Not happy that I was delivered a sealant that is two weeks away from it's expiry date!

This is great stuff I've never heard or seen this product before i needed something for outside and the internet recommended this. I have a black outdoor junction box that was leaking in the seal originally used was coming away from the wall ideally needed to replace the box but i have that weird pebbledash insulation stuff so a nightmare to screw into hence why i got this product to seal the back of the box onto the wall and a coat around the front cap to seal it from water.

What can one say about a tube of sealant? Does it seal? Yes.

The price is good and delivery was quick. The sealant tube is as easy to use as any other sealant tube (though you'll need to provide your own nozzle). Adhesion is good but not great, so you can get some stray blobs, and with the black dye those blobs can soon make your clothes a mess... be careful out there!

Very sticky, need to let it go off to try and clean any off, so far so good
