How to use

PSA-backed (pressure sensitive adhesive) lapping film is extremely easy to use. Simply peel off the paper backing and press it down on the blank. Avoid getting air bubbles between the film and the blank.

3M Lapping Films should be used with one of these lubricants:

  • Refined olive oil
  • Oleic aсid

Please note that length of films is 14 cm (5½"). When film is mounted on standard 15 cm (6") blank, take into account the difference in length when sharpening.

When Lapping Film loses abrasive ability, gently detach it from the blank and attach new film.
