Features To Look For In A Caulking Gun

Thrust ratio is the amount of force of caulk gun applies to the caulk tube on each squeeze of the trigger. Don’t get confused with speed! The higher the thrust ratio of a caulk gun is, it will be able to apply more pressure with less hand effort. This thrust ratio for a caulk gun is important for the manual caulk gun buyer. This is an important key factor for manual caulk guns.

• High Thrust (18:1): best for thick material like silicone, polyurethane, and elastomeric sealants for stucco.

Speed Control(For electric caulk gun)

Many electric guns come with variable speed settings, which allow you to apply caulk slowly for detailed work! And you can also speed up for long, straight work. This controls the flow based on job type and caulk type.

Battery Life (For electric caulk gun)

This is another important thing to consider if you’re looking to buy an electric caulk gun for stucco. Based on your work type, look for the right models. In my opinion, 1st check for the rechargeable lithium-ion batteries (which mostly come with) or AA/AAA batteries, look for an electric caulk gun that can dispense at least 20 plus tubes per charge. If you’re working on a larger project, it is recommended to use or carry extra batteries and a charger with you.

Dripless Design

The dripless design gun is best for preventing mess and stopping unnecessary dripping while fixing stucco patches. A dripless caulk gun stops the flow of caulk as soon as you release the trigger.

• Prevents mess on your hands or work surface
• Saves caulk by stopping unnecessary dripping
