● Drill the hole to proper depth and diameter per specifications using drill systems.
● Clean the hole using brush and compressed air.
● Use specialized cartridge, place the cartridge into the dispensing tool, discard the first several times of injection until an even-colored mixture is extruded.
● Insert the mixing nozzle to the bottom of the hole, and inject adhesive until the hole is about 2/3 full.
● Embed the steel anchor element to the bottom of drilled hole clockwise slowly.
● Check the surface of the hole if there is any overflow to ensure the hole is full. There shall be no gaps between the anchor and the wall of the drilled hole. Clean any excess resin from around the mouth of the hole.
● Do not knock or strike the steel during cure time.
● Finish installation and continue the follow-up construction.
