Product Information
Full details
This OB1 clear construction sealant is for trade professionals and DIY enthusiasts undertaking construction, maintenance, and repair work. Its key benefit is providing strong adhesion across multiple surfaces with a waterproof and weatherproof finish for both interior and exterior applications. A potential caveat is the clear finish, which, while versatile, might not be suitable for all aesthetic requirements if a specific colour match is needed beyond transparency. It functions as a sealant, adhesive, and filler, offering dependable performance for sealing joints, fixing materials, and general installation jobs.

FAQs
Is this sealant paintable?
Once fully cured, the OB1 clear sealant can generally be painted over. It is advisable to test compatibility with your chosen paint on a small area first.
What is the shelf life of the product?
Unopened tubes stored correctly in a cool, dry place typically have a shelf life of 12-18 months. Refer to product packaging for specific dates.
Can this be used for structural bonding?
This product is designed for sealing, bonding, and filling in construction and repair tasks. For critical structural bonding, always consult product specifications or seek professional advice.
How long does it take to cure?
Drying and curing times vary depending on bead size, temperature, and humidity. A surface dry may occur within minutes, but full cure can take 24-48 hours or longer.
Can I use this in a very wet environment like a shower?
Yes, its waterproof and weatherproof formula makes it suitable for sealing joints and gaps in bathrooms and kitchens to prevent water ingress.
Does the clear sealant yellow over time?
The formulation is designed for durability. While some clear sealants can yellow over extended periods in direct UV exposure, OB1 aims for long-lasting clarity. For critical aesthetic applications, consider testing or consulting the manufacturer.
Troubleshooting
Sealant not extruding from the tube
Ensure the inner seal has been properly punctured and that the sealant gun is functioning correctly. Check for any blockages in the nozzle.
Poor adhesion to surface
Verify that the surface was clean, dry, and free from contaminants before application. Ensure proper application technique and adequate coverage.
Sealant remains tacky after application
This can occur in very humid or cold conditions. Ensure application within the recommended temperature and humidity ranges. Allow additional curing time if necessary.
Uneven bead application
Practice with a sealant gun on scrap material. Ensure consistent pressure and movement. Adjust nozzle opening for desired bead size.
