Checking in here. Just poured an 145 sq earthen floor over concrete slab at about 1 1/2” final thikness- 1 1/4” base coat with 1/4” final coat. Looking good so far. Just sourced some oil, solvents and wax from a place called Bioshield out of Santa Fe. I got their “Hard Oil #9” and citrus solvent and liquid wax 😁 I heard about them from my local adobe yard NM Earth Adobes
