The small-sized kit comes with all the components to complete the job, including our advanced Emecole Metro 555 Concrete Crack Repair Hybrid Polyurethane, Emecole 85-90 Concrete Crack Filler and Sealer, and the necessary dispensing accessories to repair up to approximately 20 feet based on a 1/4″ x 1/4″ chased crack.

Additional Components Required (Not Included)

  • Standard caulk gun (for dispensing of universal cartridge materials included with this kit)
  • Right angle grinder and Diamond tuck pointing/crack chasing blade *

* For hairline cracks that require chasing/opening, homeowners may use a right angle grinder along with a 4″ diameter, 1/4″ wide Diamond blade (otherwise known as tuck point or crack chasing blade). Right angle grinders and Diamond blades may be purchased at your local hardware store (some stores also rent out right angle grinders).

Repair & Strengthen Cracks in Concrete Slabs

As a very low viscosity water-like polyurethane material, Emecole Metro 555  has the capabilities of penetrating deep into cracks.  Emecole Metro 555 may also be used with Filler Sand (pure, wash and dried silica sand – available as optional add-on purchase with this kit), which allows for the application to use less material, while also strengthening the overall repair. The high bonding strength of Emecole Metro 555 fuses concrete back together, providing a strong crack repair that is completely filled from top to bottom with a cured tensile strength of 4000 PSI.

Protect Repaired Cracks from UV Exposure

The added component of Emecole Metro 85-90 provides UV protection to ensure that repaired cracks do not change color over time after being exposed to UV rays. Emecole 85-90 cures to a flexible, hard rubber like material. Its gray color matches most concrete surfaces, providing a clean finished look to the overall repair.

Protecting Repaired Slab Surfaces Against Excess Movement and Stress

When additional strength is needed to protect repaired cracks and the surrounding area of the slab from excess ground movement and freeze/thaw cycles, rely upon the Emecole Metro Carbon Fiber Stitching Dog Accessory Kit. Includes 18 single-tow Stitching Dogs, with installation accessories, which provides the reinforcement strength necessary to protect against the formation of new cracks or that previously repaired cracks do not re-open.
