Step 1: Layout the block in the shape you want the finished fire pit to be (round or square is most common).  Once you have the first row where you want it, use the tip of your shovel to mark where to dig around the outside of the block.  Move the block and dig a 12 inch deep by 8 inch wide trench where you block was just moved from.  This will act as your foundation for the block.

Step 2: Fill the trench with 6 inches of #57 gravel a compact until stable.  Lay the first course of block directly on the gravel, using a level to make sure it’s level.

Step 3: Use the masonry adhesive and caulk gun to glue the remaining courses of block together.  Adhesive should be applied in zigzag lines along the top of each block. Make sure to offset each block from the blocks below so that the joints between each block are staggered.

Step 4: Once you have placed enough blocks to achieve the height you want, allow the adhesive to dry (see label on adhesive container).  If the blocks are hollow or you want to use a different type of cap block, now is the time to install a cap.  Using a flexible mortar, lay a 1/4″ inch mortar bed along the top of the blocks and place your cap over the mortar.  Once the cap is set, use mortar to fill in any gaps between the cap stones.

Step 5: Fill the bottom of the fire pit ring with 8 inches of gravel and go cut some wood for your first fire!
