Surface Preparation


All surfaces must be clean and structurally sound; free of dust, grease, oil, sealers, paints and other contaminates. New concrete to be repaired must be cured 28 days. Pores of the concrete surface must open to allow proper bonding. This type of surface can be achieved by mechanically abrading the surface of the area to be repaired. Remove dust by vacuum or compressed air. Substrate to which repair mortar is to be bonded should be in a saturated surface dry (SSD) condition. For proper methods to abrade, clean and prepare concrete, refer to ASTM Standards D4259-88 (Standard Practices for Abrading Concrete); D4261-83 (Standard Practices for Surface Cleaning Concrete Unit Masonry for Coating), D4258-83 (Standard Practices for Surface Cleaning Concrete for Coating).

Specific surface preparation requirements for each product are included in the Product Literature Sheets.
