Can I use scotch tape to attach a mezuzah?


Last night, after midnight, when the movers finally left, we remembered that we needed to put up our mezuzot! We couldn’t find the double-sided tape, so we put up the mezuzot with scotch tape and mounting putty. We said the berachot as well. Did we do the right thing?


Ideally, the mezuzah should be affixed with two nails, top and bottom[1] or with double-sided tape strong enough to last for a long time.[2] Scotch tape and mounting putty are not appropriate as they are less permanent.[3]

Even so, your mitzvah was performed according to a minimal standard, and your berachot were not recited in vain. Nevertheless, you should make sure to put them up properly as soon as possible, without a new berachah.[4]

[4] Agur B’ohalecha (10:6:14) suggests that since scotch tape needs to be torn to be removed, it is still minimally valid. Mounting putty would seem to be minimally valid according to Agur Bohalecha 10:17:38 and 10:18.
