Epoxy.com Product #301 is a 100% solids low viscosity epoxy adhesive used to restore cracked structural concrete by the pressure injection method and to grout cracks in a horizontal plane by gravity.
Surface must be clean and sound. Interfaces of cracks must he free of dirt, laitance, grease, curing compounds and other foreign matter. Flushing with water through ports under pressure may he necessary prior to epoxy injection. Cracks may be damp or wet.
Temperature of Epoxy.com™ Product #301 must he 40°F. or above at time of mixing. Stir each component separately before blending. Best if used in an automatic binary mixing system. If mixed manually mix two parts by volume of Part A with one part by volume of B for three minutes with a low speed electric drill motor equipped with a mixing paddle.
For pressure injection set ports at intervals that approximately equal the thickness of the member to be injected in inches. Ports may need to place closer together for very fine cracks, or may be slightly further for wider cracks. Seal between and around each port with Epoxy.com Product #5, or #6. Inject Product #301 from an epoxy injection machine or binary hand or pneumatic injection gun. For more information consult Epoxy.com™ technical service department.
Minimum substrate temperature must be 40° F.
All tools and equipment should be cleaned before the system gels. Use methyl
ethyl ketone or any lacquer solvent.
