FIELD: foundry.
SUBSTANCE: invention relates to the field of foundry. Repair wax for correcting defects of models in investment casting contains 25-75% by weight of a recyclable wax paste and 25-75% by weight of a refreshing component. The re-use wax paste and the refreshing component are loaded into a metal container for 0.5-0.75 of the container volume, heated to a temperature of 80-120°C, stirred until uniform for 0.5-1.5 hours, then cooled to a temperature 68±2°C.
