GREAT STUFF 99112849 Smart Dispenser Pond & Stone, 12 oz, Black

Muy rendidor, fácil de aplicar

Really good but horrendously overpriced

I have been using aquarium cement for putting rocks together for my reef aquarium but it was always a pain and it didn't really hold well together. This foam is completely different beast. It holds the rocks to get us so well you can grab it by one of the rocks and everything else stays securely attached to it. The strength is much better than the usual insulation foam in the spray can you can buy at Lowe's. The yellow kind. A strong word of warning though, this black foam is really nothing like the usual yellow one. When you work with it, absolutely use disposable gloves because this thing sticks to your skin so well that it's took me more than a week to get it rid off my skin. And it's more that my old skin just peel off after a week, not that the foam would peel off the skin. On the other hand it's the testament how well this thing sticks. Which also means you don't have to use too much of it on the rock. It will expand quite a bit and if you put too much it will just get out everywhere. EDIT: I have the structures in my tank for almost a year and everything holds still like the first day. Moreover, Even tho the nozzle dried, I removed it and put there another one from normal foam can and it still worked almost a year later! I glued 5 towers (4-6 stones, 16-20" tall) and about 10 smaller structures and there is still some left in the can.

海外のビバリウム制作動画を見て購入。 類似商品と比べたら、高いけど、国内製の黒色発泡ウレタンを探すことができなかったため、満足して使いました。 ただ、ウレタンの出力が均等ではなく向きによったりする傾向が強い。

El funcionamiento es bastante raro para sacar la espuma veces se escapa mucho aire y no tira espuma no se infla tanto y aparte tiene poco contenido Cabe destacar que he usado muchas espumas no es la primera vez
