OB1 Terracota Multi-Surface Construction Sealant & Adhesive, 290ml

⭐⭐⭐⭐⭐ 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.

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.

I used this to re-seal my shower which was sealed from new less than a year ago. The silicone used was an expensive brand and colour matched to the grout, but this had started to show signs of deteriorating, and pealing at some of the corners and at random points. Rather than neglect the issues and to have problems with potential leaks, I stripped the entire seal off using multi solve and a scalpol knifeset and a silicone remover set. Once the surface was clean and degreased I applied the OB1. It is more difficult to apply than standard silicone as it's a thicker formula and does not spread well as silicone. But once smoothed through using a silicone smoothing tool it looked very nice. The finish is not smooth as you'd get from silicone but you don't get pinholes and the finished product is alot more durable. It feels like hard rubber as unlike silicone which feels spongy and soft. I've even went over the ob1 seal again once the first cost had dried out by an extra 2mm 8mm in total. I left the OB1 to dry out for 4 days before using the shower to ensure 100% curing of the seal. With OB1 I'm really confident that there won't ever be a situation of it pealing shrinking cracking or even letter water through

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.

Great quality, perfect dark brown colour. We have dark wood panels on the kitchen ceiling with spotlights. There was a tiny gap between the two of panels which the light was coming through that gap and didn’t look nice so I wanted to fill that gap. This brown sealant was perfect , exact brown colour i was looking for ,went on so smoothly and has no smell. Very happy with my purchase.

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.
