How would you seal this gap around kitchen sink plumbing?
(sh.itjust.works)
This is for a rental unit, so I'm trying to keep the cost low, while also sealing it away from silverfish. I have very fine steel wool on hand as well as a tube of DAP ultra clear flexible all purpose sealant.
Not sure if this is being facetious but yes, I do. If the materials I have on hand are a fire hazard, then I'm open to using alternatives.
