Good product
I purchased this item as my fire had started to crack and had a piece of cement come loose.i read other reviews and thought it may have been harder to do than it was. It was easy to apply and pack into the area that had the piece loose. I left it 24 hours to go off before lighting the fire and it's been fine since. Could do with coming in smaller sizes.

Good product
I bought this product to cement in a replacement fireplace hearth. It’s been in about 3 weeks and we’ve used the fire several times. There’s no sign cracks or deterioration. I followed the instructions and it was easy enough to apply.

Great fire cement
Used to rebuild on an Aga fire chamber. I have nothing bad to say and would use again. Also a decent size without the ridiculous cost at the screw and tool places.

Useful stuff - not easy to find
Bit more than I actually needed so most of the tub is wasted. But at least they had some!

Worked for what I needed it for
Used this for a small project using an old BBQ. It has absolutely done the trick. More like a putty, so ended up just putting gloves on and applying it with my hands. Also applied it a bit thick so it didn't cure properly, but patched it with leftovers and worked a dream.
