Using tape on a ceiling drywall repair
 
I have a 14" x 16" hole in a ceiling (removed for leak repair from upstairs) I need to repair. I plan to install a new piece of drywall that will be cut to fit. My question is this: Since the ceiling has a stomped finish, which I will try to duplicate, can I get a good result by simply mudding over the joints, without using tape, before I apply the stomped finish? In other words, will just mudding, sanding, feathering, etc. before stomping work OK? It seems to me the stomping process will cover any slight irregularities. Or am I missing something essential about the taping step? Thanks.

take a orbital sander to the edge of the cut out(80 grit)sand away the edge 6" out to get rid of the texture.fit the new piece in place,better to be set a little deep.take a bag of hot mud,40 min or 20 min.mix this in your mud pan,add water with a sponge slowly until you have a thick pancake mix.you must tape the joint so it will not crack later on.use yellow mesh tape.sand between coats or scrape down with drywall knife.use the same mix for texture,practice first on a scrap of drywall.prime and paint.

When mudding a seam, it is essential to use tape to avoid the seam from constant cracking. Mud shrinks as it dries and if applied too heavily initially will crack no matter tape or not. One rationale is that tape helps hold the mud into the joints.

Thanks. Now that I know why tape is used, I'll use it!

Done!
 
I mudded and then taped with the yellow mesh tape (tape still showed); let dry for a day; mudded again to cover the tape; let dry for a day; then sanded and feathered and applied the texture with a round texturing brush I got at Lowe's. Dang near a perfect texture match! I've watched it done a time or two, but this was the first time I did it all myself, and I'm well pleased with the result. Now I'll just wait and see if any cracks develop. Thanks for the good advice!

Good on you,
the thing about using hot mud is,it shrinks very little and drys very fast=no waitng aday per coat.
