Abstract
A gel material is expanded by first subjecting mixture of a gel precursor material and heat-expandable microspheres to a curing regimen which cures the precursor material into a gel material without expanding the microspheres and then heating to expand the gel material containing the microspheres. In this manner, an intermediate product in the form of a gel which is more handleable than the typically syrupy precursor material is produced. This intermediate product can be manipulated and placed at the intended application location and then expanded.
