“wetting” of the joints. Bond surfaces equally on opposite sides. Fill sealant rabbet to a slightly concave surface, slightly below adjoining surfaces.
E. Install sealants to depths shown; when not shown, within the following limitations:
1. For normal moving joints sealed with elastomeric sealants, fill joints to a depth equal to
50% of joint width but not more than ½" deep or less than ¼" deep.
F. Spillage: Do not allow sealants or compounds to overflow or spill onto adjoining surfaces. 3.05. CURING
A. Cure sealant compounds in compliance with manufacturer’s instructions to obtain high early
bond strength, internal cohesive strength and surface durability. 3.06. ADJUST AND CLEAN
A. Upon completion, carefully examine all sealant work. Remove all damaged and defective
work, and replace with new materials.
B. Clean up and remove all surplus products, containers and rubbish, and dispose of offsite.
C. Remove spilled or spattered materials from all surfaces. When adjacent surfaces or other work has been damaged or stained as a result of sealing work, repair all damages, and remove all stains to the satisfaction of the ISU’s PM.
3.07. PROTECTION
A. Protect installed work during remainder of construction period. Ensure that it will be without
damage or deterioration at substantial completion. END 07 92 0
