Know before you buy
Yes, this product requires a professional foam gun for application. The gun allows for precise control when filling gaps between rocks and liners, which is difficult to achieve with standard aerosol nozzles.
The foam is specifically formulated in black to blend into the shadows of your water feature. Once cured and covered with rocks or gravel, it remains largely hidden, ensuring a natural look.
By expanding to fill voids behind and between rocks, the foam creates a physical barrier that forces water to flow over the stones rather than leaking behind them. This ensures your waterfall maintains its intended design and volume.
Yes, once fully cured, the Aquascape Professional Waterfall Sealant Foam is non-toxic and safe for use in ponds containing fish and plants.
Each 24oz can is high-yield, designed to provide extensive coverage for typical residential waterfall projects. The exact amount depends on the size of the gaps you are filling, but it is engineered to handle professional-scale installations.
This foam is excellent for sealing gaps in waterfalls and streams where water is escaping the intended path. However, it is not a patch for punctures in the pond liner itself; those require a dedicated liner repair kit.
