Industrial Coatings Inspector with Dry Film Meter


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

  1. Hey Doug, You mentioned possibly cleaning around and under those pipes below the flooring… was thinking you could make an inside out belt sander arrangement for wrapping around the inaccessible bottom portions by taking a regular belt, then cutting it on a diagonal bias so it can be wrapped around the pipe in place with the grit facing inwards, and patch the seam with some wraps of duct tape, ALL the way around the belt. With that in place it can be turned by a drill chuck wrapped with tape, or if you have some sections of bicycle tire that fit the chuck snugly, that will give the belt traction to spin around the pipe freely…. Otherwise there's always long strips of crocus cloth/sandpaper by hand to clean it up…

  2. Thank you Doug and Eric for the very informative coating video. Never knew there was so much science behind corrosion prevention. Things have sure changed for slapping a coat of "paint" on something. Take care and have a good weekend.

  3. its good that the meter can test the paint as to pull all that stuff out of the engine room would suck if you had to do it twice….

  4. I love this guy he makes the thickness of paint seen as interesting as crash footage or other action that holds your interest

  5. Hey Doug, Cheers. Im always impressed by your motivation. Looking forward to the deck crane project too. Thanks

  6. I want to toss this into your coating mix. I worked for an off shore company that sold and repaired down hole tools. After the repairs they were cleaned and dried. We then dipped them into vats of WD-40 and hung them up to air dry. After the raw iron or other steel dried we would paint with paint. The tools would go out on jobs along the coast as well as offshore. This process kept them from rusting up and seizing up. You could get a few 25 gallons of WD-40 to go on your journey. If you see a rust spot or a nick just coat it. I was always surprised that WD-40 could be painted over.

  7. Speaking of de-greasers, straight Simple Green will dissolve roofing tar and will cut engine oil no problem. It is really safe enough to be used before sanitation in meat packing plants to cut animal fat off of concrete and equipment. I would recommend carrying a few gallons aboard ship for de-greasing and general cleaning without sanitizing since it is safe enough that you aren't going to have issues with bringing it into port somewhere and an inspector telling you it is illegal in that country.

  8. I need a new career where i enjoy it like this coatings guy. Granted BIG commercial concrete construction does excite me and is gratifying(plus get to "stand" places most ppl never see. Like 30 stories up hanging on a chain) but it also isnt consistent.

  9. Any paint applied to thick will not adhere to the surface. I've dealt with these paint mill experts for decades, in the end it is still a guessing game on the overall film thickness of a structure.

  10. On outboard motors we use this corrosion inhibitor. Spray on and leaves a nice film of grease.

  11. For pipe coating, grab a car wash glove and a dish wash glove. Put dish washing glove on, car wash glove on, dip in paint and paint pipe. This let's you wrap around the pipe with your hand and paint it quickly

  12. My 30 year old boar trailer that goes in salt water is in GREAT condition
    because the running gear has a hard grease coating.

  13. Paint is weird stuff, back in the sixties I was working for the army in the Marshall islands, the Sherwin Williams company had these little paint test stands facing the ocean with what seemed hundreds of different types of paint and it's amazing how many formulas for paint there are. Interesting good show Doug.

  14. I find it hard to believe the readings he's calling out a lot of the time. . . is it millimetres he's measuring in? Or a smaller measurement?

  15. Checking the thickness of the coating is imperative that the outcome doesn't lead to an explosion and a potential head trauma! 😘

  16. Holy Shit, this man is a wealth of information with coatings!   Love the video Doug!!!!   Thank You for sharing.   Matt C.

  17. Check out this we use it on large flange bolts in underground utilities http://northtowncompany.com/metalguard301.html

  18. Such a happy fellow, and never at a loss for words. Kind of in his own little world of specialization, with tons of related knowledge. Sometimes you have to wonder if being around the sealed surface chemicals too much, and for too long, might have an effect on one's mind. 😏

  19. take a piece of tig wire make a hoop with 45 bends on the ends you can slip it under your floor to lift it out super simple

  20. been watching this build for quite some time nothing more i enjoy than seeing a new video released when im home from work

  21. When the boss comes to inspect your work, you know you did your best but you're still shitting your pants. Tetrapotassium Pyrophosphate long story short.

  22. Thank God they didn’t put Eric in charge of musical plays – Industrially Coat your wagon just doesn’t have the same ring to it.

  23. 1 inch is 25.4 mm I have a hard time beliving that you have almost 1 inch of paint on the boat! But I have no experince of boats and coats! 🙂

  24. I love watching people talk about their work with passion. Easy and interesting to listen to even if i dont know two shits about paints / coatings.

  25. non skid is a stone cold bitch to get off if properly prepped. had to redo one of our breezeways in when I was in the Navy and fuck it was a pain in the ass.
