Oil, grease, dirt, chalk, particles of mortar, dust, loose rust, loose mill scale, and other foreign substances shall be removed from all joint surfaces to be sealed. Oil and greas
18、e shall be removed with solvent and surfaces shall be wiped with clean cloths. 3.1.2 Concrete and Masonry Surfaces Where surfaces have been treated with curing compounds, oil, or other such materials, the materials shall be removed by sandblasting or wire brushing. Laitance, efflorescence and loose
19、mortar shall be removed from the joint cavity. 3.1.3 Steel Surfaces Steel surfaces to be in contact with sealant shall be sandblasted or, if sandblasting would not be practical or would damage adjacent finish work, the metal shall be scraped and wire brushed to remove loose mill scale. Protective co
20、atings on steel surfaces shall be removed by sandblasting or by a solvent that leaves no residue. 3.1.4 Aluminum Surfaces Aluminum surfaces of windows and door frames in contact with sealants shall be cleaned of temporary protective coatings. When masking tape is used for a protective cover, the tap
21、e and any residual adhesive shall be removed just prior to applying the sealant. Solvents used to remove protective coating shall be as recommended by the manufacturer of the aluminum work and shall be nonstaining. 3.2 SEALANT USES NOTE: For selection of sealants and drawing details to be used for v
22、arious joints, see TM 5-805-6 for guidance. The cealant(s) to be used in the various joints indicated shall be as follows: Joint Symbol 1 3.3 APPLICATION 3.3.1 Paper Masking Tape Sealant No. 1 Paper masking tape shall be placed on the finish surface on one or both sides of a joint cavity to protect
23、adjacent finish surfaces from primer or Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- 3535789 0492633 349 compound smears. Masking tape shall be removed within 10 minutes after joint has been filled and tooled. 3.3.2 Bond-Preventive Materials Bond
24、-preventive materials for No. 2 3 4 sealant shall be installed on the bottom of the joint cavity and other surfaces indicated to prevent the sealant from adhering to the surfaces covered by the bond-preventive materials. The materials shall be carefully applied to avoid contamination of adjoining su
25、rfaces or breaking bond with surfaces other than those covered by the bond-preventive materials. 3.3.3 Backstops The back or bottom of joints constructed deeper than indicated shall be packed tightly with backstop material to provide a joint of the depth indicated. Where necessary to provide a backs
26、top for caulking compound, the joint shall be packed tightly with rope yarn. 3.3.4 Primer Primer shall be used on concrete masonry units, wood, or other porous surfaces in accordance with instructions furnished with the sealant. Primer shall be applied to the joint surfaces to be sealed. Surfaces ad
27、jacent to joints shall not receive primer. 3.3.5 Caulk and Sealant Caulk and sealant shall be applied as recommended by the manufacturer. 3.4 CLEANING The surfaces adjoining the caulked and sealed joints shall be cleaned of smears and other soiling resulting from the caulking and sealing application

NOTE B: This guide specification covers caulking and sealants. NOTE C: This guide specification is part of a series of abridged specifications (CEAGS) for use in sp
29、ecifying small jobs, minor elements of larger jobs, or repair or maintenance type work, when brief specifications with a minimum of controls will meet job requirements. This specification is based on CEGS-07920 dated March 1989, including Notice 1. NOTE D: Most CEAGS have a counterpart in the CEGS system, and if a more detailed specification is required the CEGS should be used. Also, if additional information is needed for the use of CEAGS, the notes in the CEGS should be consulted.
