Corner piece The Old Mill

With this corner piece you can finish the external corner perfectly. With a joint width of 1 cm, use 32 corner pieces on a corner of, for example, a height of 2.50 m.

Stone height 7, add 1 cm to 8 cm. 2.50 divided by 8 = 32 pieces needed.

The surface area occupied by a corner piece is (internal dimensions of the long and short sides added) 33 cm x 7 high = 0.0231. For example, if you have 32 corner pieces, you will cover 32 x 0.0231 = 0.74 m2
