As with any tool, the sealant gun is useful for DIY or professional work. It can be used to fill in the gaps for windows and doors or even as tile adhesive. The first step of using a gun sealant for windows is to load it properly so that application is efficient and clean. We will provide you with a step by step guide.
What You’ll Need
- Sealant Gun: A majority of these tools come in a variety of styles and types. An example of this would be a pneumatic sealant gun or a manual sealant gun. For normal household purposes, sealant gun with basic manual settings is enough.
- Sealant Cartridge: Based on the nature of the work, we need to select the correct Cartridge. It could for example be silicone if there is waterproofing involved, or it could be caulk if it is general sealing.
- Scissors or Utility Knife: To cut the end of the cartridge seal.
- Rag: Off white fabric that is used in cleaning excessive powdered sealant.
Prepare the Sealant Cartridge
- Cut the Nozzle: Using a utility knife or scissors, carefully cut the tip of the sealant cartridge at a 45-degree angle. The angle allows for better control of the sealant flow when applying. Start with a small cut; you can always cut more if needed.
- Pierce the Inner Foil Seal: Some sealant cartridges have an inner foil seal that needs to be pierced. Most sealant guns come with an attached metal rod for this purpose. Swivel the rod and insert it into the cartridge nozzle until you feel it puncture the inner foil. If your gun doesn’t have a rod, a long nail can be used as an alternative.
Load the Cartridge into the Gun
- Pull Back the Plunger: Press the release trigger on the handle of the sealant gun and pull the plunger all the way back. This creates space for the sealant cartridge.
- Insert the Cartridge: Insert the heel (the bottom, wider end) of the sealant cartridge into the gun. Make sure the nozzle of the cartridge is pointing outward, towards the front of the gun.
- Secure the Cartridge: Release the plunger so that it sits firmly against the end of the cartridge. The cartridge should be snug in the gun, without any wobbling.
Test the Sealant Flow
- Squeeze the Trigger: Gently squeeze the trigger of the sealant gun a few times. This will push the plunger forward and start to force the sealant out of the nozzle. Be prepared for a bit of air to come out first.
- Check the Flow: Ensure that the sealant is flowing smoothly and evenly from the nozzle. If there are any blockages or if the flow is inconsistent, double-check that the nozzle is cut correctly and the inner foil seal is properly pierced.
- Clean Up: Use a rag to wipe away any excess sealant that comes out during the testing process.
Tips for Success
- Choose the Right Sealant: Different projects require different types of sealants. Make sure you select the appropriate one for your task.
- Practice First: If you’re new to using a sealant gun, it’s a good idea to practice on a scrap piece of material to get a feel for the pressure and flow.
- Store Properly: After use, release the pressure in the gun by pressing the plunger release lever. Store the gun in a dry place, and if there’s any remaining sealant in the cartridge, seal the nozzle to prevent it from drying out.
Loading a sealant gun may seem daunting at first, but with a little practice and the right tools, you’ll be applying sealant like a pro in no time. Whether you’re working on a home improvement project or a DIY craft, these steps will help you achieve professional-looking results.
