The caulking gun is a tool that is an essential part of any DIYer’s arsenal. It allows homeowners to quickly seal up holes and cracks in the foundation and between tiles in the bathroom, as well as to create a seamless, water-tight seal between the countertop and backsplash in the kitchen. If the caulking job is done right, it’s not only an improvement to the overall look and function of the room, but it also prevents water from seeping behind the walls and into the insulation.

Best Cordless Caulking Guns Buying Guide
Before choosing the best cordless caulking gun you should consider following options:
1. Power Source: Cordless caulk guns run on either compressed air or electricity. The most common is the cordless electric model.
Electric models are more expensive but are easy to use and allow you to move around easily while you work, says Plasterco.
If you choose an electric model, make sure it has enough power to drive the cartridges you will be using. Most cartridges are either standard or high-performance.
Standard cartridges are used for interior and exterior work, while high-performance cartridges are used for exterior work only.
2. Battery Life: Look at the runtime of the batteries along with the number of batteries you get in the kit.
The number of batteries will depend on the type of caulk gun you get—if it’s a cordless electric model, you’ll get one battery; if it’s a cordless pneumatic model, you’ll get two.
3. Volume: You may need a lot of power or a little depending on the jobs you’ll be doing.
If you want to do a lot of work, get a caulk gun with a longer runtime so you don’t have to stop and recharge it often.
If you only plan to do a little work, you can get a caulk gun with a shorter runtime so you don’t have to carry a lot of batteries with you.
4. Size: Cordless caulk guns are available in different sizes to accommodate different jobs.
You can get a handheld model that’s easy to carry around and take anywhere, or you can get a stationary model that you attach to a pneumatic hose.
