Getting Started With Milliput

Getting Started With Milliput

Milliput is a trade name for epoxy putty. There are 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 (20-25ÂșC) Milliput becomes rock hard in three to four hours. By the application of heat the setting time can be reduced to a few minutes.

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 machined, drilled, tapped, turned, filed, sawn, sandpapered and painted. Milliput can be sandpapered and painted immediately it has set. (it is advisable to wear eye protection during this process).
Milliput is an excellent adhesive and will bond any of the following to itself or to any of the others - wood, brick, cement, metals, concrete, plastics, glass etc, but note that Milliput is not intended as a thin layer adhesive and should not be used where a paste, mucilage or thin glue is indicated. Milliput will set under water and is heat resistant up to 130°C.
Shelf Life:
We recommend Milliput is stored in cool, dry conditions. Please reseal bags after use. Stored correctly this product should remain workable for about 2 years.

Black Milliput was introduced in response to user demand and can be used for Repairs to antique clocks, Guttering, Ebonised wood, Marble, Slate, Cast iron, Basalt ceramics and black plastic parts in cars (such as bumpers, small handles, buttons and knobs).

Yellow-Gray Milliput The epoxy putty with a thousand uses in modeling D.I.Y and industry. (Car repairs, military models, Marine craft repairs, household repairs like gutters)
Silver Grey Milliput was introduced as slightly  finer filler and is widely used for modelmaking, sculpting, taxidermy and for the repair of garden ornaments. (porcelin restoration- dolls & plates, Military Modeling, Domestic Repairs, ).
Superfine White Milliput For the restoration of porcelain and other ceramics for the repair of antiques, objects d'art, Victorian dolls, picture mouldings, etc. For sculpting and modeling. For the repair of white domestic chinaware and for filling scores and dents in white domestic equipment e.g. washing machines, refrigerators, etc. (porcelain restoration- dolls & plates, Military Modeling, Domestic Repairs, ).
**It is very important when using this grade of Milliput, because the sticks are virtually the same colour, that you mix the two parts for at least five minutes.**

Terracotta Milliput used for the restoration of terracotta and other ceramics. Also for the repair of garden urns, pots, Statuettes and damaged brickwork, etc. Also for sculpting and modeling. (Earthen wear pots, Quarry Tiles, Statuettes, damaged brickwork)

Use Milliput to add features for realism to models and figures or to customize.

A "Cool" Tip!
If you are interrupted while you are mixing Milliput, you can put the Milliput into a deep freezer until you can get back to work. This will keep the product at approximately the same state of setting at which it was frozen for up to 36 hours. Simply remove the now frozen product from the freezer and warm in the hand and it is ready to use. If stored immediately on mixing it retains its sticky nature.
Milliput crusting cure
Tom Sime - Epoxy 101
There are differences between brands of epoxy putties but they all have very similar properties.

I have used Milliput, AB as well as Magic Sculpt and if Milliput is used, as a “base line” AB is a little firmer in texture and Magic Sculpt is a little softer as well as having a surface “sheen” that (I find) makes judging depth a little more difficult than with Milliput.

One of the big problems when you purchase Milliput is that you don’t know how old it is. The darker stick has a tendency to “crusting” on its outside surface if its kept in storage for to long. If this is not dealt with then when you mix the two components you will have small pieces of the crust in the mix that will not cure properly as the Milliput hardens.

The cure for crusting is as follows-
1) Warm an oven to 200 Centigrade/Celsius.
2) Place the encrusted stick on a piece of foil and put into warm oven.
3) Make a cup of coffee/tea and drink it. This should take you 20 minutes.
4) After 20 Minutes carefully remove HOT Milliput from oven remembering that its HOT and STICKIE and if you touch it will STICK to YOU and BURN.
5) Allow the Milliput to cool till it is warm to the touch (don’t let it go cold) and you can handle it without burning yourself.
6) Now simply mix it well with itself thoroughly, this will take at least 3-5 minutes.
When the mix cools completely you will find that the lumps have been reconstituted and are no longer a problem.

All epoxy putties change in consistency between mixing and curing. At the time of mixing epoxies are soft and pliable, as time passes they tend to firm up and are less easy to work with sculpting tools. This knowledge can be used to your advantage.

Putty that is freshly mixed is soft and therefore ideal for sculpting and shaping with dental tools, toothpicks and homemade tools designed to meet your personal needs. I use Milliput for figure sculpting and use a selection of various sized needles that have been epoxy glued into the handles of old paintbrushes. A paintbrush moistened with a little water can be used as an aid to sculpting, blending and smoothing out the surface of whatever you creating. 

Putty that is no longer soft and malleable need not be discarded. If it has started to firm up it is perfect for rolling out and being cut and shaped for clothing, tarps, blankets, bedrolls etc. To roll out the putty simply dust it with a little talc place it on a flat surface and use piece of dowel/plastic rod to roll it out. Use a moist paintbrush to remove the talc before “fastening” into its final place.

There are few things more satisfying than creating your own sculpture/conversion. I hope the forgone helps you to do just this.

Another customer adds - A quicker method that I use is to place the "crusty" one on a glass dish and microwave on full power for approximately 10 seconds (depends on m/w output), then mix with itself.  just remember it is HOT when it comes out of the micro.
