Aquascape Professional Black Waterfall Foam Sealant for Streams and Waterfalls, Fills Gaps Between Rock and Boulder to Direct Flow, Fast Drying Polyurethane Expanding Foam, 30096

I purchased the gun that’s used for the product and it worked perfectly. The product never dried out inside the canister as long as I kept the gun tilted in the right direction. I got to use the full canister over a few days without premature drying as other canisters will do. There was tons more foam in the pro pack than in the regular cans that are cheaper. Absolutely the best price is to purchase this canister for a big job.

Great use for a DIYer! Did any AWESOME job sealing the stones in for our pond

Repeat customer, but there is a packaging design flaw. You'll find that the nozzle easily unscrews while in use no matter how tightly the nozzle it's screwed on, which creates a big mess. If this design flaw was corrected, it's rating is a 5 out of 5...100%. Started to carefully super glue the screw on nozzle and plastic tube before using and this made a huge improvement.The foam sealant itself is excellent. However, suggest always wearing flexible disposable gloves when using it. It's too easy to get busy trying to efficiently use all of the product which means the foam will almost 100% cute (completely dry) on your hands. If this happens anywhere on your skin, resist the urge to immediately remove it and let it first dry completely. Best advice if you do get it on your skin and can't pick it all of after it dries is patience... while soaking in the tub picking away at the foam. First 24 hours is bad removing only around 50% while working hard at it. Have personally never had it remain on my skin for over 72 hours, since the oil from your skin will start loosening it.Suggest always using up each can before stopping, since the product plugs up the nozzle and even after cleaning out the blockage; the aerosol is not powerful later to expel the foam.

I purchased the professional gun to go with this as opposed to getting the can's which have the tube dispenser. Could not be happier. Worked perfectly, stayed good in the gun for nearly a month before I cleaned it out and it was flawless. I was concerned I would need more than one can for my project. As it turned out I still have over half a can remaining.

The product works very well and I used an applicator gun and the recommended cleaner. The cleaner will clean the gun, but NOT your skin. If this stuff dries on your skin, you'll be very sorry. I tried nail polish remover, gasoline, Goof Off, cooking oil and baking soda, and soap and water to no avail. I finally soaked my hand in warm water until it got wrinkled and then scrubbed it off with one of those green scratch pads, along with the skin I suppose. And then my hands still smelled like gasoline.... Lesson learned the hard way.

If you're going to build a waterfall or pond, this product is what basically holds the project together. You literally can't install any kind of water feature without it. It dries fairly quickly and expands to about 1.5 the size after applied. The only thing I don't like about it is that if you get it on your hands, it's very hard to remove, but it's just part of the job.

Holy crap this can goes far. I know the price is rough, but this one can is the equivalents of can after can of the other brands. It's easier to use too. I had some off-brand foams shrink on me instead of expanding. No problems with this foam.

Has worked fine on my pool waterfall and is still holding up so far.

Really easy to apply foam using the applicator gun. Love that this stuff comes out very controlled and not at 6 million km's a second. It also expands nicely to fill the gaps but not so much that it goes everywhere (have used others in the past and they expand way too much). Give it 15 minutes and you can manipulate the skin and mold it to your requirements. After an hour you can cut it with a knife to remove and excess if needed. Would definately buy again.

Product works great, but very messy. Be prepared before you open. Work fast and the results will be great.

The color of the spray foam is black and it cures quickly, 15 mins. It does take up all the spaces in the stone area of the pond and does hold little stones pressed in the foam as it cures. The spray foam does take the space fully as applied. The only draw back is you need to have the spray foam gun to apply the can of spray foam has to screw into spray foam gun.

I have a small pond (900 gallons) and noticed some of the spray foam used by the installers had shrunk or washed away. Bought a can of the Aquascape foam to fill in and seal the gaps that had formed and worked like a charm. Little hard to get used to at first but once you figure out the expansion properties it was pretty easy to use. Remember to shake the can before use and wear gloves cause it’s messy. Once applied you can mould the foam after 5-10 minutes if necessary. So pleased that my next purchase will be the gum and foam.

I use the foam to fill in cracks and to direct water flow in my 2 waterfalls. The foam expands and fills in any cracks between rocks and crevices preventing water from flowing between the cracks. It comes out rather quickly so you need to be ready. Also, wear gloves. If you get it on your skin it makes a mess and does not come off with soap and water, must use finger nail remover or something. After applying, I let sit overnight and then using an exacto knife, I cut away all the pieces I don't want showing. Works fantastic.
