Approximately
128,000 square feet of surfaces was coated following preparation to SSPC-SP6
commercial Blast Cleaning and SSPC-SP3 Power Tool cleaning.
Surfaces

Several different
surfaces of concrete Secondary Containments received flexible, Corrosion
Resistant linings to bridge potential movement of concrete and provide
Corrosion Barrier to aggressive chemicals such as; Concentrated Sulfuric

The old lining
material and E Coat material was removed from main dip tank, weir tank
and pump wells by high pressure water jetting with 36,000 PSI to clean
the steel surfaces to bare metal. All steel surfaces were abrasive blasted
to meet SSPC-SP5 (White Metal) with a three mil minimum anchor profile.
All prepared
surfaces received lining system based on primer and silica filled, glass
reinforced, epoxy lining, applied to a nominal thickness of 3/16"
in accordance with the manufacturer's recommendations and instructions.

Prior to surface preparation all surfaces were evaluated based on the following field tests:
Tensile Strength (ATSM D4541-85)
Moisture Content (ATSM D4263-88)
Surface Temperature
Chloride and Sulfate Ion Contamination
Surface preparation included mechanical methods (blastracking and scarifying) to remove weak concrete, surface laitance.
Immediately after surface preparation surfaces received a coat of KCC Corrosion Control Techni-Plus E 3.2 penetrating Primer/Sealer.
Vertical repairs to fill surface imperfections, cased by air entrainment during concrete pour and opened up by abrasive blasting, were completed utilizing KCC Corrosion Control Epoxy-based Scratch Coat (PR-11) System.
KCC Corrosion Control Techn-Plus EP 250 Epoxy Motar trowel applied to all surface imperfections less 3".
The following surfaces receieved KCC Corrosion barriers based on the Manufacturer recommendations:
Drum Storage Area - Techni-Plus EN 25.5 Broadcast System (80 mils D.F.T.)
Sumps and Trenches - Elast-Liner I.2 (60 mils D.F.T.)
Drain Deck and Tank Pedestals - ElastiLiner III (60 mils D.F.T.)
Chemical Storage Area - ElastiLiner II (40 mils D.F.T.)
Waste Treatment Area - - ElastiLiner II (40 mils D.F.T.)
