Review: ⭐⭐⭐⭐⭐ Professional-Grade Sealant and Adhesive That Never Lets Me Down - ⭐⭐⭐⭐⭐ Outstanding Sealant and Adhesive – My Go-To for Professional Use The OB1 Seal & Adhesive Black 290ml is one of the best all-round sealants and adhesives I’ve used. As a professional tradesperson, I need products that are reliable, easy to apply and built to last, and OB1 consistently delivers. It has excellent initial grab and bonds extremely well to a wide range of materials, even in situations where other products can struggle. The finish is neat, it tools nicely, and it cures to a strong yet flexible seal that stands up well to movement, moisture and changing weather conditions. One of the biggest advantages is its versatility. Whether I’m sealing, bonding or carrying out repairs, it’s often the first product I reach for. It also adheres well to slightly damp surfaces, making it particularly useful for emergency repairs. Pros: * Excellent bonding strength * Strong initial grab * Flexible, durable finish * Suitable for a wide range of materials * Performs well indoors and outdoors * Easy to apply and tool * Trusted for professional use The only minor downside is that, like most high-performance adhesives, it can be a little messy if you don’t apply it carefully. Taking your time gives a very clean, professional finish. Overall, this is an exceptional sealant and adhesive that has earned a permanent place in my van. Reliable, versatile and built to last—I’d highly recommend it to both professionals and DIY users.
Review: good colour match for my windows trims - The anthracite colour is a spot-on match for modern grey trim, and it doesn't shrink or crack like some cheaper sealants do over time. It gives a really neat, professional finish and holds tight straight away, even if the surface is a bit damp when you apply it. It’s easily the most reliable thing I’ve used for sealing up gaps.
