1. A modular sealant system consisting of:
a first panel selectively coupled to a first horizontal member of a modular wall;
a second panel selectively coupled to a second horizontal member of the modular wall;
a backer, wherein the backer is:
selectively coupled to a first prong of a first vertical member of the modular wall and selectively coupled to a first prong of a second vertical member of the modular wall, and
configured to register the first panel and the second panel relative to each other;
a geometry defined by an edge of the first panel, an edge of the second panel, and an end face of the backer; and
a sealant having elastomeric properties configured to adhere and conform to the geometry;
wherein the sealant occupies the geometry and forms a seal configured to prevent an ingress or an egress of air, moisture, and contaminants.
