Handle material with lead paint contamination according to Section 1.1D.

Raze and remove obstructions interfering with the work and not designated to remain.

Concrete removal in repair areas. Saw cut ¾ inch (19 millimeters) deep along boundaries of repair areas. Use power-driven hand tools to remove existing concrete. Do not damage concrete designated to remain in place.

Where the bond between existing concrete and reinforcing steel is destroyed, remove concrete adjacent to the steel to provide at least ¾-inch (19-millimeter) clearance for the new concrete to bond to the reinforcing steel. Use care to prevent damage to remaining concrete when achieving the final surface.

Clean exposed concrete surfaces that will be in contact with repair material. Provide a residue free surface.

B. Concrete Repair. For concrete repairs, remove existing or new defective concrete according to Subsection 3.1 (A) above. After removal of deteriorated or unsound concrete, shotblast exposed structural steel, reinforcing steel, and concrete surfaces which will be in contact with repair material until free of rust and foreign material. Clean the sound concrete surface by flushing with clean water from a high pressure water jet or compressed air. Remove and replace deteriorated reinforcing steel. Before placing repair concrete, thoroughly flushing with clean water under pressure or compressed air. If compressed air is used, provide a filter in airline to ensure that the air is oil-free. If there is an interval of more than 24 hours between cleaning of the sound concrete surfaces that have been contaminated by substances detrimental to good bonding, clean by abrasive shot blasting and pressurized water flushing or remove the concrete.

For vertical and overhead concrete repairs and those horizontal repairs to areas less than 5 inches (130 millimeters) in depth; use a non-shrink grout patching compound placed according to the manufacturer’s recommendations.

For other repairs patches greater than 5 inches (130 millimeters) in depth, apply a bonding coat of an epoxy resin adhesive to the surfaces of the sound existing concrete immediately before placing new concrete against it. Follow the manufacturer’s recommendations for the epoxy resin adhesive. Repair areas using Class A(AE) concrete.

1. Coat side of uncoated aluminum, stainless-steel and lead sheet metal flashing and trim with bituminous coating where flashing and trim will contact wood, ferrous metal, or cementitious construction.

2. Underlayment: Where installing metal flashing directly on cementitious or wood substrates, install a course of felt underlayment and cover with a slip sheet or install a course of polyethylene underlayment.

3. Bed flanges in thick coat of asphalt roofing cement where required for waterproof performance.

C. Install exposed sheet metal flashing and trim without oil canning, buckling, and tool marks.
