I'm working on my first drywall project. I used paper tape for the
joints. I think I followed the directions, essentially I spread on
a layer of jointing compound, put the tape over that, spread on
another layer of compound, let it dry, did another coat, let it dry,
did another coat, all done.
But then I started sanding yesterday, and for several of the joints
I started sanding into the paper tape before the joint was flat.
So I think for at least some of the joints, my first layer of
compound was too thick, and now the tape isn't far enough below
the joint surface. Is there a way to fix this? Can I sand out the
joint and re-tape it, or is it so bad that I need to tear down and
Thanks for your time,
Spread your first layer of compound, put on the tape, add a little more
compound on top, and here is the key: press the tape firmly as you go
over it with a taping knife. When you press firmly, you will press out
a lot of the mud from underneath the tape so that it should sink down
into the bevel (assuming you are taping the beveled edges, and not butt
joints). But don't press too firmly, or else you will force out all the
compound from underneath the tape, and that's no good either.
Secondly, if you find that you are sanding down to the paper tape, stop
before you sand that deep. If you don't get the tape down into the
bevel for some reason, or if this is a butt joint, then the tape will
just sit a little higher and you will need to feather out the joint
over a longer distance with more coats of compound. Even if you do
everything perfectly, you should still have three coats of compound.
I patch a lot of cracked plaster and add tape over cracks that are
bowing outward from the wall slightly. I have feathered joints out to
1.5 - 2 feet wide with 4 or 5 coats of mud in extreme cases, and those
joints pass the light-against-the-wall test.
Ahh memories... Just about forgot the first time that I did
my first tape and mud job....
Reason why I forgot it was because using paper tape was a nightmare
that I would like to forget. I know I know, some people love it, I
personally loath it.
Fiberglass mesh tape was the way to go for me.
Its somewhat sticky (so you can first tape up a whole room at once)
then you go around and use your favorite joint compound.
Seams look great (cant find them) and I havent had a crack yet (hey its
only a few years now)
Do yourself a favor and buy a small role of this stuff (its next to the
conventional paper tape) and give it a shot.

just remud it, taper it off each side, then LIGHTLY sand it. there is a
tendency to oversand when you first start mudding.
the wall will never be billiard table flat.
in the future, press harder when you mud. you should see mud squirting out
from under the tape. dont be fooled by fiberglass tape. it has its own
issues, and is particularly bad when used for inside corners.
if you hold a light near the wall, you can easily see all the little places
you didnt quite sand flat.
hold the light in one hand, and a sanding sponge with light grit in the
other and go over the whole wall.
i never said you cant use the fiber tape... it saves you exactly one step.
you dont have to put mud down first.
but its thicker than paper tape so its a little more tricky to get it to
taper cleanly without exposing the tape, not the end of the world, just
something to remember when you are sanding.
and the paper tape is basically free since you already bought it to do the
corners. last time i checked it was about 6 bucks for a small roll of fiber
tape, and about a buck and a half for a huge roll of paper tape. if you can
do a corner with paper tape, a flat should be a no brainer.
both will last equally long if applied properly. both will look equally
good of applied properly.
use whatever floats your boat...
my point is simply that some people think this magic fiber tape will take
all the work out of the job. it doesnt. it saves one small step.
Another stupid moron trying to compete over his level. How about rip it
off and call a professional or start smearing thick coats of mud on top
of it, and call it stucco. Whoops you'll probably screw that up too.
Hope you tackle an electrical job soon so we can read about you in the
Obviously an angry contractor with no customers.
(gee wonder why!!!)
I dont understand. Just let the guy give it a try.
If he (or she) screws it up, then they call someone in.
To a contractor, whats the difference??
Just rip the shit out and start over.
You'd make the same one way or another.
Its almost like these guys get all upset because someone
gives something a try. Ok I understand that if a guy
is clueless about electric and tried to upgrade his service
on his own house, thats a real saftey issue. But
complaining about someone doing a little drywall work??
Its harmless and can be rewarding if it coues out right.

Heh, heh, yeah, I can't completely disagree with that sentiment.
There've been quite a number of times where I've wondered if
doing the job myself is one of the dumber choices I've made or not.
Overall, it's the right choice for me because of two reasons:
1) I like to do this kind of stuff. If I get it wrong, I'll do it
again, and chances are I'll do it right. I'm a fairly capable person,
and I enjoy the goods and the bads. And really, none of the stuff
has been all that complicated.
2) I've been kind of disappointed with the results I've seen from
*most* of the professionals. A lot of them didn't care, didn't know
what they were doing any better than I do, or just sucked. A lot of
times you get charged too much, the job takes way longer than it's
supposed to, and the results are crap.
So, for me, doing it myself is the way to go. Whether you agree or
not really has no significance, but, like I said, I don't completely
disagree with what you're saying.
Thanks for sharing, take care,

Too true. Actually, it can be worse. The mastic holding the threads
together can fail during the initial coat and can leave threads
popping up at the ends. I use mesh tape for repairing plaster cracks,
where I want a little more bonding strength but rarely on drywall.
Actually, I ran out of paper tape on a renovation job I'm doing and
used mesh tape on the remaining drywall. It worked well but I also
used a 16" squegee(sp?) to lay the second (final) coat so it was wall
Mesh tape is avoided by most pros as it needs 'perfectly' clean surfaces to
adhere and not much drywall mud goes into clinical labs.
Use paper tape and a fast setting compound mixed @50% with standard
compound. Usually a durabond 90 mixed with mud gives best results with
wetted paper tape.
