Tower Tech2 TM is generally considered a non-priming sealant. It is the user’s responsibility to check the adhesion of the cured sealant on typical test joints at the project site before and during application consult Technical Services for additional information.

Surfaces to be caulked must be dry and free of all dirt, dust, oil, mildew, loose paint, old caulk, or other contaminants. Bare surfaces should be primed before caulking. Only apply when sealant, surface, and air temperatures are above 40° F and rising. Do not apply on surfaces that exceed 120°F, or when rain is expected.


Tower Tech2 TM comes ready to use. U-shaped joints should have the proper size backer rod or bond breaker tape installed to prevent 3 point adhesion. The sealant must reach the deepest point of the joint. Remove excess with a clean rag and water. Tooling the joint flush with a putty knife is recommended. Tooling results in the correct bead shape, a neat joint, and maximum adhesion. 90° joints can be tooled smooth with a moistened rag to a minimum bead size of 3/8”.

CURE TIME @ 75° F (24° C) 50% relative humidity Joint Size ½” X ¼”

Tooling Time: 15 Minutes
Tack Free Time: 60 Minutes

The cure of Tower Tech2 TM varies with temperature and humidity. Lower temperatures and humidity will extend curing times.
