Coverage is not the same as transfer efficiency

Brushing, wiping and spraying can use very different amounts of material. The coverage printed on the container may assume a smooth, sealed surface and ideal application.

Common reasons a finish runs short

  • End grain and porous surfaces absorb more finish.
  • Spray equipment leaves material in the cup, hose and overspray.
  • Sanding between coats may require another coat.
  • Edges, test panels and touchups are easy to forget.
