drywall ceiling panel electric radiant heat taped joint splitting
33 years ago I built a house and installed Gold Bond 5/8" panel electric heated ceiling. The system has worked fine. One large room I have a minor small section of ceiling that about a 4' section of joint that fails and caused a small ceiling split at the side or tapered / bound edge of the drywall panel. The tape is holding but just cracks through in the middle between panels.
I have repaired this joint several times but it just splits again in a couple of years. i will say that I always have used the all purpose pre mixed joint compound and alternated between mesh and paper tape. But it makes no difference.
Does anybody have a solution to this annoying problem? I suspect it splits due to he large area of drywall and the fact that heat is produced from this ceiling surface.

I believe the nails are holding but maybe i should throw one or two extra screws when I refinish this time. You mentioned Dura Bond. Yesterday I just happened to buy a bag of ProSet 90 lite in an 18 lb bag to be mixed. I do recall when I ordered that Panel Electric reading the associated literature and they called for a taping compound of Sta Smooth 90 to embed tape. I could never find any of the stuff. They might not even make it these days unless they changed the name to the DuraBond you recommend, Mark. It is supposed to be stronger than regular joint compound and is of the quick set variety. Thanks for checking in checking and I will look for and try durabond.

Be very careful putting screws in. If you nick a wire you are in the cold.
Sta Smooth is a brand of setting material. There are other brands. ProSet is another brand. The 90 refers to the set time in minutes and it is pretty close to real life. If the area is small you can use a quicker set mud but since you have it already use the 90. It gets harder than ordinary joint mud but not as hard as DuraBond. If you use DuraBond make sure you have it perfect before it sets for it will wear you out sanding it.
I still like paper tape even with quick set mud. A trick is to wet the tape before you embed it in the mud. Don't wipe it so hard that you squeeze all the mud out from under the tape. You need that to hold the tape.
Let us know how it goes.

ceiling radiant heat
I have a 12 unit apartment building with radiant ceiling heat and I've had splits in every unit. What seems to work best for me to first remove the tape along the split and any loose ceiling paint and compound and get it scrapped to the panel, if possible. Then I use drywall screws to make sure it's secured to the joists properly. I then prime the surface area to be repaired and let it dry. This allows the compound to adhere to something. Then I use paper tape and compound (tub or quick dry - it doesn't matter) to repair the split. If the ceiling is textured, you can texture it once it drys. If it's textured, I use a textured roller to further the repair and blend in the area. And that appears to be holding for the last four years, so far.
