Aginist itself? Can you explain a bit more. I was pulling it off at a 90 degree angle.
So far I know to pull it off right after I am done painting, correct?
Yeah, you definitely dont want to pull it at a 90 degree angle. That is actually the worst way you can pull tape off, it is has the most probability of "tearing" the new paint film and leave a jagged edge.
Take this mock photo for example and pretend what i just painted is on the bottom side of the tape. See how im pretty much pulling at a 180 degrees. Im pulling the tape against itself. Does that make sense with the pic?
I wouldnt pull it off immediately after painting, i would let it set up one or two minutes first, but dont let it dry all the way. Another benefit of pulling it against itself, is that it helps to "cut" the paint line and leaves a nice even paint line, even if you have to wait to unmask it till its already dry.
