Xtreme Rain Shield™ is added to conventional Posi-Shell® mix to produce a coating that resists massive rain events immediately after application. Use it when heavy rains are expected within 12 hours of application.
Xtreme Rain Shield™ is a proprietary blend of synthetic polymers whose exposed methyl groups absorb onto the surface of plate-like clay particles, forming bonds that are not easily broken — delivering dramatically improved rain resistance right from the start.
The Posi-Shell® additive that makes your coating rain-resistant from the moment you finish applying it.
Xtreme Rain Shield™ is specifically engineered for situations where heavy rain is expected within 12 hours of Posi-Shell® application — a scenario where standard Posi-Shell® may not have fully cured. The proprietary polymer blend delivers immediate rain resistance without waiting for the normal cure cycle, keeping your cover in place through the storm.
Xtreme Rain Shield™’s synthetic polymer chain contains exposed methyl groups that absorb onto the surface of plate-like clay particles in the Posi-Shell® matrix, forming bonds that are not easily broken by rainfall. This chemistry also improves adhesion to all surfaces — providing a more secure bond between the Posi-Shell® coating and the substrate.
Xtreme Rain Shield™ is a powdered additive blended directly into your conventional Posi-Shell® mix — no separate equipment or application step required. Your existing Posi-Shell® application process remains unchanged; you simply add Xtreme Rain Shield™ to the mix when weather conditions demand it.
