Rapid Surface Repair

Product Description

nanoGARD™ AR is a unique, low viscosity, two-part liquid, polyurethane-hybrid polymer. When supplemented with aggregates, this product is used to repair and rehabilitate concrete and asphaltic concrete pavements. The enhanced polymer is high performance, rapid setting, and can be used to make a resilient polymer concrete. Within minutes of placement, durable, long-lasting repairs are able to handle vibration, heavy traffic, and thermal movement.

This product is also available in a Moisture Scavenging version (
nanoGARD™ AR-M) to improve set in high moisture cure environments.

Advantages

  • Waterproof, chemically resistant membrane protects substrates from freeze-thaw spalling. Stops further corrosion of reinforcing steel
  • No priming required to bond to concrete, asphalt, steel or wood
  • Liquid becomes solid (cures) in as little as 60 seconds. Traffic Ready in as little as 10 minutes
  • No toxic fumes during application. Low odor
  • Make repairs, resurface pavements, and apply protective coating year round – hot or cold.

USES

  • Resurface walkways, floors & bridge deck overlays
  • Resurface walkways, floors & bridge deck overlays

PLacement Guidelines

Surface Preparation
  1. Prepare surface to a minimum CSP-4 (Concrete Surface Profile per ICRI Technical Standard 03732) profile by removing all surface contaminants, including sealers, oils, or other bond inhibiting substances via chipping or similar mechanical method.
  2. For overlays, cut keyway channel (groove) using concrete saw equipped with dry cut diamond blade around perimeter of area to be resurfaced. Keyway channel (groove) depth shall be a minimum of ½ inch (12.7 mm). Surfaces adjacent to a vertical plane (such as curbs, walls, tanks, etc.) shall have keyway channels cut approximately 4 – 6 inches (101.6 – 152.3 mm) back from vertical plane towards the interior of area to be resurfaced. Keyway channel shall be ½ inch (12.7 mm) deep by ½ inch (12.7 mm) wide.
  3. For overlays, chip 2 inch (50.8 mm) wide taper back from interior edge of keyway channel at all termination edges (ie: drains, doors etc.). Using bush hammer or chipping gun equipped with a 1 – 2 inch (24.4 – 50.8 mm) wide spade blade, chip a 2 inch (50.8 mm) wide taper back from edge of interior keyway channel (groove) inward towards the area being resurfaced. Taper shall match depth of keyway channel at its deepest point, which is the edge of the keyway, and taper out to 0 inches at its most shallow point, 2 inches (50.8 mm) towards the interior of the area to be resurfaced
  4. Route out all cracks to a minimum of ½ inch (12.7 mm) wide by ½ inch (12.7 mm) deep, using concrete saw equipped with dry cut crack chasing blade. Scarify vertical saw cut surfaces.

  5. Vacuum surface free of all dust and dirt.

  6. Surfaces must be completely dry and free of moisture prior to installation.
Installation
  1. All application equipment shall be in good operating condition.
  2. Materials shall not be applied when the ambient air temperature or the surface temperature is outside the boundaries as stated on the product data sheets and application guidelines.
  3. Keep material out of sun or hot areas prior to applying, as this may cause working time to be diminished and could cause poor appearance and/or adhesion. If room and or concrete surface is hot (85ºF or more) you can spray with cool water and soak for a period to cool surface. Vacuum the surface free of water, and torch dry if necessary, prior to applying product.
  4. Damp surfaces must be thoroughly dry prior to the application of product. This step is essential for proper cure, adhesion, and post cure performance.
  5. Product shall be maintained at 50ºF – 80ºF.
  6. Product may be installed between 20ºF – 100ºF.
  7. For temperatures above or below these limits please consult of ICP technical departmen
Mixing and Installation Instructions

NOTE: Mix ratio is 1:1 by volume. Auto mixes in plural component self-cleaning pump system.

Hand Mix Instructions:

Mix a small sample before working on your specific project so you will know what to expect as to what product looks like while setting and curing. Mix a small amount of material for a test. Remember, as material quantities increase, heat generated by the product increases and the potlife of mixed product will decrease respectively.

Clean-Up:

Clean tools immediately after use with xylene or MEK.

Considerations
  • Product should be stored at 50–80°F (10–27°C).
  • Product may be installed between 20–100°F (-6–37°C).
  • Keep material out of sun or hot areas prior to applying, as this may cause working time to be diminished and could cause poor appearance and/or adhesion.
Caution

This product may cause skin and eye irritation. Do not inhale vapors. Provide adequate ventilation. Protect against contact with skin and eyes. Wear rubber gloves, long sleeve shirt, goggles with side shields. In case of contact with eyes, flush repeatedly with water and contact a physician. Areas of skin contact should be promptly washed with soap and water. Do not take internally. Keep product out of reach of children. PRIOR TO USE, REFER TO SAFETY DATA SHEET.
