The caulking gun is a tool that is an essential part of any DIYer’s arsenal. It allows homeowners to quickly seal up holes and cracks in the foundation and between tiles in the bathroom, as well as to create a seamless, water-tight seal between the countertop and backsplash in the kitchen. If the caulking job is done right, it’s not only an improvement to the overall look and function of the room, but it also prevents water from seeping behind the walls and into the insulation.
