WHERE TO USE

Use neat for grouting damp and dry cracks or as a penetrating sealer on concrete.
Epoxy Injection of hairline and small cracks
Mix with 3 parts Epoxy.com Product #76 Epoxy Extender to grout base plates, set anchor bolts
Mix with 4 parts Epoxy.com Product #76 Epoxy Extender for a self-leveling grout.
Mix with up to 5 parts of Epoxy.com Product #76 Epoxy Extender for a patching mortar.

SURFACE PREPARATION

Remove dust, laitance, grease and curing compounds from concrete surface by sandblasting, grinding or wire brushing as required - see Epoxy.com Surface Preparation Guidelines for more details. Cracks may be dry, damp, or wet.

MIXING

Material should range between 65°F (18°C) and 75°F (24°C) to facilitate ease of mixing. Stir each component lightly prior to proportioning. Mix 2 parts Component A with 1 part Component B. Mix thoroughly for 2-3 minutes with Epoxy.com -Mixing Paddle and low speed drill 3 minutes and until color is uniform. When mixed with Epoxy.com Product #76, color of mixed material is gray in color. For Epoxy Injection of Concrete and Wood

APPLICATION:

AUTOMATIC PRESSURE INJECTION

Epoxy.com AUTOMATIC PRESSURE INJECTION MACHINE - Contact Epoxy.com Technical Support Department for more details

MANUAL PRESSURE INJECTION -

Place injection ports every 6" to 10" along length of crack. Seal surface of crack to be grouted with Epoxy.com Product #6 Epoxy Gel Adhesive. Pump Epoxy.com Product #307 into lowest port. When epoxy reaches next highest valve, move up and repeat procedure. Remove port after cure if desired. See Epoxy Injection for more details.

PENETRATING SEALER:

Apply mixed material with rubber squeegee or roller. Allow time to penetrate. Squeegee off excess while still liquid.

PATCHING

Apply neat Epoxy.com Product #307 to prime the clean sound substrate. Mix blended epoxy with Epoxy.com Product #76 epoxy filler or Epoxy.com Product #75 epoxy filler and trowel in place.

ANCHOR BOLT GROUTING

Diameter of hole should be minimum of 1/2" larger than that of bolt.

YIELD

One gallon of mixed Epoxy.com Product #307 will yield approximately:

750 cu. in. when mixed with 3 gallons of Epoxy.com Product #76 - very pourable

925 cu. in. when mixed with 4 gal Epoxy.com Product #76 - self-leveling

1100 cu. in. when mixed with 5 gal Epoxy.com Product #76 - masonry mortar

LIMITATIONS

Do not thin Epoxy.com Product #307 solvents will prevent proper cure.
Do not use for bonding new to plastic concrete, use Epoxy.com Product #7 for that.
Substrate temperature and ambient temperature must not be below 40°F(4°C).
Exposure to elevated temperatures for prolonged periods is not recommended.
Epoxy resin (A Component) may crystallize. Heating material to 120°F and stirring will reconstitute material to original condition. Allow to cool before using.
May be too low a viscosity for larger cracks.

CAUTION

WARNING! “A” Component contains epoxy resin May cause skin sensitization or other allergic responses. Use with good ventilation, particularly if material is heated or sprayed. Wear protective clothing, goggles, gloves and/or barrier creams. Keep container closed when not in use. Wash thoroughly after handling.

DANGER! “B” Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. Use with good ventilation, particularly if material is heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves and/or barrier creams. Keep container closed when not in use. Wash thoroughly after handling.

FIRST AID

In case of skin contact, immediately wash with soap and water. In case of eye contact, flush eyes with copious amounts of water for at least fifteen (15) minutes. Remove contaminated clothing shoes. If irritation persists, seek medical attention. Wash clothing before reuse.
