Anthracite Grey Construction Sealant & Adhesive All-In-One Hybrid Polymer | Superior to Silicone Sealant | Waterproof, Odourless, Anti-Mould, Paintable | Kitchen Bathroom Outdoor - 300 ml 3 Pack

Plugged the hole i needed it for. Waterproof and hasnt leaked so i assume its good quality and durable. Straightforward to use simply insert into silicone gun and snip the end off. Colour is indeed jetblack.

The sealant performed well in joining a flexible perforated 100mm drain to a soil pipe. One application with no leakage. Washes off hands or clothing immediately after use if spilt. Like others have noted the use by date was only 2 months after purchase.

Good stuff, stays a bit tacky for a while. Best to line each side of the gap to be filled, if possible, with masking tape. Remove the tape after you filled and levelled it or the tape might stick to the filled edge.

Excellent product, tough and long lasting

Easy to use, goes on great and drys quite quickly.

I'm sure this sealant works - but getting it out of the tube is an issue ! The stock was manufactured in March 2024 and may therefore be a bit old, but even with the nozzle cut to give a thick bead I had to use both hands on the steel dispenses to get anything out. I will try it with my cordless caulking gun to see if that can extract it without bursting the tube. Disappointing.

Don't very often use sealant but this went on a treat and looks good

Good product excelent service reasonable priced.

This product did better than expected.

Worked fantastic, used for gluing together flowers made from upcycled glass and dishes. Held all pieces together thru rain and high humidity. Have not tested thru the winter months yet. Live that it dries clear and easy to apply. Let dry indoors for 48 hours before hanging outside.

The product worked flawlessly, and I would highly recommend it. As for the Amazon delivery time, the product was late arriving. This is becoming more and more of an issue with Amazon. I've been with Amazon prime for 20 years and over the past several months, delivery times have typically all been later than told at time of order. Likely due to Amazon using the USPS more frequently.

Just put it in my chicken coop. So far it’s great! I’ll update if it doesn’t hold up but I foresee it lasting. Also painted over it and it was seamless. I actually really like the grey colored one because it’s way easier to work with and see.
