Surface Preparation
The substrate must be hard, sound, and free of dust and other materials that could hinder adhesion, such as paint, lime coatings, plaster, curing agents, laitance, and adhesive residues. Use a suitable degreaser to remove polish, wax, grease, oil, and similar contaminants before applying EP 310. Joints or cracks in the substrate where differential movement is anticipated, such as movement joints, should be brought through to the finished surface.
Features
Shrink-free Excellent strength Vibration resistance Resistance to heavy loads Corrosion resistance Easy to apply
Application
Pour the mixed material onto the prepared substrate without delay. Fix the bar into the hole immediately after pouring the grout, ensuring full contact of grout to the bar with a slight twisting action to maximize bonding. Avoid overworking the surface and do not mix more than can be used within the working time. Protect the work area during the installation process and initial curing time to prevent airborne debris from contaminating the surface of the wet resin. All movement joints in the substrate must be carried through the EP 310 and properly sealed.
Storage and Shelf Life
EP 310 has a shelf life of 6 months if stored in a dry place between 5°C and 30°C in the original unopened containers. The product should be protected from frost, direct sunlight, and sources of heat.
