The Washington Suburban Sanitary Commission will accept bids Nov. 4 for surface preparation and coatings application on a 2 MG Germantown, MD, water tank commonly called the “Earthoid” tank because of the globe mural on the spheroid-style structure.
The contract includes recoating interior wet surfaces and exterior surfaces, spot-coating interior dry surfaces, and sealing concrete foundation surfaces.
The interior wet surfaces will be abrasive blast-cleaned to a Near White finish (SSPC-SP10) and lined with an epoxy system. The interior dry surfaces will be spot power-tool or abrasive blast-cleaned and spot-coated with epoxy. The exterior surfaces will be abrasive blast-cleaned to a Commercial finish (SSPC-SP6) and coated with a zinc primer, a polyurethane intermediate, and a polyurethane or fluoropolymer finish. The concrete foundation will be coated with a penetrating sealer.
The project also includes applying a new mural to the exterior surfaces. The owner will select between a replication of the current globe or a new baseball pattern.
