Setup
- Prepare the Surface: Ensure the surface is clean, dry, and free of old sealant, dirt, dust, and other contaminants. For best adhesion, surfaces should be structurally sound.
- Cut the Nozzle: Cut the nozzle at a 45-degree angle to achieve the desired bead size. A 3/8-inch bead is recommended for optimal joint protection.
- Load into Caulk Gun: Load the sealant cartridge into a standard caulking gun.

Troubleshooting
- Poor Adhesion: Ensure surfaces are clean, dry, and free of loose material. Roughen smooth surfaces if necessary.
- Sealant Not Curing: Verify application temperature is within the recommended range (40 to 100°F). High humidity can sometimes slow curing, but this product is designed for quick rain-readiness.
- Cracking/Peeling: Ensure proper surface preparation and application of a sufficient bead size. The product is designed for flexibility, but extreme movement or improper application can lead to issues.
- Uneven Bead: Practice applying the sealant on a scrap surface to achieve a consistent bead. Use a wet finger or tooling tool to smooth the bead immediately after application.
