Sorry. **Q: Can this foam be painted or stained to lighten the color when used on a light colored rock waterfall? Does it come in any other color?** A: I hope you like black..... it seems to come in only one color and I very much doubt it can be painted and stay that way. You might consider a stain when it is still wet and mixed in.... but that sounds like a very sloppy endeavor. **Q: What can I use to clean this off of my hands?** A: Hello Troy, Instructions advise wearing gloves for protection from the product. Taken from the SDS... P262- Do not get in eyes, on skin, or on clothing. P264- Wash hands and other skin areas exposed to material thoroughly after handling P302+P352+P333+P313 IF ON SKIN: Wash with plenty of soap and water. If skin irritation or rash occurs: Get medical attention In case of contact, immediately flush skin with plenty of soap and water. Foam will stick to skin, gently wipe product from skin with a damp cloth and wash with plenty of soap and water. Remove contaminated clothing and shoes. Wash clothing before reuse. Call a physician if irritation persists. I hope this is helpful! Dana at Practical Garden Ponds, Ext.1 **Q: Does the surface have to be dry before application?** A: Works best on moist surfaces that have been rinsed clean of dirt and debris. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Made me look like a pro. *by on Reviewed in the United States October 10, 2025* 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 product *by on Reviewed in the United States January 17, 2026* Great use for a DIYer! Did any AWESOME job sealing the stones in for our pond ### ⭐⭐⭐⭐ Repeat customer, but use flexible disposable gloves that won't tear and suggest super glue for... *by on Reviewed in the United States May 19, 2019* 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. ## Frequently Bought Together - Aquascape PRO Professional Black Foam Sealant for Pond and Waterfall, Installation Tools, 24-Ounces |30096, 24-Ounce - Aquascape Foam Gun Applicator for Pond, Waterfall, & Water Features | 54003 - Aquascape Professional Foam Gun Cleaner for Pond, Waterfall, and Water Features, 12-Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/71234655-aquascape-professional-black-waterfall-foam-sealant-for-streams-and-waterfalls](https://www.desertcart.us/products/71234655-aquascape-professional-black-waterfall-foam-sealant-for-streams-and-waterfalls) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-05*
