Once that solution dried, we applied a patented sealant called MAPS 2. This encapsulates mold, rendering it inert, harmless, and non-allergenic. MAPS 2 reactivates when it gets moist to prevent the growth of any future mold colonies. We also installed a SaniDry XP commercial dehumidifier to control the moisture levels in the basement. Once we were finished we recommended that the homeowner gets the foundation wall waterproofed to prevent moisture from seeping through the wall.
