Rated 5 out of 5 by from OB1 adhesive Used this to fit wood battens to create a panelled wall effect. Only had to use 1 nail and that was due to the wood being warped. The OB1 worked superbly, thankfully I will not have to take it off in the future.

Rated 2 out of 5 by from OB1 overprint does not dry. Sadly I can not recommend this product. I had previously purchased EBT and used it to seal outside of a large steel box. I had applied EBT but as soon as I put red oxide primer on it never dried...I was sold it as paintable. However it wasn't. So I took it back and fair enough screwfix replaced it with a hybrid OB1. BUT after drying completely and then painting over with red oxide whilst the red oxide dried this time, allowing a week for it all to cure. When I painted over with Tractol 318 (tekaloid) and whilst that was dry everywhere within 24 hours , any part that had OB1 under it had wet top topcoat that stayed sticky to this day. Disappointed..

Rated 5 out of 5 by from A good all rounder Got a few tubes for patching roof tiles and got a good hold on some less than ideal surfaces

Rated 1 out of 5 by from It turned Green! I was convinced by a rep to change from a similar brand to using this as it was the same but slightly cheaper. What a mistake! It’s properties as an adhesive we’re good enough and sealed fine but was called back to the customers address after just a few weeks as it had turned green! It was then a nightmare to remove!

Can this be used to seal between a PVC window and the surrounding brickwork ? What gun size would you recommend? Thanks

Asked by: DIYRedAlert

Can this be used on natural stone or will it leach into the stone and cause staining in the way that silicone does?
