Instructional Video: Renewing Your Silicone Joints

This video shows how the right tool makes removing old joints child's play and helps you to quickly create new joints.

Perfect Joints in 3 Steps

1. Removing the old joint

Removing the old silicone residues frequently is a laborious and time-consuming task. We recommend using a snap-off blade knife to remove the old joint. 

The remaining residues can be cleaned away quickly and thoroughly with a scraper

2. Applying the new sealant

To fill the joint again, you need silicone or acrylic.

Cut the tip of the cartridge with a cartridge knife and put the tip on the gun. You can trim the cartridge to the desired length. An angled cut is very beneficial here, it helps you to apply the material at the correct angle. The best tool for this is our cartridge knife.

The height of the cut later determines the width of your joint – the more you cut off, the larger the opening and the wider the bead of material that flows out. Now insert the cartridge into the caulking gun

Hold the silicone gun at a 45° angle and apply constant pressure to get a clean joint. Draw the silicone line in a single shot and apply constant pressure. This ensures an even look.

3. Smoothing the joint

Finally, a joint smoother is used to achieve an even finish: position, smooth, done.

Experienced artisans use a finger, but if you don't have experience, you will get better results with a joint smoother. Once the drying time specified by the manufacturer has passed, your joint is finished!
