayed it again
forty eight you know we sprayed it again after we rolled it twice so we're done
so it's just definitely has enough your fun yeah and I still don't think because
you did because it's so sick you have to worry about it that should be a lot
thinner there so let's see you yet we got the six four six mils maybe from the
safe for from the zinc primer okay and then I got now right up against the edge
I paint twice cuz it are you guys strike good right so we need that it'll be
thinner out here and I think I got this is amber lock - I think I got six to
eight so I got at least ten eight pack seven seven alright that's kind of thin
for me nine nine
ten-nine now remember i calibrated at 38 so this measurements probably off
because i'm but it's cause it's close yeah probably thicker than that i would
i would i would guess that it's tennis when i guess over your honor we're a
little under 10 so just looking at it I would say the trotting along the side I
think Italy particularly that little closer to that bite and see are you
saying six and eight seven six and a half okay
I maybe I didn't go there Oh twelve well I'm okay but I'm spraying
underneath that pipe from both sides right so in 1294 okay
eight eight so that little just looking at it done yeah it's not filling in I
would say that's probably pretty close less than 15 mils just looking at all
right which that's what it's telling us so I believe it well that call it
doesn't build up like that coal-tar does that stuff goes make the coal-tar they
say you put it on up to 20 mils thick in one pass in one pass yeah and I didn't
reform layers yeah you get a lot of pain you know they make some of those
products they called them high builds oh that is it is cult rh b that HBA high
bill they have some products out there with
it that are designed for the maritime industry yeah where they're actually
they were actually D formulated for spraying on the prop in high build
application saying build it up almost a quarter inch thick so they can go back
while it's still soft and profile literally flat fare the prop but it's a
paint that's designed to go on that heavy heavy 100% solids but with it if
you put a paint on that's not designed to go that thick
oh yeah just come on how does it come off is it cracker does it it doesn't it
doesn't it doesn't when they when they when they beach those boats in India or
wherever else they're gonna break those ships that coatings still on there okay
no my question here is what if we what if you take a paint like a Murloc to and
you put it on too heavy what's it going to do well sooner or later it would have
a har time staying bonded so really it doesn't
crack adjust let's go the subsurface no that's what we do is it would hurt it
would become so it was it would become so thick its inflexible and then as the
base metal flexes it would either crack or it would pop off it depends on both
the substrate and the coating okay so instance I had a place where the
boat hull flexes it'd be important not to have it too thick right right and
that's so your your so your hole is built with quarter-inch thick plate yeah
you know but it depends on some of the other things like where is it gonna hit
the waves and how this has that plate gonna boil I can show you some examples
from last week where the floor is a quarter-inch carbon steel just like the
hole of your boat right and the floor of this tank was supported in between IVs
the floor deformed in between betwixt the supports yeah and the coating flexed
with it and did not crack okay I would expect that from any industrial coating
but I can also show you an example in the same situation where the coating was
so thin it did crack and then because it had a path to the steel got behind it
it got behind it and super accelerated corrosion so it doesn't matter too thick
to thin you want to avoid both of them correct
both are evils right I need to go look at my amat marelok and see what there's
a huge range and remember that's what they're willing to stand behind it
usually will operate way outside ice that's what they're guaranteeing
right you know what it can do is fact you know areas below and above that
range remember if they understand that this stuff has to tolerate the average
person applying it the with the average effort that's us yeah
well we're average we'd like to say that well or we hope our average I can tell
you from experience you guys are way above average that's that's scary
we don't do this for a living well what's scary is the kind of effort I see
with people who do yeah you have an example of that for us don't you I do I
have some in our society we we tend to refer to things as porn where where it's
sensational and in the inspection business we call it inspection board
where it's so cool and so neat to look at that it's porn for us inspector and
I've known in the industry as having all kinds of examples of geeky inspection
failures that's you yeah that's me will it work on the nonskid I mean we've
got a good metal follow after gonna say 60 I would say north of 65 maybe 100
well that's some of the rough 94 yeah good guess 88-78
as he finds such thin spots 48 yeah that makes sense when you get down in the
Bally's 63-62 let's see if I'm gonna 103 yeah the flatted areas yeah we always
put it on like that you know trout on knock down stucco and
what's cool about this stuff is this stuff is designed to flex so much
it'll never pop off well that's good to hear it yeah as long as there's not an
incompatibility between the three layers of coatings you never know a PPG made
sure and single source made sure that the bat abilities are right yeah that's
what they're willing to stand behind these beautiful tolerate extremes beyond
that that's just what they're willing to support you know it's even done real
well in our wood and gangplank I don't think they say anywhere use designed for
that but it has such a good adhesion quality that yeah and until there's oil
behind the wood or the wood itself starts to fail well they're never gonna
loose I think it's water that gets and soaks up and gets behind it some type of
intrusion yeah yeah yep whether it's water oil well we didn't even work on
the end so it's actually at the word the board's cut and I didn't do anything for
the end of the board so yes not you're gonna find stuff like this actually gets
worn off where you've got cables and chains actually wearing yeah grooves in
this yeah well that's just where it turns like that's not gonna happen up
here I mean it'll happen up there on the fort but back in here kind of product if
it wasn't so expensive would be nice to put along the side where you're gonna be
throwing a chain or some other piece of equipment that's the idea that well I'm
answered a really expensive rub guard well now if you use you know in small
areas right and another problem is is this is the color some you can paint on
top of it but I'm not gonna get to yeah we're not that boat you know
people ask me are you gonna paint the pilot house back there you've got wood
and moving having a tree you're almost that boat yeah yes true we get in
between those two places running betwixt a lot if you think we're like a fishing
boat you're going a fishing boat I've been on those fish yes if they have
paneling on the wall I mean what supply wood it's pretty classy yeah well it
should be about ten to seven seven okay six for who five - Oh 11 I'm up against
the it was a bugger I'd died there no but remember I still calibrated at 30 so
going this thin it's gonna have an error you know what the deal is I I sprayed
the zinc on with a air gun and so I know that went on then 25 in this direct coat
yeah 25 25 1 I'm glad dick went around the world because that's the part that
seems to rust in it well so what I find in the industry is
anywhere there's a rough surface so a weld a transition a shape change those
are always areas that that flex differently than the rest of an object
and because of that if there's going to be a failure it's
either going to be right next to there or in there either because it's too
stiff or it's because it's flexing right at the edge before it gets to that
transition I've got plenty of photographs in tanks where you know the
weld is rigid up against the shell and floor but where the floor is moving
right there where the bending moment happens it cracks the coating and when
there's a failure in that bond yeah that's where the corrosion happens it
makes a lot of sense yeah any time there's an intrusion that's you know
that's where your corrosion is going that makes sense because these panels
flex but it's gonna be stiff right there where the braces are right and it's just
a matter of I mean you know the the kind of distortion I'm talking about we're
talking about deflections of you know half an inch world we've hit a big wave
to get a half inch deflection yeah if you get that kind of deflection you've
got other problems first the neat thing about this kind of coating is this kind
of coating you know you can you can put a you know one of those scotch-brite or
sand pads on a grinder knock that area down you know get some teeth blend it
back so that there's a nice transition between the edge instead of a broken
edge of a coating where it cracked or popped off you blend that back to like a
five to one ten to one transition has nice tooth so if you're doing a repair
you want to feather the side of that repair area yes and you want to feather
it as much as you can tolerate how do you mean by that so I can show you
examples of where coating has failed and there's literally a step invisible step
in the coating you know 20 mil 30 mil step in the coating between the the
existing coating and the repair air that needs to be made so you want to see a
couple inches yeah and the more the better I mean there's a point of
diminishing return but you know industry-standard free transition is
like three to one or five to one so you figure on a coating you'd want double or
triple of that but you know 15 in one transition ratio we're still talking
about less than an inch of transition area
you know so yeah you say half an inch to an inch of transition to feather that
back but still going to give you a nice enough area to to feather that back and
still have an adequate adhesion zone you know you hit that with a tiger paw or
some other type of sanding pad and then wipe it with some you know as long as
you're not California mu K or some other nice degreaser get it nice and clean get
all the dust off and then reapply it well you made a real strong point about
that degreasing thing to when you're here the first time yeah well those vis
you made a real strong point detail is your worst enemy I can show you some
examples of tank I've seen recently where they cleaned it real well probably
you know beyond what I needed to inspect but it's still not cleaned it's still
not degreased to the point where I would feel comfortable for a recoat right and
that's especially in oil and gas you know in a boat you're just trying to get
it salt free and dry but then they also need to get it
degreased well the thing to me that's something I hadn't heard before was all
the oil that the air compressor uses yeah so in your engine room anywhere you
know anywhere there's gonna be all used so your engine room anywhere there's
gonna be an oil compressor somewhere where you change the oil on a welding
machine right that's you know any anytime there's oil on a coating you
know I mean they have different levels of permeability you know how much can
the oil soak in a rest assured there's always going to be some permeability and
a lot of times when people try to remove that all they're doing is smearing it
you're contaminating more area and if you're talking about a braiding it you
know with sandblasting now you're talking about impingement so you take
your thing is remove the oils first you you anything before you do the
feathering work that you're going right and if that means you you need to use a
degreaser either a camel or or caustic based degreaser get that
grease cut get it you know get it get all the debris removed then cut that oil
with something you know I mean m EK works wonderful but it's a horrible
substance to carry yeah there's other stuff acetone
acetone works a stones are pretty pretty middle-of-the-road results caustics work
you know compliments there's lots of degreasers out there market I mean even
simple green or that or that inviting any degreasing solution will work I mean
it doesn't need to be industrial-strength but I mean soap and
water will do it given enough time and effort it works off magnetics so yeah so
you've got a known standard and basically it doesn't work on wood if it
works on magnetics it has to it can work on fares and I don't know if this won't
work on volunteers some of them Wilson I mean they've got some neat testers
this is actually an old quite an older model right and most of them now or
don't even have detachable probes it's all built into one little thing they've
got you know really for your phone for it to the new ones new it'll auto
generate your report so a nice a lot of these standards you know you need to
take a minimum of three readings in any one area and then a minimum of five area
five sets of readings in an area to be an adequate inspection so a lot of times
it'll also prompt you you need another reading really I mean you need another
set of readings and then okay there's also for the SPCC the reading is allowed
to be 20% under and 20% over if you get readings that are outside those areas
you need to do additional inspection and then you need to isolate the area that's
that's either too thin or too thick and and the new ones will prompt you in all
of that they're pretty fancy this is almost thin paint anywhere this is the
thin spots if I got any in here cuz this is no primer this is just air marelok to
sprayed on generic sprayer of one coat so I'm thinking if I got three I'm happy
turnip rope around 910 Jesus 1112 okay right can I use it
I'm just new track just push push to a flat contact and that's all you got you
got to do there's not a button on the bear not a button that I put on there
five four three yeah see six okay so I'm okay
six-two so what I like is the places that are thin are the places I knew were
thin well it reinforces I already knew what I already knew yes so it feels does
feel better knowing this machine knows what I know
yeah or empirical to quantitative yes it's nice to stepping from what you
imagine is right - what it's proven right a lot of my business is proving
what I already know yeah you can show us that - I can't
that one's even even more intuitive and less or the next gadget yeah the next
gadget so what do you call it when you sit when you say somebody go to the
truck what do you tell him to go get the mlo gauge ml Oh tell me again with that
stance or coding tester this is an example of repair we could done better
you know because I got this you can see the edge we didn't feather it before we
painted it again you did this I did this we can burn my
paint off I did remember we put these angle irons yeah he's built back a wall
the debt yeah so yeah I burnt that I personally burnt that sombitch but the
neat thing about it is notice we don't have any air bubbles or solvent you
think yeah so you think this example you saw the other day was solvent was used
to clean it and it got underneath the paint cuz they didn't take off all the
paint they was to do this the next time if I owned though I can sand that down a
couple inches out feather didn't real nice before I shoot it the neat thing
about this Doug is we can actually Holliday test this area okay see you see
if I screwed it up well to see if there are any voids that go all the way to the
pigs basement yeah the bristles from the brush coming off and creating a wig
right we talked about that and I made the comment that the chances of those
two holes that were lining up right yeah that's not a demon isn't right yeah I've
had guys chat me about that that no that's that's a very real
possibility it's only a possibility if the coating is put on any single layer
right no coating manufacturer says put on just one coat right there are some
that are designed to do it all in one coat but everyone realizes one coat over
bare metal means any defect go straight to metal which means if you put it on or
two or three layers so on this boat you've got a galvanized layer hmm that
you've got you know I mean here it's it's coal tar coal tar well no you had
the surface prep before that well is it rest doc yeah yes there's no converter
so you have the rest converter yeah and then you've got the coal tar so
now your so now we're talking about three layers right so no no no primary
oh no prime that's right this is so sure it's just rust doctor and then the
culture yeah and so what works so that's two layers
yeah on the outside of the boat no it is a lot more than this so did you have the
restauranteur on it no we didn't use russet or anything but you think they're
only blasted right so you so you have a so you have a sandblast and then we have
a galvanized primer well let's go through the steps though so you
sandblast sandblast yeah then you rinsed and then we decreased and we rinsed
again and then you rinsed again we might have used with high yeah if cut the
flashlight there's four steps already yeah and then you've got a zinc
galvanized coating yeah and then you'd leave one and then you've got a base
coat where we got the impermeable coat which have been the hammerlock oh so you
put an a Murloc on yeah and then you put on then we put on coal tar and that's
you know that's a step up yeah and and then we'll put on one more coal tar and
then we'll put on our anti foul yeah so we got two more custom think that's an
entire system right yeah and that means even if you did have an individual
holiday in any of those coats they still have to have a holiday in the
that's on top of that one for it to fail all the way to basement right so sure of
running into a floating container right or which will do well we get on patches
well that's the neat thing about this process is you know you've got a flat a
flat bottom kill you find a nice shallow s'more with enough swing in the tide
right you swing out you you wash it off so your salt free let it dry or force it
to dry take a portable grinder or or or even a hand file a braid that surface
back to a decent profile something that doesn't have a transition that's that's
so abrupt right mix up a coating to patch it up patch that area force it to
dry or let it to dry naturally depending on what you have time for yeah you know
most of these coatings are designed to be forced to York the post here a lot of
times they're called this what we're doing in the back
kevin:today we got that heater back there it makes them paint go off yeah
most of our designs so that if you get them above 110 120 degrees they
accelerate the cure yeah so and most of them will tolerate
uh they say on the label they like ninety most the time oh it varies from
from from coding to coding but the idea is they all have a post cure a
recommendation right so you can force something to cure real fast if the tides
coming in pull out a weed burner or you know maybe a hot air blower yeah and
they're young you know make it skin over well enough that it's dry before it gets
wet right it'll still be inadequate repair cool hey talk to me about this I
got these pipes down there what do you guys do you wrap them
so this is just steel all right it's just steel and and this one here is
gonna move yeah and it's gonna braid well in the code I'm planning on heating
it here and bending it and bending it up to get it off the floor right there this
is touching the floor it needs a spacer or an isolator and I can do that
slip a piece of plastic underneath yeah that's no problem yeah cutting board um
they need to be coated with something yeah I know it's kind of a question in
prep just some little you can't sandblast much in there so in industrial
situations a lot of times what they'll do is they will take a pad of scotch
brite yeah and then rough up the surface with scotch brite and then apply a
coating with either a brush or one of those really small diameter rollers okay
in the industry they use those for pipe a lot okay well we can do that
yes appreciate that's that's a and and and something I would want to pay
particular attention to is I want to see some type of anti corrosion in our
corrosion inhibitor right here at the threads because that is them that's the
part we're gonna worry about most and because it's cut threads you've got all
the kind of corrosion inhibitor you think about um like a regular like the
rust doctor type thing no I was thinking something low-tech like grease Oh
so paying first and then come back and hit those choices and grease yeah yeah
something nice and thick that'll stay there yeah even in the tropic heat it
won't melt off oh yeah well um you know the stuff that's on there is not bad
it's that pipe dope you know you know pipe dotes great but it's not it's not
consistent and it's not thick okay you know in the old days they used to use
like guitar a Vaseline type product was real common they even made some products
that were designed to be painted over top of all find something to keep an eye
on that yeah a lot of times in in tanks a threaded
hole for like a telltale hole they'll fill full of grease in the old days they
used to use axle grease now they just you know pump it full with a with a with
a grease gun and then paint over top of it and what's hilarious is a lot of
times the coating will bridge that spot and coat it over word yep a lot of times
I'll also see an earplug someone will pick up a disposable ear plug and stick
it in the hole let it expand and then just paint over the foam ear plug so
when I come through it and inspect it I don't disturb it because I don't want to
crack the code right so I'll just leave it but a lot of people you know they'll
pull it out oh yeah that's that's a bad thing you know actually it's it's a an
expandable plug that has now been encapsulated in a coating and when you
say it like that it doesn't sound so bad
