Emecole 302 1:1 is a high-modulus epoxy gel designed to seal cracks and surface ports onto concrete prior to injection. It can also be used for bonding miscellaneous materials to concrete where a fast cure is required. 302 1: 1 is moisture insensitive and will cure in damp environments.

C) Surface sealing, one cartridge will cover approximately 10ft of crack and ports


As with any epoxy adhesive, surface preparation is critical. Concrete surfaces should be cleaned by sandblasting, wire brushing, or other mechanical means. All loose or unsound material must be removed. Surfaces should be dry and dust-free to ensure a superior bond. Emecole 302 1:1 will cure in the presence of moisture although application onto wet surfaces is not recommended.

Use M.E.K. or Xylene. Clean equipment immediately after use.

This product can cause skin irritation. Always wear protective clothing. Wash contaminated areas with soap and water, never solvent. In case of eye contact, flush with water for 15 minutes; immediately see a physician.

The fast setting port sealing paste Epoxy is used primarily for setting injection ports in place and general sealing over cracks before injection and sets in less than an hour.
