Dap 12 oz. Touch 'n Foam Landscape Exterior Filler Adhesive. Touch 'n Foam Landscape Filler-Adhesive is a black colored foam formulated to retain its dispensed color. Blends naturally into the surrounding landscape, even when exposed to direct sunlight. It bonds quickly to porous or non-porous rock, stone, cement, wood and cloth and is ideal for replacing loose mortar in rock walls. Touch 'n Foam Landscape can also be used to direct water flow in pond or waterfall applications. Black foam is UV resistant. Won't discolor like conventional foam no painting needed. Expands to fill gaps and voids, easier and less expensive than mortar. It's safe for use around fish or plants. Fills holes in trees to seal out pests. Use as a craft foam for artificial plants.
