What Is RTV Silicone Sealant?
RTV, or Room Temperature Vulcanizing silicone sealant, is a versatile adhesive that cures at room temperature. Unlike your favorite movie hero, it doesn’t need heat to activate.
It’s commonly used for sealing joints, gaps, and cracks, making it a staple in both DIY and professional projects. You’ll find it in homes, cars, and even aquatic applications. Just remember, not all RTV sealants are created equal. Some stick better to certain surfaces than others, so knowing your project’s material is key.
