The 10 oz. standard HDX caulk gun usually retails between $3-$5 at Home Depot. Keep an eye out for sales or promotions where it may be available for even less. Home Depot also carries bundles and kits that package the HDX caulk gun along with caulk tubes and other supplies.
When buying at Home Depot, you can choose the convenience of in-store pickup or delivery shipping. Make sure to inspect your caulk gun purchase for any damages or defects before leaving the store. If buying online, Home Depot provides fast and affordable shipping.
How to Use the HDX Caulk Gun
Using the HDX caulk gun is a straightforward process. Here are some step-by-step instructions on getting started:
- Load the caulk tube: open the rear gate of the caulk gun and insert the caulk tube with the spout facing outward.
- Puncture the caulk tube: use the built-in spike at the front of the barrel to puncture the inner seal of the caulk tube.
- Prime the caulk flow: hold the caulk gun upright and gently squeeze the trigger several times until caulk begins to flow out of the tip.
- Apply caulk: place the caulk tip near the desired application area. Slowly pull the trigger while guiding the tip along the surface to apply a steady caulk bead.
- Release pressure: lift your finger off the trigger to instantly stop caulk flow when finished with application.
- Cut the tip: use scissors or a sharp blade to cut the very end off the caulk tip for a neater finish.
- Release the plunger: when finished, push the rear plunger release to retract the plunger rod and release caulk tube pressure.
- Replace the spout: cap the spout or replace with a new one to seal caulk for future use.
With a little practice, you’ll quickly get the hang of using the HDX caulk gun smoothly and efficiently.
What Types of Caulk Can I Use?
The HDX caulk gun is designed for use with standard 10 oz. caulking cartridges. This includes most popular caulking materials such as:
- Silicone: for sealing windows, doors, sinks, showers, etc. Stays flexible and waterproof.
- Latex: multi-purpose caulk ideal for indoor/outdoor use. Easy water cleanup.
- Acrylic: excellent adhesion and flexibility. Ideal for gaps between dissimilar materials.
- Butyl: extremely tacky sealant resistant to vibration/movement. Good for roofing.
- Urethane: durable sealant for large expansion joints. Stays flexible in all climates.
- Epoxy: resistant to chemicals/solvents. Often used as auto/marine sealant.
Always check the manufacturer’s specifications to ensure compatibility with a smooth rod caulk gun before purchasing caulk. Avoid inexpensive “bulk” caulking compounds as they may not discharge smoothly.
How to Load the HDX Caulk Gun
Loading the HDX caulk gun with a fresh tube of caulk takes just a few simple steps:
- Fully retract the plunger rod by pressing the rear plunger release lever.
- Move the rod back as far as it will go.
- Hold the caulk gun with the barrel facing upward.
- Open the swing gate near the back of the barrel.
- Insert the new caulk tube with the plastic dispensing tip facing outward.
- Ensure the caulk tube fits snugly inside the barrel and close the swing gate.
- Keep the caulk gun upright and gently twist the caulk tube while pulling back slightly to remove any slack.
- Use the built-in puncture tool at the front of the barrel to pierce the caulk tube seal.
- Prime the caulk flow by squeezing the trigger several times.
- You’re now ready to start applying caulk!
Reloading the HDX caulk gun once a tube is empty takes just seconds. The smooth plunger rod and swing gate design make caulk changes nearly effortless.

For the affordable price, it’s impressive how sturdy this caulk gun feels. Just perform regular maintenance like cleaning and lubrication to maximize the usable lifespan.
What’s the Cost for the HDX Caulk Gun?
One reason for the HDX caulk gun’s popularity is its very reasonable price point. As mentioned previously, the standard 10 oz. model typically costs $3-$5 at The Home Depot.
For a caulk gun that feels solidly built and operates smoothly, this low cost makes the HDX very budget friendly.

Cleaning the HDX Caulk Gun is Simple
To keep your HDX caulk gun operating smoothly, it’s smart to clean it regularly after use. This helps prevent dried caulk or other buildup from clogging the rod and barrel.
Cleaning typically only takes a few minutes:
- Use a paper towel to wipe off excess caulk from the exterior barrel and tip.
- If caulk is totally dried on, soften it first with a solvent like mineral spirits.
- For the barrel interior, feed a thin rag back and forth on the rod to mop up caulk residue inside.
- Apply light oil like WD-40 to the rod and interior barrel surfaces to prevent rust.
- Use a small brush and solvent to remove any buildup from the plunger release mechanism.
- Wipe down the grip handle and trigger area to remove dirt, oil, and grime.
Proper storage is also important. Keep the HDX caulk gun in a clean, dry place when not being used for extended periods. Applying oil and wrapping it in plastic prevents corrosion between jobs.
By regularly cleaning and maintaining it after each use, your HDX caulk gun will stay in prime operating condition for years of service.

Preventing Clogs in the HDX Caulk Gun
A clogged caulk gun is incredibly frustrating. Luckily, it’s easily preventable in the HDX model with proper care:
- Always cap caulk tubes when not in use so they don’t dry out and clog the tip
- Store caulk tubes upright so caulk stays near the top by the tip
- Clean after each use to remove dried caulk inside the barrel
- Lubricate the rod to prevent caulk buildup that can restrict motion
- Avoid cheap caulk that is more prone to drying and clogging issues
- Use release solvents like mineral spirits for severe dried caulk clogs
- Soak in warm soapy water if latex caulk dries completely inside
With good maintenance habits, you can avoid most clogging problems with the HDX caulk gun. Be sure to also check for expired caulk that can dry out faster when purchasing tubes.
Durable Metal Construction
Unlike flimsy all-plastic caulk guns, the HDX features a beefy metal construction for the main components.
- The barrel utilizes thick rolled steel for durability during pressure.
- The frame provides strength and rigidity needed for leverage.
- The plunger rod uses hardened steel for smooth sliding without bending.
- The trigger and handle consist of rugged die-cast metal parts.
Metal structural components are far stronger than plastic. This allows the HDX caulk gun to withstand frequent heavy-duty use without damage or warping.
While plastic caulk guns often crack or break unexpectedly, owners report the solid metal HDX lasting for years of DIY and professional use. It’s a small investment that pays off thanks to the proven ruggedness.
How Does the HDX Compare to Other Brands?
The main alternatives to the HDX caulk gun are models from reputable brands like Albion and Newborn:
- Albion – Known for higher-end commercial-grade caulk guns. More expensive but very rugged.
- Newborn – Mid-priced brand popular with professionals. Comparable quality to HDX.
- HDX – Exclusive to Home Depot. Lower priced but solid performance.
The HDX offers similar smooth rod control to Newborn at a more affordable price point. Albion guns feel a bit more heavy duty but cost significantly more.
Unless you’ll be caulking daily as a contractor, the HDX has all the features and durability needed for standard DIY use and projects. Don’t overspend unless you truly need a commercial-grade caulk gun.
Many pros even recommend the HDX as their preferred caulk gun for routine sealing and waterproofing jobs. It really is an ideal balance of quality, price, and performance.
Tackle Heavy Duty Caulking Projects
Despite the low price, reviewers report the HDX caulk gun standing up to heavy duty use on bigger projects:
- Caulking long seams on siding, roofing, and paneling
- Filling expansion joints on masonry, sidewalks, and driveways
- Weatherproofing dozens of windows/doors around a house
- Multi-day commercial jobs requiring thousands of feet of caulk beads
- Caulking trailer exteriors and mobile home skirting
The HDX comfortably handles these larger caulking tasks that would burn out flimsier plastic caulk guns. The metal barrel easily withstands repeated pressure from big caulk tubes month after month.
If you only occasionally have larger caulking projects, the HDX is a workhorse ready for the challenge. No need to spend 3X more on commercial-grade tools.
What is the HDX Caulk Gun Warranty?
