Abstract: A gap molding and associated methods reduce accumulation of undesirable material in a gap. A gap molding comprises a top portion configured to at least partially bridge a gap, and a retention portion configured to frictionally engage with at least one side of the gap. The gap molding may be configured with a taper in order to smoothly transition from the surfaces on either side of the gap. The gap molding may comprise silicone or other suitable material. The gap molding may desirably be placed between appliances, countertops, and/or the like in order to provide improved aesthetics and/or reduce accumulation of food waste and other debris.
