Re: Anyone repaired a tear in silicon?

Reinforce the patch with a cloth mesh of some sort, worked well into the caulk. Push the split edges together as closely as possible from the front to correct the alignment, and wipe away any caulk that goozes through the crack. Let set 24 hours, or until thoroughly cured.

Andrew, you are right. Usually for those one time work, we just make adjustment on the wax work instead of repairing the wax mould.
