- entire depth of the sealant. Make two vertical cuts
- several inches long, paralleling the sides of the joint
- as closely as possible and extending down from the cross
- cut. Grasp the free length of sealant and pull at a 90
- degree angle, tearing sealant from joint for several
- inches.
- 1. Sealant tears cohesively: Pass.

- NOTE ** Because there is considerable latitude in matching
- substrates, sealants, and service conditions, the
- following schedule is offered as a preliminary
- guide. Many of the sealants listed could be used
- in other applications, and many applications could
- be matched with other sealants. Consult the
- manufacturer's literature and technical
- representative for additional information.
