TotalBoat Thixo, Thixo Fast, Thixo Flex, Thixo LV, and Thixo Wood fit most standard 1/10-gallon, or 10 oz. caulk guns, but the important thing to consider is that the nozzle of these specific Thixo products is slightly off center. Caulk guns that only have a small, central hole for the nozzle may not work. We advise that you only use caulk guns that allow the nozzle to be offset from the center. Do not attempt to force Thixo products into guns that do not allow the nozzle to sit properly.
TotalBoat Thixo, Thixo Fast, Thixo Flex, Thixo LV, and Thixo Wood should only be used with caulk guns that have a minimum mechanical advance of 10:1. For use in cooler conditions, where the cartridge's contents may be thicker from the temperature, warming the cartridge to 80-90°F before application is recommended to promote better flow, and to make dispensing easier.
TotalBoat Thixo Pro requires a double, or dual epoxy gun, and will not fit in a standard 1/10-gallon caulk gun.
