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.

I bought this for a seal i needed around a black wooden outdoor unit, where I had some gaps from a pipe I had going through it. It sealed easily and was black to match the unit etc. Went off fairly fast and has remained ever since doing its job - Sealing. Cheap, easy to use and very effective. A1 Product

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!
