water-safe-1WTB Spray’s WATERSAFE-UB™ potable water coating is in compliance with the test passing requirements of NSF/ANSI Standard 61 Section 5 (2011).  This protective coating is approved for direct contact with potable water while providing a tenacious bond to certain thermoset plastic surfaces.   WATERSAFE-UB™ adheres to many polymeric substrates both new and aged, typically without the use of primers or extensive surface preparation. SPI’s potable water liner is a fast setting, rapid curing, 100% solids, flexible aromatic, two component spray polyurea that can be applied to a variety of substrates including suitably prepared concrete and metal surfaces.  It’s extremely fast set gel time makes it suitable for applications down to -20°F.  It may be applied in single or multiple applications without appreciable sagging and is relatively insensitive to moisture and temperature allowing application in most temperatures.
