Corners are sold by the linear foot and flats by the square foot. This separates them so you do not pay for both on the same wall.

How it works

Wall area minus openings, minus about 0.75 square feet for each foot of corner, then your extra. Mortar uses about 15 square feet per 80 lb bag.

Before you order

  • Measure outside corners floor to top, since corners are bought by length.
  • Back-butter each piece and press it until mortar squeezes out at the edges.
  • Keep weep screeds and flashing clear so water can leave behind the stone.
