Inspect the roof:
check the extent of the damage.
identify areas with the most severe flaking and any exposed rebar.
clean the surface:
remove loose material: use a wire brush or a pressure washer to remove all loose, flaking concrete and any rust from exposed rebar.
clean the surface: ensure the surface is free of debris, dust, and grease. this will help the repair materials adhere better.
treat exposed rebar:
rust converter: apply a rust converter to any exposed rebar. this will neutralize the rust and prevent further corrosion.
rebar primer: after the rust converter has dried, apply a primer specifically designed for rebar to protect it from moisture and further corrosion.
apply a bonding agent:
concrete bonding agent: apply a concrete bonding agent to the cleaned surface. this helps new concrete or repair mortar adhere to the old concrete.
patch the concrete:
repair mortar: use a high-quality concrete repair mortar to fill in areas where the concrete has flaked off. ensure the mortar is well-suited for outdoor use and can bond to existing concrete.
seal the surface:
concrete sealer: once the repair mortar has cured, apply a concrete sealer. choose a sealer that is water-resistant and designed for exterior use. this will protect the concrete from moisture penetration and further damage
