Houyi Expanding Foam
Houyi Expanding Foam is a high-performance material designed specifically for ecological landscaping, aquascaping, and terrarium building. Once applied, the foam expands and cures using moisture from the air, creating a durable and natural-looking structure.
Equipped with a convenient plastic adapter, it ensures precise application, making scaping easier and giving you greater control over your design. Simply shake well and spray—the foam hardens quickly, saving you time while providing excellent results.
✔ Safe for aquariums, vivariums, terrariums, livestock, and plants
✔ Strong adhesion on a wide range of surfaces including uPVC, masonry, brick, block work, glass, steel, aluminium, and timber (not suitable for PP, PE, or Teflon)
✔ Eco-conscious – contains CFC-free propellants that are harmless to the ozone layer
Available in two natural colours: Black and Brown.
Perfect for building rock walls, securing hardscape, creating custom backgrounds, or shaping natural habitats.
