Caulking guns are used by siding installers, framers, plumbers, and many of the other trades. Canadian Theodore Witte of Chilliwack filed for a patent on his “Puttying-Tool” in 1894. Early caulk guns had a barrel that needed to be filled from bulk sealant. Standardized disposable sealant cartridges began to appear in the 1940’s. The standard caulk gun holds a tube/cartridge that contains about 10 ounces of material.

How is a caulking gun used?

Cut the tip off the tube of sealant

Puncture the seal down inside the tip/spout

Pull the plunger back

Insert the tube into the caulking gun canister tray

Pull the caulking gun trigger to dispense the sealant

Caulking caps and tube tip extensions are available.

What are the different types of caulk guns?

Caulking guns that handle 29-oz. tubes/cartridges
Pneumatic (air) powered guns
Battery powered guns
Sausage guns, that required a pliable tube (sausage) of sealant
Guns with two canister trays for dispensing two-part sealants and epoxy

What makes a good caulk gun?

Heavy duty construction
A plunger with a hook on the end (handy for working off a ladder)
Anti-drip action where the pressure from the plunger is released after pulling the trigger
Puncture tool that retracts out of the way to avoid getting sealant on hands

Meet in the middle | Construction Pro Tips

Caulk gun tip:

Meet in the middle: When you have a long bead to run and you can’t get it done in one shot, don’t start again where you left off. Instead, use the caulking gun and start at the other end and meet in the middle. It’s hard to continue a bead once you’ve stopped without creating a glob. Also, try to keep the meeting place somewhere other than eye level.
