  • Drywall Question

    Folks,
    I am removing an interior door and covering with drywall. Vertical seems between old and new drywall are both supported by 2 by 4 studs. Drywall installed with drywall screws. Mud, tape and more mud are applied.
    What can I do to prevent the eventual crack that may develop at this joint?
    Steve.

    Just use the paper tape and not the DIY'r fiberglass meshing tape. It shouldn't crack on you.

        I like to use the paper tape too, but with caveats. Make sure you put down a good bed of mud to push the tape into first. And I like to use Durabond 90 as my base coat and at least one of the two top coats. The Durabond has portland cement in it, so once that sets up in the paper tape it's just like concrete and won't crack. Knock it down and put a second coat of Durabond on top. Top coat (finish coat) can be one of your pre-mixed drywall muds that sands real nice and provides for a smooth, slick finish. Take your time and do a good job and you won't be disappointed. Many DIYers want to rush a drywall job and skip a coat or two or the sanding between coats and that's where they mess it up. Good luck.

            As others said make sure you use paper tape and embed it well in setting type compound. Too many times I've seen people use the mesh tape, and with standard mud at that, and it will crack...

              So is the fiberglass mesh just inferior to the tape or are there applications where it would be preferred?

                Maybe a patch job, from a small hole, possibly cracks in a plaster job. My experiences and jobs that people use this stuff on (normally a handymans job), garbage. Why take a chance, paper is more superior.

                I once had to patch up about a 100 cracks in a house that was all plaster, there was blasting going on, for a new tunnel 2 miles away. This blasting caused the cracks. Anyhow, I did use fiber meshing and never got a call back. But to do seams, nope I'll stay to paper.

                  Fibreglass mesh tape is needed for wet installations, such as on tile backer in a shower.

                  Hmm... why do I know this?

                    If your framing is tight and secure, you should not have problem with cracks regardless of what tape you use, what causes cracks is movement and shifting, and if it moves it will crack more than likely.

                    I do not like working with the mesh tape, but in some instances it is better, I think one gets a better finish with the paper tape, both will tear or crack if the framing or drywall moves behind it, it is the weakest point, of the wall, (I have done a lot of dry walling but not a dry Waller),

                    and I am not sure the mesh tape recommended for the cement board is the same that is used on dry wall, may be some one can enlighten me,

                    the cement board should use alkali-resistant fiberglass mesh tape, http://www.hardwareandtools.com/invt/6307748?ref=gbase

                    Long-lasting, vinyl coated strands will withstand corrosive effects of the alkaline present in cement board joint finishing, lightweight concrete panel seaming and crack repair, block foundation, and reinforcement for fiber cement, and concrete stucco. He avier fiberglass yarns for more strength than regular mesh tapes.
