How to Use a Caulk Gun?
To use a caulking gun, you need to have these tools: caulk, caulking gun, scissors, and a nail.
Achieving perfect caulking depends mainly on three things: the position of your caulk gun, the opening cut you make, and the speed with which you use the gun.
Here’s how to use a caulk gun:
- First step: put you’re the thumb on the plunger at the rear of the gun and press the release. Release the plunger at the back of the gun.
- Second step: pull back the plunger, and fix the tube in the gun. Have the nozzle in the front. Push the plunger towards the back of the tube. Once the caulk is well placed, remove your thumb.
- Third step: to load your caulking gun, you will need to cut the tip of the caulk to make the hole fit for the size of the gap you’re sealing. It’s advisable that you cut smaller than you first thought; to prevent ending up with a bigger hole. You can re-cut it if it’s too small. Larger gaps require larger cut openings, be proportionate.
- Fourth step: now you’re going to puncture any foil seal, making the caulk flow easily. Each caulk tube contains a foil seal between the nozzle and the cylinder. To puncture the seal, push a nail, a coat hanger, or pin through the hole you made.
- Fifth step: position your caulking gun at 45 degrees along the target gap.
- Seventh step: while pushing the gun towards you, squeeze its trigger slowly and keep a steady pace. When you feel unable to squeeze the trigger, release it. In this case, it would spring back automatically. Squeeze again when it reverts back to its initial position. You will always get more caulk released at the end of each squeeze, so mind how much pressure you put throughout.
- Eighth step: finally, using your finger- or a damp fine cloth-, smooth the caulk.
