In this video, I am repairing 2 of the cracked seams in the Drywall Ceiling. I use my knife to make an incision at either end of the Tape and then use my 1 inch flexible putty knife to assist in lifting away the old Drywall tape
Use paintable caulk to patch small ceiling cracks, not drywall compound! If you use drywall compound the crack is likely to reappear plus you have to sand it, ugh! Prepare a small bowl with soapy water (about a cup of water + a tsp of dish soap), put enough caulk on the crack to fill it, dip your finger or a scraper in the soapy water and smooth over the caulk, wait till it's dry and paint!
