3M™ Scotch-Weld™ Concrete Repair 600 is a quick-curing, two-component polyurethane adhesive designed to repair cracks, spalls and breaks in concrete, masonry and stone. Our rapid setting concrete hardens in as little as five minutes, eliminating down time without lengthy disruptions to day-to-day services. In fifteen minutes the bond is strong enough that you can drive a forklift over it.
Quick set formula and bubble-free liquid is low in viscosity and self-levels for ease of installation - floor is ready to use in minutes
Dispenses with a regular caulk gun or the duo-pack cartridge system to provide maximum working time and precise application
Chemical reaction hardens to any depth without cracking or an increase in curing time
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
You'll be amazed at the versatility of our 3M™ Scotch-Weld™ Concrete Repair 600 repair system. It's 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 chemical 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.
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
Easy to use - Just clean damaged area and fill
Hardens to any depth without cracking or shrinking
Our 3M™ Scotch-Weld™ Concrete Repair 600 is a two -part component system. Our 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. Our fast curing adhesive formula provides a one minute work life.
What Are Urethane Adhesives?
Two part urethane adhesives cure chemically, 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 chemical exposure.
