Using a "gum type sealer," often referring to a sealant applied with a gun, involves loading the sealant cartridge and applying a consistent bead into gaps or joints. Based on the provided reference about using a silicone sealant gun, a key technique is applying the sealant at a specific angle while maintaining steady pressure and movement.
Here’s how to typically use this type of sealer, incorporating the key techniques mentioned in the reference:
Getting Started with a Sealant Gun
A sealant gun is a tool designed to dispense sealants like silicone, caulk, acrylic, or adhesive from a tube or cartridge. The process involves preparing the area, loading the gun, applying the sealant, and finishing the joint.
Applying the Sealant
Once your sealant cartridge is loaded into the gun and the tip is prepared (usually cut at an angle), you are ready to apply the sealant.
- Target the Gap: The primary use is to fill the gap between two objects to create a seal, prevent drafts, or join surfaces. Position the tip of the sealant cartridge at the beginning of the gap you intend to fill.
- Set the Angle: According to the reference, you should hold the sealant gun and cartridge at 45 degrees relative to the surface or joint. This angle helps ensure the sealant is pushed into the joint effectively and allows the tip to guide the bead smoothly along the surface.
- Press the Trigger and Move: Begin pressing the trigger gently to start the flow of sealant. While pressing the trigger, run it along even (meaning move the gun smoothly and evenly along the gap). The combination of pressing the trigger and moving the gun creates a continuous bead of sealant. Maintain consistent pressure on the trigger and a steady speed of movement for an even result.
- Maintain Consistency: The goal is to lay down a uniform bead of sealant that fills the entire gap. Avoid stopping and starting frequently, as this can lead to breaks or uneven thickness in the sealant line.
| Action | Technique | Benefit |
|---|---|---|
| Position Cartridge | In the gap between objects | Directs sealant where needed |
| Hold Gun & Cartridge | At 45 degrees | Helps push sealant into joint, guides application |
| Pressing Trigger | Apply steady pressure | Controls flow rate of sealant |
| Run Along Even | Move gun smoothly and consistently along gap | Creates a uniform bead of sealant |
Finishing Up
After applying the bead, you often need to 'tool' the sealant using a finger or a tooling tool to smooth the surface, ensure good contact with both sides of the joint, and create a neat finish. Any excess sealant should be cleaned up immediately.
By following these steps, especially maintaining the 45-degree angle and moving evenly while pressing the trigger as highlighted in the reference, you can effectively use a sealant gun to fill gaps and create durable seals.
