    The US Gypsum drywall manual says to use paper tape with pre-mixed mud and to only use mesh tape with "setting" compound. I.e., compound mixed from powder.

    The fibreglass tape doesn't work because it keeps the knife from forcing the mud into the paper on the drywall, so it doesn't stick. Also most diy types don't thin the mud enough when taping. No idea on OT and sorry for adding to tangent.

    Not to completely derail things, but they sell the fiberglass tape around here as a DIY alternative to paper tape because it's supposedly easier to apply or some such nonsense. Consequently, the failures may have more to do with "operator error" but I see fiberglass mesh tape joints fail WAY more often than paper tape and it often delaminates as Georgineer described. Maybe that's because the DIY folk are using some crappy, slow mud or something, but I won't use the mesh tape for drywall.

    Try polypropylene chicken wire. Maybe it can do the trick

    Thanks. I came across this as well but I need something with a 1/2" to 1" size. Something like in the photo. This is an HVAC filter.

    started a topic OT-"laid scrim"

    OT-"laid scrim"

    I am trying to find a way to purchase laid Scrim. This material is generally either fiberglass or polypropylene according to the googling I've done. This material is used to reinforce things like hvac filters and cement underlay board. I've found that purchasing just the scrim is difficult at best. Any ideas?
