A pneumatic dispenser for dispensing viscous material, for example, mastic caulk, from a container is described. The dispenser comprises a fluid 5 supply arrangement for accepting a dispensing nozzle of the container and providing a flow of pressurised fluid to the dispensing nozzle to enable the material to be dispensed as a spray. A moveable member can be used to control the flow of pressurised fluid, for example a member disposed on a cap for closing a container containing compartment of the dispenser and/or a 10 moveable member disposed around the dispensing nozzle. The arrangement of the fluid supply arrangement allows for convenient control of the pressurised fluid flow for spraying the material. Also disclosed is a dispenser with a readily exchangeable pressure application interface for applying a dispensing pressure to the container, enabling the dispenser to be used with both cartridge 15 and foil pack containers. co 2/4 co cn 0q, CO LO IRt ,It C) LO LO LL C) N 0 co co LO co cn to 00 04 cv) 04 co 04 CY) cn co co CO 'Irt (0 C/l co co cc> to on I,- co |
