Troubleshooting
Sealant not dispensing
Ensure the cartridge's inner seal is properly pierced and the sealant gun is correctly loaded and operated.
Poor adhesion
Verify that surfaces were clean, dry, and free from dust or grease before application. Re-apply after thorough cleaning.
Uneven bead
Practice applying with the sealant gun to achieve a consistent speed and pressure. Use a smoothing tool for a professional finish.

Setup, Compatibility & Care
Setup: This sealant comes in a cartridge that requires a standard sealant gun for application. Ensure the surfaces to be sealed are clean, dry, and free from dust, grease, and old sealant. Cut the nozzle at an angle to achieve the desired bead width, pierce the inner seal, and load the cartridge into the gun. Apply a continuous bead of sealant using even pressure. Smooth the bead immediately after application using a damp cloth or a dedicated smoothing tool for a neat finish.
Compatibility: Adheres well to most common household surfaces including ceramics, porcelain, enamel, metal, and glass. Not recommended for use on porous surfaces like unpainted wood or some plastics. Always test on an inconspicuous area if unsure.
Care: Once cured, the sealant can be cleaned with a damp cloth and mild detergent. Avoid abrasive cleaners that could damage the surface.
