The caulking gun is an essential tool for any DIY enthusiast or professional tradesperson. Whether you’re sealing gaps around windows and doors or applying a fresh bead of caulk to your bathroom tiles, a caulking gun will make the job easier and neater. In this article, we’ll walk you through the steps on how to use a caulking gun from Bunnings, Australia’s leading home improvement and DIY store.
Step 1: Choose the right caulk
Before you begin, it’s important to select the right caulk for the job. Bunnings offers a wide range of caulks, including silicone, acrylic, and polyurethane. Each type of caulk has its own specific uses and properties, so be sure to read the labels or ask for assistance from the knowledgeable staff at Bunnings.
Step 2: Load the caulk tube
Once you have the right caulk, it’s time to load the tube into the caulking gun. Start by pulling back the rod on the gun and placing the caulk tube into the barrel. Make sure the nozzle is facing forward and towards the tip of the gun. Push the rod back in to secure the caulk tube in place.
Step 3: Cut the tip of the caulk tube
Using a sharp utility knife or a caulk gun cutter, cut the tip of the caulk tube at a 45-degree angle. The size of the opening will depend on the width of the gap you’re filling. For smaller gaps, make a smaller opening, and for larger gaps, make a larger opening. Be careful not to cut too much off as you can always cut more if needed.
Step 4: Start caulking
With the caulk tube loaded and the tip cut, you’re ready to start caulking. Hold the gun at a 45-degree angle to the surface and squeeze the trigger. Apply steady pressure to the trigger as you move the gun along the gap or joint you’re filling. Keep a steady pace and try to move smoothly for an even bead of caulk.
Step 5: Smooth the caulk
After you’ve applied the caulk, use a caulk smoothing tool or a wet finger to smooth the bead. This will help create a neat finish and ensure the caulk sticks properly. You can also use masking tape to create clean lines and remove it before the caulk dries for a professional-looking result.
Using a caulking gun from Bunnings is a simple and effective way to seal gaps and joints around your home. By following these steps, you’ll be able to achieve a professional finish and maintain the integrity of your walls, windows, and tiles. So grab your caulking gun and get ready to tackle your next DIY project with confidence!
Choosing the Right Caulking Gun
When it comes to choosing a caulking gun, there are a few factors to consider that will help ensure you select the right tool for the job. Here are some things to keep in mind:
- Type of Caulk: Different types of caulk require different caulking guns. For example, latex caulk typically requires a standard caulking gun, while silicone caulk may require a more heavy-duty gun.
- Size of Cartridge: Caulking guns come in different sizes to accommodate different cartridge sizes. Make sure to choose a caulk gun that is compatible with the size of cartridge you will be using.
- Thrust Ratio: The thrust ratio of a caulking gun determines how much pressure is applied when squeezing the trigger. Higher thrust ratios are generally better for thicker or harder materials, while lower ratios work well for thinner and softer materials.
- Comfort and Ergonomics: Consider the weight and grip of the caulking gun. Look for a gun that feels comfortable in your hand and has a grip that is easy to hold for extended periods of time.
- Quality and Durability: It’s important to choose a caulking gun that is made from high-quality materials and built to last. Look for guns with a sturdy construction and positive customer reviews.
By taking these factors into account, you can select the right caulking gun for your specific needs and ensure that your caulking projects are successful.
Consider the Type of Work
When using a caulking gun, it is important to consider the type of work you will be doing. Different types of caulking materials are designed for specific uses, so it is important to choose the right type of caulk for your project.
If you are working on an interior project, such as sealing trim or baseboards, you will want to use an acrylic caulk. Acrylic caulks are easy to work with and can be painted over once they have dried. They are also good for filling gaps and cracks in drywall.
If you are working outdoors or in a wet area, such as a bathroom or kitchen, you will want to use a silicone caulk. Silicone caulks are waterproof and flexible, making them perfect for sealing joints and gaps in areas that are exposed to moisture.
If you are working on a project that requires a high level of adhesion, such as sealing a bathtub or a countertop, you may want to use a construction adhesive instead of caulk. Construction adhesives are stronger and provide a more permanent bond than traditional caulks.
Before starting your project, make sure to read the labels on your caulk cartridges to ensure you are using the right type of caulk for your specific needs. This will help you achieve the best results and ensure that your caulking job is durable and long-lasting.
Look for a Comfortable Grip
When choosing a caulking gun from Bunnings, one important factor to consider is the grip. Look for a gun that offers a comfortable grip, as this will make the process much easier and more efficient. A comfortable grip will also help to reduce hand fatigue and allow you to work for longer periods without discomfort.
There are different types of grips available, such as pistol-grip, T-grip, and dripless grips. Pistol-grip caulking guns are the most common and are comfortable to use for most applications. T-grip caulking guns are designed for better control and can be a good option for more precise work. Dripless grips have a mechanism that prevents the caulk from oozing out when you release the trigger, minimizing mess and waste.
When selecting a caulking gun with a comfortable grip, consider the size of your hand and the type of tasks you will be performing. Test different models and see which one feels the best in your hand. It’s also a good idea to try out the trigger and make sure it moves smoothly without any stiffness or resistance.
Remember, using a caulking gun requires precision and control, and having a comfortable grip plays a crucial role in achieving professional results. So take your time to find a gun with a grip that suits your needs and preferences.
Prepping the Surface
Before you start caulking, it’s important to properly prepare the surface you’ll be working on.
Clean the surface:
Make sure the area is clean and free of any dirt, dust, or loose debris. Use a damp cloth or sponge to wipe down the surface and remove any grime. Allow the surface to dry completely before proceeding.
Remove old caulk:
If there’s old caulk present, use a caulk removal tool or a putty knife to scrape away the old caulk. Be careful not to damage the surface as you remove the old caulk. Clean up any leftover residue with a solution of warm water and soap.
Repair any damage:
If there are any cracks, holes, or other damage on the surface, it’s important to repair them before applying new caulk. Use a suitable filler or patching compound to fill in any gaps or damage. Smooth out the repaired areas and allow them to dry completely according to the manufacturer’s instructions.
Mask off the area:
If necessary, use masking tape to protect adjacent surfaces, such as walls or countertops, from getting caulk on them. Place the tape along the edges of the surface, ensuring that it’s securely attached and creating a clean border.
Prime the surface:
Depending on the type of surface and caulk you’re using, it may be necessary to apply a primer before caulking. Check the manufacturer’s instructions to determine if priming is required, and if so, apply the primer according to the instructions and allow it to dry completely.
Inspect the surface:
Before applying caulk, take a close look at the surface to ensure it’s fully prepped and ready for caulking. Check for any missed debris, remaining old caulk, or other imperfections. It’s crucial to start with a clean and well-prepared surface for a successful caulk job.
Clean and Dry the Area
Before using a caulking gun, it is important to clean and dry the area where you will be applying the caulk. This will ensure proper adhesion and a long-lasting seal.
Start by removing any old caulk or sealant using a caulk remover tool or a putty knife. Carefully scrape away any loose or peeling caulk, being careful not to damage the surface beneath. Wipe away any dust or debris with a clean cloth or brush.
Next, use a mild detergent and water solution to clean the area. Scrub the surface gently with a sponge or scrub brush to remove any dirt or grime. Rinse the area thoroughly with clean water and allow it to dry completely.
It is important to ensure the surface is completely dry before applying caulk. Moisture can interfere with adhesion and compromise the effectiveness of the sealant. If necessary, use a clean cloth or paper towel to dry the area completely.
Once the area is clean and dry, you can proceed with using the caulking gun to apply the caulk. Following these steps will help to ensure a clean and long-lasting seal.
Remove Old Caulking
Before you can apply new caulking, it’s important to remove any old caulking to ensure a clean surface and a proper bond. Here are the steps to remove old caulking using a caulk gun:
Materials You’ll Need:
- Caulk remover tool
- Razor scraper
- Plastic or glass scraper

After you have successfully removed the old caulking, you will be ready to apply new caulking using your caulk gun. Follow the manufacturer’s instructions for applying the new caulking, and be sure to allow it to fully cure before exposing it to any moisture or weather.
Loading the Caulking Gun
Before you can start using a caulking gun, you need to load it with a tube of caulk. Follow these steps to ensure a proper loading:
Step 1: Choose the Right Caulk
First, you need to choose the right caulk for your project. Consider the type of material you will be working with and whether you need a waterproof or paintable caulk. Read the labels and choose a caulk that suits your needs.
Step 2: Prepare the Caulking Gun
Next, prepare the caulking gun by releasing the pressure rod at the back. Most caulking guns have a lever or a trigger that you can pull or push to release the rod. Make sure the rod is extended to its full length.
Step 3: Cut the Caulk Tube Nozzle
Use a utility knife or a caulk tube cutter to cut the nozzle of the caulk tube at a 45-degree angle. The size of the nozzle opening will depend on the width of the joint you will be filling. For wider joints, cut a larger opening.
Step 4: Insert the Caulk Tube
Insert the caulk tube into the caulking gun with the nozzle facing outwards. Ensure that the nozzle is fully seated in the metal cradle at the front of the gun.
Step 5: Secure the Caulk Tube
To secure the caulk tube in place, push the pressure rod against the bottom of the tube. Some caulking guns have a hook or a clip that you can engage to hold the tube in place.
Step 6: Test the Caulking Gun
To test the caulking gun, squeeze the trigger or lever gently to make sure the caulk starts flowing smoothly from the nozzle. If the caulk does not flow or if it is difficult to squeeze the trigger, check that the caulk tube is securely loaded and that the nozzle is not blocked.
With your caulking gun properly loaded, you are now ready to use it for your project. Follow the manufacturer’s instructions on how to apply the caulk and fill the joints. Remember to keep the nozzle moving smoothly along the joint for a clean and even application.
Note: Always wear the appropriate safety gear, such as goggles and gloves, when working with caulk or any other construction material.
