G. Clean off excess sealant or sealant smears adjacent to joints as the Work progresses by methods and<br />

with cleaning materials approved in writing by manufacturers of joint sealants and of products in which<br />

joints occur.<br />

3.3 FIELD QUALITY CONTROL<br />

A. Field-Adhesion Testing: Field test joint-sealant adhesion to joint substrates as follows:<br />

1. Extent of Testing: Test completed and cured sealant joints as follows:<br />

a. Perform 10 tests for the first 1,000 feet of joint length for each kind of sealant and joint<br />

substrate.<br />

b. Perform 1 test for each 1,000 feet of joint length thereafter or 1 test per each floor per<br />

elevation.<br />

2. Test Method: Test joint sealants according to Method A, Field-Applied Sealant Joint Hand Pull<br />

Tab, in Appendix X1 in ASTM C 1193 or Method A, Tail Procedure, in ASTM C 1521.<br />

B. Evaluation of Field-Adhesion Test Results: Sealants not evidencing adhesive failure from testing or<br />

noncompliance with other indicated requirements will be considered satisfactory. Remove sealants that<br />

fail to adhere to joint substrates during testing or to comply with other requirements. Retest failed<br />

applications until test results prove sealants comply with indicated requirements.<br />
