Siliconizer™ 1000 Primer is a ready-to-use, one-part rubber-latex base/membrane that provides an easy alternative toe for waterproofing applications as a base membrane. This flexible monolithic membrane delivers excellent performance when used as a base coat over existing surfaces and performs very well during continuous water immersion testing. It must be covered with a compatible roof coating, applied according to the manufacturer’s specifications, within five days of application to protect it from UV exposure.
