Perdüre CR | polymer modified concrete repair compound

Perdüre CR is a single component, polymer modified concrete repair compound designed for filling and repairing concrete and masonry surfaces above, on or below grade. It is suited for patching and/or resurfacing distressed horizontal surfaces. It is intended for fast turnaround repairs and contains a special migratory corrosion inhibitor. When mixed with water, it results in a consistent mix that can be troweled, shaped and shaved after the initial set.

Perdüre CR is a general purpose concrete repair material used to fill spalls, gouges, dormant cracks and other low areas in existing concrete surfaces, including sidewalks, patios, plazas, courtyards, walkways, driveways, parking garages and pool decks. It can also be used to re-form concrete steps, pre-cast products, concrete pipe, curbs, sidewalks, bridges, panels and walls. It also can be used to fill honeycombs, form tie rise holes, spalls or irregularities due to misaligned forms or unconsolidated concrete. Once applied and allowed to dry properly, Päram, Sgraffino or Überdek can be installed over the entire area to create a desired appearance.
