Beckett Corporation Waterfall Foam Sealant

This stuff really works. My waterfall was reduced to a watertrickle so I decided to try this product. My last experience with foam was not a happy one because i didn't follow directions. My advice...Read the directions very carefully; it is extremely easy to use but be aware that you don't want to get it on your hands because the stickly result will end your working session. the other advice is be aware that it swells to three times the amount you put in and begins to swell almost immediately, so don't overdo it. I pressed small pebbles into it as I put the foam down to help make it look more natural. Also, the immediate resulting color is a purple black which was not very attractive. I was going to paint it however lucky for me I never got time to do it. Three weeks later and it looks like the rocks around it...A grayish green...So just wait a few weeks and you will be very happy with the resulting color.

This product works great but be sure to wear gloves and clothes you don’t mind ruining. No matter how careful I was, it managed to get everywhere. This stuff expands like mad so start small and add on if you need to.

I’ve used this product many times on my pond and waterfalls and it works very well. As mentioned by other reviewers you need to have everything ready. The foam dries fast and isn’t easy to spread. It really expands so be careful when spraying. Wear chemical resistant gloves. If it gets on your hands it is tough to remove even with acetone. The worst feature is the spray nozzle. It is very flimsy. The trigger and tube are one piece. The instructions say that the product can be stored and reused by cutting the tube. I’ve had no success with this. The foam sets in the tube. Consider the can as single use regardless of how much foam was actually used. It might help if extra spray nozzles were provided.

Excellent product. I needed to create a moss wall and platform for my best terrarium. I built the frames than filled this in my 20 gallon. Turned out great. Perfectly safe to use for animals.

I bought this foam sealant to patch up previously foamed areas in my waterfall that were in need of repair. Before using I had turned the waterfall off and let the old seals dry out, cut away seals that were decayed -- in other words did a lot of prep work. I gave this product three stars because it's an average good product. What I found in using this product was the following: 1) filling in cracks where some of the old product is still present is not advisable. This sealant for what ever reason did not form a nice adhesion to the old seals. 2) this product as mentioned in the directions (which by the way the font on the can needs to be enlarged so one does not need to take out a magnifying glass to read them) does expand tremendously. After using to fill in a crack or two, you will get the hang of how much to apply. 3) trimming the foam was easy and it tended to cut cleanly. I used an utility knife and hacksaw blade. However, what you will notice is that due to the nature of the foam, there are little air pockets that get exposed. This is not a problem for me, but beware if you are looking for a very smooth finished surface. 4) as I was trimming the foam in a side wall crack (where one rock is on the bottom and the other rock makes the side wall), the foam adhesion to the side wall rock was poor. In fact, in most cases I know there is not a good bond. This could be because I did not mold the foam right after applying but rather relied on the foams natural expansion to do so -- lesson learned. 5), the foam color is a deep purple even after letting it dry over night. So if you are looking for a true black, beware of this. 6) I was surprised how quickly the can emptied. I have a fairly small four tier water fall and reading how much the product should cover and the nature of my repairs, I truly expected one can to do the job. However, that was not the case. Hope this all helps.

Great stuff. Solves lots of problems. Doesn't kill fish...i accidently got quite a lot into the pond water (I immediately flushed some fresh water in) We don't like to permanently install something in case we need to move it later and this stuff is removable yet completely blocks water seepage.

Holds the liner under the rocks in a waterfall.

Used it to put in a hole in a tree to keep water from going in it
