Moving a gas pipe in my apartment required cutting out long sections of the wall and ceiling. My Dad's friend did a quickie patch job, advising me to smooth down the rough spots with a wet sponge after it dried.
Is this correct? Shouldn't I be sanding it smooth instead?
I gently used a wet sponge on part of the ceiling and all it seemed to do was expose the tape he used... and the tape has bubbled out in spots, causing more worry. Will going over that with an additional layer of compound be the best course?
Thanks in advance for any advice to the newbie...
