Clean the edges of the Corian countertop with denatured alcohol to remove wax, grease, dirt and dust.
Load a caulking gun with tinted epoxy and squeeze out a thick long bead along the entire edge.
Push the two ends tightly up against each other.
Clamp the two pieces together or wedge pieces of lumber along the exposed countertop edge and a nearby wall to hold the joining edges together tightly.
Allow the epoxy to dry completely, usually 4 to 6-hours.
Sand the seam with a fine-grit sandpaper loaded into a belt sander or orbital sander. Do not apply pressure, allow the sander to do the work or you will cause depressions in the countertop.
Sand the entire countertop with an extra-fine 220-grit sandpaper loaded into an orbital sander.
Buff the countertop with an orbital sander equipped with a polishing bonnet to achieve a glossy surface.
