16lbs of Exhibit Mold equaling roughly 2 gallons of material. Enough material to make multiple large rock molds, multiple small/medium backgrounds or a single large background up to about 48x21, and very large waterfalls/stream designs. Best value per pound and great for large projects!

Exhibit Mold was designed to be used in conjunction with Exhibit Cast, but other casting agents can be used.

One of the many features unique to this material is it can be mixed quickly in large volumes. Other silicone molding putties are too thick to be easily mixed by hand in large batches which makes taking background sized molds challenging. Exhibit Mold allows you to quickly and easily hand mix large volumes with ease allowing you greater size flexibility on how big a mold you can make. It also means you don't have use as much force to capture the surface detail and is overall less taxing on the hands.

Another unique feature of Exhibit Mold is its cure time and "pot life". With a final cure time at only an hour at 80°F, its ideal for use in the field. The extended 'pot life' (the time until each hand mixed batch is too firm to press onto the model's surface) was designed to allow for large molds to be made. No other molding putty has Exhibit Mold's extended pot life, with a final cure time of only an hour, and smooth dough-like viscosity for ease of mixing.  Ideal properties for molding while in the field!
