900 Moldable Silicone Putty - Gray Rectangular Shape

I bought this putty to seal the bottom of the standpipe on my outdoor fountain. It was very easy to apply and seems to be working very well.

Love this stuff. So easy to use. I fill small cracks/hole in concrete /cement. Have purchased a couple of times so glad to have found this product.

This is a great product but it's expensive. I needed a small amount for a crack on a plastic shelf in my small fridge's freezer. It worked great, Been holding well without letting moisture getting in and ruining the inner lining. If they offered smaller sizes I would've bought that. It definitely work in freezer temperatures for inquiring minds.

I had to remove a front metal panel to access my air conditioning evaporator on top of my heater. (The coils needed defrosting). All went well, but I had trouble replacing the panel. It would not go into its slot, and the screw holes would not line up. After careful analysis, I realized that I had to completely remove the old putty, reinstall the panel, and and then seal where the pipes came out with new putty. The old putty was still soft, but not very malleable. The E/FUSING 900 Moldable Silicone Putty was very easy to work with, and sealed perfectly. It saved me the cost of a service call. It is clean to work with -- not oily, not smudgy, non-staining, and just the right amount of malleability. I expect it to retain its shape and seal forever. In the photo, the black putty is the E900. The gray putty is the original putty from when the heater and A/C was installed. I WOULD LIKE TO SHARE A LESSON LEARNED: Change your heater-A/C filter frequently enough so that it does not become clogged. Otherwise you can end up with a block of ice around your evaporator coils, reduced flow of cold air, blocked and overflowing condensate drainage and insufficient air conditioning.

This stuff is great for large openings arund doors pipes etc. you have to learn how to use it then it works great and is water proof very white

TINY amount of caulk for the price - see the photo. It works OK but I wouldn’t buy it again due to the absurd price to size ratio. Unless you need to seal the windows on a doll house, look elsewhere for a better value.

Used this to seal/insulate and secure my window AC side panels and it is great stuff. No chemical smell and did not even have to wash my hands after. Excellent install not sure how removal will be in months to years but I am very impressed and this is exactly what I needed to insulate my AC without using permanent applications.

Great product holds up to hot temperatures easy to mold

Product is way too overpriced for the size of product you actually get. Super disappointed.

Excellent moldable putty! Used it for the water fountain and it has held up great!

Funciona bien

Product works superbly for the job I have for it. It prevents leaks in my molds and I will continue to buy and use this putty.

good for sealing stuff but cost wise you might do better going to your local hardware store
