Masking tape isn’t what it used to be, and that’s a good thing. For nearly ten years now, high performance painter’s tapes have been making it easier to create crisp colour transitions on interior surfaces. Painter’s tapes keep stray paint out more effectively than regular masking tapes, and ScotchBlue Exterior is the first of its kind specifically for outdoor use. It’s also substantially different than any other tapes I’ve used. Instead of being based on paper, this stuff is made from thin, flexible plastic. It’s better able to conform to uneven surfaces without tearing, and it resists moisture and sunlight perfectly. You can even dunk the roll in water with no effect. Shallow score marks every 1/16” across the width of the tape means it breaks at 90º every time without wrinkling or folding. I’ve used 3M exterior for a couple of projects including touch-ups on my truck and it works better than any other tape I’ve tried. Scotch Blue Exterior costs about the same as premium interior painter’s tapes, so I expect builders will start using it both indoors and outside.
