How to Use Castin’ Craft Mold Builder

For three-dimensional artists such as sculptors, potters, and carvers, Castin’ Craft Mold Builder is a valuable tool to help create replicas of their creations for further production.

Castin’ Craft Mold Builder replicates the artist’s creation down to the last detail in a flexible mold to allow for castings or duplication processes to take place. 

How to Use Castin’ Craft Mold Builder

Castin’ Craft Mold Builder works very simply and is easy to use.  The artist simply takes the mold builder and carefully crafts a tight layer of mold builder around the three-dimensional sculpture to be cast.

The artist then waits until the mold is dry, and carefully removes the mold from the original object, taking care not to damage any protruding extensions on the original object.

The removed mold is then used to pour in plaster, molten metals like bronze (depending on the grade of the mold), or even ice if the artist is an ice sculptor.

The plaster, metal, or other medium should be given ample time to dry in the mold. Once the media dries in the mold, the latex mold can be carefully removed from the original art object by gently rolling it off the sides and then top of the object from the bottom up.

Cleaning the original art object and surface of the mold, countertop, or reproduction pieces may be accomplished with a simple solution of soap and water depending on the media being cleaned.

The media being molded should be the primary concern when selecting the best craft molder to create a duplication cast.

Artists seeking to cast molds of clay, ceramics, plaster, or wood should have no difficulty in removing a mold made with Castin’ Craft Molder. The mold is formulated not to stick to almost any surface.

Quick Drying Capability

A key concern for many artists is whether or not the mold product they are using will dry quickly once they have cast the mold.

Artists should strive to make sure that they are using a quick-dry product when it comes to ceramics, clay, and wood so as not to result in staining of the original piece.


Durability is a key concern of most artists when it comes to casting a mold of their artworks to facilitate duplication.

Artists do not want to have to recast molds over and over due to the mold not lasting, as continued casting from an original art object can reduce details in the original art.

A mold designed for durability such as Castin’ Craft Molder will facilitate many reproductions through its lifetime.

Works Well in Humid Conditions

Artists in humid climates like the southeastern United States and sub-tropics will need a mold that works well in humid conditions. Molds that do not work well in humid conditions will result in the mold failing to adhere to the object and thus reducing reproduction quality.

Castin’ Craft Molders will work well in humidity or any climate. Artists in humid condition will have no worries about drying or adhesion with Castin’ Craft Molders.

Artists should take care when it comes to selecting molding products that require chemicals to clean up. Molding products that require chemicals including acetone to remove them from objects can result in damaging the intricate details of the original piece of art being molded.

Castin’ Craft Molds clean with a simple solution of warm, soapy water, meaning an artist’s original work will not be damaged in the cleaning process.

Final Thoughts

Castin’ Craft Molds offer artists a uniquely efficient product to create molds of their original artworks for reproduction purposes.

Artists wishing to create molds of their three-dimensional art work for reproduction purposes should carefully consider all of the attributes of a molding product before determining whether it will work for their media and their climate.
