Howdy folks,
Received my FB boards, and they are not level in regards to height, have areas that rise and valleys. I have dry stacked my herringbone pattern, and believe there are too many bricks that are not level in regards to each other (varies, but not higher than 1/8" in most spots).
I read many threads on what to use, fire clay/sand, but cannot locate fire clay here in Ohio without a special order and large cost of shipping.
I have heat stop 50 for mortar that I will be using for build, so I will not use the clay for any other purpose.
I tried using just fine sand, but it seems to float the bricks around while setting others, and gets in between bricks, not letting them sit flat together.
I purchased a higher temp clay here in town, it comes in 50# blocks, used for pottery, not sure the exact name, but thought that could be used by adding water and creating a thick slurry, (it comes like pliable putty)then adding find sand, then troweling on as recommended.
I have also seen threads using heat stop/sand instead of fire clay/sand, but also seen that you do not want to mortar down floor.
I am building a 42" oven, have the stand already made, I will be building the dome directly on oven floor.
Any thoughts/ideas would be greatly appreciated.
Thanks,
Pat
