Hi,
So I cast my homebrew refractory layer last night approx 20 hours ago some pics attached. It is sitting in the garage at 14 celcius under plastic sheet and have been spritzing it with water to keep it damp. It has hardened to where you can't dent it with your finger but you can make a mark with a fingernail. Is the temp too cool for curing? I've seen other posts saying it has to be hot?
Should I wait longer before removing the form and sand? Once I do should I keep it damp and covered for a week?
Cheers,
J
