A surface treatment for re-dressing worn, spalled, indoor or outdoor concrete surfaces to provide a “new concrete” finish. ARDEX CD is easy to apply, hardens quickly, is freeze-thaw resistant, and produces a surface finish which is suitable for foot and rubber tire traffic. ARDEX CD mixes with water to a creamy, smooth slurry consistency for application over existing concrete surfaces including sidewalks, patios, walkways, driveways, garage floors, pool decks and most vertical concrete surfaces. It readily bonds to concrete surfaces without priming, and can be applied by trowel, squeegee, or broom. Once applied, ARDEX CD can be broom textured before it sets for a reduced-slip surface. Dries fast, walk on in 2 hours, drive on in 6 hours. High strength - 4,000 psi. Coverage: (per 40 lb. bag) Approximately 120 sq.ft.
