APPLICATION

METAL ANCHORS IN PREFORMED HOLES IN CONCRETE: Preformed holes should be approximately ¼" (6.35mm) larger in diameter than the anchor bolt diameter. The depth of the hole should be 10-15 times the bolt diameter. Fill the hole from the bottom up, about half way with mixed epoxy and place the bolt, dowel or rebar. Top off with more epoxy and finish. All anchoring and doweling configurations must be approved or designed by an engineer.

CRACKS IN VERTICAL OR OVERHEAD STRUCTURES: For non-moving cracks and joints, use a trowel
to apply the paste full depth and strike off flush at the surface in a single pass. For structural crack injection repairs, use a dual-component gel pump.

PATCHES IN CONCRETE STRUCTURES: GEL PASTE makes a high-strength material for patching, topping, grouting and repairing spalls and other defects in concrete. Average thickness of the patch or topping should be no greater than ¼ to ½" (6.35 to 12.7mm) per lift.

SURFACE SEALING: Apply mixed epoxy over entire length of crack to be pressure injected. Ensure complete encapsulation to avoid leaking. Adjacent concrete surfaces must be mechanically abraded to ensure a proper bond. Allow for suitable cure time prior to injecting.

OTHER BONDING: To bond cured concrete or metal to concrete, apply a layer no less than a 1/64" (.40mm) to the prepared surface and join immediately. No firm clamping pressure is necessary beyond what will hold parts in place. When bonding fresh concrete to cured concrete, apply GEL PASTE at approximately
85-100 ft²/gal. (2.1-2.4 m²/L). NOTE: Cured concrete surfaces to be bonded should be at least 28 days old.

CLEANUP: Tools and equipment should be cleaned immediately with Toluene or Xylene. Clean equipment away from heat, sparks and open flame and avoid breathing vapors or allowing epoxy-containing solvent to contact skin. Should this material come in contact with the skin, wash thoroughly with soap and water; not solvent.

LIMITATIONS/PRECAUTIONS
Not recommended for use when the concrete temperature has been below 40ºF for the past 24 hours. Do not thin with solvents or use to seal cracks under hydrostatic pressure. Do not warm epoxy over direct heat . . . use the double-boiler method or store material in warm room for 24 hours prior to application. Unused epoxy will generate excessive heat, especially in large quantities. Unused epoxy should be mixed with dry sand in the container to help lower the heat.
