Abstract: In a method for tinting caulking, a quantity of caulking is sealed within and toward one end of an elongate, pliable casing. The unfilled portion of the casing is then unsealed, and a quantity of tinting agent, such as paint, is introduced into the casing, which is then resealed. The caulking and tinting are then intermixed by manual kneading of the casing until the caulking has acquired a desired colour. The sealed end of the filled portion of the casing is then unsealed, the casing is inserted into a caulking cartridge with the filled portion disposed toward the nozzle end of the cartridge, and a slidable plug is inserted into the cartridge. The cartridge may is then loaded in a conventional caulking gun, which upon actuation urges the plug against the casing so as to force the tinted caulking out of the unsealed casing and through the cartridge nozzle.
