The time required to properly burnish a replica will vary based on
the surface profile. Profiles at the high end of a replica tape grade's
range may only require burnishing for 10-15 seconds. Profiles at the
low end of the range may require up to 60 seconds. Refer to the
below examples of properly and improperly burnished replicas.
6. Carefully remove the burnished replica
tape from the surface. A small piece of
release paper remains on the top-left
corner of some grades of replica tape
to facilitate easy removal.
5. Alternate between linear (x-y) and
circular motions with the burnishing
tool to completely burnish the replica
foam until a uniform stippled gray
appearance is achieved across the
entire measurement area.
7. Inspect the replica to ensure that no
contamination from the surface is
present (e.g. dust, debris, residual
blast media).
When held up to a light source, 'points'
of light should be visible consistently
across the replica where the foam has
been compressed by the peaks of the
surface profile.
