Drill hole to the desired depth. For dowels and bolts one inch or less in diameter, hole should be drilled 1/8 inch oversized. For dowels and bolts greater than one inch in diameter, drill hole ¼ inch oversized.
Check bolt or bar for oil, grease, dirt or water that would inhibit good bonding. Clean if necessary
Blow dust from hole with oil-free compressed air. Use a compressed air wand with an extended tip that can be inserted to the bottom of the hole. When using compressed air, wear appropriate protective equipment to avoid ingestion of dust and damage to eyes. For best results, brush the hole and clean again with compressed air.
Insure that epoxy is being mixed at the proper ratio.
Inject epoxy, starting from the back of the hole. Pull out dispensing nozzle slowly while injecting. Try to avoid pulling nozzle out too fast and creating trapped air bubbles inside the hole. Stop injecting when hole is approximately ½ full.
Insert bar or bolt into hole, twisting slightly to insure even distribution of the epoxy. Push the bar or bolt completely to the bottom of the hole and check to see that epoxy has flowed to the top of the hole.
Allow the epoxy to cure before subjecting the bolt or bar to load.
