PENETRATES Up To 2" Into Concrete, Brick, or Masonry (3 x deeper than a typical siloxane sealer) INDUSTRIAL GRADE - The Only Siloxane Able to Seal Against Negative Side Water Pressure. PERMANENT - No Re-Applications Needed. Virtually Indestructible. PAINTABLE - Leaves Surface Suitable for Paints, Adhesives, or Thinset PAINTED SURFACES - So Penetrating That It Even Waterproofs Through a Single Layer of Latex Paint Ion-Bond Armor penetrates deep into concrete (up to 2 inches) and forms a waterproof elastomeric barrier inside the concrete, leaving no film or color on the surface. Permanently waterproofs concrete against surface water and negative side water pressure. Greatly reduces infiltration of water, water vapor, moisture, and dampness. Use for waterproofing and damp-proofing basements, foundation slabs, retaining walls, and for sealing concrete slabs before installing flooring. Able to penetrate through one layer of latex paint to seal the concrete below (not guaranteed). Leaves the surface paintable. Easy and safe spray-on application. Coverage depends on surface porosity. Typical coverage: Poured concrete: 1000 sq. ft. / 5 gal. pail Concrete blocks: 700 sq. ft. / 5 gal. pail Cinder or split face blocks: 500-700 sq. ft. / 5 gal. pail.
