A sealant applicator is used with a sealant container and has a frame, a plug contained within the frame, a wiper connected with a first frame end, a biasing member connected between the frame and the plug, and a coupler that couples the sealant applicator with the sealant container. The frame has first and second opposing frame ends and defines a pathway between the opposing frame ends. The plug slides between the opposing frame ends along the pathway. The wiper wipes a portion of the plug when the plug slides to the first frame end. The biasing member biases or urges the plug toward the first frame end. The sealant applicator extends within the sealant container when coupled with the container. In other aspects, the plug further includes a tip and an opposing base, the plug is oriented with the base facing the second frame end, and the tip includes at least one of a group that includes a convex surface and a concave surface. The plug further may include a shelf that is located between the tip and base and has a surface that faces away from the second frame end, the surface being one of a group of surfaces that includes concave and convex surfaces.
