Short Summary
Main recommendation: The presenter concludes that the surface being painted matters more than the brand of masking tape, and that a cheap roll of regular masking tape can perform as well as premium options on good-quality, smooth paint. He notes that Frog Tape Green performed best on rougher or bare paint when pressed firmly, while the yellow Frog Tape was not worth the money.
Key Points
- The seven tapes compared were Frog Tape green, Frog Tape yellow, Washi (professional tape from a local paint store), Scotch/3M Delicate Surface (purple), 3M Sharp Lines (blue, he noted it is about twice the price of regular blue tape), 3M regular blue painter's tape, and 3M regular masking tape (about three dollars a roll).
- The "Frog Tape" green is described as having adhesive that bonds to latex and acrylic paint and seals itself shut, while the yellow is meant for very fresh paint.
- In the bleed test, all tapes bled on the textured bare-paint area, and the regular blue and regular masking tape both showed a couple of bleed spots on the smooth paint, but otherwise performed well.
- After pressing hard, the Frog Tape green and Washi performed best on the textured area, with only a few spots of bleed.
- On the peel test done while paint was still wet, the 3M Delicate Surface and Sharp Lines peeled cleanly, and the Frog Tape green barely bonded at all, showing just one small spot of gold paint transfer.
Details Worth Noting
- Concrete instructions: For clean lines, sand the wall, paint with a good-quality, smooth (eggshell-type) paint, and use a good-quality tape. Press the tape down hard and firmly, especially on textured or bare paint, because tape that is not flattened tends to bleed.
- Concrete instructions: If the wall has rough texture, use a good-quality green Frog Tape and press it very hard before painting.
- Concrete instructions: Store Frog Tape in the plastic case provided and reseal it after use, since the adhesive can dry out and the case protects the roll edge from dents that ruin straight lines.
- The yellow Frog Tape is marked for 21 days and the green for 60 days, but the presenter was skeptical of waiting that long to remove tape.
- The presenter tested paint of different ages, including a wall from last year, one from the prior week, paint about 48 hours old, and a fresh coat dried about 15 minutes with a fan.
- The presenter's conclusion was that the yellow Frog Tape was not worth buying, and the Delicate Surface tape did not outperform the others in his test.
Bottom Line: For most painting jobs on smooth walls, inexpensive masking tape is sufficient, and the real key to crisp lines is paint quality and firm tape application rather than paying a premium for a specialty tape.
