Does the terracotta colour match standard bricks?

Troubleshooting
Sealant not dispensing from the tube
Ensure the sealant gun is properly engaged with the tube and the release trigger is being pressed firmly. Check that the nozzle tip has been cut and the inner seal (if present) has been punctured.
Poor adhesion to a surface
Verify that the surface was clean, dry, and free from dust, grease, or previous coatings. Re-apply after thoroughly cleaning the surface and consider using a primer on porous materials.
Sealant is stringy or difficult to apply smoothly
Ensure the product has not exceeded its shelf life. For very cold conditions, allowing the tube to warm to room temperature may improve workability. Smooth the bead immediately after application.
Sealant does not cure or remains tacky
This may occur if applied too thickly or in conditions with very high humidity or low temperatures. Ensure application is within recommended temperature ranges and thickness. Allow adequate curing time in appropriate conditions.

Setup, Compatibility & Care
Setup: This sealant is applied using a standard sealant gun. Ensure the sealant gun is correctly loaded with the 290ml tube. Cut the nozzle tip at a suitable angle for the desired bead size, typically a 45-degree angle. Puncture the inner seal if present.
Compatibility: The OB1 sealant offers strong adhesion to a wide range of common building materials including concrete, brick, plaster, wood, metal, glass, and many plastics. Always test adhesion on a small, inconspicuous area of the material first, especially with painted or plastic surfaces, to ensure compatibility and prevent damage.
Surface Preparation: For optimal adhesion, ensure surfaces are clean, dry, and free from dust, grease, and any loose material. For porous surfaces, a primer may be beneficial. Apply the sealant evenly to the gap or joint, then smooth the bead immediately using a damp cloth or a smoothing tool before it begins to skin over.
Care: Once cured, the sealant is waterproof and weatherproof. Clean any accidental spills or excess material promptly with a damp cloth before the product cures. Cured material may be difficult to remove. Store unused tubes in a cool, dry place.
