What size knife?
What size knife do you all put your last coat of mud on with on qrywall joints? What about corners? Also, how wide does the topping compound being on say a tapered to tapaered joint, or a non-tapered-to-tapered joint?

Tapered joints-12"

Butts--16 to 24" ( depends on what it takes to make the seam vanish.)

Mo, As Mike said 6" & 12" should also work for you.
The more experience that you get along with more tools the more sizes you will use, but a 6" & 12" will get the job done.

I recommend Myron's book on drywall. It will more than pay for itself an your first job.

Thanks guys! I put the last coat on the walls last night. It turned out a lot better than my other garage I did last year. I don't think I'll have to do much sanding on this one. One more question-

It took 4 1/2 boxes of mud to complete the 2 car garage (22' x 23'). That seems like a lot to me. Does that seem normal to you folks? It was taped when I moved in. All I did was smooth everything out for painting.

Seems like a bit much, but if you're happy with the results....mud's relatively inexpensive.
