Prepare the test surface
Locate a representative site for measurement. Clean
the surface to be tested. DeFelsko recommends the
use of the included putty to remove dust, debris, or
residual blast media from the surface.Firmly press the
putty onto the surface using your fingers, and remove.
NOTE:
Ensuring a clean surface is especially important when
using the PosiTector RTR-P to measure peak density (P
generate surface images.
Burnish the replica tape (create a replica)
Select the appropriate grade of replica tape based on the target
profile. See tape instructions for assistance.
Pull a single adhesive-backed replica tape free of its release
paper. A "bull's eye" circle of paper should remain on the release
paper (it is not used for measurement).
Apply replica tape to blasted surface. Press
the adhesive-backed ends of the tape to hold
it firmly in place during the burnishing process.
Firmly compress the foam using the rounded end of the included
stainless steel burnishing tool. Apply sufficient pressure in a
to fully compress all parts of the foam on most surfaces. After
burnishing is complete, remove the replica tape from the surface.
How to Measure
circular and x-y rubbing motion to produce a
replica with a uniform pebble grain appearance.
Excessively hard rubbing should be avoided
because the polyester film could become
distorted. It normally takes 30 to 60 seconds
