September 2016 – Section #070800 Commissioning of Thermal of 12 and Moisture Protection

CxGBS Field Test No. 05, Testing of Sealants/Joints

FIELD TEST PROCEDURE for SEALANTS AND JOINTS.

A. Purpose: To visually observe and document during the construction process that the adhesion of sealants perform successfully. This field test does not evaluate the performance of a sealant joint as a weatherseal, but rather only evaluates the characteristics of the adhesive bond relative to the cohesive strength of the sealant in a particular installation. Since any failures that result from use of this test method are intentionally induced, they do not necessarily mean that the sealant joint will not perform as a weatherseal. Positive tests results are required to confirm the adequacy of the design and the construction installation technique prior to proceeding.

B. Scope: The area to be tested shall include any windows, doors, vents/grilles, mechanical penetrations, or intersection of materials featuring the use of sealants/adhesives on the building envelope. 1. Test all envelope penetrations featuring sealants.

C. CxGBS: CxGBS is to direct and witness testing executions. 1. CxGBS will select the locations to be tested in accordance with the following guidelines:

a. “Type” of opening in the building envelope b. “Type” of material used on c. Locations where water intrusion would cause damage

2. CxGBS will determine, according to the guidelines above, the specific locations to be tested on site and annotate where each test is conducted in the field report.


D. Contractor: It shall be the responsibility of the contractor and his sub-contractors to coordinate and conduct all aspects of the test execution including but not limited to: 1. Scheduling of work to comply with test requirements 2. Advanced notification (two week minimum) to CxGBS of schedule related to work to be tested 3. Provide access, equipment, labor and utilities as required for each test. 4. Administer test as directed and witnessed by the CxA. Take any corrective action to repair

defects in materials, construction methods or workmanship revealed as a result of the testing process. Document the corrective action and make arrangements for retesting with CxGBS

E. Conditions: Test location only after the sealant is fully cured (typically within 7 to 21 days after application). 2. The nondestructive methods are most effective while the sealant is in a state of extension due

to mild or low temperatures. They are least effective during high temperature when the sealant is in a compressed condition.


a. Sharp knife and materials and applications for the immediate repair of the sealant bead.

G. Testing: Standard Field Adhesion Test: The following “Test Procedure” shall be observed as closely as is reasonably possible. Any modification to this procedure shall only occur at the direction of the CxGBS representative directing and observing the testing.

6. Deconstructive Procedure: Test joint sealants according to Method A, Field-Applied Sealant Joint Hand Pull Tab, in Appendix X1 in ASTM C 1193 or Method A, Tail Procedure, in ASTM C 1521. a. Make a knife cut across the joint. b. Make cuts along each side of the joint approximately 3” (75 mm) long. c. Place a 1” (25mm) mark on the sealant tab. d. Grasp a 2” (50mm) piece of sealant firmly just beyond the 1” (25 mm) mark and pull at a

90° angle. e. If dissimilar substrates are being sealed, check the adhesion of sealant to each substrate

separately. This is accomplished by extending the cut along one side of the joint, checking adhesion to the opposite side, and then repeating for the other surface.

f. Inspect the joint for complete fill. The joint should not have voids and joint dimensions should match those shown in the weathersealing details.

g. The destructive procedure requires immediate repair of the sealant bead. 7. Non-Deconstructive Procedure:

a. The nondestructive procedure places strain on the sealant and a stress on the adhesive bond.

b. Though termed nondestructive, this procedure may result in an adhesive failure of a deficient sealant bead, but should not cause a cohesive failure in the sealant. The results of this procedure should be either adhesive failure or no failure.



c. The non-destructive procedure can be used for continuous inspection of 100 % of the joint(s) or for any areas where deficient conditions, which are inconsistent with the practices of Guide C 1193, are suspected.

8. A test area has “PASSED” if no voids are discovered in the joint and the sealant was applied at the specified thickness.

9. A test has “NOT PASSED” if void are discovered, the adhesive fails, or improper application of sealant is discovered.

10. A “NOT PASSED” test automatically requires that an ADDITIONAL 10% of the openings sealants be tested. The sealant portions that received a “NOT PASSED” grade must be repaired and then re-tested.

H. Report: CxGBS will document the results of each test via a CxGBS Field Report and circulate the report to the Owner’s Representative, A/E and the project team.

End of CxGBS FIELD TEST No.05 SEALANTS/JOINTS TEST
