Abstract
Abstract A kit containing the components essential for repairing, in situ, damaged or fractured porcelain plumbing fixtures and the like. A method for carrying out such repair includes cleaning, shaping, and priming the damaged area, applying a bonding agent preferably containing two silanes and a water-displacing solvent, then applying a filling agent comprising a blend of vitreous powder, a powdered polymer, and a resin binder, allowing the agent to set and harden, and finishing. A filler composition or agent and an advantageous bonding composition are also provided.
