Nonshrink Grout
**************************************************************************
NOTE: Some nonshrink grouts derive their nonshrink
properties from an increase in volume of metal due
to oxidation. Where oxidation is not desired for
appearance sake, specify nonmetallic grout.
**************************************************************************
ASTM C 1107, with no ASTM C 827 shrinkage.
[Grout shall be nonmetallic.]

SHOP PRIMER
**************************************************************************
NOTE: Shop primer specified is for structural steel
located inside a typical building. For buildings
that will have a lot of structural steel exposed to
view inside a building (i.e. hangars, maintenance
shops), exterior structural steel, or other
locations that will require a better shop primer,
use of a zinc rich primer and epoxy coating system
is recommended.
**************************************************************************
SSPC Paint 25, (alkyd primer) or SSPC PS 13.01 epoxy-polyamide, green
primer (Form 150) type 1, except provide a Class B coating in accordance
with AISC 316 and AISC 317 for slip critical joints. Primer shall conform
to Federal, State, and local VOC regulations. If flash rusting occurs,
re-clean the surface prior to application of primer.
