is damaged, it shall be repaired and finished with weathercoat and top coat. If primer is damaged, it shall be touched up with polyamide epoxy primer before remainder of system is applied.

Notes: (a) Fireproofing type and thickness shall be specified by Purchaser. (b) A tie coat between the fireproofing and the weathercoat is recommended by certain

manufacturers. Follow the manufacturer's instructions. (c) Prior to sandblasting, 12-gauge steel studs shall be welded to the steel for support of mesh

reinforcement. After priming, attach 19-gauge galvanized chicken-wire reinforcement to the studs. Other reinforcing details may be acceptable but shall receive Purchaser’s written acceptance prior to use.

(d) Fireproofing shall be cured for 10 days at 70°F (21°C) before weathercoat is applied. Lower

temperatures require a longer cure. Weathercoat shall be applied in two coats with the first thinned to penetrate, unless the manufacturer recommends a tie coat instead.
