New Type 10 White Seal Putty Waterproof Duct Seal Repair Sealing Clay, Quick Mending Mud for Drain Connection, Wall Hole, Air Conditioning Hole

I bought this with the hope the putty would fill the many gaps left in the installation of a window air conditioner without marring any paint touched or the machine parts, yet stay in place and do the job of blocking air, light through the gaps, and insects. It does! It hardens a tiny bit, and didn't shrink as it dried. It really worked well in the base and top of the accordion "wings" that stretch from the machine to the window sides. It looks neat and professional because even if you aren't perfectly even in pressing it in, it magically self-levels. There's no evidence of erosion from the effect of moisture from the outside. All the little seams and spaces are completely filled. When (if) I take the machine out, the putty will be easy to remove, I tested. It leaves no residue. And you get such a generous amount in the ten bags, and don't have to use it all at once due to the individual sealed packages. I'm pretty sure I'll find other uses for it, too.

Bought it to use on shower faucet to fill the gap between the faucet and the wall/tile. Taking it out from the packing is not easy, it is very fluffy but you have to kind of knead it. Then you can put it where you want and smooth it with your hands fingers etc. I also used wet paper towel to smooth and it worked well. Not sure how long it will stay. Let's see. If it stays, I would recommend it.

Had I known there would be no instructions in English I would not have purchased this product. And if you ask questions regarding it on Amazon's website it refers you back to another professional for advice which makes no sense because this came from China and the only writing on it is in Chinese

Used to seal around faucet. But apparently it’s not waterproof as described.

I moved in an old apartment and I use it to cover small holes, (after I sprayed) even around wall sockets because bugs get in everywhere, and since it was like biscuit or play dough I used it as sealant on the bottom of entire floor (where the floor board and floor meet)...in every room even closets, I mean every spot because little worms were getting in and I couldn't figure out where. I also use it to cover behind toilet where the pipe meets wall and around all sink pipes at wall. Again because it's an old apartment things were not like it used to be and bugs come from one apartment to the other from crawling on pipes etc...I have no bugs.My grandson helped because it's like messy biscuit dough but I read some people put in the frig to harden a little but I used it out of the package to spread. Gloves didn't help especially since I had to spread with fingers and it washes off.Note: When it dries it's not hard like the spray foam it's more spongy like texture but it does its job

Just had work done in my house and they left an oversized hole under the sink where little crickets and stuff got in. Tried to spackle it but it was a mess. Saw this and figured I’d give it a try. It was SO EASY. It took less than 5 minutes. Still needs to dry but I’m very hopeful that it will dry as easily as it went on. Very impressed

I wanted to use this for sealing a space between a outside spotlight and the eve. When I opened the package, it basically ran out of the package all over the ground. I should have just used caulk.
