Superfish Scaping Foam 375ml Black Expanding Foam

Brilliant product

Just buy it works very well

Knocked a star off as this stuff is so expensive but it does work well. If your rocks aren't dusty/dirty (we ran a hose over ours first and then left to dry in the sun) it sticks brilliantly, and the areas that we squashed down once it skinned over (to poke back inside cracks in the stone if it expanded out a bit too far) have set like rock themselves. Brilliant stuff to get water to flow where you want it to on waterfalls but like all expanding foam you can get in a mess if you aren't careful....especially if using this with light stone like we were but it's not too bad and worth the effort. You can also push gravel/stones into it to help disguise it if it oozes out a little.

In principle this is great - a black foam - some jobs require nothing less! However … we are in n can No.3. They quickly expire! Can 1 was great but short lived. Can 2 arrived without the all important nozzle & applicator (since refunded) & can 3 has proved so hard to apply, it has she foam all over our fireplace and wall (funny as I type but believe me the mess is on another scale) & requires tremendous strength to force! Time will tell whether or not the Eureka find of Black Foam is indeed a good thing!

Nozzle kept blocking and needed to be cleaned every time you pressed it. Then the can nozzle also gave up and ended up throwing the half full can in the bin. A 5min job turned into 3/4 of a hour.

Made barely any foam and had to buy several more for cheaper of a different brand. Didn't go very far for the size of the can

I like using this brand because it takes the guess work out of using other brands in conditions where it'll be in regular contact with animals, aquatic or otherwise A little pricier, but it's works like any other expanding foam!

Product nozzle blocked after only using half the foam, so half is wasted
