the surface of the work pieces. Sand, dry ice and corncobs are just some of the different types of media used in blasting.  For the purposes of mold remediation, sodium bicarbonate (baking soda) and dry ice are the media commonly used.   Benefits of Abrasive Blasting Abrasive (or “media”) blasting provides

and structural damage to a variety of materials. Wind-driven rain is a common source of leaks. Solid:  As ice, moisture can form dams that cause melt-water to back up between shingles, creating leaks. Efforts to remove ice dams may damage shingles. Gas:  Moisture in its gaseous state is called moisture vapor

sheathing loses its ability to support roof loads and to hold fasteners. Moisture can also corrode structural metal components. Excessively high moisture levels in attics can cause both health and structural problems. Ice Dams Heat leaking into the attic can melt snow on the roof. Snow melt running down
