## Questions & Answers

**Q: Is this ok to be left out in freezing temperatures overnight before application?**
A: probably not, and is not recommended in the application specifications either. 
Read the specification sheet for the product on the amozon site or on the product site.
I will say the product was VERY easy too use.

**Q: Should I seal up larger cracks before or after applying this?**
A: I would suggest sealing the crack before applying the final top coat of this product. I did that let the sealed crack dry and then did an overall coating with this. Came out great.

**Q: How long will this last on my chimney crown? Can you be more specific than just “years”? (Other products say 15 years.)**
A: couldn't tell you, ask me in 15 years.

**Q: what is the warranty by the manufacturer?**
A: Description says 5 years

### ⭐⭐⭐⭐⭐ Review
*by M***A on 7 April 2022*

Had a cracked crown that really leaked down into the chimney cavity. Found this stuff on Amazon. Got a chimney guy here in Australia to apply it while he was cleaning the chimney. Since then we've had record rain and no leaks so it must be working. The chimney guy in Australia hadn't heard of it before but was really impressed and did a deal where he took the remaining and reduced my bill! Time will tell if it lasts but so far it's saved me at least a few hundred dollars.
