Anthracite Multi-Surface Sealant & Adhesive, 290ml 2in1 formula

⭐⭐⭐⭐⭐ Outstanding Sealant and Adhesive – My Go-To for Professional UseThe 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 useThe 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.

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.

Haven’t used it before, it was recommended to me from a local trades person who uses it all the time.

Absolutely 100% amazing stuff. Did not let me down and know a shed staple, I always have some in stock. So versatile and in different colours.

This stuff is amazing, I've used it a number of times, used to stick brick slips ( tiles that look like bricks) along a patio edge to conceal the mortar from the lower level ~ been there for 9 years. This tube was to fix wood in the garden.

V/GOOD

Worst sealer I've used, doesn't tool very well at all.

High quality product. Professional grade. Strong adhesion properties but can be removed if needed. I used it in the automotive area to bond a metal bracket to glass.
