Caulk is a waterproof sealant used to fill in cracks and gaps around sinks, tubs, windows, counters, and more in your home. Depending on the type of caulk you use, you can also use it outdoors to seal siding, concrete, and masonry.

Using a caulk gun might seem intimidating if you are inexperienced with home improvement. You might have visions of spewing sealant over everything but the actual opening you are trying to seal. But a caulk gun is quite simple to load and use.

"Caulking guns have evolved over the years," says George Esposito, owner of Canal Kitchens in Staten Island, NY. He notes that with older models, unless you remember to pull back on the rod, the caulk will continue to flow. "[Manufacturers] make guns today that when you release the trigger, the plunger automatically backs up and will not force the product to ooze out," he says.

Because a caulking tool is so easy to use, applying caulk is an easy DIY project for beginners and just requires the right type of caulk, an inexpensive caulking gun, and a little practice.

Quick tip: If you have a very small or awkwardly placed spot that needs to be caulked, caulk also comes in squeeze tubes and ready-to-use strips. However, a caulk gun makes for a much smoother application with less shrinkage.

It's easy to get a handle for using a caulk gun. Sealing up joints, cracks, or other gaps in your home can certainly be a DIY project even for a beginner, provided you use the correct type of caulk. If you are unsure, talk to an associate at the hardware store about the nature of your project so you can purchase the right sealant for the job.
