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.

I got this to reseal my Daughters shower -- for whatever reason she tried doing it herself -- the Caulk that she used wasn't setting up (she tried two kinds -- evidence out to trash) -- I know she did something wrong but I don't know what -- off to Disney she went while I cleaned the newly placed Caulking and redid her work -- this Silicone caulk had the lowest odor of any that I have used in my 74 years -- it feathered well, cured with no issues and the color matched perfectly (it's not easy to find Gray Caulking locally) -- it has a fairly long workability time so I was able to wipe off the excess without any issues -- I tried tapeing the lines but the tape wouldn't stick to the tiles -- no I didn't clean the tile first -- it's her house, not mine LOL -- I checked two days later -- the Caulk is firmly in place and ready for use -- I would order again but not soon because I'm keeping the second tube for myself -- pro tip: if your caulking gun doesn't have a lever to switch to a no-drip mode I suggest you look into one -- I ordered one at the same time and was really pleased that I didn't have to continually release the pressure after every squeese
