Depends on a few factors really --the actual glue itself, the weather [warm/cold etc.] your own body-chemistry and exposure to water [showering ] ....what type of system and glue are you wearing/using at the moment? I assume whatever glue you are using, is compatible with lace and if you are getting 3 weeks wear from your present bonds, the fact that you may choose to wear lace should not change that length of bond.
