Review: great putty - was easy to use for putting around pipes coming out of fridges
Review: Much better than spray foam for small gaps! - "I used this to seal around the electrical conduit where it enters my house, and it was so easy to work with. It’s like a soft modeling clay that stays pliable, so you can really pack it into gaps to stop drafts and bugs. Unlike spray foam, it’s not messy and you can actually remove or adjust it later if you need to. Great price for a very effective product!"

## Questions & Answers

**Q: Is it paintable?**
A: Cannot say. I bought it as a waterproof sealant and for this purpose it works perfectly.

**Q: Is this for 1 lb? Or for 10?**
A: 1 Lb. Was more than enough with plenty left over for other jobs

**Q: Can this be used to patch a hole in the wall around stove gas pipe?**
A: Are you talking about a gas line coming into the stove, I’d say yes it can be. If you’re talking about the actual stove pipe that gets hot then no.

**Q: Would this work to fill a 2 inch hole with electrical wires coming through it that is immersed in hot water?**
A: Yes, the only limit to this material is your wallet and imagination,

### ⭐⭐⭐⭐⭐ Absolutely as described
*by D***N on 29 May 2026*

This is a unique product. It works well to seal up holes in electrical boxes with wire passing through. Easy to knead and shape. Not sticky to the hands but stays in place very well. Too soon to tell but seems like it will stay pliable and not harden. Bottom line a great product for sealing up those holes in the wall through out the house where plumbing or wire passes through.
