Troubleshooting
Sealant not dispensing smoothly
Ensure the nozzle tip is cut correctly and the inner seal is fully punctured. Check that the caulk gun is functioning properly.
Poor adhesion to a surface
Verify that the surface is clean, dry, and free from dust, oil, or other contaminants. Ensure the sealant is applied within its recommended temperature range.
Sealant is difficult to smooth
Attempt to smooth the bead immediately after application using a wet tool or finger. Wipe away excess with a damp cloth before it begins to skin over.
Sealant remains tacky after a long period
This could be due to a very thick application or high humidity. Ensure adequate ventilation and allow more time for curing. Refer to product specifications for estimated cure times.

Setup, Compatibility & Care
To use the OB1 Multi-Surface Construction Sealant & Adhesive, ensure you have a standard caulk gun. Cut the nozzle tip at a 45-degree angle to achieve the desired bead size.

Compatibility is broad, adhering to materials like wood, metal, concrete, brick, glass, and most plastics. After application, smooth the bead with a wet tool or finger, and wipe away excess immediately with a damp cloth. Clean tools with water before the sealant cures.
