Masking tape or painter's tape is an important part of any paint job, allowing you to paint a clean edge or protect an area that isn't meant to be painted. Once the paint is in place, however, you're stuck with the ultimate conundrum: when to remove the tape. Taking the tape off too soon may result in a sticky mess, while waiting too long may make the tape difficult to remove, or worse yet, pull some of the fresh paint up with it.
Ideal Timing
The ideal time to remove tape from a freshly painted project is when the paint is dry to the touch, usually after at least an hour. If the paint still feels gummy, pulling the tape away will take the paint with it, so wait at least overnight until the paint feels hard and dry. If painting multiple coats on the same project, leave the tape in place until after the final coat dries.
Alternate Times to Remove Tape
Removing the tape as soon as the project is painted is an option if extreme care is used not to touch the wet paint, or when the paint is thin enough over the edge of the tape that it won't blob or drip onto the project. Some masking tapes are designed for long-term use, having an adhesive that takes a couple of weeks to cure. Such tapes are ideal for a project being painted over time and can be left in place the entire time. Standard painter's tape may become brittle and cling to the surface if left in place for many weeks or months.
Removal Tips
Remove the tape at a 45-degree angle for best results. If paint does start to come up with the tape, score along the edge of the tape with a razor blade.
