Introducing Roadware MatchCrete™ Clear

 

Roadware MatchCrete™ Clear (MCC) is a two component aliphatic polyurethane for repairing cracks, spalls, and joints in concrete subject to UV exposure from sunlight. This material is clear in appearance when applied and cured. Colored sand and pigments may be added to create color stable repairs that match most any decorative or shade of concrete surface. MCC will not significantly change color with exposure to sunlight over time.

Use Roadware MatchCrete™ Clear (MCC)  to quickly repair cracks and spalls in concrete that is exposed to sunlight and where a color compatible appearance is desired.

Who would want a “clear” concrete repair product? What could you use it for?

For over 15 years, Roadware manufactured 10  Minute Concrete Mender™ in one standard concrete grey color. It was simple and straight forward. Concrete is grey! The repairs should be grey.  Then everything changed. In the past five years, decorative concrete has exploded into the marketplace.  Now you can have your concrete in nearly limitless color choices and textures. We developed MatchCrete™ Clear to give you endless color possibilities as well. So, what can you do with MatchCrete™ Clear?

Cracks and Saw-cut Control Joints:

  • Clear- Use MCC without sand to create an eye pleasing joint that will not distract from the overall look.
  • Colored and Clear – Stain the sidewalls of a crack or joint  and fill with MCC to create a colored joint effect.
  • Colored Sand- Use MCC with colored sand or colored quartz to make nearly any color repair.
  • Colored Aggregate- Use MCC and colored aggregate to make a granite or stone effect.
  • Concrete Dust- Use MCC and concrete dust to make a portland concrete look.
  • Dry Pigment- Use MCC, sand, and some dry concrete pigment to create most any matching color.
  • Dry Shake- Add a bit of dry shake color to your MCC repair for matching color effects.

Decorative Use:

  • Joints and Cracks- Fill joints and cracks around concrete, stone, tile, or terrazzo without becoming an eyesore.
  • Exposed Aggregate- Repair cracks, spalls, and knock-outs.
  • Pool Decks- Repair coatings and de-laminations.

Polishing:

  • Joints- Use MCC for polished joints that match the concrete and look good.
  • Design- Use MCC to embed items into the concrete and polish the surface flush.
  • Lighting- Use MCC to embed LED lighting into concrete walkways and decks for dramatic effects.

Exterior Use:

  • Use MCC in areas exposed to sunlight where color stable repairs are necessary such as driveways, sidewalks and entryways.

Architectural  Use:

  • Use MCC to repair cracks, joints and spalls in high profile building entrances, courtyards, and common areas. Repairs with MCC will not distract from the overall appearance and design.

Concrete repair for freezer and cold storage warehouse floors


If your business is refrigerated warehousing or grocery distribution, Roadware 10 Minute Concrete Mender™ is the premier concrete repair product for keeping your floors in top condition. The unique Microdoweling™ polyurethanes in Concrete Mender™ will cure at temperatures well below -20 degrees F. ( -28 C) in just a few hours. You can repair cracks, spalls, slabs, joints, and surfaces while the warehouse is in service.
Features:
  • Easy to mix one-to-one ratio polyurethane.
  • Add manufactured sand to extend the material over to two times. Two gallons of Concrete Mender™ will make 4.4 gallons of repair material.
  • Ultra low viscosity for easy application and workability.
  • Microdoweling™ penetration into the concrete for load transfer bonding.
  • Cures only has hard as the concrete. Will not become brittle like epoxy.
  • Tough repairs that can take industrial levels of punishment.
Benefits:
  • Smooth and safe floors.
  • Less damage to forklifts and equipment.
  • Clean floors. Meets FSIS and USDA guidelines.
  • Less tipped loads and damaged product.
  • Reduced cleaning and floor maintenance costs.
  • Reduced workers comp claims attributed to accidents.
Cold environments such as walk-in freezers and refrigerated warehousing pose difficult challenges for repairing concrete. In temperatures less than 0° F, most repair materials become unworkable and may take many hours to set and cure. Most epoxies are not usable below 32° F. Roadware Polyurethanes have been used in temperatures as low as -20°F below freezing. Listed below are some problems and solutions for working in cold environments.
Cold Environment Challenges
Frost: Frozen moisture in the concrete will act as a barrier between the repair material and the pours of the concrete. Most repair materials will try to bond to the frost coated concrete. When the temperature increases, the frost melts and so does the bond.
Working Conditions: Working with materials in the cold is challenging to both man and materials. Mixing epoxies or mortars in the cold is especially challenging. As the temperature decreases, the viscosity and flow rate of these materials increase making them harder to mix and much more difficult to work with.
Curing: With most materials, cure times in cold environments are extended significantly. A product that normally cures in an hour at room temperature may take as much as 12 hours in a cold environment. Some materials may not cure at all before actually freezing solid.
ROADWARE Solutions
The extremely low viscosity and rapid cure times of Roadware 10 Minute Concrete Repair products make them excellent for cold environment application. Successful repairs are routinely made at temperatures below -20°F in freezer floors.
Preparation: Prepare cracks, joints, and spalls according to standard recommended methods. Make every effort to remove any moisture from the repair area. A propane torch or heat gun is very helpful in removing frost and moisture. In extreme cold, it is necessary to heat up the concrete prior to application.
Application: Keep material and sand or aggregate warm. Place materials in a warm area (between 70°F and 90°F) prior to application. Warm cartridges mix better, flow easier, and cure faster. Apply material as directed. It is a good practice to pre-wet all concrete surfaces with material before the introduction of sand. This insures full penetration and a strong bond.
Curing: Roadware materials are designed to cure in approximately 10 minutes when all components involved are at 70° F. In cold environment, the cure time depends on the temperature of the material, the temperature of the sand or aggregate if used, the volume of the repair, and the temperature of the concrete. Below is a chart of approximate cure times at various temperatures and conditions.
Storage: Roadware material should be stored between 60°F and 80°F. Material stored in extremely cold environments should be slowly brought up to room temperature before use. It may be necessary to agitate material subject to extreme cold prior to mixing. Call Roadware Technical Services for further instructions (800-522-7623).
