HydroSpan

A very unique product line allows you to expand or shrink your
three-dimensional molded product without losing details or quality. Hydrospan is water-activated; your molded product may be expanded to 161% or reduced 55 to 85% just by soaking in water. Both products are easy to work with and achieve uniform results when directions are followed. Almost any type of mold is compatible with Hydrospan when properly prepared. This line has been used by architects, artist, prototype makers, or anyone wanting to change the size of their original product, without losing dimensional integrity.
