Eons ago, my father was a flooring installer and he used to apply a bead of sealant at the bottom of the wall base to ensure a watertight seal, does anyone specify this?

Where coved base is installed against hard surface or resilient flooring, install a continuous bead of sealant under the toe of the base; ensure complete contact to exclude moisture between the floor and the base. Remove squeezeout with xylol, mineral spirits, or other solvent as recommended by the sealant manufacturer.
