Easy Pro Black Waterfall Foam – Ready to use – 20 oz
Control Water Flow and Perfect Your Waterfall Design
Take control of your waterfall's water flow with EasyPro Black Waterfall Foam. This professional-grade, ready-to-use foam fills cracks and gaps between rocks to prevent water loss and direct flow exactly where you want it, creating dramatic cascades and sheets of water.
The black color disappears into rock shadows for a natural appearance, while the minimal-expanding formula fills precisely without pushing rocks out of position or requiring excessive trimming.
Patented Reusable Trigger System
Unlike traditional one-use foam cans, the patented trigger system allows reuse for two to three weeks after opening. Work at your own pace, make adjustments as needed, and tackle multiple projects without rushing. The precision trigger dispenses foam in any position—upright, sideways, or upside down—perfect for reaching tight spaces between rocks.

Frequently Asked Questions
How long does the foam take to cure?
The foam skins over in 10-15 minutes and fully cures within 24 hours. Avoid disturbing it during the curing process.
Can I use this foam underwater?
No, apply to dry surfaces only. Temporarily shut off water flow, allow surfaces to dry, apply foam, let it fully cure, then restart water flow.
What makes this different from regular expanding foam?
This is specifically formulated for waterfalls with minimal expansion to prevent rock displacement, black color for natural appearance, fish-safe ingredients, and a reusable trigger system that lasts 2-3 weeks.
How much area will one can cover?
A 20 oz can typically handles multiple small to medium gaps in a standard residential waterfall. The minimal-expanding formula means you'll use less foam per gap compared to standard foams.
How should I store the can between uses?
Store upright in a cool, dry place away from direct sunlight and heat. Clean the trigger nozzle after each use. The can remains usable for 2-3 weeks after first use.
Can I trim the foam after it cures?
Yes, once fully cured, the foam can be trimmed with a sharp knife if needed. However, the minimal-expanding formula typically requires little to no trimming.
