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.
