This ceramic cement is used to attach or repair greenware or bisque. Gently scratch crisscross lines on areas to be joined and, using a soft brush, moisten scored areas or broken edges with water. Use the same brush to apply a coat of Patch-A-Tatch to these areas. Quickly attach or fit the pieces together and hold securely for a few seconds. Brush a small of Patch-A-Tatch over the joint and, when set and thoroughly dry, scrape, sand, sponge or otherwise finish. Clean up with water. For use with cone 04 ceramics only.
