The calculation
Flat veneer = net wall area minus corner coverage
Flat boxes = ceiling(((gross area − openings − corner flat-area credit) × (1 + waste)) ÷ flat coverage per box)
- Outside corner pieces are measured in linear feet and replace an editable amount of flat area.
- Flat and corner package coverage must come from the exact veneer product.
- Mortar coverage should match the substrate, layer, joint style, and complete scope being estimated.
- All material quantities round up to full retail packages.
