Erect initial form

Following the outside of the wall that was marked out in step #5, lay bricks in rows. If you have large seams between your bricks you may want to fill those with hot glue while you erect the formwork. A trowel and a piece of pipe will allow you to clean up your hot glue as you add it to the seams. Alternatively, you can use a thin sheet, potentially produced on a sheetpress, to cover the bricks. This can be taped to the bricks. It does not need to be secured particularly strongly, as the concrete will press it against the bricks tightly when poured.
