Recon its cost me about £400 up to now. I've got 2 bags of perlite and 2 bags of fire cement 1 bag of vermiculite. I bought some blankets 610mm x 3360x50mm x 2 for £90 delivered. They are only 93 kg not the 127kg that would be better.

Fire brick grog is smashed up fire bricks, crushed to 1mm or above. I used 1mm, it's like dust really.
I don't understand why everyone goes on about home brew.I payed £12-50 for fire cement and same price for grog. So that's £25 for 50kg of materials

I wish I could get materials that cheap. The drawback with calcium aluminate cement is its high cost and reduced working time. Because it's so temperature dependent I usually have to add chilled water to keep it from going off too fast (we live in the tropics) |

Yes it soon goes off,I mixed it more like paste. I've been told that if it comes into contact with portland cement it goes off instantly

I suppose that's the difference between an experienced builder and the rest of us WFOers, the speed of progress. What's the plan for the exterior ? We will of course expect something commensurate with your proven skills !
