Repairing cracked drywall seams
I've never done it and I don't see why it would help in any way. There is a "self adhesive" type of paper tape and I believe you wet it before applying, I guess to activate the adhesive(??). With regular tape you just apply a coat of mud, embed your tape by applying light pressure with your knife, cut the tape at the end of the joint, then wipe the excess mud out from underneath with heavier pressure. Allow to dry thoroughly before re-coating.
