Well I just pored the refractory for the floor, so I just have to cut the boards for the sides and roof then I’ll be lighting it up! I didn’t get anything to coat the board with because I’m close to budget and I have a ton of that board to replace it if I have to. I have 2 2x3 ft boards of it.
Don’t worry we didn’t mix it inside we just moved it downstairs to let it dry in the heat.
