Milliput is an epoxy putty. Milliput produce five grades: Standard Yellow/Grey, Silver Grey, Superfine White, Terracotta, and the latest addition - Milliput Black. Each grade is presented in similar packs containing 2 x 56·7gm. sticks and the general instructions for preparation and usage are the same. The two sticks have a long shelf life but once mixed the resultant putty is at first soft and highly adhesive and then gradually hardens. Speed of hardening is dependant on temperature and at normal temperatures (20-25ºC) Milliput becomes rock hard in three to four hours. By the application of heat the setting time can be reduced to a few minutes.
Superfine White Milliput is specially formulated for the restoration of porcelain and ceramics where a fine finish is desired. Milliput also allows for missing parts to be reconstituted. Superfine White Milliput is recognised as one of the finest materials available for ceramic restoration
