• Product can be sanded to remove rough edges and allow for refinement and smooth finishes.
• Bonds dissimilar substrates including concrete, masonry, ceramic, wood and metal - eliminating the need for multiple applications with additional products.
• Ideal for minor repairs on building construction, walkways, stairways, pools, decks, patios, and general maintenance and repair.

Product Description ------------------- 3M Concrete Repair Self Leveling is a fast-curing polyurethane adhesive designed to repair cracks, spalls and breaks in concrete floors and horizontal concrete surfaces. Self-leveling repair material applies with a common caulk and flows freely into horizontal repair areas. It hardens in as little as five minutes and allows for sanding and refinement in 15 minutes, eliminating downtime. From the Manufacturer --------------------- The versatility of the 3M Scotch-Weld Concrete Repair 600 repair system makes it ideal for repairing cracks and spalls in concrete and masonry, pool decks and patios, custom tapping of bolts and screws into a variety of substrates, and setting anchors in horizontal surfaces. The two-part adhesive bonds through a reaction that cures to any depth without cracking. And once mixed our formula resists weathering, expansion and contraction. This product is gray in color, and may also be sanded to eliminate rough edges, for refinement, or to provide a smoother finish. Recommended Applications * Re-installing posts and rails * Light duty custom threading and anchoring * Tough, non-brittle bonding of wood, metal, glass and plastic * Bonding of dissimilar substrates * Non-brittle bonding to primed PVC and to ABS pipe 3M Scotch-Weld Concrete Repair 600 is a two-part component system. The Duo-Pak cartridge keeps the two components separate until ready for mixing to maximize working time. With the squeeze of a trigger the components are automatically mixed with our innovative mixing nozzle and easily dispensed precisely where needed without an unwanted mess. The bubble-free liquid begins curing immediately while also self-leveling to create a tough, non-brittle bond. The fast curing adhesive formula provides a one minute work life. What Are Urethane Adhesives? Two part urethane adhesives cure ly, rather than relying on moisture from the air. Because of this, they can cure quickly with no depth of cure issues in contrast to one-part urethane adhesive sealants. Urethane adhesives will bond most common materials such as wood, metals, rubbers, cured epoxy, leather, tile and glass, many plastics, concrete and more. The versatility of urethane adhesives is exhibited in the different formulations that have varying cured properties such as different levels of stiffness and flexibility, open time and cure speed, and hardness. They can cure to a relatively rigid or flexible state to meet a wide range of requirements. In either finished state, urethane adhesives will maintain bond strength integrity through variable environmental factors such as temperature, moisture and exposure.
