Applying New Caulk with Caulk Gun Between the Tub and the Wall
If this is your first time and you are just learning how to caulk bathtub wide gap, it might get messy.
You can decide to use mineral spirits to clean up the area after caulking or even better, use a painter’s tape. This can be useful in providing a guide for you to follow when caulking. It also protects your bathtub and wall from the mess caused by caulking.
Before starting, you should measure the gap between the wall and the bathtub that you want to caulk. For ¼ inch, you will need one bead of caulk. You can use this standard to purchase the right amount of caulk for the wide gap.
- Silicone-based caulk.
- Painter’s tape.
- Caulk gun.
- Shaping tool.
- Utility knife.
Step 1: Spread the Painter’s Tape
Spread the painter's tape on top of the bathtub and the wall above. The tape should be placed one-eighth inches away from the gap. Ensure that you spread the tape to stand in a straight line so it would guide you better. You should also place newspapers on the floor near you for drips of caulk.
Step 2: Load the Caulk Gun
If you are going to use a caulk gun and cartridge, open a small hole in the tip of the cartridge with a utility knife.
The hole you make should match the gap you want to fill in. Since this is for filling in a wide gap, your hole would have to be wider. Cut the tip at a 45˚ angle. You might not need the utility knife if your caulk gun has an inbuilt slicer to cut of the tip.
Step 3: Connect the Gun to the Tube
At the bottom of the caulk gun, you would see a long, spiky metal attached. This should be placed in the opening of the caulk tube. When you insert it, it would cut the seal of the cartridge and give you access to the caulk.
Step 4: Fill the Tube
Since you are using a caulk gun to seal large gaps between the tub and the wall, squeeze the trigger and feed the caulk to the gap. Do this steadily and consistently as you squeeze the gun's trigger.
Step 5: Straighten it out
After you have filled the line with caulk, pour water on your finger and run it on the line to smoothen it.
If you are using your finger, you should clean it out with a paper towel as it cannot be washed with water. You can also use a caulk shaping tool here or the back of a teaspoon.
Step 6: Remove the Painter’s Tape
When you remove the painter’s tape, repeat the previous step.
Step 7: Clean Up
Don’t use your bathtub until the caulk has been dried up completely. You should also tidy up the work area.
