2. Burnish the replica tape
3. Prepare the Gage
4. Measure
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.
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 paper to hold it firmly
in place during the burnishing process.
Firmly compress replica film using the rounded end
of the included stainless steel burnishing tool.
Apply sufficient pressure in a circular and x-y
rubbing motion to produce a replica with a uniform
pebble grain appearance. It normally takes 30 to 60
seconds to fully compress all parts of the film on
most surfaces. In general, too much compression is
safer than too little. After burnishing is complete, remove the
replica tape from the surface.
