## Questions & Answers

**Q: Can I use it to seal holes around the house? I was going to get normal cement,  I want to keep rodents out of the house.**
A: I don't think this is the right thing for that.  It may not harden without heat, or take months to.  I had a rodent problem and was advised to use steel wool.  Mice and rats will chew through nearly anything but the metal kills them before they can break through.  I used fine steel wool chopped up and pulled apart and worked into normal filler compound, and I've also used steel scourers, the sort like a ball of spiral steel swarf.  I worked filler compound into it and the same may be possible with cement.

**Q: Can i use this to secure a rotary washing line in the groung (grass) ?**
A: Good Morning,

Thank you for your enquiry.

This cement ideal for a variety of applications, at The Cosy Owl we recommend using fire cement to seal the connection between any Vitreous Enameled flue pipes and around the Register Plate to ensure no flue gases escape from the system and to prevent heat loss where possible.

If you have any further queries, please do not hesitate to contact me again.

Kindest Regards

Lyndsey

**Q: will it bond cast iron?**
A: No it will only seal !

**Q: Can I use this to repair holes in my fire pit? How would it dry does it have to be heated up?**
A: Hi, Kos Fire Cement is resistant to temperateness upto 1200 C. It is not commonly used for hope repairs, and requires heat to fully cure.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Decent fire cement at a good price.
*by A***A on 21 October 2016*

I needed this fire cement to reseal my daughters cast iron fire surround. The surround had come away from the wall a little and was leaking from the indside, after cleaning the affected area and using a wet sponge to moisten the area I applied the cement as instructed on the tub. It did a perfect job of making a smoke proof seal and once a fire had been set the cement cured to make a permanent fix.This did exactly what I needed and was good value, the instructions are easy to follow, I noticed that the tub had been shrink wrapped to avoid any mishaps during shipping, a nice touch.

### ⭐⭐⭐⭐⭐ Works!
*by S***T on 10 July 2023*

This is better and a lot easier to use than I thought it would be. You do need some muscle power to spread it but once done sets perfectly. Been a while and still happy

### ⭐⭐⭐⭐ Good value, good product
*by A***R on 21 February 2013*

I was a little suspicious that a product at such a low price would be any good. I was wrong. This fire cement is great. It has stayed blacker than the one my chimney sweep uses and hasn't cracked at all. I did make sure I prepared and cleaned the fire and flue well first but I didn't make too much effort to really get a perfect finish, yet it looks pretty good! It is a little coarser than cements I have used before but I am sure you could get a really smooth neat finish if you need it. Job done quickly and effectively at minimal cost and plenty left for future jobs. Fast efficiant delivery too.
