Disaster Recovery Support – Proper Mold Clean-Up


When restoring water-damaged structures caused by flooding, hurricanes, storms and other catastrophes, taking measures to not just eliminate mold, but to prevent its recurrence is vital. Cleaning and sanitizing alone does not prevent mold from recurring. To ensure mold does not return, many industrial hygienists and contractors employ a Clean, Kill and Coat™ remediation process:

  • Clean: Sets the stage for remediation. Unsalvageable materials, such as carpet, furniture and wallboard are removed. Building materials are exposed to circulated dry air, followed with a thorough cleaning and the
    removal of all contaminants.
  • Kill: Disinfects and deodorizes to prepare the surface prior to sealing or coating. Foster® 40-80 Disinfectant disinfects hard non-porous surfaces and cleans and deodorizes areas of mold, mildew and bacterial growth resulting from flood and water damage. It should be used as the final step in the cleaning process on hard non-porous, semi-porous and porous surfaces. This full-strength disinfectant is EPA registered and comes in a ready-to-use dilution, eliminating the need to handle corrosive or dangerous concentrates.
  • Coat: Prevents mold re-growth long term. Surfaces are coated with a Foster® EPA registered, antimicrobial coating or a Foster® mold resistant coating. Foster coatings contain a high percentage of active ingredients, so they inhibit the re-growth of odor-causing bacteria, mold and mildew – long term – on their surfaces.

Foster® fungicidal protective coatings are specified by industrial hygienists and preferred by contractors because of their long term, proven performance and reliability. Foster coatings are used in mold remediation projects and in HVAC duct systems, for wherever indoor air quality is of utmost importance – school buildings, hospitals, restaurants, homes, and work places. Foster coatings (listed below) are also LEED compliant and contribute to LEED EQ Credit 4.2.
