Does masking tape damage wall paint?

it depends on how long you keep the tape there and how hard you pull it off. for example if you put it on for lets say, 1 day and you take it off slowly and you don't rip, the paint will stay on. but if you keep it on for lets say, a month and you rip it of, the paint will most likely come off.

Also, it depends on how long you have had the paint on the walls. if you just painted you walls you might want to let the paint set before you put tape on it. But, if your paint has been on her for a long time, like 5 years without a new coat, you should re paint it and then let it set before you but tape on it.

Hope this helps!
