APPLICANTS' STATEMENT OF MATERIAL FACTS REGARDING MAXIMUM ROUGHNESS SURFACE PREPARATION LSSUE AS TO WHICH THERE IS NO GENUINE ISSUE i
1.
Applicants prepare steel substrate surfaces for l
the application of primer coatings by sandblasting, power tooling, and hand sanding.
None of these methods of surface preparation should produce a maximum surface profile in excess of 3 mils.
Applicants utilize a blast medium, coarse c
sand, that limits the surface profile of sandblasted steel substrate, and Applicants' quality procedures ensure that primer-applied to-steel surfaces completely covers the l
profile.
On this basis, the manufacturer of the primer coatings used on steel surfaces at Comanche Peak has approved Applicants' steel surface preparation procedures, so far as the procedures do not specify a maximum allowable surface height.
2.
Applicants' construction procedure governing the profile height of steel substrate surfaces prepared for primer coatings is consistent with the standards of Steel Structures Painting Council Surface Preparation 1
