I’ve made a little 8x8x12′ (peak) shed for DW’s electric kiln. On pier blocks; short 6×6 ACQ posts, 2×8 ACQ joists, and 3/4″ ACQ ply decking. Varies from 6-18″ clear from ground; will NOT be underpinned. Steel studs, rafters and roof; Hardi walls
Single room is sealed as tight as foam will make it; will always run a dehumidifier when vents are not open and kiln is firing (pre-firing drying of pieces).
I will put old brick on the floor in a herringbone pattern, and sweep sharp sand into all the joints and edges to lock it up a bit. Brick (100+ years old; our old chimneys) has been stored outside for years; it is damp. After the install, I’ll run the dehumidifier for a while
Should I put #15 tarpaper on the floor first? Poly seems like it would be too slippery for dry-laid brick. I’m thinking about moisture/humidity coming up from the ground – this is GA, after all.
Any input on this??
