How to Remove Painter's Tape
Several things can go wrong when it comes time to remove painter's tape. If you wait too long, the adhesive on the tape will harden and remain stuck to the woodwork. Or if the paint sets but isn't completely dry, some of the wall paint may peel off along with the tape.
Here are solutions to some common problems:
If you're a procrastinator or slow painter, choose tape that's designed to be left on for several days. Scotch No. 2090 is one brand that uses a slow-hardening adhesive so it can be safely left on for about 14 days.
To avoid peeling paint, pull the tape off immediately or wait at least overnight for the paint to dry completely. Beware of paint that feels dry to the touch but hasn't hardened and fully bonded to the wall. It may come off along with the painter's tape.
Remove tape at about a 45-degree angle to the painted surface, as shown, to minimize the tendency for paint to peel.
If, despite waiting overnight and using a good technique, you notice the paint still peels with the tape, use the edge of your putty knife or a utility knife to cut the seal between the wall and tape before you remove the tape.
