Review: Flexible and Durable Seal - It's an economical and effective solution for sealing joints and cracks where a flexible and durable seal is needed. Its ease of application and resistance to varying conditions make it a solid choice for both DIY projects and general home maintenance.
Review: Professional, durable finish - This caulk is the unsung hero of rodent defense. PI used Akfix 100E RTV Gray Silicone Caulk to seal up the last remaining mouse-sized loopholes, and it did exactly what I needed it to do. It flows smoothly, adheres well, and cures into a tough, flexible seal that says, “This gap is permanently closed.” It’s perfect for those awkward cracks and seams where steel mesh ends or where foam alone just isn’t enough. Once cured, it looks clean, stays put, and gives peace of mind. Combined with proper gap prep, this stuff turns “maybe they can get in” into “absolutely not.” If you’re serious about mouse-proofing and want a professional, durable finish, this silicone caulk gets the job done without fuss.
