The Smarter Alternative to Traditional Exterior House Paint Rhino-Shield ceramic coating is a durable, flexible maintenance free exterior house coating, most commonly used in place of exterior house paint. Insulating, weatherproofing, and soundproofing your home are only a few ways Rhino Shield can benefit you. Ceramic microspheres bond together to create a thick, rubber-like texture that bonds to the surface of your home and creates a protective seal. Rhino-Shield ceramic paint alternative, unlike common exterior outdoor paint, offers superior mildew resistance, corrosion resistance, and ultra-violet ray reflectivity. Our ceramic paint alternative requires no maintenance and comes with a 25 year warranty.
