Will epoxy stick to dried epoxy?
Epoxy applied over partially cured epoxy will chemically link with it and is a primary bond. The ability to chemically link diminishes as the epoxy cures and it becomes a secondary bond. Secondary bonding relies on the mechanical linking of an adhesive to a material or cured epoxy surface.
How do you recoat epoxy resin?
All you need to do is wash the surface thoroughly with clean water and an abrasive pad and then dry it with fresh paper towels to rub off the amine blush before it dries on the surface again.

How do you fix epoxy craters?
Lightly sand the existing epoxy with 120-150 grit. Care should be taken not to cut through the stain. Apply another seal coat of epoxy using an 1/8″ nap foam roller, working to fill in the craters. Allow the epoxy to cure hard, sand entire application flat, and re-coat to finish.
Why does my resin have so many bubbles?
Porous, organic materials like wood, leaves, fabric and even paper can “breathe” air. When you cover these materials with resin, the air bubbles release into the resin in the form of bubbles, sometimes hours after you have poured and torched.
