A caulker 10 dispenses two viscous components contained separately in inner and outer molded resin chambers. The outer chamber 12 holds one of the components 14 around the inner chamber 11 and is generally cylindrical with standard dimensions to fit existing caulking guns and dispensing equipment. The second component 15 is held within collapsible inner chamber 11 aranged inside outer chamber 12 and having accordion pleats that collapse when axially compressed. Inner chamber 11 has a rear end filling opening 17, and a molded resin plunger 13 fitting closely within outer chamber 12 is secured to the rear end of inner chamber 11. The forward regions of both chambers join and form passageways merging at the forward end of caulker 10. Inner chamber 11 is sealed by an openable barrier 22, and a removable closure element 26 seals outer chamber 12. When barrier 22 is opened and closure element 26 is removed and a nozzle 30 with a static mixer 31 is attached, plunger 13 can advance within outer chamber 12 and collapse inner chamber 11 forcing both components 14 and 15 from their chambers and through static mixer 31 before being dispensed out nozzle 30.
