Mix-a-Mold Mixes

MIX NO. 1—Equal Parts of Cold Water and Mix-a-Mold

Intended Use—This mixture is intended for molding objects with undercuts.

Setting Time—Two to three minutes. Firmly push object, top side down, into the mix immediately.

Durability—The strength, flexibility and detail of the mold may be maintained for a short period of time if stored in an airtight container. Approximately 10% shrinkage will occur during that time, depending upon length of time mold is exposed to air while casting.

MIX NO. 2—Two Parts Cold Water to One Part Mix-a-Mold

Intended Use—This mixture is for general use for objects that do not have severe undercuts.

Setting Time—Five to ten minutes. Support the object in the mix, in position, for five minutes.

Durability—Flexibility, detail retention and strength are good. The mold may be used for repeated castings but shrinkage will be greater than Mix No 1.

MIX NO. 3—Three Parts Cold Water to One Part Mix-a-Mold

Intended Use—This mixture works extremely well to make molds of large thin models. Place model face up in bottom of shallow pan and pour Mix-a-Mold over model allowing 1 1/2" to 2” of mix completely over model. Let set, then invert pan releasing the model. Remove model and cast in the mold. Mix No. 3 is also recommended for the model with severe undercuts where you “peel away” the mold, sometimes destroying the mold in the process.

Setting Time—Ten to fifteen minutes for shallow molds. If you are placing the model into the mix, set three to five minutes after mixing before inserting objects so it will not “sink” too close to the bottom. Ten to twenty minutes for “peel away” molds. Hold or brace the object in a stationary position in the mix until it is firmly set.

Durability—The shallow mold may be used for as many castings as can be accomplished in a two to three hour time period before the mold shrinks. The “peel away” mold is very flexible, however, it has less strength and may possibly be used for one immediate casting only.
