A.	Verification of Conditions: Examine areas and conditions under which Work is to be performed and identify conditions that may be detrimental to proper or timely completion.
1.	Verify masonry joints found to be unsound, hollow, or otherwise defective, have been raked out to a depth of 1/2 inch (13 mm) and pointed with mortar.
2.	Verify cracks that exceed 1/64 inch (1.6 mm) wide have been filled with pointing mortar.
B.	Do not proceed until unsatisfactory conditions have been corrected.
3.2	PREPARATION
A.	Protection: Install coverings to protect adjacent surfaces. 
B.	Surface Preparation:

All other surfaces shall be cleaned by high pressure water; 3000 psi (20.7 MPa). High pressure water is the minimum cleaning that will be accepted, other methods, such as blast-tracking, mobile power scrubbing and sandblasting may be submitted for approval.
2.	Remove dirt, dust and materials that will interfere with the proper and effective application of the penetrating sealer. It is the responsibility of the Contractor to prepare the surfaces of the concrete to a condition acceptable to the Owner.
3.	Equipment during floor slab cleaning shall not exceed the height limitation of the facility and shall not exceed a 3,000 lbs (1360 kg) axle load or vehicle gross weight of 6,000 lbs (2721 kg).

2.	Brush apply water repellent only at locations where overspray would affect adjacent materials and where not practicable for spray application.
C.	Flood Application: Treat horizontal surfaces in a flooding application until the material ponds on the surface. After 10 or 15 minutes sweep, squeegee, or mop any remaining puddles to dry areas.
D.	Corrosion inhibitor shall be applied in accordance with the use of either spray, brush, or roller as per manufacturer's recommendations. Corrosion inhibitor shall be applied at a net coverage rate of 75 to 100 sq ft per gal (1.8 to 2.34 sq m per L) in two or three equal coats with a minimum one hr dry time between coats.
