, and Molybdenum. DeconGel has special properties that “wet out” a surface allowing the gel to penetrate into contiguous pores. Often contamination is considered “fixed” when in fact the contaminants are actually “loose” but trapped within pores, unable to be removed via common decontamination techniques. DeconGel can get within these pores and remove these contaminants making it appear that DeconGel has actually penetrated the substrate. DeconGel can be applied by brush, trowel (small hand-held or large stand-up trowel) or sprayer (sprayer and/or product may need to be modified to work). For small surface areas a paint brush, a small trowel or a hand-held sprayer can be used. For large complex surfaces, an industrial type sprayer may be more practical. For large horizontal surfaces, either a sprayer or a stand-up trowel may be used. When spraying DeconGel, multiple coats may be needed before peeling the gel from the surface. The thicker the dried gel is, the easier it is to remove from the surface.
