I believe that is incorrect on the masking tape. The 'day' number of the tape indicates the amount of days the tape can supposedly stay on a surface with a 'clean' removal, as long as it is not exposed to sunlight or heat. I use 60 day tape which is very low tack.
The lower the 'day' number, the higher the tack, the higher the chance of peeling off the underlying paint.
The 60 day tape will have less tack than the 14 day tape.
Typical blue painters tape is 14 day tape, relatively high tack.
"Scotch 60-Day Ultimate Paint Edge Masking Tape 2480S is a thin, strong, smooth, flat back paper tape that provides straight, sharp paint lines with a low paint ridge, indoors or outdoors. A strong acrylic adhesive holds on contact to most surfaces, yet peels away smoothly and cleanly without residue and fogging, even after 60 days in the sun or temperature exposure of up to 200°F."
Scotch Blue Painter's Tape is among the top selling painter's tape in the U.S. for a reason-it's the original blue tape that both pros and DIY painters have loved for more than 25 years. It can be used on a variety of surfaces: walls, trim, glass and metal, and it removes cleanly for up to 14 days and will not cause surface damage within that period, even if it's exposed to direct sunlight."
