Proper size selection is important to control the shape of the
sealant bead. It must be sized to fit the application and function
as a bondbreaker to prevent back-side adhesion of the sealant.
JOINT PREPARATION
Joints must be cleaned thoroughly, removing any foreign materials. To ensure a good sealant bond, joins
must be clean and dry when the new sealant is installed.
INSTALLATION AND SEALANT PLACEMENT
Place a small bead of sealant to tack fillet in place prior to applying the sealant bead. Refer to sealant
manufacturer鈥檚 recommendations.
PRECAUTIONS
Do not puncture, over compress or stretch during insertion. Do not use with hot applied sealants. Tests for outgassing of cold applied sealants shall be
made in accordance with ASTM Test Method C 1253. Sealant compatibility should be confirmed by the sealant manufacturer. Compatibility characteristics
of sealants in contact with sealant backings can be determined by ASTM Test Method C 1087.
