Vermiculite Layer

Put the vermiculite/cement mix on, next week I'll cement render over it and that big grey side wall.

I found heaps of different ways of what you should do with the vermicement but this is what i did (which was one of the suggestions) in your wheel barrow put in 6 ten litre buckets of vermiculite, then toss through 1 ten litre bucket of cement until its thoroughly mixed, then using a watering can with a sprinkler rose slowly add water until it all becomes workable/tacky , this for me meant that i could pick it up in a hand ful and not have it crumble.

What actually happened was it took alot more water then i thought to achive this, @ 15+ litres. THEY all say to be careful with adding the water as you do not want to much.

Anyway, i then shoveled it ontop and smoothed it out, they all say don't squash it so at times balls of it ran off like little dung-beetle balls.

what i did was get my square trowl and hold it "downhill" so as i smoothed it down the side i also blocked it from falling off. The bag of vermiculite i bought still has @ a third left in it.

The clay layers have been cold to touch when firing the oven so this layer seems pointless but it was the plan !!
