Why does the paint on my freshly painted wall peel off when I remove the masking tape from the trimmed areas?
Masking tape or even “Painter’s tape” may tend to stick to fresh coatings if not removed shortly after painting or pulled improperly from the surface. When the paint is applied to the walls, it will inevitably cover over the tape as well. As the paint starts to dry, it will start to adhere to the wall as well as the tape. This “bridge” of paint from the walls to the tape will lift as the tape is removed.
To help minimize this issue, you can lightly “score” the edge of the tape with a sharp razor or utility knife. This will help break the “bridge” or “film” between the painted wall and tape. Also, try to pull the tape staying close to the wall but pull away from the painted edge.
