  1. Remove the cap from the 633 Epoxy Adhesive. Dispense a small amount of adhesive until adhesive is flowing from both sides of the syringe.
    • 25ml Hand Syringe: Push adhesive out in equal amounts in provided mixing cup and mix thoroughly with mixing stick until the color is completely uniform.
  2. Clean the area to be bonded and the glue-on fastener with alcohol. Surface must be clean and dry for good adhesion.
  3. Carefully apply 633 Epoxy to the base of the glue-on fastener and set in the desired position on the underside of the countertop around the sink cut-out.
  4. Allow 45-60 minutes for adhesive to reach the proper handling strength.
    • Note: Adhesive will continue to cure for up to 24 hours.
  5. Once the adhesive has reached handling strength, place the sink into position, mount the ‘Z’-shaped sink bracket onto the glue-on fastener, add washer, then tighten with the wingnut.
