Ion-Bond Armor is a subsurface elastomeric sealer for concrete, brick, and masonry. Penetrates up to 1.5 inches into concrete (3 times deeper than other siloxane sealers). Chemically reacts to form a hydrophobic barrier deep inside the substrate.
Use for waterproofing basements, foundation slabs, or retaining walls, outdoor concrete, bricks, and pavers. The only silane/siloxane sealer able to withstand negative-side hydrostatic pressure.
Use Ion-Bond Armor on concrete blocks and cinder blocks after sealing them first with RadonSeal Plus.
Before installing flooring on concrete slabs, use Ion-Bond Armor after sealing first with RadonSeal for the tightest possible seal against water vapor.
