Ditching traditional, messy mortar for your rockery has never been easier. AquaForte Landscaping Foam is a specialised polyurethane foam formulated specifically for demanding pond and waterfall construction. Unlike standard DIY sealants, this superior adhesive features a unique UV-resistant formula that prevents discolouration or an unsightly yellow tint when exposed to direct sunlight. Curing to a subtle dark grey, it easily blends into natural stone and shadows, seamlessly blending into your garden landscape. By effectively expanding to seal cavities and secure heavy rocks into place, it is the ultimate tool for professional landscapers and water garden enthusiasts. How to Apply AquaForte Landscaping Foam Preparation: Ensure your application surface is free of excess moisture, and do not use the product while it is raining. For the absolute best results, process the foam in temperatures between 16°C and 38°C. Application: Screw the applicator trigger assembly securely onto the valve, then shake the can well for at least 30 seconds. Hold the can completely upside down and slowly squeeze the trigger to dispense the foam into the desired area. Expansion & Curing: Because the landscaping foam expands significantly, you only need to fill the void about one-third (1/3) full, leaving plenty of room for it to swell into the crevices. The foam will be tack-free in about 30 minutes and fully cured and ready for water flow in 4 hours. Is this foam safe for my fish and aquatic plants? Yes. AquaForte Landscaping Foam is specifically designed for aquatic environments. Once the foam has fully cured, it becomes completely inert and non-toxic, making it 100% safe for all pond fish, plants, and surrounding wildlife.
