Final answer:
Caulk cap flashing should be embedded at least 3/4 inch into the masonry joint to ensure a secure and watertight seal.
Step-by-step explanation:
The question pertains to the installation of caulk cap flashing as part of masonry construction. It appears that the student is seeking guidance on how far into the masonry joint the caulk cap flashing should be inserted. In general, cap flashing, also known as counterflashing, should be embedded at least 3/4 inch (approximately 19 mm) into the masonry joint.
This depth is considered adequate to ensure a secure and watertight seal. The flashing must be inserted into a reglet—a cut or groove in the masonry—and then sealed with caulk to prevent water infiltration.
The proper installation of caulk cap flashing is crucial in protecting the underlying masonry and the structure's interior from water damage and is a common practice in construction and building maintenance.
