1. Verify that surface is structurally sound, clean, free of dust,
dirt, paint products, previously applied water repellents, efflorescence
or other forms of contamination that could prevent proper penetration
2. Verify that surface cracks, holes and voids in excess of 1/16
inch (1.5 mm) have been repaired.
3. Verify that smooth formed concrete surfaces have been lightly
