Troubleshooting
Poor adhesion to the surface.
Ensure the surface is clean, dry, and free of contaminants. Lightly abrading non-porous surfaces can improve adhesion.
Sealant not curing properly.
Check the expiration date of the product. Ensure the application is within the recommended temperature and humidity range. If applying in cold conditions, allow more time to cure.
Sealant shrinking or cracking after curing.
Ensure that the sealant is applied in the correct bead size and depth. Make sure the surface is not moving excessively. OB1's formulation resists shrinking, but movement can affect the seal.
Difficult to apply.
Use a quality cartridge gun. Cut the nozzle at a suitable angle and size for your application. If the sealant is too thick, try warming it slightly before application (ensure it remains within the recommended temperature range).

Setup, Compatibility & Care
Surface Preparation: Ensure surfaces are clean, dry, and free from loose particles, dust, oil, or grease. For non-porous surfaces, lightly abrade them for better adhesion.
Application: Cut the nozzle to the desired bead size. Apply the sealant using a standard cartridge gun. Ensure complete coverage of the joint or surface.
Tooling: Smooth the sealant with a spatula or your finger (dipped in soapy water for a smoother finish) within 10-15 minutes of application.
Curing: Allow the sealant to cure completely, following the manufacturer's instructions. Curing time may vary depending on environmental conditions.
Compatibility: OB1 is compatible with a wide range of materials. However, always test on a small, inconspicuous area first, especially with sensitive materials.
Care: Once cured, the sealant is generally maintenance-free. Clean with a damp cloth and mild detergent. Avoid abrasive cleaners or solvents.
