The Milliput Standard epoxy putty is at first soft and highly adhesive and then gradually hardens. The speed of hardening depends on temperature and at normal temperatures (20-25°C) Milliput becomes rock hard in three to four hours. With the application of heat the setting time can be reduced. After setting hard Milliput continues to cure and is fully cured after an elapse of time equal to the setting time at the same temperature. Once fully cured Milliput can be tapped, filed and painted. Milliput will set under water and is heat resistant up to 130°C.
Mix together equal parts of each stick from the pack. Knead and roll in the hands for at least 5 minutes until the colours merge and become uniform and no streaks can be seen, and then mix for another minute. The surfaces to which the putty is applied should be free from grease and dirt. Smooth surfaces should be cleaned with a suitable solvent or with soap and warm water to remove dirt and grease. Abrading the surface will improve adhesion. The putty may now be applied and will set hard in three to four hours without shrinking.
To truly smooth out your Milliput, apply Methylated Spirits with an old brush, the putty can also be thinned to a paint like consistency in this way for use filling or covering very light cracks.
