Coating Potable Water Storage Tanks utilizing Plural Component Spray Equipment
Available for download

Current and future coating restrictions that reduce atmospheric emissions as well as the potential for the leaching of chemicals into drinking water systems are pushing tank owners and/or specifiers towards the use of 100% Solids by Volume (SBV) coatings. A majority of these high solids coatings whether epoxy, polyurethane, or polyurea, can or should be and in some instances must be, applied using Plural Component (PC) spray equipment.

 Current and future coating restrictions that reduce atmospheric emissions as well as the potential for the leaching of chemicals into drinking water systems are pushing tank owners and/or specifiers towards the use of 100% Solids by Volume (SBV) coatings. A majority of these high solids coatings whether epoxy, polyurethane, or polyurea, can or should be and in some instances must be, applied using Plural Component (PC) spray equipment. This specialized and complex spray application equipment meters, or ratios, and then mixes the coating material components within the equipment, or at the spray gun. In addition to being a large investment for a contractor, applying coating utilizing PC equipment also requires that the contractor be extremely knowledgeable in its set up and operation, trouble shooting, cleaning and maintenance, as well as being completely aware of the coating’s application characteristics. The equipment should be configured to meet the coating manufacturers’ recommendations to help ensure a problem free application and afford a lining system that will provide the expected long term performance.  This paper will address the basics that individuals will need to prepare for this industry trend.
