Having a good time using this product to aquascape my little terrarium. Used an old paintbrush to smear it all over the bottom to get my carbon base to adhere, also to build my pebble wall that will contain the pool section. Remains pliable and sticky for about 15 mins. Just long enough to get everything how I want it. Would get a larger tube for any big applications. So far very satisfied!
This is just what I needed. I’m glad I searched Amazon instead of going to maybe a hardware store. I was able to search and read for exactly what I was looking for. I used it to seal my cracked ice-machine for our freezer.
I needed a food grade silicone to re seal the gauge in my water tank on my boat, and I needed to be able to apply in 45 - 50 degree weather. This worked perfectly.
I inherited a teacup with a broken saucer from my mother and decided to give it a good fix. This product has held it together for the few months since I’ve fixed it, though I will say that I am still extremely careful with it and never hold it from one of the pieces that broke off, just in case.
Bought to fix the plastic gauge / window thing on the side of an expensive Alexa controlled kettle after it started to leak. Done the job flawlessly. Bonded (like an adhesive) and sealed. Can't notice it aesthetically. The stuff lief in the tube is still soft too, so might be good for something else. Recommended!
