Application
SURFACE PREPARATION
Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove surface contaminants, e.g. dust, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials.
Concrete: Abrasive blast or use other approved mechanical means.
Steel: Abrasive blast to white metal finish.
MIXING
Premeasure equal parts by volume of component A and component B in two separate containers. Use a third container to mix the two components together. (Do not use one tapered container such as a Dixie paper cup, filling it half full of A and half full of B; the correct ratio, 1:1, cannot be achieved due to tapered feature of container.) Thoroughly mix for 3 min. by hand or with low speed drill and Jiffy type mixer (400-600 rpm), scraping sides of container until uniform grey color is achieved. Mix only amount of epoxy that can be used within its gel time. Spread mixed epoxy thin on a hawk to extend gel time. If you pile it up, the gel time will be shortened, due to the greater mass and exotherm.
TO SET PORTS & CAP SEAL CRACKS
Dab a small amount of epoxy to the back of a port and carefully center port over the crack. A centering nail may be helpful. Do not apply so much epoxy to back of port that it could close off the hole. After setting port, carefully butter the shoulder of the port and extend epoxy to 1/2 in./1.28 cm on either side of the crack. Continue placement of epoxy by buttering crack between ports. To avoid leaks under pressure, the epoxy should be applied to approx. 1/4in/.64cm. thick. Do not place epoxy once it starts curing or getting hot or sticky, as this will compromise capseal and cause leaking. Once epoxy is placed, it should not be disturbed during the curing process. Cure time depends on air temperature and mass of epoxy. Capseal must be fully cured prior to injection.
TO BOND IRREGULAR SURFACES
Apply the mixed Pro-Poxy(TM) 300 PASTE to the prepared substrates. Work into the substrate for positive adhesion. Secure or clamp the bonded surfaces firmly into place until the epoxy has cured. Glue line should not exceed 1/8 in./0.32 cm.

First Aid
EYE CONTACT: Flush immediately with water for at least 15 minutes. Contact physician immediately.
RESPIRATORY CONTACT: Remove person to fresh air.
SKIN CONTACT: Remove any contaminated clothing. Remove epoxy immediately with a dry cloth or paper towel. Solvents should not be used as they carry the irritant into the skin. Wash skin thoroughly with soap and water.
CURED EPOXY RESINS ARE INNOCUOUS.
