Had to spend another 60usd or so on mineral wool + perlite, concrete.
I added around the base and sides to get an area to build up the walls. Kept falling down so had to push the side in with hand as well as flatten with tool to make areas that the next spot could fit on. Got almost half way up and it would collapse, so gonna leave it a day, then finish most of the sides to near the top.
I shoulda bought larger 1" role of insulation in the beginning, but instead i bought three 2in sheets that are like 80cm x 1.2m or something... Anyway. I did read to add some metal wires into the cast for the insulation to.stick (or the front face, can't remember,) and I did too, it kept the insulation down, I didn't put enough though, and the insulation was a bit too thick. Good to know for next time.
It's been a week since the cast. I added the insulation yesterday and a few inch area to build up the perlite cement, I added another layer today around most sides, I'm approaching limit of the walls near me so will be thicker and more insulated on one side and top vs other side.
I'll try to start fires in a few days I hope. Not sure how long I need/should let the percrete dry for, I recall others doing it in layers and then leaving it for a week... Though I also read when you have an Insualtion layer then percrete it doesn't matter as much as the water can escape through insulation.
I'll leave a few days then do the outer cement render layer except for around top, as I want any steam to escape. Right now there will be near 2in + ~4in of percrete. Can't remember the number of buckets ratio I used today so I'll post again when I count it tomorrow.
