Claim 0:
1. A pressurized construction adhesive applicator system comprising:
a canister having a volume;
a one-part moisture curable construction adhesive in the volume;
a lid forming a seal with said canister;
an applicator wand having a body having a single input located on a bottom side of the body and an output, the body being in fluid communication with said one-part moisture curable construction adhesive via a single tube that is connected to the body via a ball valve at the single input, the ball valve actuated between a closed position to an open position by a manually operated ball valve handle, the applicator wand additionally having a trigger that upon depression brings said one-part moisture curable construction adhesive from the canister into the body through the ball valve at the single input when the ball valve is in the open position for ejection from the output, the trigger being positioned on the bottom side of the body behind the single input; and
a pressurant in the volume in an amount sufficient to urge said one-part moisture curable construction adhesive from the volume through a barrel and out of a nozzle of said applicator, a product flow knob mechanically coupled to a needle via the interaction of a needle spring and a ball bearing to meter said one-part moisture curable construction adhesive from said nozzle as an extruded bead with depression of said trigger;
wherein the one-part moisture curable construction adhesive can be applied to vertical surfaces without foaming, solvents, or resort to mechanical pumps.
