Im finishing my basement and started the drywall taping and spackling last night. I bought a book on it, and the book says after you tape the seems, let it dry before applying another coat. Ive read on the internet that after you tape the seems, go back right away an apply a thin coat. I didnt do this, I went with letting it dry overnight and I will apply another coat tonight...will this mean I have to add 4 coats to my taped seems, or can my 2nd coat be the coat to cover the tape. Thanks for all the help.
