Masking With A 3M Hand Masker
What happens here
After applying the initial masking, conduct a thorough final inspection to ensure the window is completely protected. Check all corners, edges, and the entire surface of the 3M 72-inch masking film for any leaks, holes, or exposed areas where paint could potentially seep through. If the masking film's edges are not perfectly straight, or if there are any small gaps between the film and the frame, you can apply an additional run of 3M 1-inch 2020 masking tape to cover these areas, effectively sealing them. For those new to masking, using 1.5-inch wide masking tape (instead of 1-inch) can offer a larger margin for error, making the process easier, though it is generally more expensive. A critical warning for exterior projects: 3M 2020 tape has high adhesion and is designed for same-day application and removal. Do not leave it on your windows or exterior surfaces overnight, as it can bond to the surface, making removal difficult and potentially causing damage.
