I need help with taping and mudding corners, particularly insode corners. Do i need a corner knife? i am having trouble figuring out how to get each side smooth on the run without screwing up the other side.

Thanks in advance for any replies.

Non-pro here.

A corner knife is great. I've never used a nice one, but even a cheap one makes the job a lot easier.

HOWEVER, you can lay a really heavy coat of mud with one.

With a straight knife, do one side of each corner all around the room. Then go around the room to carefully scrape off any deposit on the other side of the corner. The next night, to the other side of each corner.

Wall boarding is great for a home-owner to do after work during the week, because you don't have to rush and work around soft compound.

I've never used a corner trowel/knife but there are those who like them. Using a regular 3"-5" knife works fine for the intial corner taping - no problems with wet mud on each side. It is a simple matter to finish one side at a time, allowing it time to dry.
