Description
MC-Epo Inject is a two-component solvent-free epoxy material designed for injection and sealing needs. The approved source references ASTM C881 Type 1, Grade 1, Classes B and C.
Where to use
Injection of vertical and horizontal cracks in concrete.
Advantages
Excellent adhesive for pressure injection of fine cracks. Moisture-insensitive bonding to dry or damp surfaces. Tough, weather-resistant seal for porous concrete. Penetrates deeply into concrete cracks.

Crack preparation
Remove deteriorated parts from the crack to a maximum depth of 5 mm. Minimum age of new concrete: 28 days.
Mixing
Thoroughly mix component A with component B according to the stated mixing ratio.
Application
Horizontal cracks may be gravity-fed or pressure-injected. Vertical and overhead cracks must be pressure-injected. Seal areas around entry ports and the crack between ports. Inject neat material using an epoxy injection machine or other mechanical means. Continue until the crack is full.
Safety
Prevent material from entering the eyes, avoid skin contact, provide adequate ventilation, and keep away from sparks and flames where solvent-containing materials are involved.
Cleaning
Clean tools and equipment with a suitable epoxy thinner.
