Save your hands and get the right thrust ratio caulking gun!
Higher number ratio = easier to squeeze. In cold weather or thick sealants, an 18:1 or higher is a huge help. Even on sealants that flow well, a thrust ratio higher than 12:1 requires notably less effort.
The tradeoff is less volume is extruded with each squeeze, so you won’t be able to drag the bead as far compared to a lower ratio gun. However, this can also be a benefit when you want super precise control over volume and okay with going slower (how I caulk).
These guns are from @albioneng, who has a dispensing solution for basically any sealant or situation you can think of. We’ve been using their guns for over a year now, and definitely won’t be going back to the cheap Amazon special we had 😂
