Prepare Floor Edges (Dam)

ready to do our metallic pour out. So, I'm want to create a dam right here so our pore doesn't go, you know, outside onto the concrete. So, I'm just using backer rod. And I'm using T-Rex tape. Two rows of T-Rex tape to create my seam there. Tacking the backer rod to it. And the back of rod creates a nice curved dam so the stuff can hit it and just pull back.
