Pond & Stone Black Foam Adhesive Sealant, Straw Use 12 oz

Kraken Bond Pond & Stone Adhesive Sealant (SF 403) is a low-expansion black polyurethane foam made for pond, waterfall, and landscape projects. It fills, seals, and bonds gaps, joints, cracks, and voids between rocks, stone, and other outdoor materials. Its controlled expansion helps direct water flow over the rocks for a clean, natural finish, and the cured foam is water- and mold-resistant. Fish & plant safe. Comes with an applicator straw for precise placement.

How to Use

• Surface Prep: Make sure surfaces are clean and free of dust, grease, and loose particles. Lightly moisten porous surfaces such as brick, concrete, limestone, and masonry.
• Can Prep: Keep the can at room temperature for at least 12 hours before use (ideal can temperature is 68°F / 20°C). Shake vigorously for at least 30 seconds.
• Application: Screw the applicator straw onto the can and dispense upside down. Apply carefully, leaving room for expansion, and do not overfill. Apply between 21°F and 86°F (-6°C to 30°C).
• Finishing: Trim cured foam if needed. Protect cured foam from prolonged direct sunlight; covering or coating it improves outdoor performance.
• Cleanup: Clean uncured foam with Kraken Bond Foam Cleaner. Cured foam can only be removed mechanically.
• Safety: Use in a well-ventilated area and wear appropriate protective equipment. Keep away from heat, sparks, and open flames. Do not pierce or burn the can, even after use. Keep out of reach of children.
