Review: It works well and is worth every penny - This stuff really works well. I did a couple of coats an still had a bunch left over. It really does help to lock in the foam. It dried very fast. I would 100% buy again but I won't have to because I still have a bunch. Great deal. Great heat retention. Easy to apply. Really toughens the foam, and it comes in a big bottle!
Review: Works as advertised. - Works as stated in the description. I did a double saturation and it really firmed up the insulation very nicely. I would recommend this size for more than one small project and to maintain the rigidness of my original forge after several uses.

## Questions & Answers

**Q: what is the surface color after it dries?**
A: Exactly the same. I started with white and it was white when I was done, just more rigid.

**Q: Will this prevent kawool particles from getting into the air?**
A: yes  it will help prevent particles from becoming airborne it also adds rigidity to the inner surface to prolong the life of the insulation 
you may need to reapply a few times until you get the desired hardness after it has set and dried ...you can use high heat to speed the dry time up

**Q: Can you reapply a month later after used 3 times?**
A: Yes, as long as you maintain a good seal on the new product and keep it in a cool dry place.

**Q: Do you have an SDS for this product?**
A: This stuff comes from INDIA  so i'm going to guess and say..... 
"I don't know"

Don't drink it or smoke it and use gloves when playing with it and I'm sure you won't grow and extra body part....
