Sanding drywall primer and a few crack repairs
Just finished priming my walls with Sherwin Williams primer. 95% of everything is good although a few fiberglass seams showed up and cracked in the hallway where there is no airflow and there are a few spots around where I dripped primer.
1) What should I do with the fiberglass cracks? I know the use of this tape is highly debatable but I did use it and I just need to repair a few seams only a few feet long. Should I just sand down the cracked seam and recoat on top or should I cut out the tape and redo the seam with paper tape?
2) Can I use 150grit drywall paper to sand the primer drips?
