A + B Epoxy Paste is a two part epoxy that mixes to a smooth paste like consistency that holds to vertical surfaces without dripping or running. It can fill holes, be used for thin surface fills and can be feathered to a fine edge. It cures in about 5 to 10 minutes to a finished color of bright white. It is packaged in two 5 oz. tubes (1 tube each of resin and hardener).
