Things To Look For When Choosing A Caulk Gun

While selecting the ideal caulking gun may appear to be a simple task, there is actually a lot to learn about these devices. It’s worth looking at the power, thrust ratio, rod type, and other factors. Consider how often you will use the caulk gun and its overall purpose. A less-expensive gun with basic features may be the best solution for those one-and-done or particularly messy projects. A better-quality, all-encompassing gun is typically the route to go for regular household repairs or long-term tasks. When choosing a caulk gun, here are a few things to keep in mind.


Hand and wrist strain can result from repeatedly pressing the trigger, which is why motorized caulking guns are now becoming increasingly popular. Powered caulking guns were originally designated for commercial and industrial projects when they first reached the field.

But now, many people are realizing the advantages of having the gun automatically distributing the sealant so they can concentrate on making a smooth seam. It’s also worth noting that the thrust ratio is inapplicable without the hand trigger (more on that in a while). Rather, a gentle pull on the finger trigger controls the discharge volume.

Thrust Ratio

Check the thrust ratio on the physical packaging or in the online product description of the caulking gun. When the hand trigger is pressed, the thrust ratio refers to the amount of pressure created. With each compression, the higher the ratio, the more force is applied.

This is significant because, in contrast to thinner sealants, thicker sealants require a higher thrust ratio to be dispensed. The thrust ratios typically range from 3:1 to 28:1. Tools with lower thrust ratios are suited for dispensing thin caulks such as water-based latex caulk, whilst greater thrust ratios are required for pouring thicker ones such as epoxy sealants.

Type of Rods

There are two primary varieties of gun rods, and their effectiveness varies significantly. Caulking guns with ratchet rods are probably most widely accessible at DIY and hardware stores. This is the most basic type of caulking gun, with a ragged pushrod attached to a spring that has a trigger. To operate the device, draw the rod back all the way, snip the caulk tube tip open, slide the tube into the gun, and then squeeze the trigger to release the caulking.

The smooth rod caulking gun is the other kind of rod available. They’re a little less popular and a lot pricier, but they perform effectively and are more user-friendly. This caulking gun typically has a pressure ratio of 10:1, which means it can discharge more sealant with less effort on your part. A single push of the trigger distributes twofold as much caulk as a 5:1 ratchet rod gun.

Caulking guns are available in a variety of sizes from basic home repairs to powered guns for professionals who deal with sealants non-stop. Using a caulking gun necessitates a lot of repetitive action, so if you will be using one frequently, spend a bit extra on a gun that fits comfortably in your hand and triggers easily. We are sure it would be a good investment for the long-term.
