How to Load a Caulk Gun Quickly & Easily

To create a great seal, you’ll want two things: a cartridge of high-performing GE-branded sealant, like GE Advanced Silicone 2® Kitchen & Bath sealant, and a caulk gun. A caulk gun is an essential sealing tool for large sealing projects that will help you more easily create clean, professional-looking seals. With a little bit of practice, loading a sealant cartridge into a caulk gun will become second nature. Follow these four steps to set up your caulk gun and start sealing right away.

Pro Tip: For tight spaces, smaller projects, or quick repairs try using a GE Sealants squeeze tube. Just cut the nozzle tip, then squeeze out the sealant—no caulk gun required.

  1. Carefully Cut the Sealant Cartridge

    First, cut the tip of the sealant cartridge at a 45-degree angle. There are two ways to do this: either with a utility blade or, if your caulk gun has it, with the caulk gun’s tip cutting tool. For better precision, we recommend using a utility blade.Cut off less than you think you’ll need because you can always cut more.

  2. Pierce Cartridge’s Inner Foil Seal

    Your sealant cartridges may have an inner foil seal that you’ll need to pierce. Most caulk guns have an attached metal rod for this purpose. Swivel the rod around and insert it into the cartridge nozzle until you feel it puncture the inner foil. If your caulk gun doesn’t have this rod, you can use a long nail instead.

  3. Insert the Cartridge

    Once you’ve cut the tip and pierced the inner seal, you’re ready to insert the sealant cartridge into the caulk gun. First, press the release trigger on the handle and pull the plunger all the way back. Then insert the cartridge heel-first into the caulk gun. Release the plunger so that it’s seated firmly against the end of the cartridge. When the cartridge is securely loaded into the caulk gun, squeeze the trigger a few times and run a test bead of sealant. Press the release trigger to remove any pressure and stop the flow of sealant. This will help you get a feel for the pressure and speed needed to apply the sealant.

    Refer to our other How-To videos for common how to applications.

  4. Remove the Cartridge

    Once you’re finished sealing, it’s time to unload the caulk gun. Press the release trigger again and pull back the plunger. Then simply remove the cartridge. Now you’re ready to seal like a pro with high-performing GE-branded sealants that you can always trust to get the job done right.

Sealing to Prevent Pests

Caulk can serve as the first line of defense against pests by sealing gaps and cracks around a home, helping to prevent them from entering. It can be used alone as a proactive and insecticide-free approach or in conjunction with such products if pests have already penetrated the home.

  1. LOCATE THE POTENTIAL ENTRY POINTS FOR BUGS AND PESTS
    There are several areas on the interior and exterior of a home that could have gaps and cracks that should be sealed, including:EXTERIOR

    • Roof trim, roof rafters, joints, sheathing and siding
    • Exterior columns, steps, decks and porches
    • Exterior pipes and foundation
    • Doors, windows, door and window frames

    INTERIOR

    • Moldings and baseboards
    • Floorings and walls
    • Interior pipes and plumbing
  2.  FILL THE GAPS with a silicone sealant. A silicone sealant is best used:
    • To fill gaps or cracks smaller than 1/2″ by 1/2″ (unless using backer rod)
    • For inside or outside applications
    • For applications that require flexibility due to joint movement
    • RECOMMENDED PRODUCT: Advanced Silicone 2™+ Window & Door Sealant
  3. PREP FOR SEALING:
    • CLEAN THE SURFACE
      Remove old sealant, dirt and loose particles with a caulk-removing tool, or a wire brush for concrete and masonry applications, and wipe clean with a cloth. Apply masking tape to either side of the joint to create a straight edge. (Remove immediately after caulk application.)
    • READ ALL SAFETY INSTRUCTIONS BEFORE USE AND FOLLOW COMPLETELY
      Wear safety goggles, gloves, respiratory protection and protective clothing.
  4. PREPARE THE TUBE AND SEAL
    Cut the nozzle to desired bead size. Pierce the inner seal with a stiff wire or other similar object. Insert the cartridge into the caulking gun. Seal around unsightly cracks or spaces inside and outside the home. If using a caulk gun, squeeze with even, consistent pressure to control the rate at which the caulk leaves the tube.
  5. SMOOTH THE SEAL
    Use your gloved finger or a wet caulk-smoothing tool within two to five minutes of application.
  6. STORE THE TUBE AND CLEAN
    Adjust pressure to the gun so that the sealant is barely coming out of the tube. Replace the cap, or use a nail or similar object to seal the tube opening. To clean the area around the sealed joint, use mineral spirits for silicone sealants; wipe excess material from tools and clean accordingly as well.
