Installing Tyvek Weather Barrier House Wrap: How To Build A Shed ep 12

in this video I'm gonna show you how I
installed a vapor barrier all around my
shed now some folks call these air
barriers or moisture barriers it's just
a barrier that keeps water from getting
in as well as keeping air from getting
in from strong winds but it allows the
structure to breathe I'm using the
product from DuPont called Tyvek I
bought this and paid for it myself I'm
not sponsored in any way this just
happened to be the right size for what I
needed at my local Home Depot I think
this roll was about three feet or so
tall and it came with more than enough
length on it to do the entire shed for
fastening it I decided to use the same
nails I was going to use for the roofing
felt a lot of people prefer to use
staples when attaching this I went with
these nails because I wouldn't have to
put in quite as many and I already add
them so we're going with these before I
got started with the wrap I needed to
cut out the threshold on the gable ends
and you may have seen in my previous
video about framing these gable ends
that I did a little trick when I built
these walls in the first place before I
stood up these walls I cut halfway
through them from the underside which
was gonna make it really easy to cut
through from the top after it was all
stood up and I was at the stage it was
time to cut out the threshold and I did
this because I didn't want the saw to
come down and scratch up my finish on my
concrete and dull my saw blade so that
made cutting this out really easy you
can see I only had to go about half way
through and then this threshold came
right out so with the threshold cut out
it was time to measure up and mark the
wall where I wanted the top of the wrap
to be installed and I wanted to make
sure that the wrap would overlap down
beyond the bottom of the wall by about
an inch so I marked it so that it would
do that so that any water that gets in
on the wrap would come down below the
wood and just come run down the concrete
foundation then I used my level to
transfer that mark all the way down the
wall and then just stretched out the
wrap and met it up with that marking and
nailed it in the process is really
pretty straightforward the the one thing
you want to do if you are gonna nail it
is you want to make sure you're hitting
studs with those nail
when I installed my sheathing I was
careful to make sure that the lines that
are already on the sheathing lined up
with the studs inside the walls and so
it was pretty easy because my walls were
already marked if if yours aren't that
way of course you can snap a chalk line
or mark them before you do it so then it
was just a matter of working my way all
the way around and installing the
sheathing just nailing it in about every
16 or so inches on every stud alright so
I finished with the lowest course of my
house wrap and now I'm ready to put it
on the next one the problem is I'm
working alone and trying to hold this
and unroll it and hold that up and wrap
it around and find things and hammer and
nail it there's just too much I don't
have enough hands so if you're working
alone I've got this neat trick I want to
show you that makes installing house
wrap really really easy and it involves
this painters pole and a clamp let me
show you this painters pole is one of
those extendable kinds you twist this
end and it gets longer if you happen to
have one of these laying around already
they're great for this if you don't you
could use a piece of PVC or even just a
broom handle anything that is gonna fit
inside the center roll of your wrap
slide that in like this now all you need
is to put a clamp right down here
that'll hold the wrap and approximately
the correct height and then you can roll
it out really easily and be able to nail
it in I'm just going to use one of these
quick clamps here so there you go it's
ready to start pulling out and this
clamp will be able to lean up against
the wall like this
and stay there while I'm busy nailing
things in once I'm finished with this
course the reason I really like these
extendable poles is because then to do
the next height all I have to do is lift
the pole up and extend this end lock it
down and now you're ready to do your top
course or your third course so let me
show you how easy it is to use this
thing so I'm going to measure down six
inches and I'm just gonna make a quick
little mark it doesn't have to be very
precise and I'm just gonna do this at
each of the corners all right so now
that I've got my Heights marked all I
need to do is adjust this clamp so that
the bottom of the wrap is more or less
right in line with that mark doesn't
have to be perfect
boy I'll tell you what having this
painter pole really really helped it was
almost like having another person there
to hold the wrap in about the right
place and as I worked my way down around
the walls it held up the wrap you know
close enough to the correct height that
it was really easy to stretch it and
pull it to exactly where it needed to be
and then it was just repeat the same
process I'd done on the first course at
the bottom and repeat that process all
the way up the wall
now I know that there are some of you
out there who are watching me install
this going why in the world is this guy
putting a vapor barrier on a shed well
the answer is because for now yes this
is just going to be a shed it's just
gonna store my stuff but at some point
in the future I might decide to turn it
into a workshop or into a man cave or to
some other functional kind of a building
where I might want to insulate the
interior walls run some power out to it
maybe install an air conditioner and at
that point it will be too late to put
any vapor barrier into the walls and
I'll really need it at that point
so I decided rather safe than sorry go
ahead and take the time and get that
installed now and then I don't have to
worry about it if I ever decide to use
this as something else all right so once
I had all of the walls wrapped it was
time to tape up the joints now DuPont
makes this specialized Tyvek tape that
matches really well with this wrap it
bonds very very tightly and it's stupid
expensive it was like 20 bucks a roll I
wasn't real thrilled about that but I
decided if I'm gonna do it I'm gonna do
it right so I went ahead and bought
tape now I did find that this tape
doesn't really like to unroll very well
at all so one trick I used that save me
a lot of frustration was when I was done
using the tape for a minute I would just
fold down one the end just a little bit
and that would give me a tab to pull on
later that made it really easy to start
again
the the next seam that I was going to
tape down so the only note that I have
for taping is to take your time and be
really careful because once this stuff
sticks it's like superglue it does not
want to come off and you want to try and
rub out any kind of creases or kind of
imperfections make it as smooth as you
possibly can
once I finished up the taping then I
just wanted to make sure the gable ends
were all covered up as well this is
mostly for driven rain ingress we do
occasionally get driven rain here and
driven rain for anyone who doesn't know
is rain that is blown hard enough that
it's basically raining sideways and so I
wanted to make sure that the gable ends
were recovered in case this you know
sighting had any cracks or leaks that
would let water in there's no real
tricks to this particular process just
hold it up there as best you can cut it
around the things that are already there
and nail it down around the edges and
then tape up all the seams when you're
completely finished so that was
basically it once I had all the seams
taped up then the shed is ready to start
installing trim and siding and that's
what I'm gonna cover in my next video

next video comes out and I hope you've
learned something if I did something
that was boneheaded completely wrong or
just plain stupid
by all means I'd love to hear about it
down in the comments I learned from you
hopefully more than you learned from me
so let me know if you find anything
there that I could improve on I'd sure
appreciate it
and as always thank you very much for
