eliminate voids or bubbles and ensure that
the sealants press completely against the
sides of joints. Joints should be tooled to a
concave finish. Soaps or solvents should
never be used in tooling. This will cause
improper curing, adhesion failure, or color
change.
Proper tooling of joint. (SWRI)
Proper mixing, application, and tooling includes:
•
Recommended temperature ranges,
typically 50 to 80 degrees F.
•
Mixing only complete packages of
materials.
•
Mixing for proper amount of time.
•
Keeping air out of sealant during
mixing.
•
Using properly sized nozzles and slopes
to fill joints.
•
Tooling by compression, for adequate
adhesion.
•
Avoiding use of soaps or solvents in
finishing joints.
