Black Mamba FHG High Tack - Superfast Mono Component Polymer Sealant Cartridge - Gray, Single, Grey

After watching youtube video about this product, I bought it for installing a under-counter sink. The process is really easy and it worked great. I only wish there is a better way to seal the tube so that the remaining sealant can be used for later project.

really a great product. watched it on you tube for resetting a bathroom sink, and it worked great

It's been a few months and holding strong. Made sink installation super easy. I guess time will tell for sure, but so far so good.

Black Mamba Polymer Sealant is incredible! Our undermount bathroom sink fell down (fortunately into my hands). My husband read about Black Mamba and decided to give it a try. The directions say the sink will hold after about 15 seconds. We were skeptical, but that was the truth! Once in place, he needed to move it just a bit to one side and it could be done but it was hard. He also clamped a 2 x 4 across the granite and down through the drain to hold the sink in place for 24 hours just in case it needed extra support. Dispensing the Black Mamba through the caulk gun was difficult because so much pressure is needed. By the time he had applied the bead of Black Mamba around the sink lip and finished installation, the caulk gun was adhered to the bottom of the tube of Black Mamba. Unfortunately, he had to trash the caulk gun. However, he saved us a ton of money by doing this project himself. Highly recommend Black Mamba!

Great glue

We ordered two tubes 10/2024 for a sink installation. I didn't think to look at the date on the tube. It was 03/2023, seven months past a shelf life of one year. It went on thick and didn't compress like it should. I'm out of time and money. Might be a great product if used before the shelf life.

I was concerned about other reviews that said you needed a special caulk gun. Well I put the tube in the sun for 15-minutes or so, until it was warm and it came out just fine. The sink is mounted, hasn't fallen off yet!It is rather thick. I'd probably put on a narrower bead in the future.

If you follow the directions/videos on how to use it works as advertised. Some of the reviews said it was difficult to get the adhesive out. We used a higher end caulk gun that we got at home depot and it qorked just fine. I would highly recommend.
