Frequently asked questions

What is a power caulking gun?

A caulking gun is a mechanical tool that fills cracks and gaps using a cartridge or a tube which contains the caulking material (silicon or latex). A power caulking gun operates using a power source (pneumatic, Li-ion battery or electricity from a power source), and the main function of most caulking guns is filling.

What are the pros and cons of power caulking guns?

Caulking done by a battery powered caulking gun is more consistent and reliable – it provides a much neater end-result. You get to regulate the amount of sealant coming out of the tube and this allows you to be more precise and consistent. It’s also less time consuming and most people find they waste less caulking material using a power gun.

On the other hand, power caulking guns are usually costly and are really only cost-effective for professionals, people who take their D.I.Y more seriously, or if you think you’ll need to use the gun one several occasions.

How long do rechargeable caulking guns last for before they need a recharge?

Battery timing varies with different caulking guns, but on an average it takes about 30 minutes to charge an electric caulking gun, which can then dispense more than 100 cartridges on a single charge.

How do you load a cordless caulking gun?

The loading mechanism can be different with different types of cordless caulking guns, but generally you have to release the trigger at the rear end of the gun using your thumb, then load the caulking tube by pulling the plunger, and then release it back to its initial position.

What’s the best air powered caulking gun?

The Campbell Hausfeld is the best air powered caulking gun according to our findings because of its light-weight, durability and simple functionality. It also features accurate flow control that ensures no caulking material is wasted during its operation.
