What Is Thrust Ratio In A Caulk Gun?
Thrust is the pressure applied on a caulk tube when pressing the trigger. That causes the caulk to extrude out of its shell. The piston present in the caulk gun is responsible for applying this thrust.
Furthermore, the thrust ratio is the ratio between the generated force upon pulling the trigger and the developed forced to push the caulk out of the tube. Each caulk gun can either have a fix thrust ratio or an adjustable one.
Thrust ratios apply only to manual caulk guns. For instance, a thrust ratio of 18:1 refers to 1 lb of trigger force to use a power of 18 lbs to push the caulk out of the tube. Thrust ratio has been a popular way of measurement in caulk guns.
Certain adhesives, like epoxies, require a higher thrust force. As all the power in a manual caulk gun needs to be applied by the user, you can imagine how severe long term usage of such a caulk gun can be on his wrist.
How Do You Use An Electric Caulk Gun?

- Make sure to release the plunger present at the rear.
- Unscrew the nozzle in the front of your caulk gun model allows it.
- Cut the tip of the caulk tube and puncture its tip with the needle that comes attached to the gun. If your gun model does not have one, then use some other needle or pin to puncture the tube.

- Reattach the nozzle with the tube back in its place.
- Push the plunger towards the base of the tube to fix it in position. That should load the gun.
- Set the trigger on the gun to set the desired flow of the caulk from the tube.
- Position the gun at an angle of 45 degrees.
- While pressing the trigger, keep moving your hand steadily in the direction of the crack on the wall, window, etc.
- That should create a bead as long as you are pressing the trigger. Release the trigger once you are done with it.
- It will cause the gun to stop applying pressure on the tube from behind. Furthermore, the nozzle will stop leaking any more caulk adhesive.
If you need to smoothen the applied caulk bead, then you can do it with your finger or a flat surface.
