OB1 Diamond Crystal Clear Universal Sealant & Adhesive - Hybrid Technology - ...

I recently tried out the OB1 Diamond Crystal Clear Universal Sealant & Adhesive, and I have to say, it’s an outstanding product that lives up to its promises. As someone who frequently tackles DIY projects, from sealing cracks around the house to doing some outdoor repairs, I’m always on the lookout for a high-quality adhesive and sealant. The OB1 Diamond Sealant has proven to be exactly what I needed, and then some.First off, the hybrid technology behind this sealant is incredibly impressive. It combines the best qualities of silicones and polyurethanes, offering the flexibility and strength of both. This means the sealant adheres strongly to a wide range of surfaces, including wood, metal, glass, and plastic, making it a versatile choice for many different types of repairs. I used it to seal gaps around my windows and doors, and it’s been incredibly effective at keeping drafts and moisture out.One of the standout features of the OB1 Diamond is its crystal-clear finish. Unlike some other sealants that leave visible marks or discoloration, this product dries completely transparent, which is perfect for areas where aesthetics matter. I used it on some visible spots around my patio, and the clean, clear look blends seamlessly with the surrounding surfaces—no unsightly blobs or residue.The UV resistance is another reason why I’m so impressed with this sealant. I’ve used products in the past that degraded or lost their effectiveness when exposed to sunlight, but the OB1 Diamond Sealant holds up well even under direct sun exposure. It stays intact, flexible, and clear, making it a reliable choice for both interior and exterior applications. Whether you're sealing something outside or indoors, this product can handle both with ease.Additionally, the sealant is water-resistant and weather-resistant, which is a game-changer for outdoor applications. I’ve had it exposed to rain a few times, and it has kept everything sealed without any issues. No peeling, cracking, or loosening, which makes me confident that this product will provide long-lasting protection.The 290ml tube is just the right size for most household or DIY projects. It applies smoothly, and I found it easy to control, even for more intricate jobs. The sealant is also quick-drying, which helps speed up any project I’m working on, and once it sets, it stays strong and flexible, allowing for some movement without compromising the seal.Overall, the OB1 Diamond Crystal Clear Sealant & Adhesive is a top-notch product that delivers exceptional performance across the board. Whether you're sealing, bonding, or repairing, its superior UV resistance, water and weatherproof properties, and clean finish make it a go-to solution for both indoor and outdoor tasks. I highly recommend it for anyone looking for a reliable, long-lasting sealant that does the job perfectly!

When it eventually arrived...I ordered this to seal my bath and to steady the wobbly taps before we went away for the weekend. So it was left to dry for 3 days.I ordered for delivery the day after. I waited in for it. It didn't arrive and I was going away the next day. I got a message from Amazon saying unable to deliver due to address. ( I have deliveries sometimes more than once a day). I contacted them they told me that they can reschedule for 2 days.I had to wait until I arrived back.Which defeated the whole object of having it delivered and done before we went away.Great stuff once it arrived though. Taps are nice and sturdy now and it's clear so it doesn't make a mess. I'm going to use this on lots of projects. It's very versatile. Adhesion is fantastic. Great value for money and very easy to use.

Bought as slightly cheaper alternative to CT1. Have also used Plumbers Gold in the past. I found this OB1 to be a less smooth than other brands, a bit jelly- like and more tricky to get a decent smooth bead. Seems to hold up pretty well though. Used to seal and waterproof shower waste trap, toilet connections, and an extremely heavy glass shower screen. Nothing has leaked or budged approx 3 months later so happy with how it works.

great stuff always buy

Easy to handle and apply. Excellent product. Seals very well. I have used before and will stick with this brand.

Goods received where past best before date

Easy to use and fixed the problem well

This sealant/adhesive excellent. It dries solid and it's over paint able. I used it for sealing concrete roof dry verge, it did the job
