What thrust ratio do I need to dispense caulk?
With thicker sealants, more thrust ratio is required to dispense the sealant. Thrust ratios run from 3:1 to 28:1. Guns with lower ratios are suitable for dispensing thin types of caulk, such as water-based latex caulk, while higher thrust ratios are needed for dispensing more viscous types of caulk, such as epoxy sealants.
What is thrust ratio in a gun?
Thrust ratio is a ratio of the force you generate on the trigger versus the force that is generated to push the material. This term is only applied to manual guns. For example, a 6:1 thrust ratio means that for every 1 lb of force the user generates on the trigger, 6 times that force is pushing the material.
What type of caulk gun do I Need?
Guns with lower ratios are suitable for dispensing thin types of caulk, such as water-based latex caulk, while higher thrust ratios are needed for dispensing more viscous types of caulk, such as epoxy sealants. Look for a revolving frame to caulk around corners.
Why do different types of sealants have different thrust ratios?
This is important because different types of sealant are more or less viscid (thick). With thicker sealants, more thrust ratio is required to dispense the sealant. Thrust ratios run from 3:1 to 28:1.
What is a good thrust ratio for caulk gun?
A thrust ratio of 10:1 or 12:1 is a good average. The take away is this; don't just buy any caulking gun. Get one with a thrust ratio that matches the product you are extruding from the caulking gun.
Is there a difference between caulking guns?
Less-expensive guns tend to have a lower thrust ratio than their more expensive counterparts. A 6:1 ratio is fine for latex caulks, but adhesives, butyl and silicone caulks have a higher viscosity and require at least a 10:1 thrust ratio for proper application. Urethane and cement products require a 12:1 ratio.

Does it matter what caulk gun you use?
While your caulk gun's ratio directly impacts how easily your gun extrudes caulk, there are a couple of other factors that affect your thrust ratio. The thicker the type of caulk, the more thrust ratio you'll need to sustain a good bead. Low temperatures will often thicken caulk and also require a greater thrust ratio.

What is the difference between Rod and ratchet caulk gun?
Unlike ratchet drives that force the pressure bar to move in set small increments, the smooth-rod design of the dripless caulk gun provides you with an infinite range—a short handle squeeze for a small amount of caulk, a large squeeze to dispense more caulk.
Is silicone or acrylic caulk better?
Acrylic caulk works well for painting applications as it fills in any gaps between walls, ceilings, and woodwork trim. It cleans up well and provides a clean, neat seal. Silicone caulk, is often referred to as rubberized silicone caulk, remains flexible for most of its lifetime without peeling, cracking, or distorting.
Is a cordless caulk gun worth it?
The BIG benefit of a cordless caulking gun is that some models can handle both high and low viscosity caulk all in the same tool! The reason is most cordless caulk guns have speed dials that you can set to adjust the force or thrust used to push out the caulk.

How do you make caulking faster?
Clean the caulking gun. If there is a caulk buildup on the gun around the trigger, plunger, or plunger release, soak the gun in mineral spirits or wipe it down with a rag soaked in mineral spirits. Allow it to dry and test again.
What is thrust ratio?
Thrust ratio relates to the amount of force generated each time you squeeze the hand trigger. The higher the ratio, the more force exerted with each squeeze. This is important because different types of sealant are more or less viscid (thick). With thicker sealants, more thrust ratio is required to dispense the sealant.
What is a caulking gun?
Caulking guns are designed for one thing: to deliver a continuous bead of caulk in order to seal joints between two surfaces—for instance, gaps between window frames and jambs. The majority of the caulking guns used today are manual, meaning you squeeze a hand trigger to dispense the sealant. Powered caulking guns—the new kids on ...
What is a smooth rod caulking gun?
The smooth rod on the Newborn Drip-Free Smooth Hex Rod Caulking Gun automatically retracts after you release the comfort-grip hand trigger to prevent excess caulk from oozing out.

How does a newborn 250 caulk gun work?
With its revolving frame, the Newborn 250 Smooth Rod Revolving Frame Caulking Gun makes it easier to caulk around corners. No need to start and stop—simply rotate the barrel and the angled tip of the tube rotates to the correct position to continue running a bead. The Newborn 250 is built to last, with a zinc alloy handle to reduce corrosion, and it features a hefty 18:1 thrust ratio to easily dispense medium viscosity caulk, including butyl and acrylic. The tool also comes with a thumb release for dripless operation.
How does a caulking gun work?
Squeezing the hand trigger on a manual caulking gun forces a rod into the back of the tube of caulk, which in turn pushes the caulk out of the tube’s tip. There are two main types of gun rod that vary slightly in performance.
What is a sausage gun?
It sounds like a breakfast tool, but a sausage gun is actually designed to hold collapsible foil cylinders of sealant, called “sausages.”.

Is Chicago pneumatic air caulking gun a manual?
If you have a large caulking project ahead of you—be it sealing every window in your house or constructing a full set of cabinets in your workshop—you may appreciate the virtually effortless caulking possible with the Chicago Pneumatic Air Caulking Gun. This isn’t a manual gun; rather, it attaches to an air compressor for efficacy and ease of use in large projects.
Caulk guns: why the fuss?
Caulk guns don’t get too much attention. More often than not, they’re the cheap, throw-away tools tossed in the truck at the beginning of a job and aren’t expected to last long.
1. Extrusion: the importance of a good bead
A good caulk bead isn’t just pretty–it ensures a quality job that will hold up over time. A good caulk gun delivers a smooth, continuous bead of caulk, which is crucial for adhesion, aesthetic, and clean-up. With a smooth bead from a quality caulk gun, you can achieve better contact between your caulk and the substrate.
2. Hold and Maneuverability
A neat caulking job requires precise maneuverability of the caulk gun–if it slips from your grip, you’ll have some clean-up to do. Cheaper guns often have a gap at the trigger that can pinch your skin when you’re trying to caulk at a difficult angle.
3. Minimizing Waste
One of the downsides to caulking is waste. Even when you release the trigger, the cartridge often continues to emit caulk, which means that you’re cleaning up frequently and wasting caulk. Caulk beads don’t stop for two reasons:
Caulking with confidence
Investing in a good caulk gun can transform your tricky caulking job into a quick, effortless part of the project with a better-looking caulk bead, easier handling, and reduced waste.

Product description
Professional caulk gun with 26:1 high thrust ratio, perfect for applying thicker materials, adhesives, or when working in low temperature environments. Engineered to deliver materials smoothly and precisely, it is easy to use and produces great results. 360-degree rotating cradle barrel for easy maneuvering in and around tight working areas.
Cut the Tube Tip
Dripless caulk guns have a built-in cutter to sever the tip on caulk tubes. Just insert the tip of the caulk tube through the opening on the handle and squeeze the handle lever. As you squeeze the handle, a razor knife cleanly cuts the plastic caulk tube at precisely the right distance from the tip.
Pierce the Caulk Tube Seal
One of the most convenient features of dripless caulk guns is the built-in wire rod for breaking the foil seal at the bottom of the caulk tube spout.
Advance the Pressure Rod
The smooth-rod dripless caulk gun works with a simple mechanism. A spring-loaded metal plate locks the pressure rod wherever you stop it.
Release the Pressure Rod
Releasing the pressure on the plunger rod when you want to stop the flow of caulk is much easier with dripless caulk guns. A simple push of the locking plate lever releases the pressure on the plunger and instantly stops the flow of caulk.
What is a caulking gun?
Caulking guns are used to apply caulk to joint and seams. Caulk is used to seal joints. It has traditionally been used in the wooden ship building industry and to close gaps between structures. In buildings it is used in order to create energy efficient spaces as it can ensure that heat stays in the room it belongs.
How much thrust does a ratchet gun have?
Most ratchet guns have a thrust ration of 5:1. These can be tricky to use as you may find it difficult to control the flow of the caulk. In order to open the caulk cartridge you need to cut it open with a knife and release the seal.
